USE OF AGRICULTURAL BY-PRODUCTS IN MAKING BIOCHAR OR A STORY FROM A GINEARD
I thought that the story of improving land was the work of the agricultural industry and had little to do with the energy industry. But "Research on utilizing green waste (vine stems, branches and manure) to produce biochar for soil improvement and towards saving energy for irrigation in hilly grape farming areas in Thu Cuc commune, Tan Son district, Phu Tho province" conducted by the University of Natural Sciences (VNU) has proven the opposite.
To carry out the research, the team of officials selected a sample of grape growing land that had been improved from land used to grow perennial crops (tea trees) that had been barren and degraded, and invested in many potential facilities in the future. culture. With the local grape cultivation development process being increasingly stable, the potential for producing materials from vineyard by-products (biochar) is very positive. With the anaerobic heating method, the biochar material produced still retains its morphology, reducing ashing. From there, ensure the nutritional content of the material.
Research staff collected soil samples
In addition, experiments adding biochar to grape soil also showed high effectiveness in improving soil properties and structure. Especially adding an abundant amount of organic matter to the soil thereby improving soil quality.
Soil samples were collected for research
The results of this research show that agricultural by-products (such as vineyards) are not only used to make biological materials but also continue to "enrich" the soil. From there, it helps save energy in irrigation and cultivation but also uses natural energy to cycle back to serve nature.
