SLURRY = B RO w N G OLD? A REVIE w OF SCIENTIFIC LITERATURE ON THE universities and, last but not least, smallholders themselves, are often not fully aware of the CO-p RODUCT OF BIOGAS p RODUCTION [SuMMARY In recent years, there has been an increasing interest in anaerobic digestion of farm and residues in many parts of the world.

With increasing of biogas slurry application, phosphorus deficit was alleviated, while the potassium deficit was aggravated. Applying appropriate amount of biogas slurry could increase the contents of nitrogen and potassium in soil, but it was difficult to meet the balance of phosphorus and potassium in soil by applying biogas slurry alone.

Biogas slurry (BS), a by-product of biogas production generated from anaerobic digestion of animal waste and crop residues, is often considered a substitute to reduce mineral fertilizer input. Being a cheap source of organic matter and plant nutrients, its application may …

Mainly, bio-slurry as the final waste from the biogas process that can no longer produce gas. In order to run biogas, manure and natural waste are needed, which are still fresh and have methane gas. So, bio-slurry is no longer required in the process, but it is still rich in nutrients that are good for the soil.
