*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study assessed the relationships between soil health and cropping
system performance for three maize-based cropping systems in New Caledonia.
There were two CA systems compared a conventional tillage system: direct
seeding into dead mulch (CA-DM) and into a stylo living mulch (CA-LM). Soil
health was evaluated using Biofunctool®, a set of ten in-field tools that
assess soil carbon transformation, structure maintenance and nutrient
cycling functions. Weeds, maize growth and yield components were monitored
using a Structual Equation model (SEM). Soil structure maintenance and
nutrient cycling functions were higher under CA-DM and CA-LM than under CT,
and carbon transformation function was higher under CA-DM than under CT and
CA-LM. Overall, the soil health index (SHI) was 1.3-fold higher under CA
systems than under CT.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This review of CA in South Africa shows growth over the last few decades
worldwide, as well as in South Africa. Because of the numerous benefits, CA
is viewed by many as the more sustainable alternative to conventional
agricultural practice but cautions there are many challenges associated
with CA. This paper explains the basic principles, a brief history, and
provides a discussion of the benefits and challenges associated with the
approach in South Africa. This paper also serves as an introduction to a
Special Issue on conservation agriculture in South Africa.

https://doi.org/10.1016/j.jenvman.2021.112893
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This Ethiopian study assessed the long-term impact of different
conservation management systems (CMS) on soil organic carbon (SOC) using
the DAYCENT model over a 30 year period. The management systems considered
were minimum tillage, crop residue (CR) retention, fertilization and their
combinations.Data came from studies in the literature. The alternate
systems were compared with the business as usual treatment (BAU). Results
showed CMS increased SOC in the 0-20 cm layer compared to BAU. The
individual effect of fertilization, CR retention or minimum tillage
management practices on SOC stock were lower than the response of the
combined conservation management practices. They conclude that the combined
50–75% CR retention, NT, and increased N fertilization have a potential to
increase SOC sequestration in resource-limited smallholding croplands.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This experimental field study looked at no-till (NT) and different amounts
of corn stover. The treatments were no-till with no corn stover mulch
(NT-0); no-till with 2.5 t ha−1 corn stover mulch (NT-33 %); no-till with 5
t ha−1 corn stover mulch (NT-67 %); no-till with 7.5 t ha−1 corn stover
mulch (NT-100 %), and conventional tillage (CT) as a control treatment. The
abundance, diversity, and composition of the mesofauna were measured to
estimate the potential interacting effects on the mesofauna of no-till with
different amounts of corn stover mulch. The results showed that compared
with CT, no-till with corn stover mulch altered the mesofauna communities
and demonstrated that the corn stover mulch was an important factor in
supporting more abundant and diverse mesofauna.

https://doi.org/10.1016/j.still.2021.105068
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study looks at an improved tillage tool for use in heavy residue that
improves penetration, with less force, better straw cutting and minimizes
soil disturbance. A biomimetic disc mimicking the mole-rat’s claw was
fabricated and evaluated in comparison with traditional discs (i.e. a plain
and a notched disc) in straw mulched soil. Tests were done at 3 soil
depths. The claw-shaped edges easily penetrate through densely mulched soil
while avoiding tool-sliding over the straw, and achieves minimum soil
disturbance. The biomimetic tool design thus presents a viable solution for
the conflicting performance requirements by conservation tillage in
intensive farming systems.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This 7-year field experiment using the rice-wheat cropping system in
Haryana, India looked at weed management issues in this system. Weed
infestation was more intensified and diversified in direct seeded rice
(DSR) than puddled transplanted rice (PTR), and even eliminating puddling
in rice-induced more infestation of Phalaris minor in succeeding wheat
crop. Residue retention in zero-till (ZT) DSR and rotating conventional
till (CT) DSR with PTR reduced weed pressure compared to continuous DSR.
Root knot and plant parasitic nematodes were less in DSR than PTR but
reverse was true for saprozoic nematodes in DSR and ZT situations. There
was also improvement in soil health under ZTDSR/MTR (higher OC, N, P and K,
and lower bulk density) compared to PTR.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper analyzes the impact of community-embedded farmer education
programs on the adoption of conservation farming in Kenya, Malawi,
Mozambique, and Tanzania. They use a multinomial choice model to estimate
the relative risk ratios (RRR) that measures the probability of adopting
CA. They conclude that The positive role of community-based dissemination
programs potentially means that the dissemination of conservation
agriculture requires investments by governments and development
organizations in community learning sites. Investments in experiential
(hands-on) and farmer self-learning in farmer education programs may be
critical in enabling the diffusion of better farming methods.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study tested the hypothesis that CA has contributed to the
sustainability of Brazilian soybean production with positive effects on
soil quality, grain yield and nutritional quality and growers
profitability. They conclude that CA enhanced carbon sequestration,
physical and especially biological quality of soil, which caused improved
soybean grains yield, protein and flavonoids content and profit. This
compares with the traditional annual soybean and maize double crop (Zea
mays), that reduced soil physical quality with impacts on food security and
agricultural sustainability. Sustainability of Brazilian soybean production
can be increased by inserting crop rotations involving cover crops in the
rotation cycle.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study evaluated in the short-term (7 months) the dynamics of several
abiotic and biotic soil parameters under contrasting tillage systems in
France. Three tillage systems were investigated: conventional tillage (with
the soil inverted up to 25 cm depth) reduced tillage (limited to the first
7–8 cm depth) and no-tillage. Collembola and earthworms were sampled at
each plot using standard methods. Abiotic parameters (bulk density, SOC
stock, Mean Weight Diameter (MWD) and aggregates size) and microflora
(microbial and fungal biomass and their activity) were also monitored and
used as explaining factors. They conclude that overall, conservation
tillage can foster one of the numerous services provided by the soil
compartment, namely the soil biodiversity and therefore improve soil
quality and health.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
I attached this book information for people interested in CA in Africa. The
book will be available in December 2021. Agriculture in Africa today faces
major challenges including increased costs, climate change effects and a
need for more sustainable production intensification methods. This book
looks at Conservation (no-tillage) agriculture as a major alternative
sustainable agriculture practice in Africa including its spread to various
African countries in the past decade as more development and research has
enabled its extension and uptake. The material was presented at the Second
Africa Congress on Conservation Agriculture which was held in Johannesburg,
South Africa, 9-12 October 2018. The main theme of the Congress was: Making
Climate Smart Agriculture Real in Africa with Conservation Agriculture:

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study in Mexico where CA is often been used on permanent raised beds
(PB) not tilled, evaluated how PB widths in wheat, maize, and barley. The
study selected 9 sites where 6 were rainfed and 3 irrigated. They found
that bed width did not affect crop yield. Therefore, farmers can choose the
width suitable for their conditions. Some suggestions were: mechanical
weeding was easier in narrow beds, fuel use lower for shaping in wide beds,
irrigation water use the same in wide beds and narrow beds where the latter
is irrigated with alternate rows. Concentration of residue in windrows of
wide beds easier. Also suggested soil texture important since it affects
infiltration of water.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
Nepal has enacted an agricultural agenda on mechanization to improve ,
productivity, address labor scarcity, economic growth and sustainability.
Yet Nepal has yet to see substantial mechanization in agriculture. This
research aimed to provide a baseline to understand progress made towards
Agri-mechanisation on the Nepal Terai. They used a non-binary ‘Stepwise
Process of Mechanisation’ framework for this investigation. Across nearly
all machinery, a primary reason for limited progression to sustained
adoption was a lack of service providers, a manifestation of limited
machinery ownership, meaning current broad subsidy programs aimed at
procurement may not be achieving intended outcomes. With targeted
intervention, rapid rural mechanisation is possible in the near future in
Nepal. This work lays the foundation for future work to explore the
drivers, implications and inclusiveness of agri-mechanisation, utilising
the identified typologies, both in Nepal and more broadly where increased
nuance in understanding the status of agricultural mechanisation is
warranted.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This 6-year study examined the residual effect of tillage and nutrient
management applied to summer rice on root growth-attributes and impact on
morpho-physiology of succeeding winter pea grown uniformly under NT.
Increased root exudation was observed under NT and MT (minimum till) along
with organic residue addition. Also, enhanced chlorophyll pigmentation and
favourable leaf characteristics were observed in the pea crop grown under
NT with 50% NPK+weed biomass (WB)/green leaf manure (GLM) applications.
They conclude that adoption of MT/NT along with 50% NPK+WB/GLM in summer
rice is recommended for inducing favourable root environment and optimised
pea production in succeeding winter season in study region of the Eastern
Himalayas,

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study evaluated eight integrated crop management (ICM) systems in the
rice-wheat systems of NW India where direct seeded rice followed by NT
wheat are seen. The various ICM's evaluated were ICM1&2- conventional
transplanted rice fb flatbed wheat (check), ICM3&4- conventional direct
seeded rice (DSR) fb furrow irrigated raised bed wheat without residues,
ICM5&6- conservation agriculture (CA)-based modules [zero tilled (ZT) DSR
and ZT wheat] with the wheat and rice residues, and ICM7&8- CA-based
modules (ZTDSR and ZT wheat) with wheat, mungbean and rice residues. They
conclude that it is important to to have adequate input integration and
adoption of CA based ICM's, especially ICM 7&8, improved the soil carbon
dynamics, crop yields, farm profits, and provided water savings

https://doi.org/10.1016/j.still.2021.105075
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This seven years study was done to study the effects of different tillage
practices and residue levels on weed shift, diversity and crop yields.
Results show that annual weed species were dominant in conventional tillage
(CT) and reduced tillage (RT), whereas a shift towards perennials was
observed in zero tillage (ZT). CT recorded lower weed densities after 7
years. A shift in dicot weed species with higher weed density and biomass
and a small decrease in monocot weeds was observed in ZT. The anchored
residues 10 and 30 cm, recorded lower monocots and total weed count over no
residue. They conclude that integrated weed management (combination of
herbicide and removal of chance weeds) are efficient strategies to minimise
the weed infestation in CA and these methods not only reduce the over
reliance on herbicides but also improve the productivity of pigeon pea
(Cajanus cajan L.), castor (Ricinus communis).
