The Comparison of Different Fertilizer Technologies on Nitrogen Leaching Losses and Nitrogen Use Efficiency in Rice Production——Taking Ningxia Irrigation Region as an Example

The Comparison of Different Fertilizer Technologies on Nitrogen Leaching Losses and Nitrogen Use Efficiency in Rice Production——Taking Ningxia Irrigation Region as an Example

High N fertilizer and flooding irrigation applied to rice in anthropogenic-alluvial soil often result in N leaching and low use efficiency of applied fertilizer N from the rice field in Ningxia irrigation region in the upper reaches of the Yellow River. Sound N management practices need to be establ...
