DEVELOPMENT OF A BIOFUNCTIONALIZED HUMIC-LOADED FLY ASH AMENDMENT FOR IMPROVING SOIL HEALTH

The intensive industrial and power sectors generate huge amounts of diverse wastes which have detrimental consequences for the environment if not properly managed. Fly ash is one most complex abundant anthropogenic has traditionally been considered as highly problematic treatment disposal. Being dumped on indigenous community lands, FA-wastes block their usage contaminate terrestrial aquatic ecosystems. These processes lead to chronic pollution degradation waters, soils, air. Our previous pilot studies implied that addition coal-derived substances soil help improve physicochemical biological properties stimulating plant growth enhancing crop yield. main advantage FA compared many other inorganic amendments it can be easily engineeringly optimized due its precisely characterized chemical composition, a specific combination surface properties, hierarchical porosity. use beneficial microorganisms well HA in with potentially stimulate production through biofertilization mechanisms, including nitrogen fixation, phosphate solubilization, phytohormone production, biocontrol processes. Thus, PGPR key factor maintaining fertility candidate FA-HA composite engineering co-inoculation could an excellent application. aim proposed research develop technology efficient biotechnological fertilizer new-generation – FA-HA-PGPR. Synthesis novel fertilizers by used farmyard manure, digestate, compost, sludge very promising potential. However, ecological biogeological behavior yet adequately studied. Engineering quality FA-based products requires determination nutrient release characteristics detailed examination performance various types agroecological conditions. As result, FA-HA-PGPR will engineered functionalized new fertilizer.
