Conversion of nitrogen of ammonium nitrate and its assimilation by wheat in relation to rates and dates of application


, : Conversion of nitrogen of ammonium nitrate and its assimilation by wheat in relation to rates and dates of application. Trudy, Gruzinskii Nauchno issledovatel' skii Institut Pochvovedeniya, Agrokhimii i Melioratsii 16: 208-217

The coefficient of utilization of fertilizer N applied as ammonium nitrate to wheat in Georgian SSR was 38.4-53.2%, depending on rates and dates of application. After harvesting, 28.7-38.2% of the applied N remained in the soil and 13.8-26% was lost in gas exchange.
