BLACKZER Potassium Humate is a highly concentrated biostimulant consisting of humic and fulvic acids. It has positive effects on the physical properties of soils. BLACKZER K Humate improves water capacity, aeration and activation of microorganisms in the root system area. Moreover, it activates root growth and increases the uptake of nutrient elements. It acts in synergy with other fertilizers and increases the effects of chemical fertilizers.

It is effective in meeting the potassium needs of plants thanks to the potassium included in its structure during the production phase.

BLACKZER can be used in agricultural products, horticultural crops, fruit trees, ornamental plants and cereals. Thanks to its 100% water-solubility, it can also be used in foliar application and drip irrigation systems without clogging.
