Apparent fertilizer nitrogen recovery and residual soil nitrate under continuous potato cropping: Effect of N fertilization rate and timing

Adequate nitrogen (N) fertilization is crucial to optimize yield and quality of potato and also to minimize N environmental losses. Effects of rates and timing of N fertilizer on residual soil nitrate (RSN) [NO 3 -N, 0-0.7 m], soil solution nitrate (SWN) concentrations and apparent fertilizer nitrog...
