The Dangers of Unrotted Chicken Manure

What are the safety risks of unrotted chicken manure? Is it related to yellow leaf disease of small leaf poplar disease of fruit trees? Is it true that the application of chicken manure is more costly fee than the use of product organic fertilizer?

Note that chicken manure is not solved or not well decomposed and immediately used on crops, there are greater hazards and safety risks, specifically in.

(1) Infectious diseases. Excrement with pathogenic bacteria and pests such as coliform bacteria, ciliates, etc., the immediate application will cause the spread of disease, crop disease, and health hazards to edible agricultural products; unrotted organic chemical materials in the soil fermentation, very easy to grow pathogenic bacteria and pests, but also cause green plant diseases; especially fruit trees, the application of unrotted chicken manure is very easy to cause fruit tree roots downy mildew outbreak, is what you see a small tumor like items deposited at the root, "robbed" the nutrients of the rootstock, blocking the water, nutrients delivery, so that fruit trees by strong weakening (small leaves poplar withered) and decline (root rot) and die ......

(2) Fermentation burns young seedlings. Not fermented raw manure and other organic chemical materials applied to the field, when the fermentation standards have, fermentation under the theme of bacterial activity, when the fermentation position is closer to the root and crop plants more clock, fermentation caused by calories will harm the growth and development of crops, damage the rootstock of crops, more serious when the plant death.

(3) Toxic gas injury. In the dissolution process caused by methane gas, ammonia and other harmful substances, so that the soil and crops caused by acid damage and root damage. Especially in the shed room, the damage is more serious.

(4)Insufficient soil oxygen. Soil organic matter in the dissolution process consumes the O2 in the soil, so that the soil is briefly in the oxygen deficiency situation, which will cause plant growth and development to be inhibited.

(5) Fertility retardation. Unfermented organic fertilizer nutrients in the organic chemical state or slow-acting state, can not be used by crops immediately adsorbed, only dissolved into a fast-acting state can be digested and absorbed by plants to use, so unfermented organic fertilizer immediately when the fertility is slow.

(6) The cost is relatively high without the immediate application of disposal, the volume of organic compound material is large, the relevant components are low, the transportation is not convenient, and the application cost is elevated.

Therefore, good friends of villagers who habitually apply chicken manure are careful, they need to pass a comprehensive maturation before use to enhance the fertility and reduce unnecessary damage.
