Soil Chemistry Overview
This data reflects both the natural elemental composition at the site and the historical influence of nutrient management. Some soil properties such as organic carbon indicate overall soil health, whilst other such as Sodicity, Aluminium and salinity may indicate constraints to root growth and soil water extraction. Comparison between sites of the same soil type will help better understand the difference between these two influencing factors. High or low levels of some nutrients may indicate that some changes in nutrient management may be necessary and we suggest that you contact your local agronomist for their recommendations.
Soil pH is slightly acid in the topsoil at 6.5 h20, trending to acid in the subsoil at 4.1 h20 in the B2 horizon. Although not measured pHCaCl2 below 4.7 indicate potential for aluminium toxicity. The cation exchange capacity of the topsoil is low at only 3.43 meq/100g, which probably reflects the lower than expected organic carbon content at only 1.62 %. The soil profile is not saline or sodic. Potassium and Sulphur are noted to be low.
