Partial substitution of chemical fertilizer with organic fertilizer over seven years increases yields and restores soil bacterial community diversity in wheat–rice rotation

Substituting chemical fertilizer with organic fertilizer is an important agricultural practice that
improves crop yields but also affects soil biogeochemical cycling. To explore the effects of
organic fertilizer on soil properties and bacterial community structure and diversity, a long-
term field experiment (2011–2017) was conducted in a wheat–rice rotation system with four
treatments: control (CK, no fertilizer), chemical fertilizer only (NPK), substitution of 50% of
chemical nitrogen (N) fertilizer with organic fertilizer (NPKM), and substitution of 100% of …
