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 in the topsoil 7.3 _h20, which trends to slightly acid in the B2 horizon. The cation exchange capacity in the A1 and A2 horizons is low ranging from 12.0 meq/100g in the A11 to 6.2 meq/100g in the A21 horizon. Whereas the CEC of the subsoil B2 horizon is moderate at 17 meq/100g. The organic carbon content at 1.5 % in the A11 and A12 horizons is considered moderate. All soil horizons are classed as moderately sodic, and all soil layers are noted to contain a moderate level of salinity (EC).
