Production of microbial fertilizer from cassava residue

Due to high organic matter content, cassava residue is often used as organic fertilizer for plants. However, if direct application is not effective, causing bad odors, some studies are now looking for ways to recycle the residue after processing cassava starch into organic fertilizer by using microorganism.

The authors Luong Huu Thanh (Institute of Agricultural Environment) and Nguyen Kieu Bang Tam (University of Natural Sciences, Hanoi National University) also follow this research direction.

Use cassava residue to produce microbial fertilizer
both bring economic benefits and help reduce the box

The two authors used microbial inoculants provided by the Department of Environmental Microbiology, Institute of Agricultural Environment (main components include bacteriophage, yeast and bacteria with active cellulose resolution, starch and manure. Phosphate solution is difficult to dissolve), then compost with cassava residue by composting method with additional materials such as molasses, urea, potassium, super phosphate, lime powder.

The results showed that after 45 days of incubation, the residue was brown, porous, odorless; average pH; Organic matter content decreased by more than 50% and no pathogenic microorganisms were detected. In particular, checking the fertility, safety for plants of the product, it is found that waste residues are safe and safe for plants - Journal of Soil Science No. 36/2011 said.

In fact, the method of producing microbial fertilizer from cassava starch production has been applied quite successfully by some units, both bringing economic benefits and helping to limit environmental pollution.
