Too much nitrogen delays the cobs, an excess of potassium harms the stalk. How to fertilize corn?

Corn belongs to plants with high nutritional needs, as with a yield of 1 ton of grain with the corresponding amount of straw, it absorbs an average of 29 kg of N, 13 kg of P 2 O 5, 33 kg of K 2 O, 9 kg of MgO, and 8 kg of CaO from the soil. It is also important to properly supply the plants with micronutrients, such as zinc and boron as well as copper, manganese, iron, and molybdenum, which affect the stabilization of the corn yield. In the initial growth period, corn absorbs small amounts of nutrients, and the increase in their uptake begins in the 7-8 leaf phase, gradually increasing in further developmental phases. When is it better to split nitrogen? In the case of nitrogen, its intensive uptake by corn begins a few days before flowering and increases until the plants mature. The timing of nitrogen fertilizer application depends, among other things, on the type of soil. For soils with a well-developed sorption complex, fertilizers are recommended to be used entirely before ...
