Effects of long-term organic fertilizer and straw on soil quality and crop yield in a rapeseed-maize rotation system.

ABSTRACT: This study aimed to pursue more sustainable agriculture in a new rapeseed-maize rotation system. We assessed the effects of organic fertilizer and straw on soil quality and crop yield through a 15-year field experiment: mainly applied organic fertilizer (MM); mainly applied inorganic fertilizer with straw (MCS); mainly applied inorganic fertilizer (MC); applied only inorganic fertilizer with straw (CS); and applied only inorganic fertilizer (C) as a control. Compared to the C treatment, crop yields, soil organic carbon (SOC), available nitrogen (AN), phosphorus (AP), potassium (AK), soil porosity (SP), field capacity (FC), and 0.250-2.000 mm large aggregates in soil water-stable aggregates (WA0.250-2.000) were significantly (P<0.05) increased by organic fertilization treatments (MCS, MC, a
