The Fertiliser Advisory Service also offers routine and supplementary analyses on liquid and granular fertilisers, urea, CMS, composts and manures.
Analysis of these nutrient sources is a critical element of proper soil nutrient management planning. Reliable data on the nutrient composition of products is essential for optimising yields and preventing environmental pollution by nutrient ‘overloads’.
