Biogas fertilizer is a kind of organic fertilizer containing both nitrogen, phosphorus, and potassium. It contains a lot of volatile ammonia nitrogen. If the application method is improper, it is easy to lose fertilizer efficiency, and can not achieve the desired effect of increasing production. Here are the biogas fertilizer application techniques: Access Control System,Door Access Control System,Door Entry Systems,Door Access System Zhuhai Mingke Electronics Technology Co., Ltd , https://www.mingke-tech.com
When you go with you, you shouldn’t live long
In other words, it is taken from the biogas digester directly to the fields or the soil. If it is too busy, it can only be piled outside the pond for a day or two. After a long time, the available nitrogen will evaporate. Experiments have shown that the methane slag is dried and stored in the open air, with about 65% loss of total nitrogen and 87% loss of ammonia nitrogen.
Biogas slag fertilizer should be used as base fertilizer deep application
Applying to paddy field, it is best to use it when plowing, so that the mud and fertilizer are combined. The application amount is about 2000 kg per mu; when applied to dry soil, it is better to concentrate the application, such as acupuncture and furrow application, and then cover a layer of about 100 mm. Thick soil to reduce the volatilization of available nutrients.
Biogas water and fertilizer should be used as top dressing
When applying, it should be diluted with water according to the quality of the biogas fertilizer and the growth of the crop so as not to harm the young roots and young leaves of the crop.
Combined application of biogas fertilizer and chemical fertilizer
Ammonia and ammonium bicarbonate are nitrogen fertilizers with lower production costs, which are alkaline, and the volatile points of the fertilizer are lost. The combination of biogas slurry and ammonia water and ammonium bicarbonate can help dissolve the fertilizer in the soil, adsorb and stimulate the crops to absorb nutrients, and increase the utilization of chemical fertilizers. For every 50 kilograms of biogas fertilizer, 0.5-1 kg of ammonium bicarbonate or ammonia can be added.
The combined application of biogas slag and superphosphate can also improve the effect of superphosphate.
