Age Old Commercial Base is designed to deliver the right amount of nutrients at the right stage of the crop, and is designed to be used during both the vegetative and reproductive stages of the crop. It efficiently delivers nitrogen (N), phosphate (P), potassium (K), boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn). All of the micronutrients are chelated or micronized to ensure they remain available to the plant regardless of the soil pH. In addition to this, all of the inputs are tested for heavy metals to ensure that only the purest minerals are sourced. Finally, Commercial Base is blended and micronized to ensure that it enters into solution without any issue.
