Something happened to the chicken manure

We visited one of the shed owners, Mr. Yu, who used chicken manure to grow cucumbers. The plants are growing well with green leaves and healthy roots, but subsequent daily wilting, accompanied by root rot, leads to a plummeting cucumber crop.

Yu invited experts to diagnose the incidence of plant disease, according to the on-the-spot investigation found that the roots of the exposure to the soil, drawn after found hidden in the inside of the soil root rot, basic nutrient blocked, therefore, cannot supply plants continue to blossom. In the process of pulling out, the soil was so hardened that green moss grew on the surface and white hairs of salt could be seen. Therefore, experts concluded that large amounts of chicken manure were applied to the land and that it was raw chicken manure without rotting heat and fermentation, which directly led to severe soil acidification and salinization.

Raw and dried chicken manure is a base fertilizer with little or no heat treatment, so stubborn and harmful bacteria and eggs remain. Chicken manure from the farm also contains a lot of Caustic soda, applied into the greenhouse leads to high soil salt content, so the long-term application of this kind of chicken manure will lead to more and more serious soil hardening, crop roots can not take root, and seedlings die. In the event of floods or high temperatures, roots can burn or rot, and further improper fertilization has a great impact on the capillary roots.
