Greater impact on SOC

This study aimed to investigate the impact of integrated application of inorganic fertilizer (NPK) and farmyard manure (FYM) on soybean grain nutrient uptake and yield. We performed field experiments with treatments including 100% NPK, 150% NPK, 100% NPK+FYM and control (without fertilizer), and soil properties and plant parameters assessed. Greater effects on soil electric conductivity (EC), soil organic carbon (SOC), Soil N were recorded with treatments.

The results demonstrated that BGRs did not affect SOC negatively over a period of ten years. The simulation predicted similar effect of BGRs and cattle slurry on SOC. The analysis of the cropping system showed that the changes in cropping system had greater impact on SOC than fertilization.
