With the widescale uptake of minimum tillage, controlled traffic and precision farming techniques across Western Australia's grainbelt, new sampling guidelines are required to better measure nutrient availability in the soil. Current soil sampling techniques might not be giving growers a clear picture of what nutrients are available to a plant; how deep these nutrients might be in the soil profile; and where in the paddock the nutrients are most concentrated.

The aim of this project is to deliver a standard method for collection of soil samples, based on soil type and farming system to ensure consistent interpretation across the industry, allowing for more accurate and economic fertiliser decisions.
