Role

To conduct research into soil physical aspects restricting sugarcane yields.

To develop procedures and guidelines to improve the soil environment for sustained sugarcane production.

To transfer technology to extension officers, growers and other role-players in the SA sugar industry.

To manage a portfolio of research projects within the SDO programme.

Expertise

Water storage capacity of soils, soil salinity/sodicity, soil compaction, tillage practices, root distribution, sugarcane trash blankets, organic ameliorants, soil health.

Research Interests

Impact of clay type & quantity and organic matter on soil water relationships, root distribution, buffer capacity of the soil against degradation and soil health indicators.
Modelling root growth & distribution and crop water use.
The purpose and outcomes of long-term trials.
Measurements to quantify the condition of soils.
Promoting crop rotation, organic matter use and by-product re-cycling within the sugar industry.

Key Outcomes

Carbon distribution between shoots and roots.
Water balance model for stressed sugarcane.
Tillage techniques to improve yields on marginal soils.
Nutritional and yield benefits of sugarcane trash blankets and other organic products.
Soil health indicators for the SA sugar industry.
