There are many nutrients in biogas sludge. The biogas slurry contains not only nitrogen, phosphorus, potassium fertilizer, organic matter and humic acid, but also many trace elements. The amino acids contained in the biogas slurry play a positive role in the healthy growth of animals and plants. The following biogas purification manufacturers will give you a detailed introduction!
Nutrients in biogas slurry are mostly soluble and can be fully absorbed by animals and plants. Although biogas sludge is a waste, it has high application value and resource attributes, and can be recycled to actively promote the steady development of industrial production of biogas engineering and serve agricultural production activities.
The technology of subsurface irrigation of farmland biogas slurry and slag can utilize the biogas sludge quickly and efficiently, and realize the resource utilization of biogas slurry and slag. According to the determination, the total nitrogen content, total phosphorus content, total potassium content and crop utilization ratio of the general biogas sludge are 40%-60%, 40%-50%, 80%-90% and 10%-20% higher than those of compost.
In addition, as additives, crude fibers which are not easily absorbed by animals in feed can be decomposed into a variety of soluble substances to form complex digestive enzymes. These enzymes can play a catalytic role in promoting digestion, absorption and metabolism, thus speeding up the growth and development of livestock and poultry.
