Lower Yilgarn Catchment Appraisal 2003, D G. Cummins
Resource management technical reports
This report summarises current information on risks and impacts to agricultural production and natural resources within the Lower Yilgarn Catchment. It also identifies suitable options to manage such risks. The report has been divided into three sections : the natural resource base, the catchment risks and management options and impacts. Rapid Catchment Appraisal aims to document salinity risk and management options by addressing all threats to the natural resource base.

Productive agriculture increases the concentration of hydrogen ions in soil, which acidifies the soil.
Aluminium is a component of many soil constituents, including clays and oxides, and is also present on the surfaces of soil organic matter. As the concentration of hydrogen ions in soil increases, soil pH decreases, and aluminium starts to dissolve from the soil constituents, increasing the concentration of aluminium ions in soil solution.
As the concentration of aluminium ions in the solution increases, the aluminium in the soil solution becomes increasingly toxic to plant roots, reducing root growth. The smaller amounts of plant roots explore a …
