This project utilises information from Emerald and other irrigation districts in the State to develop a scheduling system, WATERSCHED, as part of a Cotton Management Decision Program. OBJECTIVES 1.

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 degr

AIMS 1. To determine the mechanical and physical consequences of land preparation and harvesting on the soils and to relate these effects to soil water content. 2.

The aim of the project is twofold: to draw up a nitrogen budget for cotton under various conditions that are known to affect the crop's response to nitrogen; and to continue to develop the SJRATAC fruit model, in
