Straw mulching with fertilizer nitrogen: An approach for improving crop yield, soil nutrients and enzyme activities

Field experiments were conducted to study soil properties, soil enzymes activities, water use efficiency ( WUE ) and crop productivity after six years of soya bean straw mulching in the semi‐arid conditions of China. The experiment included four treatments: CK (Control), N (240 kg N ha ‐1 ), H (soya bean straw mulching at half rate 700 kg ha ‐1 with 240 kg N ha ‐1 ) and F (soya bean straw mulching at full rate 1,400 kg ha ‐1 with 240 kg N ha ‐1...
