The fertiliser is suitable for all crops when preparing soil in spring. It penetrates the soil immediately after spreading. For fruit trees it is best used with phosphatic and potassic fertilisers. It is especially suitable for growing potatoes and crops that need a high sulphur content such as bulbous vegetables, cabbage-type vegetables and horse radish. The fertiliser has an acidic effect. The fertiliser is suitable for crops such as rape, sugar beet, sunflower, poppies, soya, winter wheat and corn.
