*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper used two 6-year experiments on two soils, a sandy and a clay
soil to better understand the drivers of maize yields comparing CT with CA.
Soil chemical parameters, total plant nutrient uptake, rate of crop residue
decomposition, and arbuscular mycorrhizal fungi (AMF) colonization of maize
roots were assessed. Soil chemical properties only differed at the sandy
soil location with the mulched systems under no-tillage plus mulch (NT)
resulting in increased soil organic carbon levels, total nitrogen, and soil
available phosphorus as compared to conventional tillage with no mulch or
rotation (CT). NT and rotation resulted in highest AM fungal root
colonization rate of maize at the clay soil location. The authors recommend
a more holistic approach to cropping system assessment that includes a
higher number of abiotic and biotic determinants.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
The objectives of this study were to: i) assess the C-budget of land use
change for two contrasting climatic environments, ii) estimate the C
turnover time of the natural capital through no-till cropping systems, and
iii) determine the C pathway from soil under native vegetation to no-till
cropping systems. Three types of land use were used: a) undisturbed soil
under native vegetation as a check; b) degraded soil through continuous
tillage; and c) soil under continuous no-till cropping system with residue
mulch. They conclude that no-till cropping systems with residue mulch can
help recover natural capital.

https://doi.org/10.1016/j.energy.2021.120661
*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This study looks at 3 tillage scenarios, conventional (CT), moldboard (DT)
and no-tillage (NT) with and without straw mulch, on energy, yield and GHG
emissions in a maize-wheat system in NW India. No-tillage with straw mulch
reduced energy use compared to CT and DT. Although grain yield and net
energy gain was higher under DT with mulch (DTM) than NTM, yet latter
resulted in significantly higher energy productivity and energy use
efficiency. Minimal GHG emissions without yield penalty was achieved by
adopting NT with mulching. CT without residues was the least efficient
management practice.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at the determining factors that influence the adoption of
reduced tillage by smallholder farmers in Kenya. The data comes from 300
random selected households of maize dominated farming systems. 437 plot
level analysis using Probit regression estimates the decision model.Access
to extension information is the key determinant. Household labor
availability, land allocated for maize crop, and plot-level characteristics
such as soil type, plot size, and intercropping practice followed on the
plot are also found to have influenced adoption.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper reviews existing literature and provides an overview of farming
practices in Nepal, highlights near-term challenges associated with climate
change and food security, and discusses the role of CA as a climate-smart
strategy to minimize soil degradation and improve food security. Change are
needed because of changes in climate -- decreasing precipitation and
increases in average temperature. Techniques reviewed include crop
diversification, crop rotation, cover crops and minimum tillage, all of
which can reduce soil degradation. In addition, increasing crop residue
retention can result in greater C sequestration and crop yield and
reductions in greenhouse gas emissions.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This article published in Spain looks at CT vs NT systems on SOC, CO2
emissions and their relation to soil temperature and yield of maize from
2011-2017. The SOC stock of the top 30 cm soil layers was 13% greater under
NT than CT. Short-term CO2 emissions were significantly higher under CT
immediately after tillage while under the NT system, soil CO2 fluxes were
low and stable during this study period. They conclude that NT systems
increase SOC accumulation in the topsoil layer, reduce CO2 emissions
without decreasing maize grain yield and minimize the impact on climate
change compared to the CT system.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at the conversion of land use for paddy rice to oilseed
rape to vegetables on land degradation in China based on soil chemical
properties measure by soil analysis and farmer interviews.  In the
vegetable cropping system, fertilizer application often exceeds the crop
demand or levels recommended that lowers crop use efficiency for nutrients.
In the vegetable cropping system studied, SOC, C stock, TN, and N stock
were decreased significantly due to low organic inputs from crop residues
and high tillage frequency. They conclude that use of CA practices and
integrated soil-crop management help recover degraded soils and improve
vegetable productivity.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This article looks at the issue of weeds and the weed seed bank when
converting from CT to CA in Bangladesh intensive rice-based systems. Two
rotations were studied: wheat-mungbean-winter rice and monsoon
rice-mustard-winter rice. Strip tillage plus residues was compared with CT
and no residues. The weed seed bank was determined at several depths. After
2 years, ST+residue had a lower emerged weed count from the weed seed bank.
Overall, ST plus 50% residue had a more diverse seed bank than CT without
mulch. The majority of weed seeds were amassed in the 0-5 cm soil depth of
the ST, while most of them were accumulated in the 10-15 cm layer of the CT.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This 3-year field study in Italy examined how selected cover crops affect
yield performance in a maize - soybean under NT, and  assessed the effects
of CCs on inputs to the soil carbon and nitrogen, soil organic C (SOC) and
pools, as well as microarthropods and earthworms abundance and diversity.
Grain yield during the initial 2-yr period was on average reduced with CCs
by 1–23% in maize, and 1–33% in soybean. This effect was less evident with
CC residues having low C:N ratio. Thereafter, CCs had no effect on maize
yield in the third year. Soil organic C and pools over a 3-yr application
were limited to the topmost 5 cm of soil, and the biomass input with CC
residue and its C:N ratio are crucial for boosting soil C cycling. Results
on soil fauna showed that different groups or species need different time
for showing effects but many became effective after 3-years.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This discussion paper looks at the issue of land intensification or
extensification through land sparing or or land sharing on biodiversity.
The latter model and the issue of biodiversity is mainly driven by
conservation ecologists, but this paper presents other issues overlooked by
this simple either/or model from an agricultural scientist viewpoint who
have practical experience of farming in many global farming systems. The
authors raise two major limitations of this model above. that there are
synergies between agriculture and biodiversity  that are often overlooked;
and metrics that may be more important to farmers that are strongly
associated with positive biodiversity outcomes. They conclude that what is
needed is working together to identify viable solutions that increase
yields and help with biodiversity conservation.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This was a field experiment under CA in a maize-wheat system in the Indian
Punjab that also looked at sub-surface drip irrigation and nitrogen doses.
There were a number of treatments with residue retained or removed, N0,
N120 and N 150, permanent beds (PB) with furrow irrigation and sub-surface
drip irrigation, and conventional tillage. They conclude that maize yields
were higher under CA+ plots as compared to CA alone (PBWR-Furrow-N120) and
CT (CTWOR-Furrow-N120). The grain N content remained statistically similar
across all the N management plots, but in case of total N uptake, PB with
surface drip + N150 plots dominated due to higher biomass. It also recorded
the highest maize yields.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
The report examines the utility of innovation platforms to improve the
adoption of CA practices in South Asia and generate opportunities for rural
micro-entrepreneurship in areas with high rates of poverty, small farm
sizes and complex labour markets. The identified 37 villages in Nepal,
Bangladesh and Eastern India with smallholder farmers and input and output
suppliers. IPs were effective in developing trust in communities, among
stakeholders, empowering rural youth and women through direct engagement.
Ensuring strong ownership was key.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
In the IGP rice-wheat system farmers are adopting NT wheat but there is
limited data on the effect of CA on soil aggregation and enzyme activity.
This paper investigated the effects of direct seeded rice (DSR)-NTW,
DSR-NTW with brown manuring (BM) or mungbean (Vigna radiata) residue
retention (MBR) with rice residue retention (RR) on soil aggregation,
glomalin content and soil enzymatic activities after four years under an
irrigated rice–wheat system. DSR + MBR-ZTW + RR-ZTMB treatment resulted in
an improved soil microbial environment after four years of rice–wheat
cropping in the IGP. The enhanced soil properties were mainly due to
residue retention of crop residues, zero tillage (NT) in two crops (in the
first three years) and triple ZT (in the fourth year), and growing of a
legume crop in the conventional rice-wheat system in the IGP.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This article looks at the influence of different tillage practices on soil
microbial communities. They investigated the bacterial community structures
and assembly in bulk and rhizosphere soils of soybeans grown under
traditional tillage (moldboard plow, MP) and two conservation tillage
practices, namely, no-tillage (NT) and ridge tillage (RT). The latter two
reduced tillage systems increased the relative abundances of nitrifying
bacteria and the nitrogen-fixing bacteria of but decreased the abundance of
carbon-degrading bacteria. NT and RT resulted in a more stable bacterial
network structure and a lower homogenizing dispersal value. They conclude
that conservation tillage practices might help soil carbon sequestration,
while stimulating nitrogen fixation and nitrification.

*Cornell Conservation Agriculture Group (soilhealth.org)*'s insight:
This paper looks at sustainable and appropriate practices for sweet sorghum
smallholder farmers in South Africa and their affect on microbial biomass
carbon (MBC) and enzymes. They compare CT with NT, various rotations and
residue management. Tillage x rotation x residue interactions influenced
MBC. They conclude that Soil biological indicators were higher under NT and
30% residue retention respectively. NT + sorghum-vetch-sorghum rotation
+30% residue was a better treatment combination to enhance soil quality
under bioenergy sweet sorghum in South African marginal soils.
