Influence of Direct Use of Organic Fertilizer after Drying Under Sunshine
In some places, it is customary to use organic fertilizers such as pig manure manure, dried in the sun, or applied to the topsoil of dry crops directly. The result is that the manure is exposed to the sun and rain for a long time, and the nitrogen is basically volatilized and lost. Phosphorus and potassium will also be lost and pollute the environment. In some places, when straw is used as a source of organic fertilizer, the fermentation is not sufficient, and the rice plants are too concentrated. As a result, a large amount of sulfur is produced in the decay, and more bubbles are emitted, which makes the rice roots black. , the late seedlings etc. Not timely remediation will cause a dead seed in the whole field, causing a reduction in production. In this case, the field should be drained immediately, and in order to promote root growth, such as sodium, should be sprayed immediately after draining the field, and a 1% potassium dihydrogen phosphate and 1% urea mixed spray can also be added. By this way, to resume normal growth.
