A Denitrification Decomposition model (DNDC) was used with the data collected and then applied to simulate the changes of crop yields, soil organic carbon (SOC), and N2O emissions under different management practices combined with climate change scenarios, under low and high emission scenarios of societal development pathways (SSP245 and SSP585, respectively) with climate projections from 2031 to 2100. They conclude that CA can potentially offset crop yield reductions, increase soil quality, and reduce greenhouse gas emissions in the NCP, and ensure crop production to meet the growing demand for food under future climate change. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131141065/2022/03/27/can-conservation-agriculture-mitigate-climate-change-and-reduce-environmental-impacts-for-intensive-cropping-systems-in-north-china-plain> <https://www.scoop.it/share/post/twitter/4131141065?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131141065?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131141065?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131141065> Long term effects of tillage and fertilization upon microbiota of a Romanian Chernozem under maize monoculture. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131142023/2022/03/27/long-term-effects-of-tillage-and-fertilization-upon-microbiota-of-a-romanian-chernozem-under-maize-monoculture> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S2352009421001085> - Today, 3:09 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131142023/2022/03/27/long-term-effects-of-tillage-and-fertilization-upon-microbiota-of-a-romanian-chernozem-under-maize-monoculture> Domnariu, H., Postolache, C., Avramescu, S., Lacatusu, A.R. & Partal, E.

A nearby grassland area was used as a check. Measures of overall microbial biomass carbon (Cmic) for community size and ergosterol as a proxy for saprophytic biomass were taken. The Cmic/ergosterol ratio was used to determine community structure. Results showed that no till is characterized by an increase in Cmic compared to chisel and mouldboard plough (+31% and + 16%, respectively). Cmic of the grassland was more than double the microbial biomass of experimental plots. Ergosterol concentration showed the same tendency as overall microbial biomass across tillage treatments, however the impact was statistically significant only between zero tillage and chisel plough (+51%). Moderate nitrogen fertilization (60 kg/ha) induced no significant effect whatsoever, a consequence that is attributed to the rather low dose applied. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131142023/2022/03/27/long-term-effects-of-tillage-and-fertilization-upon-microbiota-of-a-romanian-chernozem-under-maize-monoculture> <https://www.scoop.it/share/post/twitter/4131142023?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131142023?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131142023?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131142023> Smart subsidies for sustainable soils: Evidence from a randomized controlled trial in southern Malawi. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131138922/2022/03/27/smart-subsidies-for-sustainable-soils-evidence-from-a-randomized-controlled-trial-in-southern-malawi> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0095069621001108> - Today, 2:07 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131138922/2022/03/27/smart-subsidies-for-sustainable-soils-evidence-from-a-randomized-controlled-trial-in-southern-malawi> Ward, P.S., Mapemba, L. & Bell, A.R. 2021.

By providing financial incentives, this paper demonstrates that it is possible to increase the extent and intensity of CA adoption. Also mechanisms that leverage social networks for the consolidation of fragmented land may be more effective at bringing more land under conservation objectives. They also demonstrate that some of the supposed weaknesses hindering the adoption of CA – lower yields in the short-run and higher expenditures on weed control – were not necessarily obstacles in their study area. They suggest that the provision of subsidies need not continue into perpetuity, but may only be needed to overcome short-term transition costs. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131138922/2022/03/27/smart-subsidies-for-sustainable-soils-evidence-from-a-randomized-controlled-trial-in-southern-malawi> <https://www.scoop.it/share/post/twitter/4131138922?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131138922?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131138922?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131138922> Eukaryotes in soil aggregates across conservation managements: Major roles of protists, fungi and taxa linkages in soil structuring and C stock <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131129852/2022/03/26/eukaryotes-in-soil-aggregates-across-conservation-managements-major-roles-of-protists-fungi-and-taxa-linkages-in-soil-structuring-and-c-stock> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0038071721003370> - March 26, 4:57 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131129852/2022/03/26/eukaryotes-in-soil-aggregates-across-conservation-managements-major-roles-of-protists-fungi-and-taxa-linkages-in-soil-structuring-and-c-stock> Pellegrino, E., Piazza, G., Helgason, T. & Ercoli, L. 2021.

There were 3 tillage treatments; CT, RT and NT, with and without residue retention. Energy consumption ranged from 51.87 GJ ha−1 (ZT-R) to 64.91 GJ ha−1 (CT + R) and irrigation water was the major energy intensive input (41–44%) followed by chemical fertilizer (32–40%). Overall, switching from CT–R to ZT + R lowered energy consumption (19%), GHG emission (16%) and carbon footprint (78%), making it the best-bet option for climate change mitigation and global warming related environmental protection. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131141054/2022/03/27/energy-efficiency-and-carbon-footprints-of-rice-wheat-system-under-long-term-tillage-and-residue-management-practices-in-western-indo-gangetic-plains-in-india> <https://www.scoop.it/share/post/twitter/4131141054?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131141054?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131141054?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131141054> Evaluating Climate-Smart Agriculture as Route to Building Climate Resilience in African Food Systems. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131139975/2022/03/27/evaluating-climate-smart-agriculture-as-route-to-building-climate-resilience-in-african-food-systems> From www.mdpi.com <https://www.mdpi.com/2071-1050/13/17/9909> - Today, 2:55 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131139975/2022/03/27/evaluating-climate-smart-agriculture-as-route-to-building-climate-resilience-in-african-food-systems> Dougill, A.J., Hermans, T.D.G., Eze, S., Antwi-Agyel, P. & Sallu, S.M. 2021.

The two tillage treatments were CT with residues incorporated and NT with surface residues with both combined with controlled traffic. There were also two irrigation treatments; full (FL) and regulated deficit (RDI). Results showed that in the short term, soil CO2 effluxes were higher in CTR than in ZTR after soil preparation and during crop growth, although only significantly in the first case. However, accumulated CO2 emission during the cropping period (163 days) was 1.8 times higher for CTR than ZTR (2126 and 1177 g m−2, respectively). NT plus controlled traffic reduced CO2 emissions. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131129869/2022/03/26/effects-of-conservation-tillage-controlled-traffic-and-regulated-deficit-irrigation-on-soil-co2-emissions-in-a-maize-based-system-in-mediterranean-conditions> <https://www.scoop.it/share/post/twitter/4131129869?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131129869?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131129869?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131129869> Dry sowing reduced durum wheat performance under irrigated conservation agriculture <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131126951/2022/03/26/dry-sowing-reduced-durum-wheat-performance-under-irrigated-conservation-agriculture> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0378429021002562> - March 26, 12:17 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131126951/2022/03/26/dry-sowing-reduced-durum-wheat-performance-under-irrigated-conservation-agriculture> Grahmann, K., Honsdorf, N., Crossa, J., Beltran, G.A., Govaerts, B. & Verhulst, N. 2021.

It also looks at pre-irrigation (wet) and post-irrigation (dry) strategies in Durum wheat comparing conventional tillage and PBP (NT). They used 4 tillage-sowing irrigation and 5 nitrogen treatments over 3 years. The lowest germination was found in PBP-dry and the lowest yield. N fertilization management affected wheat quality, but not wheat yield, possibly due to high levels of soil mineral N available at sowing that were not measured in this study. They suggest research should address reduced plant stands with dry sowing in conservation agriculture to find management options that improve wheat emergence. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131126951/2022/03/26/dry-sowing-reduced-durum-wheat-performance-under-irrigated-conservation-agriculture> <https://www.scoop.it/share/post/twitter/4131126951?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131126951?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131126951?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131126951> Impact of best management practices on sustainable crop production and climate resilience in smallholder farming systems of South Asia <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131129195/2022/03/26/impact-of-best-management-practices-on-sustainable-crop-production-and-climate-resilience-in-smallholder-farming-systems-of-south-asia> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0308521X21002298> - March 26, 10:32 AM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131129195/2022/03/26/impact-of-best-management-practices-on-sustainable-crop-production-and-climate-resilience-in-smallholder-farming-systems-of-south-asia> Anantha, K.H., Garg, K.K., Barron, J., Dixit, S., Ventkataradha, A., Singh, R. & Whitbread, A.M. 2021.

Adoption of conservation measures helped enhance crop yields by 200–1000 kg/ha, reduced cost of cultivation and enhanced incomes by US$ 10–200/ha/year. They also enabled annual water saving in the range of 50 mm to 300 mm by either conserving residual soil moisture or saving irrigation water resulting in enhanced water productivity. Direct seeding rice and laser leveling were effective in water saving and reducing costs of production. Rain water harvesting was also a valuable practice. They conclude that the review revealed the ample scope of integrating in situ and ex situ interventions to build system-level resilience in smallholder farming systems. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131129195/2022/03/26/impact-of-best-management-practices-on-sustainable-crop-production-and-climate-resilience-in-smallholder-farming-systems-of-south-asia> <https://www.scoop.it/share/post/twitter/4131129195?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131129195?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131129195?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131129195> Soil health and nutrient density: preliminary comparison of regenerative and conventional farming. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131116200/2022/03/25/soil-health-and-nutrient-density-preliminary-comparison-of-regenerative-and-conventional-farming> From peerj.com <https://peerj.com/articles/12848/> - March 25, 6:22 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131116200/2022/03/25/soil-health-and-nutrient-density-preliminary-comparison-of-regenerative-and-conventional-farming> Montgomery, D.R., Bikle, A., Archuleta, R., Brown, P. & Jordan, J. 2022.

They used paired farms with these two practices across the USA and found soil health and crop nutrient density differences. Farms that used CA produced crops with higher SOM, soil health scores, and levels of nutrient density in the crops. Their data support the conclusion that regenerative agriculture (using CA) enhance the nutritional profiles of plant and animal foods. <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131116200/2022/03/25/soil-health-and-nutrient-density-preliminary-comparison-of-regenerative-and-conventional-farming> <https://www.scoop.it/share/post/twitter/4131116200?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131116200?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131116200?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131116200> Simulating no-tillage effects on crop yield and greenhouse gas emissions in Kentucky corn and soybean cropping systems: 1980–2018 <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131113501/2022/03/25/simulating-no-tillage-effects-on-crop-yield-and-greenhouse-gas-emissions-in-kentucky-corn-and-soybean-cropping-systems-1980-2018> From linkinghub.elsevier.com <https://linkinghub.elsevier.com/retrieve/pii/S0308521X21003085> - March 25, 1:17 PM <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131113501/2022/03/25/simulating-no-tillage-effects-on-crop-yield-and-greenhouse-gas-emissions-in-kentucky-corn-and-soybean-cropping-systems-1980-2018> Huang, Y., Tao, B., Yang, Y., Zhu, X., Yang, X., John, J.H. & Ren, W. 2022.

Tillage scenarios were CT and NT. Overall, NT reduced soil CO2 (−1.6% for corn and −4.53% for soybean) and N2O emissions (−10.5% for corn and −19.6% for soybean) compared to CT. However, corn and soybean yields with NT were not significantly different from those with CT. The summary does no indicate residue management that is important in helping with SOM accumulation and improved soil health. The authors conclude that the findings provide insights into how NT can enhance agroecosystem production stability and support climate change mitigation. . <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag/p/4131113501/2022/03/25/simulating-no-tillage-effects-on-crop-yield-and-greenhouse-gas-emissions-in-kentucky-corn-and-soybean-cropping-systems-1980-2018> <https://www.scoop.it/share/post/twitter/4131113501?forceAnonymous=1> <https://www.scoop.it/share/post/facebook/4131113501?forceAnonymous=1> <https://www.scoop.it/share/post/linkedin/4131113501?forceAnonymous=1> <https://www.scoop.it/topic/conservation-agriculture-by-conservation-ag?rescoopPostId=4131113501> ######################################################################## To unsubscribe from the CA-Cop-L list, click the following link: &*TICKET_URL(CA-Cop-L,SIGNOFF);
