Study finds multiple benefits from using biochar in agriculture

The use of appropriate nitrogen (N) rates is important to optimize organic rice yield potential while minimizing environmental impact and input costs. A greenhouse experiment was conducted to identify the optimal N rate for organic and conventional rice and determine its effects on rice yield, soil ...

Agricultural waste can have a catastrophic impact on climate change, as it contributes significantly to greenhouse gas (GHG) emissions if not managed sustainably. Swine-digestate-manure-derived biochar may be one sustainable way to manage waste and tackle GHG emissions in temperate climatic...

Conventional tillage (CT) degrades soil and environmental quality in many major cropping systems. Conservation agriculture, like reduced tillage, can play an important role in maintaining soil organic carbon (SOC) storage and in minimizing greenhouse gas (GHG) emissions from crop fields. An...

[Objective] Paddy fields are one of the important sources of greenhouse gas emissions, while farming practices and water management can reduce greenhouse gas emissions from field to a certain extent. Ridge cultivation and direct-seeding is a new kind of rice planting pattern that saves costs and...

Quantifying greenhouse gas (GHG) emissions from irrigated paddy fields is of great significance for addressing climate change. Machine learning (ML) provides an alternative to empirical models and biogeochemical models, but it has not been used to simulate GHG emissions from paddy fields. In this...

Biochar addition has been recommended as a potential strategy for mitigating climate change. However, the number of studies simultaneously investigating the effects of biochar addition on CO₂, N₂O and CH₄ emissions and sequentially global warming potential (GWP) is limited, especially concerning...

Biodegradable mulch film potentially offers an encouraging alternative to conventional (petroleum-based) plastic films. Since biodegradable films are more susceptible to rapid degradation, more microplastics (MPs) are likely to be generated than conventional films within the same time frame,...

Commonly, agricultural practices utilize urea as a nitrogen (N) source, which can lead to N losses to the environment. Application of urease inhibitors (UIs) or nitrification inhibitors (NIs) can mitigate these losses to some extent but not completely. A preliminary study showed that...

Increasing scarcity of irrigation water is threatening global wheat production and sustainability. Accordingly, the water-saving irrigation regime has been strongly advocated to reduce irrigation water consumption. However, studies about greenhouse gas (GHG) emissions from the winter wheat cropping ...
