All applications should be encouraged to improve soil fertility, workability and structure providing full account is taken of the enhanced nutrient status of the soil so that risk of leaching or run off and residues in the product at harvest are minimised. Any application is only permitted following consideration of optimum crop requirements, recent soil analysis and cropping history.
Co-operative Retail strongly recommends the use of models and balance sheets to improve the accuracy of such operations on farm. Manner, EMA, Planet (PLANET is a computerised version of Defra's industry standard 'Fertiliser Recommendations 'RB209' book) can be used to demonstrate of good agricultural practice.
Do not apply fertilisers to conservation areas or wildlife corridors.
