Effects of Agronomic Measures on Decomposition Characteristics of Wheat and Maize Straw in China

The utilization of crop straw resources has been highly emphasized by governments and academia in recent decades. growing importance decomposition the wheat-maize rotation system remarkable diversity accumulated information on this topic inspired us to quantitatively explore variations outcomes individual studies. We conducted a data analysis 46 experimental studies reporting effects agronomic measures rates wheat (14 studies) maize (38 studies). Statistical results showed that crushed buried soil with turn-over or rotary tillage can significantly increase rates. Further, nitrogen input burial depth soil, rate increased significantly, while amount return opposite trend. Among all research, demonstrated significant positive effect rate. random forest identified time as most important predictor for maize. In addition, some jointly affect straw. general, are effective factors controlling system.
