Soil and Water Management
Major Funded projects

Reducing the persistence of Izamethapyr residues in acid soils

Enhancing the beneficial effect of pulses on wheat production

Sorption characteristics and degradation of some herbicides in Australian soils

Processes causing pH stratification of surface soils

Sustainable rotations through recharge control by enhanced lucerne water uptake

Effect of a polymer on soil water retention/release characteristics and plant water use efficiency

Controlled root zone irrigation

Effect of pulsing on wetting patterns with T-tape subsurface irrigation system

Research program:
Soil and Water Management

Program leader:
Dr Philip Eberbach

Main thrust:
Agriculture is a major export earner for Australia. The future for Australian agriculture depends upon the development of management practices which sustainably utilize the natural resource base _ namely soils and water. The thrust of research undertaken within this program deal with problems of significance to agricultural production within the Murray Darling Basin.

Aims
• To develop farming systems which reduce soil pH decline in higher rainfall areas of southern Australia

• To investigate the potential for phase farming to reduce groundwater recharge and reduce the spread of dryland salinization
• To improve irrigation practices to reduce water usage by crops and reduce recharge into groundwater systems
