Sustainable Bio-fertilizers are cutting edge technology. High-tech should always be so  simple and uncomplicated.Biofertilizers (also known as “plant-growth promoting rhizobacteria” or PGPR) have come on rapidly in “sustainable” agricultural circles, providing eco-friendly organic agro-input. A biofertilizer contains living microorganisms which, when inoculated into biochar or soil, promotes growth by increasing the supply or availability of major nutrients, such as Nitrogen and Phosphorus. Bio-fertilizers add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth-promoting bacterial bio-liquides. Bio-fertilizers do not contain any chemicals.

Using Biochar in conjunction with aquaponics is a cutting edge innovation. Biochar has proven to be many times more useful as a medium than rocks. This is true especially when considering applications and/or inoculations with beneficial microorganisms. This is mainly due to the porous structure of Biochar which supports microbial communities.

Due to immobilization of phosphate by mineral ions such as Fe, Al and Ca or organic acids, the rate of available phosphate (Pi) is always below plant needs. In addition, chemical Pi fertilizers are also immobilized in the soil, immediately, so that less than 20 percent of added fertilizer is absorbed by plants. Therefore, reduction in Pi resources, on one hand, and environmental pollutions resulting from both production and applications of chemical Pi fertilizer, on the other hand, have already demanded the use of new generation of phosphate fertilizers globally known as phosphate-solubilizing bacteria or phosphate bio-fertilizers.
