Implication

Randomized trial investigates how nitrogen sources affect straw decomposition in cropland soils, suggesting improved nutrient recycling strategies.

Key Points

This research aims to understand how different nitrogen sources influence microbial community assembly and straw decomposition in various cropland soils.
Conducted five treatments with no N addition, urea, calcium nitrate, yeast derivatives, and glutamate.
Analyzed decomposition rates and microbial community changes across four soil types after 180 days.
Assessed microbial interaction networks and C release related to soil properties and nitrogen forms.
Straw decomposition rates varied by soil type, with cumulative rates ranging from 55.78% to 68.75% after 180 days.
Yeast derivatives increased straw decomposition by 15.00, 10.66, and 12.19 percentage points in three soil types within 14 days compared to no N addition.
Glutamate modified the fungal community structure, enhancing interactions and promoting later decomposition.
