*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This is the first selected paper for 2022 that uses meta-analytic and
mete-regression to assess CA long-term experiments that also have CT
practices in Southern Africa. They assessed how different
agro-environmental yield response moderators such as type of crop
diversification and amount of rainfall affect maize yield responses,
especially for smallholder farmers. Results show that long-term trends in
yield performance are a result of many factors; the greatest yield gains at
each location ranged between + 34% and + 117%; the greatest yields were
found in direct seeded rotation systems; rotations involving legumes were
more responsive than any practice without diversification; CA systems gains
increase with time of practice as compared to CP and these responses are
more pronounced under low to moderate rainfall, and in well drained soils.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looked at SOC recovery from long term CA on-farm fields in
Brazil. The study evaluated two systems -  (a) a comparison of SOC stocks
to a 1-m depth in long-term CA at the farm scale (>20 years) with paired
native vegetation and nearest available long-term research experiments (>30
years) in Southern Brazil; (b) explore the role of oilseed radish (Raphanus
sativus L.) as a cover crop to enhance SOC accumulation. For the farm level
CA systems, average SOC recovery was 92% (0–0.30 m) and 97% (0–1.0 m) in
the soil profile relative to native vegetation. The main characteristics
for SOC recovery (0–1.0 m) were high inputs of plant biomass, lack of soil
disturbance, and diversification with oilseed radish cover crop.

https://doi.org/10.3390/w13121645
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper explores the irrigation potential from surface and groundwater
sources under different water application and farming systems in Ethiopia.
Two tillage systems were evaluated -- CA and CT. Two irrigation systems -
drip and overhead. They looked at various irrigated vegetable crops. Their
results showed that CA plus drip was best in terms of irrigable land from
groundwater recharge. In comparison, the CT system with overhead irrigation
was the worst treatment. They conclude that decision makers must consider
the introduction of feasible and affordable technologies to make use of
groundwater and direct runoff, to maximize the potential of dry season
production through efficient and appropriate CA and water management
practices.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper from ICARDA looks at the performance of various crop genotypes
under CA and look at the tillage by Genotype interaction and effects on
yield of barley, chickpea, lentil, and wheat. Thirteen elite genotypes for
each crop were planted under both CA and CT systems. They conclude that
varieties with wider adaptability to drought, higher yield stability, and
adoption of CA practices may be more efficient than developing breeding
programs for each type of tillage system.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at the issue of Glyphosate resistant weeds in the soybean
crop grown with CA in North America. The rise of Glyphosate resistant weeds
in this crop has led to reductions in use of CA in soybeans.They estimate
reduced-form and structural probit models of tillage choice, using a large
panel of field-level soybean management decisions from across the United
States spanning 1998–2016. The first emergence of glyphosate-resistant weed
species did not effect tillage practices, though by the time that eight
glyphosate-resistant weed species were identified, conservation tillage and
no-till use fell by 3.9% and 7.6%, respectively. They estimate an economic
value of the proliferation of Glyphosate resistant weeds in soybeans in USA.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at the issues of weeds and nutrient immobilization in CA
systems in India in the maize-wheat system. For weed control they looked at
using Sesbania brown manuring followed by post-emergent herbicides in maize
and a herbicide tank mix in the following wheat that gave minimal weed
infestation and the highest maize and wheat yields. For nitrogen the best
treatment was half applied basal and the rest as guided by an Optical crop
sensor, resulted in saving 56 and 59 kg N ha−1 in the maize–wheat system,
respectively, over 100% N application as farmers’ fertilizer practice.
There was also a significant interactive effect of weed management and
N-use on economic maize and wheat yields.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This chapter 11 in the book listed above is devoted to CA in rice-wheat
areas of South Asia. This geographic area is challenged to feed almost 2.5
billion people while the resource base is being degraded and climate change
is causing significant problems. CA is being promoted as a management
system to combat some of the challenges arising from previous intensive
tillage systems. Much work has been done on the rice-wheat systems with CA
management. Recently, these practices have also been applied to other crops
and systems in South Asia with encouraging results. This chapter describes
some of these successes.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This 13-year study in India looked at soil properties and the fate of
Pendimethalin herbicide in a CA and intensively tillage managed system. Two
cropping systems were mungbean-wheat and sorghum-wheat. There were three
tillage treatments -- ZT+residue in both seasons; CT in summer + ZT+residue
in winter; and CT in both seasons. The adoption of ZT-ZT system resulted in
a 24% increase in infiltration rate, 13% greater moisture retention and 69%
higher organic carbon content in surface (0-0.05 m) soil over CT-CT. Under
the CT-ZT treatment, only a small change in the above soil properties was
observed, which indicated that the benefits associated with CA was lost
with tillage in the subsequent season. ZT-ZT caused more herbicide leaching
into the sub-surface soil.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at barley and maize in Mexico's major growing area for
barley where barley is irrigated followed by rainfed maize. Groundlevel
water levels are declining in this area and water saving technologies are
needed in this area. This study looked at water use and grain yields with
CT and CA with furrow and drip irrigation in 3 year experiment and in
adjacent farmer fields. Results show water use reductions differed strongly
between years, depending on weather. The water saving through conservation
agriculture in farmers' fields was similar to the water saving in the
controlled experiment with about 17%. Farmer's fields conservation
agriculture also reduced greenhouse gas emissions by 192 kg CO2/ha and
improved soil health.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at appropriate equipment for 2-wheel tractors in
Bangladesh that allow timely field operations. The specifically look at the
design of the blade and furrow openers for strip tillage under different
soil types and environments. Compared to shoe-type openers, better seeding
depth, uniformity and higher degree of seed coverage were recorded with use
of the inverted-T furrow opener with a 65° rake angle. This resulted in
better seed coverage in the furrow, a higher emergence rate index, and the
highest emergence percentage of maize and mung bean.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper used an integrated framework that included bioeconomic
simulation, risk analysis, adoption theory and impact assessment to look at
CA components and growing a new crop or variety performed over a 10-year
period on farms in Central Mexico. They found significant differences in
profit, net value, downside risk, and risk-aversion cost between
double-component scenarios (and improved CA to a lesser extent) and all
other scenarios, which suggested that disaggregating CA into smaller
component packages could increase farmer adoption in risky contexts. The
study highlighted the need for employing a range of research tools to
understand the relative value of agricultural innovations and to identify
and reduce trade-offs and uncertainty in farming systems.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This is another interesting article of surface dwelling beetles that are
important for biological pest control and organic matter decomposition. It
looks at the beetle community responses to 6-years of tillage, crop residue
use, rotation and soil fertility amendments. Reduced tillage increased
beetle abundance  compared to inversion tillage. Crop residue also
increased the incidence of some beetle species by 2-3 times. Another beetle
increased by 628.6% in high fertilizer compared to manure + 60 kg N ha−1,
manure + low fertilizer and the control. They conclude that reduced
tillage, retention of crop residues on the soil surface and application of
manure increase surface-dwelling beetle abundance and diversity.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This is an interesting article from India on the impact of CA on insect
pests and their natural enemies in wheat in the rice-wheat system of the
Western Indo-Gangetic Plains. Major insect pests (foliar aphids, root
aphids, termites, and pink stem borer) and their natural enemies in wheat
managed under three tillage practices, i.e., zero-till (ZT), reduced
tillage (RT), and conventional tillage (CT) with (protected) and without
(unprotected) insecticide protection scenarios, was investigated. Foliar
aphids and termites were lowest in the ZT-protected treatments and highest
in the CT-unprotected system. Root aphids were highest in the reduced
tillage-unprotected system. More fine-tuning of insect-pest management
tactics based on these relations would enhance the success of CA systems.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study on the rice-wheat system of the Indo-gangetic plains of South
Asia addresses the negative issues of the tillage, water, energy and
capital intensive practices of this traditional system. There is also a
major issue of crop residue burning, especially during rice harvest. 6
management scenarios are used consisting of business as usual (BAU) as the
check compared with various combinations of ZT and RT; residue use;
recommended dose of fertilizer (RDF); use of the Greenseeker tool as a
nutrient-expert tool. The latter listed as "Climate Smart Agricultural
Practices (CSAP). They conclude that  CSAPs can cope better with climatic
extremes than BAU and should be further promoted.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at the gender implications of a change in weed management
from tillage to herbicide with CA in South Asia. This was done by surveys
with both spouses during crop establishment using 24 households who have
adopted NT systems in the Eastern Gangetic Plains of South Asia.
Comparisons were made pre- and post-tillage uptake. The found that the
switch to NT provided substantial time-savings and did not increase the
burden on women. ZT use did not reinforce or deepen existing inequalities
within households.
