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 neutral throughout the A and B2 horizons. The cation exchange capacity (CEC) in the topsoil A11 horizon is moderate at 13.0 meq/100g, however all other horizons are considered low. The organic carbon content in the topsoil (A11 horizon) at 2.1 % is high, and moderate in the A12 horizon. The topsoil layers A11 and A12 horizons are non-sodic and non-saline, whilst the subsoil B2 and B3 horizons are sodic but not saline. Phosphorous is noted to be low.
