Corn has reached a development stage that allows the use of foliar fertilization. The main ingredient that should be provided to plants at this time is zinc, boron, phosphorus and potassium. Zinc is an essential microelement in corn cultivation: it has a positive effect on increasing the resistance of plants to abiotic stresses, increases the quality and quantity of crops and improves the efficiency of nitrogen fertilization. Boron has a positive effect on the growth and development of the root system and proper filling of the cob with seeds. In many regions of Poland, we observe periodic soil drought – it is worth using VitaExpert Stress Control in such conditions.

VitaExpert Stress Control  – foliar organic-mineral fertilizer stimulating plant immunity under abiotic stress conditions (drought, high temperature) with the addition of proline. Particularly recommended for crops that have a high demand for potassium and during periods of soil drought.
