Biogas fertilizer is a kind of green, environmental-friendly, high-quality and high-efficiency organic fertilizer with high and complete nutrient content. It can be used in vegetables to improve quality and increase yield. Attention should be paid to the following aspects in the application process.
The biogas manure cannot be applied immediately after leaving the pool. It is fermented under anaerobic conditions. It has strong reducing ability. If it is applied immediately after it is discharged, it will compete with crop roots for oxygen in the soil and affect the root function of vegetables. Therefore, after the biogas fertilizer is out of the tank, it is generally stored in the storage tank for 5 to 7 days, and the phosphate fertilizer can be added and mixed in a 10:1 ratio.
When biogas fertilizer is used for top dressing, it must be applied to the water diluted biogas fertilizer as top dressing. First, water must be used, and the water ratio should be generally 1:1. After the application of biogas fertilizer, it should be timely covered with soil in order to reduce the loss of fertilizer, and at the same time to be used with the use. Some experts have pointed out that: marsh fertilizer applied to the surface, if not timely cover, ammonium loss up to 50%. In addition, the amount of biogas fertilizer can not be too large, about 1200 kg per mu can be applied.
Biogas Fertilizers cannot be mixed with alkaline fertilizers. Fertilizers with strong alkalinity are mixed with biogas fertilizers, which will cause loss of nitrogen fertilizer and reduce fertilizer efficiency. In addition, before being used as a base fertilizer, biogas fertilizers should be properly stacked in storage tanks to kill some residual pathogens.
