insight:

A paper that reviews the experiences with CA in SSA over the past two
decades. First it outlines the context and challenges for CA in SSA
followed by the main issues crucial for successful design and
implementation of CA programs. It is based on available literature and
author experiences in the region. It ends with key lessons and strategic
recommendations.

insight:

This paper looked at CA on GHG emissions and yield in a dry climate of 3
long term (17-18year) tillage systems: conventional (CT), minimal (MT) and
no-tillage (NT). This study suggests that NT and crop rotation can be
recommended as good agricultural practices in order to establish an optimal
balance between GHGs fluxes, GWP, yield-scaled N2O emissions and N
surpluses.

insight:

This study aimed to determine if aspects of CA, namely tillage and mulching
with manure and fertiliser application, improved soil mineral N release,
plant N uptake and maize yields in cropping systems on poor soils in
semi-arid Matobo, Zimbabwe. Tillage (animal-drawn ploughing and ripping)
was the main plot treatment and residue application was the sub plot
treatment with two levels (100% residues removed or retained after
harvest). There were 5 fertility amendments. The CA principles of minimum
soil disturbance and maintenance of a permanent mulch cover resulted in
reduced soil mineral N availability for crop uptake and poor maize yields.
Nutrient inputs through mineral fertilisers and manure are key to ensuring
production in such infertile, sandy soils which predominate in semi-arid
regions of southern Africa.

insight:

This study focuses on conservation agriculture (CA) technology adoption
dynamics among a small group of farmers who can be considered increasingly
knowledgeable, as they have hosted CA demonstration-trials for at least 7
years. It was found that closing knowledge gaps on CA did not close YGs and
that CA adoption was partial. In the three areas, farmers’ interest in CA-
based increasing of yields was limited, as circumstances drove them to
embark on extensification rather than a land use intensification pathway.

insight:

This study was designed to better understand runoff and soil erosion rates
in Brazil, and review the plot-scale studies that have been conducted
across the country. They found mean values of observed annual soil loss
ranging from 0.1 t ha y− 1 (grassland and pasture in the southern region)
to as great as 136.0 t ha y− 1 (tilled fallow plots, without plant cover,
in the northeastern region). They conclude that In order to reduce the
variability of the observed data, develop models, and support decisions, it
is important to increase the monitoring period of the experimental sites.

This paper highlights issues in the neglected rainfed eco-systems of
Central India tribal areas. This area has degraded soils and unreliable
weather patterns. They looked at conventional tillage with 4 CA treatments.
Results showed that reduced tillage combined with maize-cowpea
intercropping followed by mustard residue retention had higher system
productivity and net benefits, 200 and 230%, respectively. The soil quality
index was also highest under this treatment. 35% of the farmers preferred
this treatment compared to 14% for the farmer practice. They used a
trans-disciplinary approach.

insight:

This was a 12 year study to evaluate soil conservation from southern
Alberta, Canada. The CONS management was a suite of practices that included
addition of cattle manure compost, reduced tillage, diverse crop rotations
and use of cover crops that CONV management did not have. Soil microbial
biomass was measured in bulk soil and the wheat rhizosphere in the last 2
years. Total soil microbial biomass, and that of its components (fungi and
bacteria), was significantly greater under CONS management than under CONV
management. They conclude CONS practices will enhance biological processes
including nutrient cycling and biological pest control.

insight:

The paper suggests that recent studies have shown that previous estimates
of SOC storage under NT seem to be overestimated due to shallow sampling
and improper SOC accounting. They used meta-analysis of 95 comparisons of
CT and NT from 57 sites covering various cropping systems in China. The
results revealed that compared to CT, adopting NT led to SOC accumulation
in the upper 20 cm layer and SOC depletion in the 30–40 cm layer. Further
analysis suggested that the effect of NT on SOC storage was significant
with residue retained‎, double cropping systems, and in the coarse textured
soils. We conclude that although NT was an effective agronomy option for
soil conservation in China, the potential for mitigation climate change
through increased SOC sequestration by NT should not be amplified.

insight:

The objective of this study was to determine soil physical properties under
R and IR zones under NT soybean. There were significant differences in all
soil physical properties among R and IR zones when measured 15 days after
sowing. At 52 and 115 days pore continuity did not differ, but BD, FC, air
permeability and total porosity did. Soil resilience was evident even over
a short term, improving soil physical quality at IR position. The large
contrast in soil physical parameters between R and IR positions was
observed right after sowing, gradually decreasing over time and no longer
being detectable by the end of the growing season.
