The Danger of Unripe Manure

1, Burning Roots and Seedlings 
After using incomplete fermentation of chicken manure, insert your hand into the soil, you will feel the soil temperature is high. The use of such chicken manure, serious will lead to the death of crops in pieces or full sheds, missed farming time, loss of labor and seedling investment. Especially in winter and spring, the application of chicken manure safety risks, because the high temperature in the greenhouse, chicken manure fermentation will emit a lot of heat, resulting in the phenomenon of root burning; orchard winter and spring use of chicken manure, just before and after the dormancy of the root system, once the root burning, will affect the nutrient accumulation and flowering and fruit next year.

2, Cause Soil Salinization 
The use of chicken manure for years, the soil retains a large amount of sodium chloride salt, an average of 30-40 kg of salt per 6 ㎡ chicken manure, and 10 kg of salt per mu of land has been seriously restricted soil permeability and activity, solidification of phosphorus fertilizer, potash, calcium, magnesium, zinc, iron, boron and manganese and other important elements, plant growth anomalies, flower buds fall, fruit yield reduction and other phenomena, greatly restricting the improvement of crop yield and quality.Therefore, the fertilizer utilization rate plummeted, a year is not as good as a year, increasing the input cost 50-100%.

3, Cause Soil Acidification 
As the pH value of chicken manure is about 4, is extremely acidic, will acidify the soil, resulting in chemical trauma and serious damage to the crop stem base and root tissue, to chicken manure carries a large number of viral pathogens, soil-borne disease carrying bacteria, viruses provide the entrance and infestation opportunities, humidity and temperature once the appropriate conditions will break out disease.The use of incompletely fermented chicken manure is very likely to cause plant wilting, yellowing, shrinkage and no growth, no flowers and no fruits, and even death. Virus disease, epidemic disease, stem rot, root rot, and green blight are the most obvious sequelae of using chicken manure.

4, Breeding Root Knot Nematode 
Chicken manure is the host and breeding ground of root-knot nematodes, and the number of root-knot nematode eggs carried by itself is 100 per 1000 grams, and the nematode eggs in chicken manure can easily hatch and multiply by tens of thousands overnight.The nematodes are extremely sensitive to chemicals and will quickly move to a depth of 50cm-1.5m underground after application, making it difficult to eradicate. Especially for 3 years old sheds, root knot nematode is one of the most deadly hidden problems.
