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.

The A1 horizon is neutral at 6.7 _h20 in the, trending towards strongly acid in the subsoil. The cation exchange capacity is moderate in the A1 horizon at 16.0 meq/100g trending to low in the B2 horizon at 9.80 meq/100g. This indicates the soil has limited to moderate ability to hold and supply nutrients to the tree. Due to the acidity, Aluminium levels in the B22 horizon are considered toxic as they exceed the toxic threshold for apple trees of 0.4 meq/100g. The organic carbon content in the A1 horizon is moderate at 1.50 % for a topsoil. The soil profile is not saline and not sodic.
