*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
Increasing climate variability is affecting  smallholder farmers in
southern Africa. This study looks at Conservation Agriculture (CA) as a way
to improve the resilience of farming systems against the adversities of
climate, specifically moisture stress.CA and CT practices are assessed over
a 14 year trial period on soil moisture and infiltration rates in Zambia.
Soil chemical properties were also evaluated for these two tillage systems.
Results showed significant differences in average soil moisture in the
first 60 cm among the cropping systems in different years with the basins
plus mulching system having highest moisture content in most of the years.
Water infiltration rates were highest and averaged 48.5 mm h−1 in the
CA-based systems and the lowest in CT which averaged 12.6 mm h−1. Soil
chemical properties did not differ across tillage systems. The increased
infiltration and available moisture in CA systems can buffer the effects of
climate variability and provide greater resilience.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study was evaluated the effect of conservation tillage practices in a
maize-wheat cropping system on near-saturated soil hydraulic properties and
pore characteristics.There were three tillage treatments - CT, Minimum
Tillage (MT) and ZT - were evaluated after 7 years of each tillage
treatment . Results revealed significantly (p < 0.05) higher values of ks,
k(h), α, and Ɛ in ZT as compared with CT. MT had intermediate
values. Overall, zero-tillage based agriculture system was found to improve
near-saturated soil hydraulic properties.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study aimed to quantify the effect of tillage, crop rotation and crop
residue management on aggregate stability, binding agents and the resulting
aggregate microstructure in a sweet sorghum-based cropping system in a low
organic carbon soil. Two tillage levels; no-till (NT) and conventional
tillage (CT), two crop rotations, i.e., sweet sorghum-grazing vetch-sweet
sorghum (S-V-S) and sweet sorghum-fallow-sweet sorghum (S-F-S) and three
crop residue retention levels, i.e., 0%, 15 % and 30 % were tested. The
study showed that tillage is the main factor that influences soil
aggregation followed by residue management. The study also demonstrated
that aggregate stability is linked to aggregate microstructure and regular
pores are dominated in degraded soils with low SOC.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This 16 year long term study in Hungary looked at the effect of
conservation tillage (CT) on run-off, soil loss and soil in large plots and
compared with ploughing tillage (PT). By the end of the study period,
significantly higher water-stable aggregates (PT: 20.0 %, CT: 30.4 %),
higher soil organic matter (PT: 1.4 %, CT: 1.9 %), greater earthworm
abundance (4.9 times that in PT plots) was recorded on the CT plots. The
difference between PT and CT was significant for mean annual soil erosion,
with values of 2.8 t ha−1 and 0.2 t ha-1, respectively. They conclude that
the use of CT enabled the maintenance of a major fraction of precipitation
on arable land, and consequently, soil loss remained an order of magnitude
lower than its tolerable value.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
In this paper, a process-based model, Denitrification-Decomposition (DNDC),
was validated on midterm (9 years) and employed depending on the local
climate, soil and management conditions, to assess the impacts of
alternative management practices on SOC stock under two tillage systems, in
a semi-arid region of Morocco. Modeled results pointed out that, under
no-tillage practice (NT), the SOC content increased by 30% compared to
conventional tillage (CT). During the simulated period (9 years), the SOC
sequestration potential (CSP) has been greatly improved with increased crop
residue rate and application of farmyard manure (FY-manure). They conclude
that an increase in crop residue rate returned at surface after harvest and
application of organic fertilizer, especially under NT practice, can
substantially improve SOC stock in a semi-arid region.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This Brazilian study looked at water retention in relation to soil physical
and chemical properties on Cambisols with different land uses in a
semi-arid region of Brazil.  The environments studied were Preserved Forest
- reference area, Cajarana Orchard Area, Corn/Bean Consortium,
Watermelon/Pumpkin Consortium, and Agroecological Cultivation. The
Preserved Forest presented the highest field capacity, permanent wilting
point, and available water. The study concluded that the soil tillage
systems alter the chemical, physical and structural attributes of Cambisols
of the semiarid area studied and that minimum tillage is the most suitable
tillage system for the region.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at ways to improve the productivity of the rice-wheat
system in the eastern Gangetic Plains of South Asia. They evaluated the
performance of three RW system intensification options with different
management interventions over two years, comparing a conventional RW
rotation (CS1), with two stages of conservation agriculture (CA)
interventions, (i) the simple inclusion of mungbean (CS2), and (ii) the
inclusion of mungbean together with full CA implementation (CS3) at two
sites in the EGP that differed with respect to soil type, water table
dynamics, and agro-climatic conditions. The addition of mungbean into the
conventional RW rotation produced significantly higher system productivity
(rice equivalent yield, REY) compared with the existing double-crop
rotation across sites. The baseline system was enhanced further when
CA-based management practices were adopted, however, the magnitude of
system benefit from CA was site and situation-specific.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This is an interesting article that looks equipment needs for smallholder
vegetable growers to switch to no-till techniques using cover crops and
reduce heavy physical labor use. Lack of no-till equipment has hampered
adoption of NT and CC's that provide many benefits for farmers. Equipment
evaluated included no-till drills, roller/crimper and NT transplanter for
walk behind tractors to manage use of cover crops or transplanted seedling
vegetables like tomato in a no-till system. Results from this experiment
indicate that developed experimental equipment can be a practical solution
for small no-till farming operations with cover crops.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This unique paper describes existing sugarcane farming practices and some
improved cultivation and management practices using the principles of
conservation agriculture (CA) are evaluated in Bangladesh. Excessive
tillage, burning of trash after harvesting, and mono-cropping have been
identified as crucial factors that increase sugarcane production cost,
deteriorating soil health, and decreasing cane yields. Inter-cropping is
suggested as a way to increase economic benefits and overcome negative
problems of mono-cropping. The paper recommends that no-tillage, residue
mulching, and intercropping should be applied as profitable and sustainable
cultivation practices in sugarcane farming.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study looked at the physical attributes and organic carbon contents of
a clayey Oxisol in an area under four different land uses for 10 years:
afforestation (AF), no-tillage system with grass-grass succession
(corn/corn), no-tillage systems with grass-legume succession
(corn/Crotalaria juncea L.) and conventional soil tillage system
(corn/fallow in Brazil. The areas were sampled at 3 different depths and
evaluated for soil aggregation and porosity using multivariate factor
analysis. The no-tillage system promoted soil aggregation and porosity
similar to that of the planted forest and superior to those of the
conventional tillage system. The type of crop succession in the no-tillage
system caused differences in soil structure, and grass-grass succession
(corn/corn) promoted better soil structure compared to other systems. The
greater soil porosity generated by the conventional tillage system was
limited to the most superficial layer but the presence of large amounts of
smaller aggregates can clog the generated pores.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This letter suggests that the development and adoption of a single
agricultural practice may not help in the holistic mitigation of the
impacts of climate change and may result in economic vulnerability to
farmers. Instead there is a need to develop and recommend a group of
agricultural practices having compatibility for one another. The research
used a library search to look at CA, SRI, Organic and soil applied biochar
as the major agronomic practices being used to improve ecosystem services
such as improving nutrient cycling, soil fertility and crop productivity as
well as climate change mitigation. The letter mentions the issue of
adoption but suggests that scientific communities are exploring the role of
combined agricultural practices.

https://doi.org/10.1016/j.geoderma.2020.114911
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper reports on the effect of cover crops on modifying soil surface
response to penetration and the relation to soil water content. The
research used two crops, barley and vetch, as cover crops and compared them
with a bare fallow in a 10 year long term trial in Spain. The soil
resistance to penetration was closely related to the surface soil water
content (R2 = 0.65) and cover crops affected it through soil moisture
modification. The greater biomass of barley compared to vetch increased the
soil water content prior to main crop seeding and reduced the resistance to
penetration. The good performance of barley resulted in a reduction of more
than 60% of the soil resistance to penetration between the 3rd and 8th year
of the experiment. Even under bare fallow, soil strength was decreased
after ten years with reduced tillage. The maintenance of cover crop
residues over surface soil together with reduced tillage enhanced the soil
surface conditions and steadily reduced the risk of crust formation.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study evaluates the climate resilience in terms of profitability and
risk management that determine farm-level adaptation. This 27 year
long-term study looked at three agricultural treatments. for a
corn-soybean-wheat rotation in Michigan. The three alternative treatments
were no-till, reduced input and certified organic that were compared with
conventional practices for the same rotation. Results demonstrate that the
net revenues from the organic treatment are exceed the net revenues of
conventional treatment. The no-till treatment dominates conventional and
reduced input practices in annual net revenues with a relatively lower risk
to those revenues in light of climate extremes. They concluded the organic
and no-till treatments were deemed climate-resilient whereas the
conventional and reduced input treatments did not show resilience will be
vulnerable to the changing climate. But growers have been slow to adopt the
two climate resilient practices and this needs further study.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study was conducted at three different locations in South Dakota, USA,
to compare the natural (undisturbed) ecosystem (NE) with the tilled (CT)
and no-tilled (NT) practices, and to evaluate the tillage effects on soil
organic carbon (SOC) and total nitrogen (TN) contents, bulk density (ρb),
enzymatic activities and aggregate stability under a corn (Zea mays
L.)-soybean (Glycine max L.) cropping system. Results support that NT
practices improved soil aggregation as compared to the CT and stored higher
SOC and TN concentrations in the aggregates, however, NE treatment
outperformed both the tillage systems. Their comparative evaluation with a
NE treatment concludes that tilled practices negatively affect soil
properties but recommend adoption of NT farming to enhance the soil
properties in agroecosystems.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This is an interesting paper from Cambodia looking at nematode issues in
lowland rice managed using CA. They compared nematode populations, rice
yield and soil organic matter in conservation agriculture management,
conventional rice systems with greenmanure management (GMCT) and
conventional plough-based tillage systems. Results demonstrated that GMCT
for one year (GMCT1) and the long-term CA for seven years (CA7) reduced
nematode densities in both soil and in rice roots, almost throughout the
study period, compared to the CT system. For rice yield components and soil
fertility, CA7 proved to be effective in increasing plant height, the
number of tillers/plant and soil organic matter.
