insight:

This paper looks at CA adoption by smallholder farmers in SSA. They
indicate that CA has to be tailored to the agro-ecological and
socio-economic context of these farmers to achieve impact. But even then
adoption is not always done. This paper explores the reasons why farmers
choose or not choose to adopt in Kenya. They look at farmers attitude
towards CA, perception of social norms towards CA and their perceived
behavioral control (PBC) over practicing CA. They show strong evidence that
attitude and PBC are contributing to adoption.

insight:

This study looks at the accumulated impact of tillage systems (CT, MT and
NT) on weed emergence, and weed species density and diversity in Spain.
They also looked at two soil parameters, water stable aggregates and
particulate organic matter content on weeds. The highest weed densities
were found in MT and/or NT treatments several years after implementation of
treatments. They also resulted in increased seed density and species
diversity in the soil seed bank. They discuss why this happened and relate
it to less soil disturbance allowing seeds to remain dormant longer with
the improved water stable aggregates and organic matter content.

insight:

This multi-location study in Zimbabwe to determine the effect of 4 tillage
systems (CT, planting basins, rip-line and animal traction direct seeding
systems) on maize, soybean and cowpea yields and economic performance of CA
compared to CT. In the high and low rainfall conditions CT and CA gave
similar results for maize. In medium rainfall areas the three CA systems
gave better maize yields than CT. In the low and high rainfall areas, CT
and basins had the lowest maize production risk. Cowpea and soybena yield
was better in rip line and direct seeding compared to CT. Direct seeding
gave the highest net benefits in all three AE zones.

insight:

This study looked at strip intercropping, water harvesting through
conservation tillage and carbon sequestration through improved crop residue
management in China in a maize and wheat system. The results showed that
this integrated system increased soil moisture before, during and after
crops sown compared to conventional systems. This integrated system also
increased yields of wheat and maize and with straw mulching decreased
carbon emissions. The wheat/maize intercrops used more water but produced
42% more grain yields. They suggest this system can help alleviate food
security issues in degraded and water-short areas in China.

no-till fields (more than 20 years) in small grain production in southern
Brazil. The soils represented a range of textural and mineralogical
characteristics. The sampled NT and native vegetation soils to a depth of
one meter. The sites had recovered to 92-100% of the original SOC stocks.
The sites that represented medium cropping intensity recovered 80-85% of NV
stocks while sites representing high cropping intensity recovered 85-117%.
The lowest recovery of 61% had more soybens in the rotation.

insight:

This study assessed the effects on CT and NT as well as five NT cover crop
based cropping systems on yield scaled GHG emissions in two long term
experiments (18 and 19 years) in Brazil. They measured methane and nitrous
oxide fluxes. Annual rate of change of SOC was used as a proxy for net C02
flux. Cumulative annual emissions of the three GHG and the CO2 costs of
agricultural inputs and operations were taken in full account when
estimating the global warming potential (GWP). Under legume cover crops, NT
soil exhibited increased N2O emissions relative to CT soil (531 vs 217 kg
CO2eq ha−1 yr−1); however, emissions of this gas from NT soil were fully
offset by CO2 retention in soil organic matter (−2063 to −3940 kg CO2 ha−1
yr−1). Soil CH4 fluxes were very low with all management systems. The
legume cover crops increased maize yield and further reduced yield-scaled
GHG emissions.

insight:

They suggest that conventional tillage (CT) has resulted in deterioration
of soil quality in SSA through loss of SOM. This paper reviews the
literature on the impact of CA on soil quality especially soil physical,
chemical and biological properties. Also looks at the impact of CA on yield
and adoption. They conclude that soil quality and yield improvements are
possible with CA although there were some negative results in contrasting
environments. Yield under CA was more resilient than under CT where there
is seasonal rainfall variability. CA is relevant for South Africa although
more research on CA is needed for different AE zones and SE contexts,
especially for maize.

This paper looks at the feasibility of maize replacing rice in water short

(Permanent bed planting) and CT on 4 different rotations and studied SOC,
physical and biological properties. Their results suggest that CA based
crop management with diversified maize based rotations
(Maize-chickpea-sesbania & maize-wheat-mungbean) can be recommended as
sustainable intensification options in light textured soils in NW India and
similar agro-ecologies of South Asia

insight:

They used a socio-psychological model to understand factors affecting
adoption after 10 years of promotion in Mozambique. This research finds
evidence that CA, using no external inputs, is most attractive among the
very poor and that farmers are driven primarily by strong motivational
factors in the key areas of current contention, namely yield, labor, soil
quality and weeding time benefits. Farmers attitude was the strongest
predictor (80%) for such items as increased yields, reduction in labor,
improvement in soil quality and reduction in weeds. Members of FFS's or
participants of organizations have stronger positive attitudes.

insight:

Crop residues are essential for smallholder mixed cropping systems in SSA.
But they are also important for soils as returned residues. This household
survey looked at farmer allocation patterns of this important resource in
Ethiopia and Kenya. Results showed that farmers strongly favor allocation
of residues to livestock feeding but that allocation to soil increases
along the productivity gradient. This reduced feeding to livestock and
increased allocation to soil fertility is associated with smaller farm
sizes leading to reduced animal traction needs for tillage, increased
overall livestock productivity, increased use of inputs and a reduced
reliance on farm-based activities in overall livelihood strategies. This
could change if livestock intensification occurs in the future.

insight:

This interesting article compares synthetic herbicides with bio-herbicides
in integrated weed management systems. They contend bio-herbicides that
presently only represent less than 10% of all bio-pesticides are important
as substitutes for chemical herbicides especially in organic systems. This
review looked at the history, mode of action, efficacy and target weeds in
integrated weed management.

insight:

This study evaluated two resource-conserving agriculture systems in
Ethiopia after 7 years of inception. DER is a bed and furrow system where
the beds remain unplowed and 30% residue retained. TER is ploughed once at
planting, furrows made 1.5 m wide to create fresh broad beds and 30%
residue retained. TER and DER were compared with conventional tillage --
three tillage operations and complete removal of residues. Various soil
property measurements were made. Among the several assessed soil
properties, soil organic C (SOC), total soil N, available P, soil microbial
biomass C (SMBC), time of ponding, aggregate stability index (SI),
consistency index (CI), cone index, air capacity and macroporosity were
shown to increase significantly in soils subjected to DER+ planting system
compared to CT. On average, crop yields under DER+ and TER+ increased by 30
% and 16 %, respectively, as compared to CT. They suggest that some
incentives should be provided to facilitate larger adoption by farmers.
