Residues of grain corn production consist of:
- stalks which make up about 52.5% of the whole mass of the residues. At that, the stalk makes up 27.3% of the mass of the whole plant including grain (the same indexes are presented below for other parts of corn residues);
- leaves – 20.0 % (10.6%);
- cobs – 17.5% (9.0%);
- wrap of ear – 8.5% (4.3%);
- other parts – 1.5% (0.8%).
Production of agricultural residues, including corn residues, is seasonable and depends on harvesting periods. Grain corn is harvested during different time frames, depending on the variety, the place of cultivation and the time of sowing. Usually, time frame for harvesting corn is determined by the level of grain moisture, so before harvesting, they determine the moisture content of the grain and its ripeness, taking into account the terms of sowing and the hybrid ripeness group. By the beginning of harvesting, the corn grain must have a high dry matter content (at least 45%).
