Only the decomposed poultry manure can be called organic fertilizer, and the undeveloped poultry manure can be said to be hazardous fertilizer.
During the fermentation process of livestock manure, through the action of microorganisms, the organic matter in the manure is converted into nutrients that are easy for crops to absorb, so that it can be called organic fertilizer.
We can often see in rural areas that many vegetable farmers and fruit farmers apply immature organic fertilizer directly to the fields. What kind of harm will this cause?
1. Burn roots and seedlings.
Fermented livestock and poultry manure is applied to the fruit and vegetable garden. Due to incomplete fermentation, re-fermentation will occur. When the fermentation conditions are available, the heat generated by the fermentation will affect the growth of crops, causing “root burning and seedling burning”, which is serious Sometimes it will cause the plant to die.
2. Breeding diseases and insects.
Uncomposted and fermented livestock and poultry manure contains bacteria and pests such as coliforms and nematodes. Direct use will cause the spread of pests, disease of crops, and affect the health of people who eat agricultural products.
3. Producing poisonous gas and lack of oxygen.
In the process of decomposing and fermenting livestock and poultry manure, it will consume the oxygen in the soil and make the soil in an oxygen-deficient state. In this oxygen-deficient state, the growth of plants will be inhibited to a certain extent.
What are the benefits of applying thoroughly decomposed organic fertilizer to the soil?
The thoroughly decomposed and fermented poultry manure is a fertilizer with very rich nutrients and long-lasting effect. It is very helpful to the growth of crops, to increase the production and income of crops, and to increase the income of farmers.
Benefits 1. Organic fertilizer can produce various vitamins, phenols, enzymes, auxins and other substances during the decomposition process, which is beneficial to the balance of soil nutrients, the absorption and utilization of soil nutrients by crops, and prevents soil nutrient imbalance. It can promote the growth of crop roots and the absorption of nutrients.
Benefit 2. Organic fertilizer contains a large amount of organic matter, which is the food that microorganisms multiply in the soil. The more organic matter content, the better the physical properties of the soil, the stronger the soil retention, water retention, and fertilizer retention capacity, the better the aeration performance, and the more conducive to the growth of crop roots.
Benefit 3. The use of chemical fertilizers will aggravate soil acidification and salinization, destroy the soil aggregate structure, and cause compaction. Mixing with organic fertilizer can improve the buffering capacity of the soil, effectively adjust the pH, and keep the soil acidic. After the organic fertilizer decomposes, it can provide energy and nutrients for the soil microorganisms, promote the reproduction of microorganisms, and accelerate the decomposition of organic matter, enrich the nutrients of the soil, improve the soil structure, and improve the cold resistance, drought resistance and acid and alkali resistance of plants.
