*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This is the last chapter in this newly published book Scooped in last
December 15th newsletter. It summarizes 6 key themes from previous chapters
looking at sustainable and responsible agricultural food systems. Inclusive
responsibility reflects a move toward an alternative ethical framework
based on the core values of inclusion, interdependence, pluralism, justice,
equity, and care, and encompasses the six covered themes. Inclusive
responsibility can be integrated and applied at every level of the food and
agriculture system, from local to global, from production to consumption,
and from individual to community and society. The chapter concludes by
offering a possible vision for an inclusively responsible food and
agriculture system built on the agriculture paradigm of “Conservation
Agriculture-Based Veganic Agroecology.”

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
The objective of this study was to assess the changes in soil
physicochemical and microbiological parameters between four different
agricultural practices from a 7-year experiment using two seasons with
contrasting soil water content. They compared conventional tillage with
maize (CTM); no-till with maize (NTM); no-till with maize and soybean
rotated (NTM/S); no-till with annual rotation of maize intercropped with
Brachiaria rhuziziensis and soybean monoculture (NTMB/S) compared to a
long-term fallow (>40 years secondary forest) in both winter (rainy) and
summer (dry) seasons. In sum, they show that the benefits of conservation
agriculture for soil quality in this region were most obvious in the summer
and depended on the agricultural practices, with NTMB/S showing the
greatest conservation of soil physicochemical quality.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
The aim of this study was to assess factors influencing experimenting and
dis-adopting of CA using qualitative and econometric analysis in
Madagascar. They showed a high (56%) tryout rate followed by a 80%
dis-adoption rate. They conclude that monetary poverty (financial capital)
and agricultural work (social capital) decrease the likelihood farmers will
tryout CA. But the longer farmers receive CA technical support the less
likely they dis-adopt CA. They suggest that in order for farmers to use CA
to combat soil degradation it is important to tailor CA technology to the
diversity of farms, plus innovations need to be supported for a longer
period.

https://doi.org/10.1016/j.sciaf.2019.e00250
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
Climate smart agriculture can offer economic and food security for women
farmers but uptake of these technologies are limited by gendered
constraints. This study uses 344 women and men survey respondents involved
in conservation agriculture (CA) and small-scale irrigation schemes (SSIS)
as data sources for examining the effect of gendered constraints for
adopting climate-smart agriculture amongst women in three areas in
Ethiopia. The findings show that women smallholders uptake is affected by
limited access to credit, extension, restricted membership in cooperatives
and water user associations, lack of access or user rights to land, skill
training, information, and restricted mobility. Expanding off-farm
diversification and rural employment opportunities through changing the
land tenure system, which is currently state-owned, are essential to
enhance women smallholders’ access to land and other agricultural inputs.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
In mixed crop-livestock farming systems, smallholder farmers face the
challenge of insufficient dry season livestock feed whilst crop production
is mainly constrained by poor soil fertility and erratic rains. This study
evaluated the effects of maize-legume cropping systems on forage, maize
grain yield and gross margins. The cropping systems involved one
conventional tillage practice with continuous sole maize (CT), four CA
treatments consisting of continuous sole maize, maize-mucuna intercrop,
maize-cowpea intercrop and maize-groundnut/soybean rotations. The
experiment was replicated on eight farmers’ fields with each farmer treated
as a replicate. Maize-mucuna intercropping was the best of the tested
cropping systems with respect to forage yield and gross margin.

https://www.springer.com/gp/book/9783030464080
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
The adoption of NT systems has increased at an exponential rate since the
1990s and they are now used on 12.5% of global croplands. However, while
the development of NT systems has seen much success, there can be
significant agronomic, economic and/or social challenges associated with
their use that limit large scale worldwide adoption. In addition, where NT
is not implemented as part of an integrated system that incorporates
stubble retention and appropriate crop rotations to help manage weeds,
diseases, pests and soil fertility, decreases in yield can be observed.
This book covers opportunities and challenges in tailoring of NT farming
systems according to individual locations and the introduction of
flexibility in approach to manage some of the challenges of NT farming
systems.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This 5-year study looked at rice-wheat in NW India. The goal was to
identify management options for further improving productivity and
profitability and reducing environmental externalities by drawing on the
principles of diversification, precision management, and conservation
agriculture. There were four systems. 1. Business as usual transplanted
rice followed by tilled wheat; 2. TP rice fb ZT wheat and ZT mungbean; 3.
ZT for all 3 crops including ZTDS rice; ZT for a maize-wheat-mungbean
system. Results showed that compared to business as usual, the other 3
systems were more productive. These latter 3 systems were more productive
and profitable while using less water, energy, labor and lower global
warming potential. They conclude these SI entry points need to be placed in
the context of the major drivers of change in the region, including market
conditions, risks, and declining labor availability, and matching with the
needs and interests of different types of farmers.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study used on-farm participatory trials to compare the performance of
traditional versus conservation agriculture-based sustainable
intensification management practices in terms of labor, production costs
and gross margins to smallholder farmers. Trials were conducted on 400+
farms representing a range of crop management across the Eastern Gangetic
Plains. Overall, conservation agriculture-based practices reduced both
labor use and production costs by around 40% and increased gross margins
by up to 25% compared to conventional practices. This is important for
labor constrained smallholder cropping systems in this region.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study, in Central Malawi considered to have a relatively high uptake
of CA, uses analyses of satellite images, field observations, interviews
with farmers, extension workers and other people involved in CA promotion,
as well as a household survey, to investigate how CA has been adapted. They
found that continuous minimum tillage (no ridging), ground cover and crop
rotation/intercropping were not practiced as intended. One-third of
non-ridged land was tilled during the growing season, and half was again
ridged in the following season. Unless crop residues were added, the soil’s
surface of non-ridged plots was usually bare at planting, causing weed
control problems, and an increased risk of erosion. Most farmers added
large volumes of crop residues to their non-ridged plots. They collected
these from the surrounding fields, but this practice severely restricted the
size of these plots. Crop rotation/intercropping was practiced less when
farmers stopped ridging. Very few farmers practiced all three CA principles
simultaneously. CA promotion appeared to only increase yields on plots
where mulch was added. What was not discussed were suggestions for
alternate ways than CA to address the issue of soil degradation -- nutrient
mining, erosion and compaction. Also, in this area where ridging is
common, CA can be applied to these beds by keeping the beds permanent (just
reforming each season) and applying residue available in-situ or from other
sources on top of the beds. The last sentence of this paper also suggested
growing groundnuts. This is unlikely to address issues of land degradation
but would be a important as an intercrop with maize on permanent beds.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study looked at best management practices involving tillage and
residue management to obtain improved soil health for the important
rice-wheat cropping system of South Asia. Their soil quality index was
based on soil physical, chemical and biological properties. They looked at
conventional practices with transplanted rice followed by broadcast, tilled
wheat versus zero-tilled, direct seeded rice followed by ZT wheat. The
highest rice equivalent yield of 12.41 t ha-1 was observed at SQI values of
0.90 at 0-10 cm and 0.86 at 10-20 cm in the ZTDSR fb ZT wheat. They
conclude that crop residue retention on the surface with zero tillage is
beneficial for the sustainability and productivity of the RWCS in EIGP of
India.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
Challenges that have arisen with the adoption of NT include soil
compaction, weed management, and stratification of organic matter and
nutrients. As an attempt to overcome these challenges, occasional tillage
(OT) has been used as a soil management practice in NT systems. The
objectives of this meta-analysis were: 1) to summarize the effects of OT on
crop productivity, soil physical, chemical and biological properties, soil
erosion and weed control; 2) to discuss the main aspects of NT management
to optimize the use of OT; 3) to point out shortcomings in the diagnosis of
soil compaction in NT systems, which may lead to erroneous decision-making
processes regarding the use of OT. They conclude that proper NT
implementation and management, with the correct application of NT
principles, will overcome problems associated with NT. As soil compaction
is the main justification for the use of OT, methods of diagnosis and
monitoring of soil compaction should be improved to assist in
decision-making.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study compares CT with NT with stubble burning and stubble retention
and N fertilization on soil carbon and fractions and N. After 50 years, the
tillage regime, addition of N and stubble management were all important in
influencing carbon pools in the 0.1m depth with N and the tillage regime
the most important. But stubble management was important with retention
increasing total nitrogen content, stabilizing the C fraction, and
increasing the microbial biomass. They conclude the importance of stubble
retention and N fertilization in conservation agriculture clearly shows
improvement in soil health and maintenance of soil C levels.

https://doi.org/10.3390/agronomy10111746
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study compared three types of fallow management (ploughing (CT),
reduced tillage (RT), and no-till with glyphosate (NT)) on four fields
after 17 years of no-plough, which ended with 7 years of CA. Weed density
and species richness before weeding was greatest in RT, intermediate in CT
and lowest in NT. They conclude that potential benefits of occasional
ploughing will depend on the density and composition of the newly upwelled
weed seedbank, which will need to be assessed before implementing tillage.
From a multicriteria perspective, the long-term benefits associated with CA
could largely exceed short-term yield increases associated with occasional
tillage.
