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’.

Where the material has been piled or stored in large heaps or windrows the following sampling procedure is advised:
Where the material is spread-out across a large area (e.g. kraal floor, chicken house floor) it is preferable to collect the material into a large well mixed pile or heap before following the above sampling procedure. Where this is not possible, then 20 – 30 subsamples collected in a zigzag pattern from the area and composite into a single sample for subsampling. Special care must be taken not to scrape soil or floor material when collecting the subsamples.
If sampling from bags, then sub sample each bag and thoroughly mix to create a single composite sample. Subsample about 500 grams for submission.
