The scheme of frozen corn rejuvenation

Peculiarities of feeding corn

To form 1 ton of grains with the relevant quantity of by-products, corn plants use 24-32 kg of nitrogen, 10-14 kg of phosphorus, 25-35 kg of potassium, 6-10 kg each of magnesium and calcium, 3-4 kg of sulphur, 11 g of boron, 14 g of copper, 110 g of mangan, 0.9 g of molybdenum, 85 g of zinc and 200 g of iron. Two significant stages are singled out in the corn plant development as to the provision of macro- and micro-nutrients: stages of 3-5 leaves and 6-8 leaves. At these stages the most effective method is to use foliar feeding. In the 3-5 leaves stage the corn plants form generative organs which determines their future yield. The presence of the nutrients, especially phosphorus and zinc conditions the number of corn cobs per plant and the grains in them. At the 6-8 leaves stage the primary (embryonic) root system die and the corn passes on to absorbing nutrients through secondary root system. At this stage the leaf area of corn grows actively, the formation of generative organs continues which result in intensive consumption of nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and zinc (Zn).
