How is microbial activity measured on BiOWiSH® coated fertilizers?

To ensure success, we have proven our total Aerobic Plate Count (APC) minimum threshold in Colony Forming Units (CFU) along with a sound minimum fertilizer application rate per acre/hectare for BiOWiSH® coated fertilizers. The uniformity of coating by species has variability on each granule due to aspects like granule size differences and other factors. Agronomically, think of this akin to a blended NPK that has different N, P, and K components mixed together but not agglomerated into a single compound fertilizer. The NPK blend is applied/distributed across the field such that each individual nutrient component reaches the plants sufficiently to have the intended nutrient use effect and yield impact. This is similar to fertilizers coated with BiOWiSH® Crop Liquid, where exact CFU on each fertilizer granule is not critical so long as the right distribution of granules in the field is attained.
