Farmers produce microbial fertilizers from coffee bean shells

Mr. Nguyen The Tien, Head of Agriculture Department of Di Linh District (Lam Dong) said that farmers in the district have recently mastered the microbial composting process from sub-waste of coffee shells. Since then, contributing to increasing soil fertility, increasing crop productivity, reducing investment, and reducing environmental pollution.

Lam Dong has many districts specializing in coffee crops such as Di Linh and Lam Ha . In previous years, after the harvest season, there are a large amount of waste products such as coffee shells, but mostly discarded into the environment or burned. . Some are reused as being put into coffee stumps or mixed with some types of manure and then applied to plants .

Therefore, the failure to properly handle coffee shells has contributed to waste, environmental pollution and dispersal of pathogens for the coffee crop next year.

Di Linh district in collaboration with the Central Institute of Agriculture and Forestry and a number of specialized universities opened 150 classes, each with 50 people, transferred scientific applications to compel microbial fermentation from coffee pods to farmers. At the end of the course, farmers directly work at households.

After about 3 months, farmers apply the proper techniques of coffee composting, in combination with using the right kind of good quality probiotics, which will give a bio-organic fertilizer with nutrient content. higher maintenance than good manure: three times the amount of potassium and 1.5 times the amount of phosphorus. With 1 ton of coffee bark combined with manure and some other fertilizers, farmers can produce 5m ³ of micro-organic fertilizer.

Up to now, farmers have popularized and replicated in the district many models of making coffee excrement effectively, especially models in difficult areas, ethnic minority areas . Currently many places. Phuong, the factory in Lam Dong province has also applied this measure.
