Agricultural cropping systems in coastal areas of China have experienced significant shifts, and nitrogen (N) and phosphorus (P) losses via surface runoff from fields have considerably increased. However, it is unclear how changes in cropping systems coupled with rainfall‐runoff affect nutrient losses in coastal areas. In this study, in‐situ daily rainfall‐runoff events in agricultural fields in the...
Although watershed nutrient exports have been well studied and modelled, the dynamic changes in the contributions of individual nutrient sources to reservoirs are less certain under changing land use and climate. The intensification of agriculture has led to expansion in plantation areas and the corresponding increased use of chemical and organic fertilisers in many headwater catchments in recent...
