Impact of straw management on seasonal soil carbon dioxide emissions, soil water content, and temperature in a semi-arid region of China

The use of crop residues as mulching materials or organic fertilizer, instead of burning, can help improve the soil organic carbon (SOC) and crop grain yield. An experiment was conducted for three consecutive seasons from 2013 to 2016, to study the effect of no straw (S0), S1/2 (700 kg/ha soybean straw, and 3000 kg/ha wheat straw), and S1 (1400 kg ha-1 soybean straw, and 6000 kg/ha wheat straw) treatments in wheat-soybean multi-crop system.
