There were two CA systems compared a conventional tillage system: direct seeding into dead mulch (CA-DM) and into a stylo living mulch (CA-LM). Soil health was evaluated using Biofunctool®, a set of ten in-field tools that assess soil carbon transformation, structure maintenance and nutrient cycling functions. Weeds, maize growth and yield components were monitored using a Structual Equation model (SEM). Soil structure maintenance and nutrient cycling functions were higher under CA-DM and CA-LM than under CT, and carbon transformation function was higher under CA-DM than under CT and CA-LM. Overall, the soil health index (SHI) was 1.3-fold higher under CA systems than under CT. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127822048/2021/10/28/effects-of-conservation-agriculture-maize-based-cropping-systems-on-soil-health-and-crop-performance-in-new-caledonia> <https://www.scoop.it/share/post/twitter/4127822048?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127822048?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127822048?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127822048> A history of conservation agriculture in South Africa. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127794920/2021/10/27/a-history-of-conservation-agriculture-in-south-africa> From www.tandfonline.com <https://www.tandfonline.com/doi/abs/10.1080/02571862.2021.1979112> - October 27, 4:23 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127794920/2021/10/27/a-history-of-conservation-agriculture-in-south-africa> Strauss, J.A., Swanepoel, P.A., Smith, H. & Smit, E.H. 2021.

Because of the numerous benefits, CA is viewed by many as the more sustainable alternative to conventional agricultural practice but cautions there are many challenges associated with CA. This paper explains the basic principles, a brief history, and provides a discussion of the benefits and challenges associated with the approach in South Africa. This paper also serves as an introduction to a Special Issue on conservation agriculture in South Africa. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127794920/2021/10/27/a-history-of-conservation-agriculture-in-south-africa> <https://www.scoop.it/share/post/twitter/4127794920?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127794920?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127794920?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127794920> Long term soil carbon sequestration potential of smallholder croplands in southern Ethiopia with DAYCENT model <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793924/2021/10/27/long-term-soil-carbon-sequestration-potential-of-smallholder-croplands-in-southern-ethiopia-with-daycent-model> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0301479721009555> - October 27, 3:58 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793924/2021/10/27/long-term-soil-carbon-sequestration-potential-of-smallholder-croplands-in-southern-ethiopia-with-daycent-model> Lemma, B., Williams, S. & Paustian, K. 2021.

The management systems considered were minimum tillage, crop residue (CR) retention, fertilization and their combinations.Data came from studies in the literature. The alternate systems were compared with the business as usual treatment (BAU). Results showed CMS increased SOC in the 0-20 cm layer compared to BAU. The individual effect of fertilization, CR retention or minimum tillage management practices on SOC stock were lower than the response of the combined conservation management practices. They conclude that the combined 50–75% CR retention, NT, and increased N fertilization have a potential to increase SOC sequestration in resource-limited smallholding croplands. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793924/2021/10/27/long-term-soil-carbon-sequestration-potential-of-smallholder-croplands-in-southern-ethiopia-with-daycent-model> <https://www.scoop.it/share/post/twitter/4127793924?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127793924?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127793924?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127793924> Relationship between the amounts of surface corn stover mulch and soil mesofauna assemblage varies with the season in cultivated areas of northeastern China <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127766156/2021/10/26/relationship-between-the-amounts-of-surface-corn-stover-mulch-and-soil-mesofauna-assemblage-varies-with-the-season-in-cultivated-areas-of-northeastern-china> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0167198721001641> - October 26, 5:13 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127766156/2021/10/26/relationship-between-the-amounts-of-surface-corn-stover-mulch-and-soil-mesofauna-assemblage-varies-with-the-season-in-cultivated-areas-of-northeastern-china> Jiang, Y., Xie, H. & Chen, Z. 2021.

The treatments were no-till with no corn stover mulch (NT-0); no-till with 2.5 t ha−1 corn stover mulch (NT-33 %); no-till with 5 t ha−1 corn stover mulch (NT-67 %); no-till with 7.5 t ha−1 corn stover mulch (NT-100 %), and conventional tillage (CT) as a control treatment. The abundance, diversity, and composition of the mesofauna were measured to estimate the potential interacting effects on the mesofauna of no-till with different amounts of corn stover mulch. The results showed that compared with CT, no-till with corn stover mulch altered the mesofauna communities and demonstrated that the corn stover mulch was an important factor in supporting more abundant and diverse mesofauna. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127766156/2021/10/26/relationship-between-the-amounts-of-surface-corn-stover-mulch-and-soil-mesofauna-assemblage-varies-with-the-season-in-cultivated-areas-of-northeastern-china> <https://www.scoop.it/share/post/twitter/4127766156?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127766156?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127766156?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127766156> Performance evaluation of a biomimetically designed disc for dense-straw mulched conservation tillage <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127766106/2021/10/26/performance-evaluation-of-a-biomimetically-designed-disc-for-dense-straw-mulched-conservation-tillage> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0167198721001380> - October 26, 4:54 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127766106/2021/10/26/performance-evaluation-of-a-biomimetically-designed-disc-for-dense-straw-mulched-conservation-tillage> Torotwa, I., Ding, Q., Makange, N.R ., Liang, L. & He, R. 2021.

A biomimetic disc mimicking the mole-rat’s claw was fabricated and evaluated in comparison with traditional discs (i.e. a plain and a notched disc) in straw mulched soil. Tests were done at 3 soil depths. The claw-shaped edges easily penetrate through densely mulched soil while avoiding tool-sliding over the straw, and achieves minimum soil disturbance. The biomimetic tool design thus presents a viable solution for the conflicting performance requirements by conservation tillage in intensive farming systems. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127766106/2021/10/26/performance-evaluation-of-a-biomimetically-designed-disc-for-dense-straw-mulched-conservation-tillage> <https://www.scoop.it/share/post/twitter/4127766106?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127766106?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127766106?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127766106> Direct seeded rice in sequence with zero-tillage wheat in north-western India: addressing system-based sustainability issues <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127764047/2021/10/26/direct-seeded-rice-in-sequence-with-zero-tillage-wheat-in-north-western-india-addressing-system-based-sustainability-issues> From link.springer.com <https://link.springer.com/article/10.1007/s42452-021-04827-7> - October 26, 10:48 AM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127764047/2021/10/26/direct-seeded-rice-in-sequence-with-zero-tillage-wheat-in-north-western-india-addressing-system-based-sustainability-issues> Yadav, D.B., Yadav, A., Vats, A.K., Gill, G. & Malik, R.K. 2021.

Weed infestation was more intensified and diversified in direct seeded rice (DSR) than puddled transplanted rice (PTR), and even eliminating puddling in rice-induced more infestation of Phalaris minor in succeeding wheat crop. Residue retention in zero-till (ZT) DSR and rotating conventional till (CT) DSR with PTR reduced weed pressure compared to continuous DSR. Root knot and plant parasitic nematodes were less in DSR than PTR but reverse was true for saprozoic nematodes in DSR and ZT situations. There was also improvement in soil health under ZTDSR/MTR (higher OC, N, P and K, and lower bulk density) compared to PTR. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127764047/2021/10/26/direct-seeded-rice-in-sequence-with-zero-tillage-wheat-in-north-western-india-addressing-system-based-sustainability-issues> <https://www.scoop.it/share/post/twitter/4127764047?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127764047?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127764047?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127764047> Community-embedded experiential learning and adoption of conservation farming practices in Eastern and Southern Africa <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127736660/2021/10/25/community-embedded-experiential-learning-and-adoption-of-conservation-farming-practices-in-eastern-and-southern-africa> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S2211464521000774> - October 25, 3:39 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127736660/2021/10/25/community-embedded-experiential-learning-and-adoption-of-conservation-farming-practices-in-eastern-and-southern-africa> Marenya, P., Usman, M.A. & Rahut, D. 2021.

They use a multinomial choice model to estimate the relative risk ratios (RRR) that measures the probability of adopting CA. They conclude that The positive role of community-based dissemination programs potentially means that the dissemination of conservation agriculture requires investments by governments and development organizations in community learning sites. Investments in experiential (hands-on) and farmer self-learning in farmer education programs may be critical in enabling the diffusion of better farming methods. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127736660/2021/10/25/community-embedded-experiential-learning-and-adoption-of-conservation-farming-practices-in-eastern-and-southern-africa> <https://www.scoop.it/share/post/twitter/4127736660?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127736660?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127736660?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127736660> Conservation agriculture strengthen sustainability of Brazilian grain production and food security <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127672309/2021/10/22/conservation-agriculture-strengthen-sustainability-of-brazilian-grain-production-and-food-security> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0264837721003148> - October 22, 2:52 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127672309/2021/10/22/conservation-agriculture-strengthen-sustainability-of-brazilian-grain-production-and-food-security> Anghinoni, G., Anghinoni, F.B., Tormena, C.A., Braccini, A.L., Mendes, C., Zancanaro, L. & Lal, R. 2021.

They conclude that CA enhanced carbon sequestration, physical and especially biological quality of soil, which caused improved soybean grains yield, protein and flavonoids content and profit. This compares with the traditional annual soybean and maize double crop (Zea mays), that reduced soil physical quality with impacts on food security and agricultural sustainability. Sustainability of Brazilian soybean production can be increased by inserting crop rotations involving cover crops in the rotation cycle. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127672309/2021/10/22/conservation-agriculture-strengthen-sustainability-of-brazilian-grain-production-and-food-security> <https://www.scoop.it/share/post/twitter/4127672309?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127672309?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127672309?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127672309> Short-term dynamic responses of soil properties and soil fauna under contrasting tillage systems <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127794946/2021/10/27/short-term-dynamic-responses-of-soil-properties-and-soil-fauna-under-contrasting-tillage-systems> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0167198721002646> - October 27, 4:34 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127794946/2021/10/27/short-term-dynamic-responses-of-soil-properties-and-soil-fauna-under-contrasting-tillage-systems> Coulibaly, S.F.M., Aubert, M., Brunet, N., Bureau, F., Legras, M. & Chauvat, M. 2022.

Three tillage systems were investigated: conventional tillage (with the soil inverted up to 25 cm depth) reduced tillage (limited to the first 7–8 cm depth) and no-tillage. Collembola and earthworms were sampled at each plot using standard methods. Abiotic parameters (bulk density, SOC stock, Mean Weight Diameter (MWD) and aggregates size) and microflora (microbial and fungal biomass and their activity) were also monitored and used as explaining factors. They conclude that overall, conservation tillage can foster one of the numerous services provided by the soil compartment, namely the soil biodiversity and therefore improve soil quality and health. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127794946/2021/10/27/short-term-dynamic-responses-of-soil-properties-and-soil-fauna-under-contrasting-tillage-systems> <https://www.scoop.it/share/post/twitter/4127794946?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127794946?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127794946?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127794946> Conservation Agriculture in Africa <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793953/2021/10/27/conservation-agriculture-in-africa> From doi.org <https://doi.org/10.1079/9781789245745.0000> - October 27, 4:11 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793953/2021/10/27/conservation-agriculture-in-africa> Mkomwa, S. & Kassam, A.

The book will be available in December 2021. Agriculture in Africa today faces major challenges including increased costs, climate change effects and a need for more sustainable production intensification methods. This book looks at Conservation (no-tillage) agriculture as a major alternative sustainable agriculture practice in Africa including its spread to various African countries in the past decade as more development and research has enabled its extension and uptake. The material was presented at the Second Africa Congress on Conservation Agriculture which was held in Johannesburg, South Africa, 9-12 October 2018. The main theme of the Congress was: Making Climate Smart Agriculture Real in Africa with Conservation Agriculture: <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793953/2021/10/27/conservation-agriculture-in-africa> <https://www.scoop.it/share/post/twitter/4127793953?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127793953?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127793953?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127793953> Permanent Bed Width Has Little Effect on Crop Yield under Rainfed and Irrigated Conditions across Central Mexico <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793880/2021/10/27/permanent-bed-width-has-little-effect-on-crop-yield-under-rainfed-and-irrigated-conditions-across-central-mexico> From www.mdpi.com <https://www.mdpi.com/2077-0472/11/10/930> - October 27, 3:42 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793880/2021/10/27/permanent-bed-width-has-little-effect-on-crop-yield-under-rainfed-and-irrigated-conditions-across-central-mexico> Saldivia-Tejeda, A., Fonteyne, S., Guan, T. & Verhulst, N. 2021.

The study selected 9 sites where 6 were rainfed and 3 irrigated. They found that bed width did not affect crop yield. Therefore, farmers can choose the width suitable for their conditions. Some suggestions were: mechanical weeding was easier in narrow beds, fuel use lower for shaping in wide beds, irrigation water use the same in wide beds and narrow beds where the latter is irrigated with alternate rows. Concentration of residue in windrows of wide beds easier. Also suggested soil texture important since it affects infiltration of water. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127793880/2021/10/27/permanent-bed-width-has-little-effect-on-crop-yield-under-rainfed-and-irrigated-conditions-across-central-mexico> <https://www.scoop.it/share/post/twitter/4127793880?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127793880?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127793880?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127793880> Visualising adoption processes through a stepwise framework: A case study of mechanisation on the Nepal Terai <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127765821/2021/10/26/visualising-adoption-processes-through-a-stepwise-framework-a-case-study-of-mechanisation-on-the-nepal-terai> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0308521X21001530> - October 26, 5:05 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127765821/2021/10/26/visualising-adoption-processes-through-a-stepwise-framework-a-case-study-of-mechanisation-on-the-nepal-terai> Brown, B., Paudel, G.P. & Krupnik, T.J. 2021.

Yet Nepal has yet to see substantial mechanization in agriculture. This research aimed to provide a baseline to understand progress made towards Agri-mechanisation on the Nepal Terai. They used a non-binary ‘Stepwise Process of Mechanisation’ framework for this investigation. Across nearly all machinery, a primary reason for limited progression to sustained adoption was a lack of service providers, a manifestation of limited machinery ownership, meaning current broad subsidy programs aimed at procurement may not be achieving intended outcomes. With targeted intervention, rapid rural mechanisation is possible in the near future in Nepal. This work lays the foundation for future work to explore the drivers, implications and inclusiveness of agri-mechanisation, utilising the identified typologies, both in Nepal and more broadly where increased nuance in understanding the status of agricultural mechanisation is warranted. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127765821/2021/10/26/visualising-adoption-processes-through-a-stepwise-framework-a-case-study-of-mechanisation-on-the-nepal-terai> <https://www.scoop.it/share/post/twitter/4127765821?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127765821?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127765821?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127765821> Conservation tillage and nutrient management practices in summer rice (Oryza sativa L.) favoured root growth and phenotypic plasticity of succeeding winter pea (Pisum sativumL.) under eastern Himal... <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127767029/2021/10/26/conservation-tillage-and-nutrient-management-practices-in-summer-rice-oryza-sativa-l-favoured-root-growth-and-phenotypic-plasticity-of-succeeding-winter-pea-pisum-sativuml-under-eastern-himal> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S2405844021011816> - October 26, 4:46 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127767029/2021/10/26/conservation-tillage-and-nutrient-management-practices-in-summer-rice-oryza-sativa-l-favoured-root-growth-and-phenotypic-plasticity-of-succeeding-winter-pea-pisum-sativuml-under-eastern-himal> Das, A., Rangappa, K., Basavaraj, M., Haloi, M., Layek, J., Idapuganti, R., Lal, R., Desmukh, N.A., Yadav, G.S., Babu, S. & Ngachan, S. 2021.

Increased root exudation was observed under NT and MT (minimum till) along with organic residue addition. Also, enhanced chlorophyll pigmentation and favourable leaf characteristics were observed in the pea crop grown under NT with 50% NPK+weed biomass (WB)/green leaf manure (GLM) applications. They conclude that adoption of MT/NT along with 50% NPK+WB/GLM in summer rice is recommended for inducing favourable root environment and optimised pea production in succeeding winter season in study region of the Eastern Himalayas, <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127767029/2021/10/26/conservation-tillage-and-nutrient-management-practices-in-summer-rice-oryza-sativa-l-favoured-root-growth-and-phenotypic-plasticity-of-succeeding-winter-pea-pisum-sativuml-under-eastern-himal> <https://www.scoop.it/share/post/twitter/4127767029?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127767029?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127767029?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127767029> Five years integrated crop management in direct seeded rice–zero till wheat rotation of north-western India: Effects on soil carbon dynamics, crop yields, water productivity and economic profitability <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127761686/2021/10/26/five-years-integrated-crop-management-in-direct-seeded-rice-zero-till-wheat-rotation-of-north-western-india-effects-on-soil-carbon-dynamics-crop-yields-water-productivity-and-economic-profitability> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0167880921001961> - October 26, 10:28 AM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127761686/2021/10/26/five-years-integrated-crop-management-in-direct-seeded-rice-zero-till-wheat-rotation-of-north-western-india-effects-on-soil-carbon-dynamics-crop-yields-water-productivity-and-economic-profitability> Biswakarma, N., Pooniya, V., Zhiipao, R.R., Kumar, D., Verma, A.K., Shivay, Y.S., Lama, A., Choudhary, A.K., Meena, M.C., Bana, R.S., Pal, M., Das, K., Sudhishra, S., Jat, R.D. & Swarnalaksmi, K. 2021.

The various ICM's evaluated were ICM1&2- conventional transplanted rice fb flatbed wheat (check), ICM3&4- conventional direct seeded rice (DSR) fb furrow irrigated raised bed wheat without residues, ICM5&6- conservation agriculture (CA)-based modules [zero tilled (ZT) DSR and ZT wheat] with the wheat and rice residues, and ICM7&8- CA-based modules (ZTDSR and ZT wheat) with wheat, mungbean and rice residues. They conclude that it is important to to have adequate input integration and adoption of CA based ICM's, especially ICM 7&8, improved the soil carbon dynamics, crop yields, farm profits, and provided water savings <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127761686/2021/10/26/five-years-integrated-crop-management-in-direct-seeded-rice-zero-till-wheat-rotation-of-north-western-india-effects-on-soil-carbon-dynamics-crop-yields-water-productivity-and-economic-profitability> <https://www.scoop.it/share/post/twitter/4127761686?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127761686?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127761686?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127761686> Weed shift and community diversity in conservation and conventional agriculture systems in pigeonpea-castor systems under rainfed semi-arid tropics <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127671498/2021/10/22/weed-shift-and-community-diversity-in-conservation-and-conventional-agriculture-systems-in-pigeonpea-castor-systems-under-rainfed-semi-arid-tropics> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0167198721001458> - October 22, 3:06 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127671498/2021/10/22/weed-shift-and-community-diversity-in-conservation-and-conventional-agriculture-systems-in-pigeonpea-castor-systems-under-rainfed-semi-arid-tropics> Pratibha, G., Rao, K.V., Srinivas, I., Raju, B.M.K., Arun, K.S., Madhavi, M., Indoria, A.K., Rao, M.S., Keshava, M., Reddy, K.S., Rao, C.S., Biswas, A.K. & Chaudhari, S.K. 2021.

Results show that annual weed species were dominant in conventional tillage (CT) and reduced tillage (RT), whereas a shift towards perennials was observed in zero tillage (ZT). CT recorded lower weed densities after 7 years. A shift in dicot weed species with higher weed density and biomass and a small decrease in monocot weeds was observed in ZT. The anchored residues 10 and 30 cm, recorded lower monocots and total weed count over no residue. They conclude that integrated weed management (combination of herbicide and removal of chance weeds) are efficient strategies to minimise the weed infestation in CA and these methods not only reduce the over reliance on herbicides but also improve the productivity of pigeon pea (Cajanus cajan L.), castor (Ricinus communis). <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127671498/2021/10/22/weed-shift-and-community-diversity-in-conservation-and-conventional-agriculture-systems-in-pigeonpea-castor-systems-under-rainfed-semi-arid-tropics> <https://www.scoop.it/share/post/twitter/4127671498?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127671498?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127671498?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127671498> <https://drive.google.com/u/0/settings/storage?hl=en&utm_medium=web&utm_source=gmail&utm_campaign=storage_meter&utm_content=storage_normal> <https://www.google.com/intl/en/policies/terms/> <https://www.google.com/intl/en/policies/privacy/> <https://www.google.com/gmail/about/policy/> ######################################################################## To unsubscribe from the CA-Cop-L list, click the following link: &*TICKET_URL(CA-Cop-L,SIGNOFF);
