It contains data for 43 agroecosystem properties and determines overall multifunctionality. Organic production resulted in higher economic performance, thanks to higher product prices and additional support payments. Our results demonstrate that different cropping systems provide opposing services, enforcing the productivity-environmental protection dilemma for agroecosystem functioning. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127038102/2021/09/23/organic-and-conservation-agriculture-promote-ecosystem-multifunctionality> <https://www.scoop.it/share/post/twitter/4127038102?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127038102?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127038102?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127038102> Intensifying cropping systems through doubled-up legumes in Eastern Zambia. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127035993/2021/09/23/intensifying-cropping-systems-through-doubled-up-legumes-in-eastern-zambia> From www.nature.com <https://www.nature.com/articles/s41598-021-87594-0> - Today, 10:32 AM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127035993/2021/09/23/intensifying-cropping-systems-through-doubled-up-legumes-in-eastern-zambia> Mwila, M., Mhlanga, B. & Thierfelder, C. 2021.

The study looks at legume intensification as a possible way to make CA more attractive. Rotations of maize with intensified legume systems were tested for three consecutive years under ridge and furrow (RF) tillage and CA to investigate: (a) increases in productivity of legumes and the subsequent maize crop; (b) changes in land equivalent ratios (LERs) and; (c) improved total system productivity. They conclude that the doubled-up legumes systems have great potential to improve household food security when integrated into current smallholder farming. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127035993/2021/09/23/intensifying-cropping-systems-through-doubled-up-legumes-in-eastern-zambia> <https://www.scoop.it/share/post/twitter/4127035993?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127035993?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127035993?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127035993> Influence of conservation tillage on Greenhouse gas fluxes and crop productivity in spring-wheat agroecosystems on the Loess Plateau of China <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018713/2021/09/22/influence-of-conservation-tillage-on-greenhouse-gas-fluxes-and-crop-productivity-in-spring-wheat-agroecosystems-on-the-loess-plateau-of-china> September 22, 2:44 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018713/2021/09/22/influence-of-conservation-tillage-on-greenhouse-gas-fluxes-and-crop-productivity-in-spring-wheat-agroecosystems-on-the-loess-plateau-of-china> Alhassan, A.M., Yang, C., Ma, A.M. & Li, G. 2021.

All three CA practices (CTS, NTand NTS) markedly increased soil water content (SWC), soil organic carbon (SOC) and soil total nitrogen (STN) but reduced soil temperature (ST). CTS, NT and NTS yields increased by approximately 33%, 9% and 41% respectively compared with CT without residue. There were significant reductions of Net CO2 emissions under NT and NTS compared with CTS and CT. Sustainable soil moisture improvement practices such as no-till, straw mulch, green manuring, contour ploughing and terracing can improve crop resilience to climate change and reduce GHG emissions in arid and semi-arid regions. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018713/2021/09/22/influence-of-conservation-tillage-on-greenhouse-gas-fluxes-and-crop-productivity-in-spring-wheat-agroecosystems-on-the-loess-plateau-of-china> <https://www.scoop.it/share/post/twitter/4127018713?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127018713?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127018713?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127018713> Weed species diversity and shifts in conservation agriculture-based crop rotation systems on the Highveld area of South Africa. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018611/2021/09/22/weed-species-diversity-and-shifts-in-conservation-agriculture-based-crop-rotation-systems-on-the-highveld-area-of-south-africa> From www.tandfonline.com <https://www.tandfonline.com/doi/abs/10.1080/02571862.2020.1813823> - September 22, 2:15 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018611/2021/09/22/weed-species-diversity-and-shifts-in-conservation-agriculture-based-crop-rotation-systems-on-the-highveld-area-of-south-africa> Hugo, E., Craven, M. & Nel, A.A. 2021.

Weeds vary greatly in CA systems since they react differently to different habitats. This research observed the species diversity and shifts in different CA rotations. Monoculture maize (MM) under both conventional tillage (CT) and CA crop systems was accordingly evaluated against two-year and three-year rotation CA systems of maize with cowpea and sunflower respectively. Weed species diversity remained constant across seasons. Some weed species shifts were observed in sandy loam soil site. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018611/2021/09/22/weed-species-diversity-and-shifts-in-conservation-agriculture-based-crop-rotation-systems-on-the-highveld-area-of-south-africa> <https://www.scoop.it/share/post/twitter/4127018611?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127018611?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127018611?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127018611> Conservation agriculture increases the soil resilience and cotton yield stability in climate extremes of the southeast US <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018228/2021/09/22/conservation-agriculture-increases-the-soil-resilience-and-cotton-yield-stability-in-climate-extremes-of-the-southeast-us> From www.nature.com <https://www.nature.com/articles/s43247-021-00223-6> - September 22, 12:10 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018228/2021/09/22/conservation-agriculture-increases-the-soil-resilience-and-cotton-yield-stability-in-climate-extremes-of-the-southeast-us> Nouri, A., Yoder, D.C., Raji, Md., Ceylan, S., Jagadamma, S., Lee, J., Walker, F.R., Yin, X., Fitzpatrick, J., Trexlar, B., Arelli, P. & Saxton, A.M. 2021.

They analyzed 29-years of climate data, cotton yield, and soil data under 32 management practices in Tennessee, USA. They found that long-term no-tillage enhanced agroecosystem resilience and yield stability under climate extremes and maximized yield under favorable climate tied to enhanced soil structural stability and organic carbon. No-tillage enhanced the effectiveness of a legume cover crop in stabilizing cotton yield during relatively dry or wet, and dry years, while nitrogen fertilizer rate and precipitation timing, controlled yield stability in wetter years. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018228/2021/09/22/conservation-agriculture-increases-the-soil-resilience-and-cotton-yield-stability-in-climate-extremes-of-the-southeast-us> <https://www.scoop.it/share/post/twitter/4127018228?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127018228?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127018228?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127018228> Climate-Smart Innovations and Rural Poverty in Ethiopia: Exploring Impacts and Pathways <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126998109/2021/09/21/climate-smart-innovations-and-rural-poverty-in-ethiopia-exploring-impacts-and-pathways> From doi.org <https://doi.org/10.1111/ajae.12161> - September 21, 4:52 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126998109/2021/09/21/climate-smart-innovations-and-rural-poverty-in-ethiopia-exploring-impacts-and-pathways> Tesfaye, W., Blalock, G. & Tirivayi, N. 2021.

They use a panel data endogenous switching regression model to deal with selection bias and farmer heterogeneity in CA choice. The study finds that the CA practices that play a pivotal role in addressing the exigencies of rural poverty are minimum tillage, cereal-legume intercropping, and their combination. These practices reduce the incidence and depth of poverty in areas prone to rainfall stress, which is an indication of their risk mitigation role. They caution against exaggerated expectations of CA's economic benefits and a rigid recommendation of CA. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126998109/2021/09/21/climate-smart-innovations-and-rural-poverty-in-ethiopia-exploring-impacts-and-pathways> <https://www.scoop.it/share/post/twitter/4126998109?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4126998109?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4126998109?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4126998109> Turn the wheel from waste to wealth: Economic and environmental gain of sustainable rice straw management practices over field burning in reference to India <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997768/2021/09/21/turn-the-wheel-from-waste-to-wealth-economic-and-environmental-gain-of-sustainable-rice-straw-management-practices-over-field-burning-in-reference-to-india> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/articleSelectSinglePerm?Redirect=https://www.sciencedirect.com/science/article/pii/S0048969721009633?via%3Dihub&key=4cc9c2d09d2a393897f736227ca8235e80c831e3> - September 21, 2:18 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997768/2021/09/21/turn-the-wheel-from-waste-to-wealth-economic-and-environmental-gain-of-sustainable-rice-straw-management-practices-over-field-burning-in-reference-to-india> Bhattacharyya, P., Bisen, J., Bhaduri, D., Priyadarsini, S., Munda, S., Chaktraborti, M., Adak, T., Panneerselvam, P., Mukherjee, A.K., Swain, S.L., Dash, P.K., Padhy, S.R., Nayak, A.K., Pathak, H., Kumar, S. & Nimbrayan, P. 2021.

Once a wealth, the straw has become a waste subjected to burning due to technical, structural, institutional, and socioeconomic challenges. This paper describes multiple alternate uses of this biomass instead of burning including its use in CA management. The economic and environmental gains and losses of alternate straw management options were estimated and shown to be economic and provide an environmental gain and give a key insight to policy makers to tackle this complex issue of straw-burning. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997768/2021/09/21/turn-the-wheel-from-waste-to-wealth-economic-and-environmental-gain-of-sustainable-rice-straw-management-practices-over-field-burning-in-reference-to-india> <https://www.scoop.it/share/post/twitter/4126997768?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4126997768?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4126997768?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4126997768> Sustaining the properties of black soil in Central India through crop residue management in a conservation-agriculture-based soybean-wheat system <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997721/2021/09/21/sustaining-the-properties-of-black-soil-in-central-india-through-crop-residue-management-in-a-conservation-agriculture-based-soybean-wheat-system> From doi.org <https://doi.org/10.1002/ldr.3891> - September 21, 1:53 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997721/2021/09/21/sustaining-the-properties-of-black-soil-in-central-india-through-crop-residue-management-in-a-conservation-agriculture-based-soybean-wheat-system> Yadav, D., Vishwakarma, A.K., Sharma, N.K., Biswas, A.K., Ojasvi, P.R., Kumar, D., Kumawat, A. & Singh, D. 2021.

Retention of soybean and wheat residues in black soils under a no-till system is important to protect the land from degradation. The main objective of this study was to test the effect of different levels of soybean and wheat residue retention on the physical, chemical, and biological properties of black soil. Four levels of soybean and wheat residue retention (no residue, 30, 60, and 90%) on soil properties was evaluated. Soil organic carbon (C) significantly increased from 0.67 to 1.0% in 5 years through 90% residue retention. Retention of 90% soybean and wheat residues (7.0 and 13.8 t ha, respectively) significantly improved the physical, chemical, and biological properties of black soil in 5 years, therefore protected the soil from degradation. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997721/2021/09/21/sustaining-the-properties-of-black-soil-in-central-india-through-crop-residue-management-in-a-conservation-agriculture-based-soybean-wheat-system> <https://www.scoop.it/share/post/twitter/4126997721?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4126997721?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4126997721?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4126997721> Chiselling and wheeling on sandy loam long-term no-tillage soil: compressibility and load bearing capacity <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127036913/2021/09/23/chiselling-and-wheeling-on-sandy-loam-long-term-no-tillage-soil-compressibility-and-load-bearing-capacity> Today, 10:44 AM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127036913/2021/09/23/chiselling-and-wheeling-on-sandy-loam-long-term-no-tillage-soil-compressibility-and-load-bearing-capacity> Peres da Rosa, D., Reichart, J.M., Lima, E.M. & Trevisian da Rosa, V. 2021.

This paper evaluates tillage and wheeling effects on physical properties of soils. The treatments were 13 years of no-tillage (NT), NT compacted with additional wheeling (NTc), minimum tillage (chiselling) soil (MT), and MT compacted with additional wheeling (MTc). Soil bulk density (Bd), macroporosity (Mp), precompression stress (sigma p), compressibility coefficient (Cc), and relative deformation were determined in four soil layers. Surface compaction in conservation agriculture is a major issue, since soil mobilisation by soil tillage should be avoided. Adding the residue mulch component of CA would have been an interesting additional treatment since other studies have shown that NT and mulch is better than just NT. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127036913/2021/09/23/chiselling-and-wheeling-on-sandy-loam-long-term-no-tillage-soil-compressibility-and-load-bearing-capacity> <https://www.scoop.it/share/post/twitter/4127036913?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127036913?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127036913?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127036913> Recarbonizing global soils – A technical manual of recommended management practices <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127035956/2021/09/23/recarbonizing-global-soils-a-technical-manual-of-recommended-management-practices> From www.fao.org <http://www.fao.org/documents/card/en/c/cb6386en/> - Today, 10:23 AM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127035956/2021/09/23/recarbonizing-global-soils-a-technical-manual-of-recommended-management-practices> FAO and ITPS. 2021.

They analyze roles, organizational capacity and collaboration of stakeholders in Malawi's CA innovation system. NGOs dominate the national CA agenda, while smallholder farmers remain passive recipients of CA interventions. Many CA promoters lack technical and financial capacity, and pursue limited collaboration, which diminish prospects of inclusive stakeholder engagement. Their findings indicate a need to: (1) strengthen understanding of AIS approaches among CA innovation system stakeholders; (2) build stronger partnerships in CA research and development by strengthening stakeholder platforms and social processes; (3) strengthen collaboration advisory mechanisms to facilitate knowledge-sharing, resource mobilization and joint programme implementation with strengthened feedback loops. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127019720/2021/09/22/strengthening-conservation-agriculture-innovation-systems-in-sub-saharan-africa-lessons-from-a-stakeholder-analysis> <https://www.scoop.it/share/post/twitter/4127019720?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127019720?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127019720?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127019720> Soil respiration and net carbon flux response to long-term reduced/no-tillage with and without residues in a wheat-maize cropping system <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018569/2021/09/22/soil-respiration-and-net-carbon-flux-response-to-long-term-reduced-no-tillage-with-and-without-residues-in-a-wheat-maize-cropping-system> September 22, 2:04 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018569/2021/09/22/soil-respiration-and-net-carbon-flux-response-to-long-term-reduced-no-tillage-with-and-without-residues-in-a-wheat-maize-cropping-system> Zhang, X., Xin, X., Yang, W., Ding, S., Ren, G., Li, M. & Zhu, A. 2021.

Compared with continuous tillage, the reduced/no-tillage without residue significantly reduced soil respiration rate. C emission was ascribed to the accumulation of organic C, especially for the labile fraction, under residue returning than under residue removing. The increased organic C stock in topsoil accounted for the accelerated respiration C emission under reduced/no-tillage with residues. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127018569/2021/09/22/soil-respiration-and-net-carbon-flux-response-to-long-term-reduced-no-tillage-with-and-without-residues-in-a-wheat-maize-cropping-system> <https://www.scoop.it/share/post/twitter/4127018569?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127018569?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127018569?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127018569> Chapter 21: Use of Herbicide and Its Implications Under No-Till Farming: An Overview <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127017277/2021/09/22/chapter-21-use-of-herbicide-and-its-implications-under-no-till-farming-an-overview> September 22, 11:59 AM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127017277/2021/09/22/chapter-21-use-of-herbicide-and-its-implications-under-no-till-farming-an-overview> Maheswari, S.T. 2021.

The author describes how NT is becoming a recognized way to grow crops and and practice farming. The chapter goes on to describe the role of herbicides in controlling weeds in NT farming. The use of herbicides has been increasing in India due to shortages of farm labor and concerns about the affordability of labor costs and are the primary drivers for the growing popularity of agrochemicals and herbicides, which is expected to emerge as a key growth segment. But herbicides are not the only way to control weeds and an integrated approach should be used. Proper equipment and training in proper use is also needed. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4127017277/2021/09/22/chapter-21-use-of-herbicide-and-its-implications-under-no-till-farming-an-overview> <https://www.scoop.it/share/post/twitter/4127017277?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4127017277?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4127017277?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4127017277> Conservation agriculture practices have changed habitat use by rodent pests: implications for management of feral house mice. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126998004/2021/09/21/conservation-agriculture-practices-have-changed-habitat-use-by-rodent-pests-implications-for-management-of-feral-house-mice> From link.springer.com <https://link.springer.com/article/10.1007/s10340-021-01370-7> - September 21, 3:26 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126998004/2021/09/21/conservation-agriculture-practices-have-changed-habitat-use-by-rodent-pests-implications-for-management-of-feral-house-mice> Ruscoe, W.A., Brown, P.R., Henry, S., van de Weyer, N., Robinson, F., Hinds, L.A. & Singleton, G.R. 2021.

This study was justified since irregular outbreaks of mice in grain cropping regions in Australia and the damage they cause, makes it important to understand when and where mouse populations increase so that management strategies can be improved. They utilised a 20-year long-term mouse population data set collected prior to the introduction of CA farming practices and a more recent 8-year data set after CA to compare changes in mouse population abundance in a typical dryland grain cropping system in Australia. Mice are now resident year-round within crops and stubble and appear to only spill over into margin habitats. Previously developed recommendations for mouse management that include their control while in margin habitats may no longer be valid. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126998004/2021/09/21/conservation-agriculture-practices-have-changed-habitat-use-by-rodent-pests-implications-for-management-of-feral-house-mice> <https://www.scoop.it/share/post/twitter/4126998004?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4126998004?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4126998004?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4126998004> Contribution of Conservation Agriculture to Soil Security <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997739/2021/09/21/contribution-of-conservation-agriculture-to-soil-security> From www.mdpi.com <https://www.mdpi.com/2071-1050/13/17/9857> - September 21, 2:02 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4126997739/2021/09/21/contribution-of-conservation-agriculture-to-soil-security> Mugandani, R., Mwadzingeni, L. & Mafongoya, P. 2021.
