The harm of using duck dung
The content of organic matter, nitrogen and phosphorus in duck manure is relatively high, crops can not be absorbed directly, fresh duck manure will attract underground pests. Not only does it not help crops, it also slows down their growth.
How to deal with fresh poultry manure
1. Poultry feces mainly refer to the feces of chickens, ducks, geese and so on. In all kinds of poultry, chickens and ducks feed on insects, fish, grain and grass, so the contents of organic matter, nitrogen and phosphorus in chicken and duck feces are higher than those in livestock and goose feces. Goose is a herbivorous poultry, its nutrient content and proportion are close to those of livestock, and its quality is not as good as that of chicken and duck manure.
2. The nitrogen in poultry feces is mainly uric acid, which can not be absorbed directly by crops. Its fertilizer effect on crops in the current season is equivalent to 50% of nitrogen fertilizer, but it has obvious aftereffect. The application of fresh poultry manure often attracts underground pests, so it must be applied after ripening. Rotten poultry manure is a kind of high-quality and quick-acting organic fertilizer, which is often used as the base fertilizer and topdressing of vegetables or cash crops, which can not only increase the yield, but also improve the quality of agricultural products.
