Download pdf: Soil sampling and different methods of arable cultivation 4. Soil sampling for the routine measurement of P, K, Mg indices and pH is familiar to most advisers and farmers. The cores are then bulked before laboratory analysis to determine average field P, K and Mg concentrations. Traditionally, this is the plough layer, which is deeper than the soil sampling depth. Nutrient concentrations in the cores taken are designed to represent those in the plough layer, i. Things are rather different where minimum cultivation is practised.

The soil test method provides a step-by-step process to soil sampling and analysis required to calculate the fertiliser rate for nitrogen and phosphorus. Soil testing provides information to enable you to fine-tune your nutrient application to meet the needs of the crop. Under the reef protection regulations, you need to soil test blocks within 12 months prior to planting and analyse the soil content for:. Once you collect the soil, you should identify a suitable ASPAC certified laboratory to undertake soil analysis using the following methods:. Please note that it is important that these methods are used as they are known to provide nutrient recommendations best suited to crop requirements.
