Each contains billions of live bacteria that are essential in the nitrogen fixating process of garden legume plants. These bacteria, when properly placed in the root zone area of the soil, will actively convert atmospheric nitrogen into a useable form for the plant. Therefore, enabling the plant to produce its own organic source of nitrogen, leading to more lush vine growth and ultimately greater yields. Apply using slurry mix as in Exceed above.
