FIELD: mineral fertilizers.
SUBSTANCE: lime-magnesium ash fertilizers obtained from industrial utilization products for use in agriculture and forestry contain dolomite flower and peat flower with no more than 12% moisture, ratio of dolomite flower to peat flower being 1:3, whilst optimum calcium/magnesium ratio in fertilizer is 5:2 and, in another embodiment of invention, 7.5:2.5. Fertilizer enriches soil with silicates, neutralizes excess acidity and is particularly effective on sand and sub-sand soils having acid reaction and low content of magnesium and colloidal silicon.
EFFECT: increased assortment of inexpensive mineral fertilizers.
