Precautions for using farmyard manure (manure)

   Manure is an important farmyard fertilizer with more nitrogen and quicker fertilizer. It is also called quick-acting nitrogen fertilizer. It is quickly absorbed by plants and applied to many soil farmers and fruit farmers. Wait for manure. As a base fertilizer, manure is an organic fertilizer with full nutrients and can improve the soil. As a fertilizer, the vegetable farmers do not dare to apply chemical fertilizer because the greenhouse temperature in the winter and spring seasons is low or the ground temperature fails to rise to a suitable temperature range for vegetable growth. And used to apply manure, even directly to the soil to apply fresh manure. This kind of practice is worth improving. In the actual cultivation of vegetables, the application of manure must pay attention to the following points;

    First, the manure should be decomposed  

    Even if some manure is piled up for several months, or has been dried, it does not necessarily mean complete decomposing, but the moisture content inside is reduced, and the incomplete manure will cause the following problems:

    1. Rooting: Manure is applied to the soil. After planting the vegetables, with the watering, the incompletely decomposed manure will gradually mature and release a certain amount of heat, resulting in root burning or burning.

    2 , pests: feces often contain a variety of intestinal pathogens and parasite eggs, is an important way to spread disease. After manure application, it may cause an increase in pests due to incomplete decomposing, such as more chicken scorpions in chicken manure.

    3. Gas damage: The manure that is not completely decomposed slowly ferments and decomposes in the soil, and gradually releases some harmful gases such as ammonia or sulfur dioxide or hydrogen disulfide. If the content of such harmful gases is too high, or because the weather is cold, let the wind If it is not timely, harmful gases will accumulate in the shed, affecting the normal growth of vegetables and prone to gas damage.

    Second, the quality of some manure is poor

    Some manure is added with a certain amount of caustic soda, which can make one of the chicken manures expand to one and a half. The manure that "sends" looks like an increase in volume, but after the manure is applied to the soil, it will not only cause burnt roots, It also destroys the soil and causes adverse consequences for vegetable production. Chicken manure from individual dealers is spoiled with fake feathers or adulterated inferior fertilizer.

    Third, it is recommended that farmers and farmers ensure that the manure is fully fermented before using manure.
