Abstract:
Summary of results: This project was needed to assess the N fertiliser requirements of cotton under new tillage systems currently being adopted, particularly since the structure of cracking clay soils is prone to degradation under intensive cultivation and traffic of continuous cropping. With little chance of extreme drying and cracking to restore soil structure, the trend towards continuous cropping may force soil management towards systems that allow maintenance and natural regeneration of soil structure. Such systems are likely to be based on permanent beds with minimum disturbance. Following is a summary of results; a detailed report is appended.
