The soil analysis will give the farmer key information on the fertility of the soil which allows the farmer to improve soil fertility and crop yields, reduce fertiliser costs and make better use of slurry and manures.
The soil analysis report states the pH and the P & K of the soil. The pH is a measure of the acidity and how it can be corrected by the application of lime. The optimum value for arable crops is 6.5 and for grassland 6.0. The pH of soil tends to decline over time. The optimum index of two for phosphorus and two- for potassium will maximise crop yield from the most economic use of inputs.
