Straw mulching reduces the gaseous and leaching losses of fertilizer N from farmlands
Research gap analysis derived from 3 agriculture papers in our local library.
The gap
Although straw mulching reduces the gaseous and leaching losses of fertilizer N from farmlands, the dynamics of fertilizer-derived fixed NH 4 + and organic N and their roles in fertilizer N retention and supply in soil-crop systems remain unclear.

Previous studies have shown that applying inorganic nitrogen fertilizer can promote straw decomposition by adjusting the carbon-nitrogen ratio (C/N), but the dynamic effects of different organic nitrogen forms on straw decomposition and its mechanism remain uncertain–a research gap pivotal for optimizing fertilization strategies.

Partial substitution of synthetic fertilizer with straw or organic fertilizer improves soil quality, yet how it regulates gaseous nitrogen emissions, particularly through modulation of nitrifier and denitrifier microorganisms and enzyme activities, remains unclear.
