*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This long-term experiment (14 years) combined fertilization rate (no, low
and high N fertilizer, N0, N1 and N2), straw additions (no, low and high
addition, S0, S1 and S2) with conservation tillage (no-tillage, NT) in the
North China Plain. 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://doi.org/10.1016/j.geodrs.2021.e00463
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper assessed the soil microbiota in a long-term, 42 year tillage and
fertilization experiment under continuous maize in Romania. 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://doi.org/10.1016/j.jeem.2021.102556
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper aims to provide evidence that payments for ecosystem services
encourage the adoption of conservation practices like CA. 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.

This paper reports on the eukaryotic community diversity in small  (sM) and
occluded micro-aggregates (mM) following 23 years of reduced versus
conventional tillage and 0 and 200 kg of nitrogen in a wheat soybean
rotation. They found a different eukaryote diversity response to management
intensification across soil aggregates and soil depths; (ii) a conserved
core community composition of eukaryotes across CA treatments and
aggregates at surface and subsurface layers; (iii) a different effect of
tillage on eukaryotic community structure in sM and mM along the soil
profile according to N availability; (iv) a positive association of
protists, and fungi with the amount of sM and mM, and their SOC content;
(v) a stronger complexity of within- and cross-domain networks (eukaryotes
and eukaryotes-prokaryotes) in mM than in sM at surface layer.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This is a valuable paper describing aspects of the use of service providers
to enable smallholder farmers to adopt new technologies and scale up
adoption. It uses direct seeded rice (DSR) in Eastern India as a case
study. This study explores with zero tillage drill owners the decision
processes they apply in deciding how to use their zero tillage drills.
Respondents highlight a complex web of interrelated considerations that
highlight the additional complexities of DSR as compared to existing
practices. They conclude that the methods they used would be useful for
exploring other other farmer decision making.

a maize-maize-mustard rotation to determine if it would enhance yield,
energy-use efficiency, water productivity while reducing GHG emissions.
No-till-live mulch had 36.4% less energy requirement, and 2.4 times more
energy productivity than conventional tillage. CT had the highest net
CO2-eq emission while NT-live mulch had the lowest.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at two tillage treatments, NT and CT, on 4 crop covers;
monocrop maize, monocrop soybean, rotated maize, and intercrop of maize and
soybean on infiltration of water. Tillage and crop cover both affected
infiltration with NT infiltration better than CT. The authors conclude that
NT with greater cover improves infiltration and soil water storage.

This study explores the farmers' experiences and drivers for adoption of CA
in the Eastern Gangetic Plains of South Asia through57 qualitative and
semi-structured interviews of farmers presently using CA practices across 6
locations. To overcome various hurdles for adoption responders adopted
various strategies to improve adoption. Some farmers assumed the role of
educator and shared their knowledge with others. They highlighted the need
for stover retention,  self investment, and communal purchase of equipment.
The farmers listed a number of benefits from adopting CA including improved
socio-economic conditions, respect in the community and more free time to
do other things. The farmers also improved their links with agricultural
institutions in the country.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This field experiment evaluated energy budgeting, carbon footprints (CF)
and greenhouse gas (GHG) emissions from rice-wheat cropping systems under
long-term tillage and residue management practices in NW India. 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

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looked at GHG emissions in a controlled traffic situation,
adopted to avoid soil compaction effects on the crops, and with regulated
deficit irrigation (RDI), adopted to conserve water in an irrigated
maize-cropping and fallow periods on a long-term tillage, 2-year experiment
in Spain. 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.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This article looks at permanent bed planting (PBP) to improve soil quality,
soil moisture conservation and stabilize yields of wheat in furrow
irrigated systems in Mexico. 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.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This article quantifies the effect of Best Management Practices (BMPs) on
crop productivity, income, water saving and water balance components and
identifies gaps for future research by reviewing 108 published studies from
South Asia. 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.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper by a renowned soil scientist looks at regenerative agriculture
(for 5-10 years) compared to conventional Synthetic fertilizer, and
herbicide). 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://doi.org/10.1016/j.agsy.2021.103355
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This long term no-till article in Kentucky used a agroecosystem model along
with environmental datasets to quantify effects of NT on yield and GHG
emissions in corn-soybean cropping systems. 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.  .
