*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study looked at different strip-tillage blade designs to overcome
problems of poor seed coverage found using seeding machinery compatible
with CA on fine-textured clay soils in dry season cropping in South Asia.
Considering machine and energy costs, blade performance, and the necessity
of minimizing soil disturbance in strip-tillage, our study indicates that
the use of straight blades (four blades per row) operated at a depth of 75
or 100 mm are more ideal. These specifications are likely to enhance
strip-tillage stand establishment in fine-textured soils with high moisture
contents, though further work is needed under actual field conditions.

https://doi.org/10.1016/j.jclepro.2020.122700
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This paper looked at NT plus mulching to determine if it provides an
environmentally cleaner crop production practice that can enhance energy
use efficiency, economic profitability, and reduce the carbon footprint
(CF). It compared CT with NT with 4 different mulches - rice straw mulch
(RSM), Gliricidia sepium mulch (GLM), brown manuring mulch (BMM) of cowpea
(Vigna unguiculata), and no mulch (NM) as a control. The results suggested
that NT with BMM enhanced energy use efficiency, besides reducing the CF of
direct-seeded upland rice production system in the Eastern Himalayas and
similar eco-regions of the world.

https://doi.org/10.3390/SU12176730
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
Reduced nutrient mineralization rates under NT are usually compensated for
by addition of mineral fertilizer, but this is not allowed in organic
systems. This paper looked at an organic NT system based on cover cropping
to overcome the above problem in NT in two long-term experiments. They also
looked at compost addition versus mineral P and K fertilizer. Across both
experiments, macronutrients (+52%), micronutrients (+11%), microbial
biomass (+51%), microbial activity (+86%), and bacterivorous nematodes
(+112%) increased in NT compared to CT systems. They conclude that soil
fertility can be improved in organic NT systems, with cover cropping and
dead mulch, over plow-based systems.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This paper looks at ways to improve smallholder vegetable farms in Nepal
using CA and IPM. Data on yield, benefit-cost ratio (B:C), labor
requirement, insect and disease infestation, and pesticide sprays on five
major vegetable crops (tomato, cucumber, bitter gourd, cabbage,
cauliflower) were measured. Overall, the improved alternative system for
vegetable crops contributed not only to the improved income and livelihoods
of people, but also can improve environment and human health due to the
reduced use of pesticides. Further research on scaling these improved
alternative practices through appropriate farmer organizations, and
government and non-government actors can enhance the adoption of CA and IPM
practices by smallholder vegetable producers.

https://doi.org/10.1002/ldr.3833
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This paper says that despite positive biophysical benefits of CA, low
adoption rates have been the focus of several research projects. This study
uses a technographic and participatory approach to move beyond the adoption
framework and look at how agricultural decision making takes place, how
agriculture is performed in the context of project intervention and how
practice adaptation plays out in the context of interacting knowledge. The
study shows that the assumed model of technology transfer with reference to
climate-smart agriculture interventions is not as linear and effective as
assumed previously. The study suggests that the following 4 items need to
be understood (a) social dynamics and information transfer, (b) contextual
costs and benefits, (c) experience and risk aversion, and (d) practice
adaptation. Investments should build on existing knowledge and farming
systems including a focus on the dynamic decision process to support the
'scaling up, scaling out and scaling deep' agenda for sustainable
agricultural innovations.

prospects of CA in the wheat and rice basket of South Asia. In this region
recent cereal productivity has slowed down because of technological
stagnation and natural resource fatigue. Crop residues are considered a
vital natural resource for protecting and sustaining soil and crop
productivity and are useful for maintaining or enhancing soil organic
matter (SOM). This chapter presents the perspectives on soil and
environment through use of conservation agriculture (CA) for sustainable
cereal production system in the Indo-Gangetic belts of South Asia.

https://doi.org/10.1016/j.agsy.2014.06.009
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This paper was included because of the debate about use of residues in
crop-livestock systems in Africa and their impact on adoption of CA. The
area in Zimbabwe for this study is a semi-arid area where yields are low
and residue biomass is limited. The paper looks at the economic tradeoffs
and profitability of using residues for feeding the livestock or livestock
using household surveys. The results show that a maize-macuna rotation can
reduce tradeoffs of residues for mulch or feed. The results also show that
The poverty effects of all considered alternative biomass options are
limited; they do not raise income sufficiently to lift farmers out of
poverty. Further research is needed to establish the competitiveness of
alternative biomass enhancing technologies and the socio-economic processes
that can facilitate sustainable intensification of mixed crop-livestock
systems, particularly in semi-arid environments.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study identified a site under a long-term NT production system where a
known compaction force of 0 Mg axle load (control, C-0), two (C-2) and four
(C-4) passages of 2.5 Mg water wagon axle load was applied to cover the
entire plot for 20 consecutive years to assess changes in soil hydraulic
properties at a site in the Central Ohio, USA. The field was under NT-based
corn–soybean rotation since 1997. A wooded lot was chosen as a baseline for
comparison. They concluded that further monitoring of the impacts of
compaction on soil hydraulic properties particularly on some other

https://www.researchgate.net/publication/344631396_INTEGRATED_CROP_RESIDUES_MANAGEMENT_FOR_A_SUSTAINABLE_AGRICULTURE_ONLY_ANSWER_TO_THE_STUBLE_BURNING_-A_REVIEW
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
Stubble burning of rice and other crops is a common practice globally to
avoid the cost of clearing the field for the next crop. But this results in
environmental pollution and GHG emissions and can also affect soil health.
Efforts are being made to develop techniques of using crop residues as an
alternative to stubble burning, which are economically viable and are
eco-friendly. Examples include animal feed, fodder, fuel like bioethanol,
biochar, packaging, mushroom cultivation, composting etc. Adoption of
conservation agriculture-based technologies using these crop residues will
also avoid the problems of stubble burning.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This is a unique paper looking at slugs as a possible issue by comparing
populations from CT and CA in Italy. Predators such as ground beetles are
an integrated way to control slugs and their numbers are also measured.
Slugs were were common in CT than CA with more beetles in the CA, mulched
plots. Soil management such as minimum- or no-tillage and the presence of
cover crops/mulch are important elements influencing both slug and ground
beetle presence, possibly playing a key role in the maintenance of natural
enemy populations.

*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study explored the effects of CA on earthworms in a semi-arid climate
of the eastern Cape, South Africa. It looked at the effects of tillage,
residue and rotations on earthworm abundance. Earthworm species diversity
and density were highest under no-till than under CT. Residue retention
improved earthworm density regardless of tillage management. Rotations that
had fallow periods recorded lower earthworm numbers as compared to
continuous cropping systems where wheat was grown in winter. The study
concluded that maize;wheat;soybean (MWS) rotation with residue retention
results in the highest earthworm abundance and species richness.

https://doi.org/10.1111/aab.12622
*Cornell Conservation Agriculture Group (soilhealth.org)*s insight:
This study uses Collembola numbers as a good indicator of improved soil
properties following a change in land management. They looked at these
springtail populations in systems with a history of CA and crop-livestock
use in South Brazil. The samples were also evaluated for soil chemical,
physical and microbiological properties. CA and CLI management varied in
the association of different Collembola's -- epigeic in CA and hemiedaphic
and edaphic ones in CLI but these differences were related to different
soil conditions. They conclude that Collembola community structure and
species diversity were modified by the soil management systems and suggest
that the Collembola community may indicate changes across land management
systems in conservation agriculture.

Chapter 17 in a 2021 book, "Improving Cereal Productivity Through Climate
Smart Practices". An article looking at laser land leveling combined with
CA to produce more crop per drop of water. But the chapter also looks at
other factors besides NT that are required and obtained by adopting CA. It
concludes that to achieve the higher productivity and profitability,
adoption of a multipronged strategy of using improved varieties, balanced
fertilization, appropriate irrigation, and weed management practices are a
must.
