With the excessive use of chemical fertilizers and pesticides in agricultural production, which has caused great damage to the soil and ecological environment, the state has begun to strictly control the use of chemical fertilizers and pesticides, and farmers’ friends have gradually realized that chemical fertilizers are not used much. The crops grew better and gradually began to be replaced with fertilizers during the planting process. Organic fertilizer is rich in organic matter, which can loosen the soil and provide various nutrients required in the growth process of crops. It is an amphoteric fertilizer, but to achieve good results, it must be applied more. If commercial organic fertilizers sold on the market are re-applied in this way, farmers will invest too much in some crops that are not particularly economical, and the investment returns will be too low.
Using pig manure in garden:
In addition to commercial organic fertilizers, my country also has a farming culture, so smart Chinese farmers already know how to collect animal manure and use plant straws as fertilizers. These farmyard fertilizers are also rich in organic and trace elements. This organic raw material is relatively common in rural areas and is cheap. Using them as fertilizers in planting production can not only make full use of the wastes of breeding and planting, but also enrich the soil, killing two birds with one stone.
Advantages and disadvantages of pig manure:
Nowadays, the feed of poultry and livestock contains a lot of salt, and some are added with hormones. The manure is originally the manure of poultry and livestock, which provides a good habitat for germs and pests. It is conceivable that high salt, heavy metals, germs and germs will not harm the soil less than the abuse of chemical fertilizers. The immature manure releases toxic gases such as ammonia into the soil that are not good for crops, causing the burning of seedlings. High salt and heavy metals damage the soil, germs, pests and diseases attack crops, resulting in the deterioration of the soil environment, the increase in crop diseases, and ultimately the crops have to reduce production or save water. Seriously affect the economic interests of farmers, can not get benefits.
Farm manure is an important source of organic matter in crop growth. Because not only comprehensive nutrients, but also rich organic matter are important for soil conservation, soil fertility and physical and chemical improvement and maintenance, as well as farmers’ use of fertilizers. However, in the actual use process, some problems caused by the use of farmyard fertilizers make growers love and hate, especially the unrotten farmyard fertilizers are more harmful to crops, what losses are caused, and how should they be used?
What are the dangers of using unfermented pig manure in farmland?
Using pig manure in garden requires Aerobic composting of pig manure, and the composted and fermented pig manure can be used for garden cultivation. Unfermented livestock and poultry excrement is suitable for farmland. Because the fermentation is not complete, the phenomenon of “second fermentation” will occur. As long as the fermentation conditions are met, the pig manure will be fermented under the activity of microorganisms. When the fermentation part is close to the root or the crop plant, the heat generated by the fermentation will affect the growth of the crop, causing “rooting and burning of the seedling”, and in severe cases, the plant will die. Feces contain bacteria and pests such as Escherichia coli and nematodes, and direct use will also affect the spread of pests and diseases, crop disease and the health of people who eat agricultural products. Immature organic matter is prone to bacteria and pests when fermented in the soil, leading to plant disease and pest outbreaks.
