The above chart demonstrates the Wolf Trax DDP unique Dual Action formulation.  Dual Action means that micronutrients are available immediately (60% more micronutrient to the plant than the untreated check at 7 DAE) and provide sustained feeding over time (4% more micronutrient to the plant than the untreated check at 28 DAE).  This was shown even under adverse soil conditions (soil pH of 8.2).
