insight:

This study measured SOC in the top 15cm over 12 years in two agronomic
long-term trials in Western Kenya. These trials include various levels –
from absence to full adoption – of two widely promoted sustainable
agricultural management practices: Integrated Soil Fertility Management
(ISFM; i.e. improved varieties, mineral fertilizer and organic
matter/manure incorporation) and Conservation Agriculture (CA; improved
varieties, mineral fertilizer, zero-tillage and crop residues retention).
None of the tested ISFM and CA treatments turned out successful in
sequestering SOC long-term. Adopting zero-tillage and residue retention
alone (as part of CA) could avoid SOC losses of on average 0.13tCha−1 yr−1,
while this was 0.26tCha−1 yr−1 in response to mere inclusion of manure as
part of ISFM.

insight:

This study for the sub-tropics and tropics, used meta-regression, in
combination with global soil and climate datasets, to test four hypotheses:
(1) that relative yield performance of conservation agriculture improves
with increasing drought and temperature stress; (2) that the effects of
moisture and temperature stress exposure interact; (3) that the effects of
moisture and temperature stress are modified by soil texture; and (4) that
crop diversification, fertilizer application rate, or the time since
no-till implementation will enhance conservation agriculture performance
under climate stress. The results show through meta-regression that
conservation agriculture enhances the adaptive capacity of maize production
in sub-Saharan Africa under drought and/or heat stress. However, in very
wet seasons and on clay-rich soils, conservation agriculture yields less
compared to conventional practices.

insight:

This study evaluated SOC sequestration for several long-term rainfed
cropping systems for CA and conservation tillage (CT) in Cambodia using the
EPIC model. In all CA treatments, forage or legume cover crops were prior
planted and intercropped with the primary crops to maintain full soil
cover. Crop residue was found to highly influence SOC sequestration.
Sediment loss in the CT treatments was found to be four times greater than
CA treatments due to the CT tillage effects. The 20-year future
simulations, using historical weather and automatically generated by EPIC,
showed a decrease trend in SOC stocks in all CT treatments and an increase
trend in most CA treatments. The CA treatments in combination with the
maize rotation were demonstrated to be more efficient to manage SOC
sequestration over CA with one continuous primary crop.

insight:

This paper looks at whether tillage should be an evaluation factor in
breeding programs. 26 bread and durum wheat genotypes created from
1964-2009 were tested for yield and agronomic performance over 6 years in
Mexico using conventional (CT) tillage and permanent raised beds with full
and reduced irrigation. Breeding progress was achieved irrespective of
agronomic treatment. Tillage influenced plant growth and number of grains
per m2 in both wheat types. In bread wheat, genotype by tillage interaction
was significant for yield, test weight, and growth parameters. However, no
cross-over effects were detected and rank changes were small. In durum
wheat, genotype by tillage interaction was only significant for plant
growth. The results do not indicate the need for separate breeding
programs. However, the question of a need for selection under zero tillage
to increase breeding progress is yet to be answered.

insight:

This is another paper that looks at inclusion of maize instead of rice in
the RW systems of NW India. This paper also looks at the impacts of CA
management on MW systems in a three year experiment to look at crop and
water productivity, profitability and soil organic carbon accumulation.
Results showed that the plots under permanent broad bed with residue
(PBB+R) and without residue (PBB) resulted in 29 and 26% higher maize grain
yield, respectively than conventional tillage (CT) (2.6tha−1), but wheat
grain yields were comparable in all the treatments in first year. The PBB+R
was superior to other practices. This also saves water through higher
water-use efficiency, and lead to accumulation of more carbon in soil with
higher sequestration potential, besides giving sustainable production of
maize and wheat over the years. It also gave higher net returns compared to
CT.

insight:

Reduced tillage can lead to yield reduction and weed problems, especially
in the early stages of adoption. This paper looks at cover crops as a way
to control weeds and sustain yields. 8 cover crop treatments were used in a
long term experiment in Switzerland. Cover crops were cultivated for a
short 2 months between two winter wheat crops. In all treatments the cover
crops suppressed weed biomass compared to no cover crops. Wheat yield was
higher in the minimum tillage treatment than the plough treatment. Results
demonstrated that the presence of a well-developed cover crop, even for
only two months, sustains wheat yield in a no till treatment. It impacts
also soil fertility and nutrient cycling.

insight:

This study looks at whether CA can influence land degradation and soil
erosion challenges in Southern Africa. Despite the many potential benefits
of CA, however, adoption remains low. Yet relatively little is known about
the decision making process in choosing to adopt CA or any of its
constituent practices. Unlike what is implicitly assumed when these
packages of practices are introduced, farmers view adoption of CA as a
series of separate decisions, rather than a single decision. They find
strong evidence of interrelated decisions, particularly among mulching crop
residues and practicing zero tillage, suggesting that mulching residues and
intercropping or rotating with legumes introduces a multiplier effect on
the adoption of zero tillage.

insight:

Low input rice-maize systems in the hills of Madagascar suffer from erratic
rainfall, poor soils, soil erosion and infestation with Striga. They looked
at CA (ZT plus permanent soil cover by intercropping of legumes and residue
mulches) to remedy these problems. In all CA practices S. asiatica
infection was significantly reduced. Best results were obtained with
Stylosanthes guianensis (CAST). This species also suppressed ordinary weeds
much better than other cover crops. With CAST, average parasite emergence
was delayed by 7.5 days (in rice) and 6.3 days (in maize) and infection
levels were reduced by 79% (in rice) and 92% (in maize) compared to the
conventional farmer practice (CONV). They did conclude, though, that even
the combination of zero-tillage, crop residue mulching, cover crops and
resistant rice varieties does not entirely prevent S. asiatica parasitism
and seed bank increase. Additional measures, targeted to escaping weeds,
would be required for fully effective and long-term control.

insight:

This paper looks at the effect of shifted planting dates of wheat on
mitigating the potential increase in food insecurity resulting from
temperature rise due to climate change. A diverse set of twenty-one
genotypes was evaluated over three years (2012–2014) under ten levels of
crop management practices (ten different dates of sowing: D01-D10) across
three agro-ecological regions (BR (Bihar), MP (Madhya Prdesh) and PB
(Punjab)) of India in replicated trials. Results revealed that the impact
of shifted sowing dates on yield stability was unevenly spread across
management practices. Across locations, the genotype ‘CSW 18’ (G03), ‘DPW
621-50’ (G05), and ‘BAZ’ (G01) were the best performers and highly stable
in early, normal and later sowing dates, respectively. This would be
important for ZT systems where earlier planting is more feasible than with
CT.

insight:

This paper uses soil organic carbon and soil enzymes as indicators of short
term impacts of soil management. It looks at the impact of tillage and crop
rotations with diverse residue inputs on these two indicators in rice-,
soybean-, and cassava-based cropping systems in Cambodia. After 5 years
experiment period, greater hot-water extractable organic C (HWEO-C) stocks
of 61%, 55% and 53%, and permanganate oxidizable C (POX-C) stocks of 23%,
21% and 32% were attributed to NT than those in CT soils under RcCS, SbCS
and CsCS, respectively, at 0–5 cm soil layer. They conclude that short-term
NT crop rotations with permanent soil cover significantly increased the
storage of HWEO-C and POX-C and enhanced β-glucosidase and arylsulfatase
activities at the surface soil layer as a result of higher biomass-C input
and the absence of soil disturbance.

insight:

Issues of water deficits and low water productivity of rice-wheat in
northwest India led to research on replacing rice with less water requiring
maize. It also looked at CA-based management (tillage, residue (R) and
integration of mungbean (MB)), precision water management (PI) on crop and
water productivity and economics in RW and MW systems. It also looked at
fresh beds versus permanent beds. The results show that CA based
sustainable intensification of MW systems (PBMW + MB + R + PI) is a better
alternative than the RW system (ZTRW + MB + R + PI) as it provides
opportunities for saving 79% of precious water, enhancing crop and water
productivity by 12 and 145%, respectively along with high (34%) economic
benefits.

insight:

This paper looks at the adoption of CA -- partial and complete - in South
Asia (India, Nepal and Bangladesh). It looks at the factors affecting
adoption and did-adoption with particular reference to the role of spouses
and social networks. They find social networks have a significant positive
effect on adoption but negative for abandonment. Spouses also have a
positive effect on adoption. Farmers that had seen partial CA in action
were more likely to adopt than if they just heard from neighbors.
