Rice paddies supply half the global population with staple food, but also account for~ 48% of
greenhouse gas (GHG) emissions from croplands. In this Review, we outline the …

Agricultural soil acts as a source and sink of important greenhouse gases (GHGs) like
methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2). Rice paddies have been a …

Broadacre (arable) crops generally require a relatively higher nutrient input toward yield
targets. The efficient use of nutrients in arable farmlands is very vital to this endeavor. It …

Biochar amendment and substituting chemical fertilizers with organic manure (organic
substitution) have been widely reported to increase crop production and decrease reactive …

Milk vetch (Astragalus sinicus L.; MV) is the most common winter green manure used in rice
cropping systems in southern China. The utilization of MV can achieve the dual goals of soil …

Green manuring is a potential method for reducing chemical N fertilizer input and reactive N

Excessive chemical nitrogen (N) fertilizer application and flood irrigation in rice production
can lead to substantial soil-N losses and low nitrogen-use-efficiency (NUE) in rice due to N …

A large amount of nitrogen (N) fertilizer is required for paddy cultivation, but nitrogen use
efficiency (NUE) in paddy farming is low (20–40%). Much of the unutilized N potentially …

Soy whey is an abundant, nutrient-rich and safe wastewater produced in tofu processing, so
it is necessary to valorize it instead of discarding it as sewage. Whether soy whey can be …

Soil fertility management is one of the most important factors affecting crop production. The
