Abstract:
Fertilizer nitrogen recovery under fallow and under a wheat crop (Triticum aestivum L., Cv. Miriam) grown on a deep loessial silty loam (Calcixerollic Xerochrept), was studied with 18N labelled KN03. The labelled nitrogen was applied (at a rate of 180 kg/ha) to 30 cm diameter microplots enclosed in hard plastic tubes that protruded 5 cm above the soil surface. In the 1st year of the experiment there was a long dry spell during the main part of the growing season and plant dry-matter yields were low. The 2nd year was wet, with heavy rain early in the season. About one-third of the fertilizer N applied to the fallow was lost from the top 60 cm layer in the 1st year. Most of the fertilizer N remaining in the soil as mineral N at the end of the first season was lost in the 2nd year. The possible reasons for such low N-conservation efficiency are discussed. © 1985, Cambridge University Press. All rights reserved.
