Effects of straw return on soil nitrogen leaching

Nitrogen (N) is a major limiting factor for improvement in grain production. The return of straw to the soil (straw return) regarded as very effective option develop sustainable agriculture. Soil N content could be increased by because itself contains some nitrogen. However, whether retention worthy further study. In present study, laboratory simulative incubation experiment was conducted study effects addition on leaching from soil. experimental results showed that pH values with time were changed slightly different application, there no notable change relative abundance microbial taxa application at domain level, and EC did not show any clear trends after incorporation. highest 0.18 ds/m occurred 0.3%. Moreover, amounts decreased over time, higher amount added soil, greater
