Due to contain high levels of organic matter should cassava residue is commonly used as organic fertilizer for crops. However, if applied directly, it does not bring high efficiency, the unpleasant odors, some researchers are now seeking to source recycled residue after starch processing into organic fertilizer using microorganisms.
The authors Luong Huu Thanh (Institute of Agricultural Environment) and Nguyen Kieu Bang Tam (University of Natural Sciences, VNU) also go towards this research.

The authors have used microbial products by the Department of Environmental Microbiology, Institute of Agricultural Environment offers (major components including actinomycetes, yeast, bacteria with cellulose reactive resolution, starch and distribution the insoluble phosphates), then incubated with cassava residue by the method of composting can add extra ingredients such as molasses, urea, potash, superphosphate, lime.
Results showed that, after 45 days of incubation, brown residue, porous, odorless; average pH; Organic matter content decreased more than 50% and not detecting pathogenic microorganisms. In particular, check the decomposed, for the safety of the plant, the residue was decomposed and found safe for plants - Journal of Soil Science No. 36/2011 for that.
In fact, the method of production of microbial production from waste starch have also been a number of units successfully applied, but also bring economic benefits, both to help curb environmental pollution.
