The conditions of red clover dressing are defined to a great extent by the fertility of sward-podzolic soils. Having soil with low level of fertility (pH 5.2; P₂O₅ – 110; K₂O – 120 mg/kg of soil) after harvesting cover crop (in the fall) it is necessary to apply P₆₀K₉₀. Top dressing during the phase of budding at the beginning of clover blossom (in spring) is done with microfertilizers containing molybdenum. On soils with average level of fertility (pH 5.7; P₂O₅ – 185; K₂O – 190 mg/kg of soil) after harvesting cover crop it is necessary to apply P₄₀K₆₀ to dress clover. Top dressing during the phase of budding at the beginning of clover blossom is done with microfertilizers containing boron and molybdenum. On soils with high level of fertility (pH 6.2; P₂O₅ – 300; K₂O – 260 mg/kg of soil) after harvesting cover crop it is necessary to apply P₄₀K₆₀. Top dressing during the phase of budding at the beginning of clover blossom is made with microfertilizers containing boron.
