*Conservation Agriculture (CA) is an ecological approach to regenerative
sustainable agriculture and ecosystem management based on the practical
application of context-specific and locally adapted three interlinked
principles of: (i) Continuous no or minimum mechanical soil disturbance
(no-till seeding/planting and weeding, and minimum soil disturbance with
all other farm operations including harvesting); (ii) permanent
maintenance of soil mulch cover (crop biomass, stubble and cover crops);
and (iii) diversification of cropping system (economically, environmentally
and socially adapted rotations and/or sequences and/or associations
involving annuals and/or perennials, including legumes and cover
crops).* *These
practices are complemented with other complementary good agricultural
production and land management practices to generate and sustain optimum
performance.*

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper uses a long-term farming system experiment to evaluate and
compare the agronomic, economic and ecological performance of the most
common arable cropping systems in Europe: organic, conservation, and
conventional farming. It contains data for 43 agroecosystem properties and
determines overall multifunctionality. Organic production resulted in
higher economic performance, thanks to higher product prices and additional
support payments. Our results demonstrate that different cropping systems
provide opposing services, enforcing the productivity-environmental
protection dilemma for agroecosystem functioning.

https://doi.org/10.1038/s41598-021-87594-0
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper suggests CA is a promising strategy to address challenges of
climate change and food security in Africa but lacks viable entry points
and short-term benefits for smallholders that limits adoption. The study
looks at legume intensification as a possible way to make CA more
attractive. Rotations of maize with intensified legume systems were tested
for three consecutive years under ridge and furrow (RF) tillage and CA to
investigate: (a) increases in productivity of legumes and the subsequent
maize crop; (b) changes in land equivalent ratios (LERs) and; (c) improved
total system productivity. They conclude that the doubled-up legumes
systems have great potential to improve household food security when
integrated into current smallholder farming.

https://doi.org/10.7717/peerj.11064
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study examined the effects of no-till and straw mulch on crop
productivity and greenhouse gas fluxes in agroecosystems on the Plateau
where farmers' common practice of conventional tillage (CT) was tested
against three CA practices: conventional tillage with straw mulch (CTS),
no-till (NT) and no-till with straw mulch (NTS). All three CA practices
(CTS, NTand NTS) markedly increased soil water content (SWC), soil organic
carbon (SOC) and soil total nitrogen (STN) but reduced soil temperature
(ST). CTS, NT and NTS yields increased by approximately 33%, 9% and 41%
respectively compared with CT without residue. There were significant
reductions of Net CO2 emissions under NT and NTS compared with CTS and CT.
Sustainable soil moisture improvement practices such as no-till, straw
mulch, green manuring, contour ploughing and terracing can improve crop
resilience to climate change and reduce GHG emissions in arid and semi-arid
regions.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This article is part of a special issue on CA in this journal. Weeds vary
greatly in CA systems since they react differently to different habitats.
This research observed the species diversity and shifts in different CA
rotations. Monoculture maize (MM) under both conventional tillage (CT) and
CA crop systems was accordingly evaluated against two-year and three-year
rotation CA systems of maize with cowpea and sunflower respectively. Weed
species diversity remained constant across seasons. Some weed species
shifts were observed in sandy loam soil site.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
The paper contends that CA offers climate adaptation benefits, but suggest
that effects of CA on yield are elusive. They analyzed 29-years of climate
data, cotton yield, and soil data under 32 management practices in
Tennessee, USA. They found that long-term no-tillage enhanced agroecosystem
resilience and yield stability under climate extremes and maximized yield
under favorable climate tied to enhanced soil structural stability and
organic carbon. No-tillage enhanced the effectiveness of a legume cover
crop in stabilizing cotton yield during relatively dry or wet, and dry
years, while nitrogen fertilizer rate and precipitation timing, controlled
yield stability in wetter years.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at micro-economic evidence of the welfare effects of CA
using recent panel data from Ethiopia combined with novel historical
weather data. They use a panel data endogenous switching regression model
to deal with selection bias and farmer heterogeneity in CA choice. The
study finds that the CA practices that play a pivotal role in addressing
the exigencies of rural poverty are minimum tillage, cereal-legume
intercropping, and their combination. These practices reduce the incidence
and depth of poverty in areas prone to rainfall stress, which is an
indication of their risk mitigation role. They caution against exaggerated
expectations of CA's economic benefits and a rigid recommendation of CA.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This article is included since rice residue burning in parts of India has
become a major issue affecting air quality, human health, soil nutrient and
biodiversity loss. Once a wealth, the straw has become a waste subjected to
burning due to technical, structural, institutional, and socioeconomic
challenges. This paper describes multiple alternate uses of this biomass
instead of burning including its use in CA management. The economic and
environmental gains and losses of alternate straw management options were
estimated and shown to be economic and provide an environmental gain and
give a key insight to policy makers to tackle this complex issue of
straw-burning.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study looks at residue management in CA systems on the black cotton
soils (vertisols) of India. Retention of soybean and wheat residues in
black soils under a no-till system is important to protect the land from
degradation. The main objective of this study was to test the effect of
different levels of soybean and wheat residue retention on the physical,
chemical, and biological properties of black soil. Four levels of soybean
and wheat residue retention (no residue, 30, 60, and 90%) on soil
properties was evaluated. Soil organic carbon (C) significantly increased
from 0.67 to 1.0% in 5 years through 90% residue retention. Retention of
90% soybean and wheat residues (7.0 and 13.8 t ha, respectively)
significantly improved the physical, chemical, and biological properties of
black soil in 5 years, therefore protected the soil from degradation.

https://doi.org/10.1071/SR20109
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
Soil compaction is a main issue threatening soil function and quality. This
paper evaluates tillage and wheeling effects on physical properties of
soils. The treatments were 13 years of no-tillage (NT), NT compacted with
additional wheeling (NTc), minimum tillage (chiselling) soil (MT), and MT
compacted with additional wheeling (MTc). Soil bulk density (Bd),
macroporosity (Mp), precompression stress (sigma p), compressibility
coefficient (Cc), and relative deformation were determined in four soil
layers. Surface compaction in conservation agriculture is a major issue,
since soil mobilisation by soil tillage should be avoided. Adding the
residue mulch component of CA would have been an interesting additional
treatment since other studies have shown that NT and mulch is better than
just NT.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This new series of book volumes is devoted to soil organic carbon, one of
the most crucial components of the Earth's climate system that can be
managed by humans. Soils as a carbon pool are key factors in some of the
Sustainable Development Goals, especially SDG 15 “Protect, restore and
promote sustainable use of terrestrial ecosystems, sustainably manage
forests, combat desertification and halt and reverse land degradation and
halt biodiversity loss”. The link for this Scoop is for Volume 1, one of 6,
that is an introduction to the full collection and presents the detailed
methodology and structure of the following volumes. It also lists and
describes the other 5 volumes.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper analyzes key stakeholders in the agricultural innovation system
(AIS) in Malawi using CA as an example. They analyze roles, organizational
capacity and collaboration of stakeholders in Malawi's CA innovation
system. NGOs dominate the national CA agenda, while smallholder farmers
remain passive recipients of CA interventions. Many CA promoters lack
technical and financial capacity, and pursue limited collaboration, which
diminish prospects of inclusive stakeholder engagement. Their findings
indicate a need to: (1) strengthen understanding of AIS approaches among CA
innovation system stakeholders; (2) build stronger partnerships in CA
research and development by strengthening stakeholder platforms and social
processes; (3) strengthen collaboration advisory mechanisms to facilitate
knowledge-sharing, resource mobilization and joint programme implementation
with strengthened feedback loops.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This 10-year CA experiment in China investigated the effects on soil
respiration and net carbon (C) flux in the wheat-maize cropping system, and
to identify the physicochemical controls of soil respiration C emission
under different tillage and residue managements. Compared with continuous
tillage, the reduced/no-tillage without residue significantly reduced soil
respiration rate. C emission was ascribed to the accumulation of organic C,
especially for the labile fraction, under residue returning than under
residue removing. The increased organic C stock in topsoil accounted for
the accelerated respiration C emission under reduced/no-tillage with
residues.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This is a chapter in a book with 30 chapters and over 600 pages on CA. The
author describes how NT is becoming a recognized way to grow crops and and
practice farming. The chapter goes on to describe the role of herbicides in
controlling weeds in NT farming. The use of herbicides has been increasing
in India due to shortages of farm labor and concerns about the
affordability of labor costs and are the primary drivers for the growing
popularity of agrochemicals and herbicides, which is expected to emerge as
a key growth segment. But herbicides are not the only way to control weeds
and an integrated approach should be used. Proper equipment and training in
proper use is also needed.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at the impact of CA and changes in crop rotation in the
last 15 years that led to less disturbance of mouse burrows and increased
ground cover and food supply on rodent pests. This study was justified
since irregular outbreaks of mice in grain cropping regions in Australia
and the damage they cause, makes it important to understand when and where
mouse populations increase so that management strategies can be improved.
They utilised a 20-year long-term mouse population data set collected prior
to the introduction of CA farming practices and a more recent 8-year data
set after CA to compare changes in mouse population abundance in a typical
dryland grain cropping system in Australia. Mice are now resident
year-round within crops and stubble and appear to only spill over into
margin habitats. Previously developed recommendations for mouse management
that include their control while in margin habitats may no longer be valid.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper discusses the importance of maintaining improved soil properties
in the light of land degradation, loss of biological diversity and
associated ecosystem services, climate change, food insecurity, and water
stress. The paper describes the contribution of CA to overcome these issues
using a review of literature. The authors make key recommendations for good
practices under each soil security pillar and conclude that empirical
research is required to deepen the understanding of the benefits of CA in
soil security, especially in developing countries.
