A quantitative understanding of yield response to water and nutrients is key to improving the productivity and sustainability of rainfed cropping systems. Here, we quantified the effects of rainfall, fertilization (NPK) and soil organic amendments (with straw and manure) on yields of a rainfed wheat-soybean system in the North China Plain (NCP), using(More)
Soil organic carbon (SOC) sequestration is important for improving soil fertility of cropland and for the mitigation of greenhouse gas emissions to the atmosphere. The efficiency of SOC sequestration depends on the quantity and quality of the organic matter, soil type, and climate. Little is known about the SOC sequestration efficiency of organic amendments(More)
In order to test the efficacy of conservation tillage and optimized fertilization on reducing N and P runoff losses, a 4-year (2007–2011) runoff plot experiment was conducted in the Chaohu Lake region, East China. There were four treatments including: (1) conventional tillage (CT, basal fertilization without mulch), (2) conventional tillage with straw(More)
