*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at new assessment approaches that are needed to quantify
how conservation agriculture might contribute to soil health improvement
and soil organic C (SOC) sequestration. SOC sequestration was calculated as
the summation of SOC stock greater than the baseline condition at 30-cm
depth. Data from literature sources were mathematically fitted with this
new approach as a validation. Two on-farm surveys with different
agricultural management practices (5–40 yr) in the southeastern United
States yielded preliminary estimates of SOC sequestration. The
interquartile range of calculated SOC sequestration was 4.2–9.4 Mg C ha–1
for conventional-tillage cropland (n = 45 fields), 13.6–29.7 Mg C ha–1 for
no-tillage cropland (n = 97 fields), and 15.9–26.1 Mg C ha–1 for perennial
pasture (n = 29 fields).

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
Based on the findings from peer-reviewed literature, this review aims to
identify unsustainability issues and research gaps in the R–W system in
South Asia and propose possible solutions to mitigate those issues and
technological interventions to close the research gaps. Issues that the
review has identified are declining crop, water and land productivity,
deterioration of soil health, emissions of greenhouse gases due to
intensive tillage and residue burning, deepening of groundwater levels and
shift in weed flora and development of herbicidal resistance in
crops. Potential solutions or technological interventions to mitigate the
unsustainability issues include resource conservation technologies (RCTs)
such as rice residue management, reduced tillage, laser land leveling, soil
matric potential based irrigation scheduling, delayed rice transplanting,
cultivation on permanent raised beds, direct-seeded rice (DSR), mechanical
transplanting of rice and crop diversification with legumes. Sustainable
R–W production technologies with reduced water, energy and C footprints are
required for increased water and energy productivity and C sequestration
for the NW IGPs of South Asia.

https://doi.org/10.1016/j.indic.2021.100106
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This two-year field experiment was carried out to evaluate the impacts of
conservation tillage plus residue (CTS) on SOC accumulation, GHG emission
and water footprint (WF) in wheat cultivation of Bangladesh. NT and Minimum
tillage (MT) were compared with CT. SOC accumulation was higher in MT than
CT and highest in NT. GHG emissions were lowest in NT and highest in CT.
The lowest WF was for MT and highest for CT. They conclude that MT and NT
with crop residue retention are potential climate change mitigation and
adaptation  strategies suitable for production systems in Bangladesh.
However, comprehensive and integrated programs including extension, credit
and improved roads are needed to assist with adoption by farmers.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This a paper that looks at selection of suitable wheat genotypes for CA
that maintain productivity under drought conditions. The screened bread and
durum varieties under CT and CA for three crop seasons under rainfed
conditions in Iran. The wheat cultivars performed better in conventional
than conservation agriculture system with grain yield superiority varied
from 4 to 35%, depending on amount and distribution pattern of
precipitation over crop seasons. They concluded there was a positive
interaction of genotype and traits under the two tillage systems with some
traits (i.e., number of spike/m−2, SPAD reading, normalized difference
vegetative index (NDVI), days to heading, 1000-kernel weight and grain
filling duration)  effective in genotype adaptation to a particular system.
The wheat genotypes significantly interacted with different tillage
systems, implying the need for specific adaptation to tillage systems and
environments.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This field study evaluated the effects on cropping sequences and tillage
systems on SOC and N fractions. No-till (NT) and rotary tillage (RT) were
combined with four cropping sequences: wheat-soybean-wheat-maize (WSWM),
wheat-maize-wheat-soybean (WMWS), wheat-soybean-wheat-soybean (WS) and
wheat-maize-wheat-maize (WM). Tillage systems affected SOC and N in topsoil
rather than deeper, but cropping sequences in the whole sampling depth
(0-50cm). NT had significantly higher SOC concentrations than RT at the
0–10- (17% higher) and 20–30-cm (19% higher) soil layers. NT had 17%
significantly higher N contents than RT at the 0–10-cm soil layer, but RT
had 21% significantly higher N accumulation at the 10–20-cm soil layer. The
particulate organic carbon (POC) was highest in WM and lowest in WS
cropping sequence at 0–10-cm soil depth. Particulate organic nitrogen (PON)
was significantly higher in soybean-included cropping sequences only at
0–10-cm soil depth. Overall, their findings suggested that NT especially
with soybean could be a suitable practice to sequester SOC and N in the
North China Plain.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study looks at the data from a long-term trial in Eastern India with 4
treatments: Traditional rice-wheat (TA), Full CA (fCA), and two partial
CA's, pCA1 and pCA2 that differ in crop establishment methods, cropping
system and crop residue management. Soil health parameters were measured in
the 11th year of the experiment. The results revealed a beneficial effect
of CA and 46 and 40% increase in SOC concentration and stock, respectively,
under fCA over TA in the 0–7.5-cm soil layer. The effect of partial CA
(pCA1 and pCA2) was variable, but an increasing trend was always observed
under pCA compared to TA. The yield of rice in CA was comparable to or
higher than in TA, whereas the system rice equivalent yield was always
higher (38–53%) under CA than under the conventional practices. They
conclude that CA can be promoted for sustainability of a rice–wheat system
due to higher productivity (38–53%).

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
Burning of rice residues in the rice-wheat system especially in NW India is
causing severe air pollution. Since the use of new locally produced seed
drills that can plant into loose straw provides one solution to this
problem, this paper was included. The objectives of this paper are to
estimate the crop residue burning and emissions from crop residue burning,
to recommend interventions in crop residue management and to propose a crop
residue management-bioeconomy model incorporating strategies to sustainably
manage the crop residues through interventions that enable waste
valorization, food and nutritional security, farmers’ livelihood and
sustainable agricultural production system. This paper provides some
alternative ways to eliminate residue burning. that can provide lessons for
other regions with similar problems.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper was chosen because in countries like Bangladesh, 2-wheel
tractors are more appropriate for the small land holdings and strip-tillage
works well. This article looks at rotary blade design when there is
residue. They looked at 4 types of rotary blade with different tip angles
but constant rotary speed for wheat and maize in Bangladesh. The research
looked at the quality of strip; width of furrow, depth of seed placement
but also germination and percent straw cut. Soil cutting depth of strips
and seed placement depth was consistent all over the field by the modified
blades during wheat and maize sowing. The 15° tip angle blades into 15 cm
anchored rice residue (RH15) showed excellent seed germination rate of 96%
for wheat and 79% for maize.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper applied two independent soil health assessment approaches to
evaluate the impacts of 40-yr conservation tillage (CST) and additional
4-yr cover cropping on a range of soil health indicators and the overall
soil health in typical southeastern Coastal Plain soils of the USA. The
Soil Management Assessment Framework (SMAF) and Cornell's Comprehensive
Assessment of Soil Health (CASH) were used to calculate soil health
indices. When compared to conventional tillage, 40-yr CST increased active
carbon (C) from 301 to 420 mg kg–1 and organic nitrogen (N) mineralization
potentials from 0.78 to 0.91 mg kg–1 d–1, but it reduced soil electrical
conductivity from 133 to 101 μs cm–1. No difference in soil aggregate
stability, total C, extractable phosphorous and potassium, microbial
biomass C, respiration, and glucosidase activities were observed between
the two tillage treatments. Increasing organic inputs along with CST is
seemingly the optimal management option.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study looked at three climate smart technologies (CSA) experimented by
farmers in Malawi in terms of soil quality and maize yields and compared to
CFS. The three technologies were conservation agriculture (CA),
maize–pigeonpea (Maize-PP) intercrops and a local organic and inorganic
soil amendment known as Mbeya fertilization (Mbeya-fert), from 2018 to
2019. Particulate organic matter, soil organic carbon (SOC), N, P, K, Ca
and Mg all significantly improved while bulk densities were lowered under
the three CSA systems compared to conventional farmer systems (CFS). CA and
Mbeya-fert improved maize yields by 51 and 19%, respectively, compared to
conventional farmer practices. They concluded that employing these CSA
technologies could enable farmers to be more resilient, productive and
adapt better to climate change shocks leading to improved food security and
livelihoods.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study assessed the changes in soil quality indicators and their
influence on crop productivity through crop residue (CR) retention and
potassium (K) management under a zero tillage maize-wheat cropping system
in India. The treatments consisted of 4 residue levels and 5 K levels. Both
residue and K increased root-associated parameters.  Changes in soil
aggregate stability, available nutrient status, soil organic carbon (SOC)
mass, SOC stock, microbial activities, plant nutrient uptake, and biomass
yield were found significant with residue and K under zero-tillage.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This review paper looked at the smart solutions that enabled the spread of
CA in the Mediterranean Basin by looking at the evolution of strategies and
the machines used to perform CA in the last 30 years. They also looked at
the effects of their adoption on the productivity of herbaceous and
horticultural crops, weed control, and economic feasibility compared to
conventional systems using soil inversion. They conclude that farmers play
a crucial role in the adoption of smart solutions for increasing the
sustainability and productivity of crops. However, farmers have barriers
like inadequate policies, subsidies, direct farm payments, available
machinery and suitable weed control practices. Appropriate incentives and
governance practices are needed to guide farmers.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper was given at the 1st International conference on Sustainable
Land Management in Indonesia. This paper looks at the impact of CA in a
semi-arid area of Indonesia. All the farmers in this project say that CA
increased maize productivity and some farmers were even able to plant two
maize crops with good yield in a drought year. Integrating forage into CA
based farming also enabled farmers to provide enough feed 1-2 cattle per
household. In this area basins were dug and then CA used. Labor was an
issue but I suggest they make these basins permanent to lessen labor in the
second crop/year. The residue mulch is also needed for animal feed. Similar
to other dryland areas.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper provides information to society and decision-makers about the
effectiveness of of conservation agriculture (CA) principles with zero
tillage (ZT/CA) and integrated crop–livestock–forest (iCLF-CA) systems as
central policies to mitigate soil erosion, the main agent of land
degradation and productivity loss in Brazil. The annual potential for soil
erosion with intensive conventional tillage and monocropping, considering
land use and cover in 2017, is 3.0 billion tons. The economic impact, based
only on replacement of nutrient losses, is estimated to be 15.7 billion US$
yr−1. The annual economic impact of the adoption of CA principles by
controlling soil erosion was estimated at 1.5 billion US$ for ZT/CA in 2017
and 0.5 billion US$ for iCLF-CA in 2015. They conclude that the positive
impacts of the adoption of CA principles in Brazil are the result of the
determination of farmers, among many actors, and of the effectiveness of
government plans and policies.

https://doi.org/10.1111/agec.12640
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looked at the economic impacts in 1901 sampled wheat fields in
Morocco with different tillage intensities. Results from an endogenous
switching regression model showed that fields that were not tilled gave
298.6 kg/ha (23%) higher yields, US$89/ha (27%) more income and more stable
yields than those tilled once or more. Fields that were not tilled also had
87% lower yield variance with 100% and 65.6% less risk of giving yield
levels below 500 and 1000 kg/ha, respectively. Labor saving from avoiding
tillage under ZT was undermined by higher labor needed for weeding.
However, if this constraint can be removed reduced or zero-tillage can
improve the economic and biophysical viability of dryland agriculture in
this country.
