NITROGEN USE AND MANAGEMENT IN ORCHARDS AND VEGETABLE FIELDS IN CHINA: CHALLENGES AND SOLUTIONS
Xue‐Qiang Zhu
Abstract
Excessive application of N fertilizers in orchards and vegetable fields (OVFs) in China is particularly common. Long-term excessive application of N fertilizers has made OVFs hotspots for N surplus and loss in China. Nitrate accumulation in the soil profile is the main fate of N fertilizers in OVF systems. Reducing the N surplus is the most effective way to reduce N loss and increase NUE.
