TARNOGRAN must be used for all agricultural crops without exception, especially for cereals, rapeseed, sugar beet,
corn, legumes and
sunflower. TARNOGRAN is a multi-component
fertilizer, containing 12% phosphorus (P2O5) soluble in mineral acids, 23% potassium (K2O) in the form of potassium salt, 6% calcium (CaO), 4% magnesium in the composition of magnesium sulfate, 10% sulfur in the form of sulfur. According to the level of assimilation by plants, sulfur ranks fourth after nitrogen, potassium and phosphorus. It promotes assimilation of the necessary amount of nitrogen, improves plant vegetation and increases productivity. Calcium promotes the development of the root system and the formation of fruits. Magnesium, as a key element of chlorophyll, affects photosynthesis, the formation of carbohydrates and their transportation to the underground part of the plant. In its sulfur form, it provides better utilization of other nutrients.
