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 at 7.2-7.3 h20 throughout the soil profile. The cation exchange capacity of the A1 horizon at 18 meq/100g is classed as moderate, whilst in the B21 and B22 horizons the CEC of 11 meq/100g is low. The organic carbon content in the A1 horizon at 2.9 % is considered high, whilst the organic carbon content of the B21 horizon at 1.1 % is unusually high for a subsoil. All three soil horizons are classed as moderately sodic, and all soil layers are noted to contain a low level of salinity (EC).
