Effects of combined application of pig manure composts prepared using different fermentation methods with chemical fertilizer on winter wheat yield, light-thermal physiology, and soil biological characteristics.

ABSTRACT:

Purpose

This study examined the effects and underlying mechanisms of combining pig manure composts, produced by different fermentation methods, with chemical fertilizers on winter wheat yield, nutrient uptake, light-thermal physiology, soil fertility, and microbial communities.

Methods

Field experiment was conducted in Yuanyang County, Henan Province (2023-2024) with the following treatments: no fertilizer (CK), chemical fertilizer (TK), combined organic-inorganic applications with 25:75 and 50:50 ratios. The 25:75 treatments included natural compost (TA1), water-controlled trough compost (TA2), acid-controlled trough compost (TA3), and trough compost (TA4) combined with chemical fertilizer; the 50:50 treatments included the same four compost types (TB1-TB4). Their effects o
