Bacta-Mix is a soil activator - organic fertilizer in the form of water soluble powder which contains spores of beneficial soil bacteria. The role of these bacteria in the soil is versatile. Bacilli Βacillus pumilis, Βacillus subtilis, Βacillus licheniformis, Βacillus megaterium produce auxins and other phytohormones that help in the creation of a large and dense tassel in the root. The strain Bacillus Megaterium vP produces substances which dissolve the insoluble in the water soil phosphorus by converting it into forms easily assimilated by plants. Azotobacter bacteria bind atmospheric nitrogen and release it in the form of ions that is later converted in nitrate form and absorbed by plants.
