Profile Distribution of Nitrate-Nitrogen in an Alfisol Cropped to Continuous Cotton

J.S. McConnell, W.H. Baker and B.S. Frizzell


 
ABSTRACT

Nitrogen (N) fertilization of cotton (Gossypium hirsutum L.) has recently come under scrutiny as a potential source of nitrate (NO3-) contamination of streams and groundwater. This study was conducted to evaluate the distribution of NO3--N in soil cropped to continuous cotton and determine conditions that might exacerbate the accumulation of NO3--N.
