摘要:
In recent years, traditional rice monoculture (RM) has led to agricultural intensification, resulting in loss of soil nutrients and the low fertility. Rice-crayfish (RC) integrated farming, as a sustainable agricultural system, could significantly enhance accumulation of soil C (carbon), N (nitrogen) and P (phosphorus) while improve soil fertility. However, it is still unknown how the characteristics of soil CNP stoichiometry and storage are influ-enced by long-term RC farming. This study examined the patterns of soil CNP storage and stoichiometry at 0-30 cm soil layers in RM and RC systems (1...
