TARNOGRAN K is a granular compound fertilizer containing: 3% of nitrogen (N) in the ammonium form, 10% of phosphorus (P2O5) soluble in mineral acids, 21% of potassium (K2O) in the form of potassium salt, 6% of calcium (CaO), 3% of magnesium (MgO) including 2% in the sulphate form , 18% of sulphur (SO3) and micro-nutrients: 0,3% of zinc (Zn) and 0,1% of boron (B).

Nitrogen – the starting dose of nitrogen ensures the proper growth of the plants.
Phosphorus – is present in the forms with various release rates.
Potassium – the basic yield-enhancing component in corn fertilization, present in the granule with magnesium sulphate, it is available throughout the vegetation period.
Magnesium – particularly important in the case of corn, present in easily absorbed sulphate form.
Sulphur – easily accessible sulphur in the sulphate form increases the yield-enhancing effect of nitrogen, improves the quality of the feed (green fodder, silage, grain), guarantees the good supply of micro-nutrients.
Zinc – affects the growth and health of the plants, controls the phosphorus and nitrogen management.
Boron – improves flowering and seed setting.


TARNOGRAN K is a specialized fertilizer containing the optimal set of macro- and micro-nutrients. It is intended primarily for the fertilization of corn and winter cereals, beets, legumes and fruit trees.


Principles of application

The fertilizer should be applied to soils with a pH ranging from neutral to acidic. It should be mixed with the soil to the depth of 10-15 cm.

Cultivated plants Depending on the content of phosphorus and potassium in the soil [kg/ha]
corn 500-800
sugar beets and fodder beets 550-900
winter cereals 300-500
fruit and bushes 350-600
