Compaction caused by machinery traffic can have severe yield consequences. Compaction increases soil strength and reduces soil porosity, which hinders root growth, moisture and nutrient uptake, and plant growth.

Carried out as a summer scholarship between December 2012 and March 2013, the researcher sought to outline the potential contribution of corn in rotation with cotton, in comparison to historical cotton and wheat rotat

This PhD project aims to determine the mechanisms, by which soil sodicity impacts on the uptake of nutrients and growth of cotton crops, in order that soil sodium levels can be factored into crop nutritional managemen

A growth disorder of cotton ( Gossypium hirsutum) occurs in irrigated cracking clay soils in cotton growing regions of northern New South Wales.
