Project Objectives: Part A: (i) To study the effect of wet/dry cycles with drying by evaporation alone in ameliorating degraded furrows in retained hill cotton (at the Fressor site). (ii) To quantify the soil structure changes in (i) and relate them to soil physical properties. Part B: (i) To study the relative effect of rotation crops (evaporation alone and no crops) in ameliorating degraded furrows in retained hill cotton (at the Leadbetter site). (ii) To quantify the structure changes in (i) and relate them to growing rotation crops.
