Roots are the digestive system of plants. The more root surface there is, the more nutrients the plant can take up. This translates to more yield potential. Roots are all about surface area. For example, phosphorus is an important nutrient, but it is very immobile in soils. The Bio-Gro system has shown to significantly increase the root to soil contact (more roots, more fine root hairs), which in turn, increases the uptake of phosphate!
