Tarnogran for cereals contains 4% of nitrogen in an ammonium form, 15% of phosphorate in the form of phosphorous pentoxide soluble in mineral acids, 20% of potassium oxide, 5% of calcium oxide, 2% of magnesium oxide, 13% of sulphur in the S03 form, as well as also 0,1% of copper, 0,1% of manganese and 0,1% of zinc.
Tarnogran for cereals contains nutrients in water-soluble forms which are easily absorbed by plants.
The start-up dose of nitrogen ensures proper initial growth of plants.
Phosphorus stimulates proper development of plant root system.
Potassium regulates water management of plants. The role of the microelements recommended in fertilising is:
Copper - has beneficial effects on nitrogen metabolism in a plant, it acts as a catalyst in photosynthesis.
Manganese - regulates and stimulates growth, takes part in the process of photosynthesis, production of chlorophyll and synthesis of proteins.
Zinc - increases effectiveness of nitrogen fertilization.
The fertiliser contains also secondary macro-nutrients: calcium, magnesium and sulphur, which have positive effects on the size and quality of the crop.
The Tarnogran fertiliser for cereals is a compound inorganic fertiliser intended for fertilizing winter and summer cereals as well as plants with a high demand for phosphorous and potassium.
Tarnogran for cereals should be used pior to sowing. It is recommended to mix it with soil to the depth of 10-15 cm.
