Evaluation of Eximo plus Dispatch for reduction of sodium in USGA specification greens
Summary: The results show that Aquatrol's Eximo (a synthetic acid), in combination with Dispatch (a surfactant) had no impact on levels of calcium, sodium, or bicarbonate (measured using Mehlich 3 or saturated paste methods) in the soil. The test, however, was conducted on soils that were low (less than 5%) in calcium carbonate. According to Aquatrols representatives, the product's efficacy relies on the presence of calcium carbonate in the soil.
Therefore, in soils that are low in calcium carbonate, Eximo does not appear to have any positive impact on soil chemistry. The performance of this product in soils with significant calcium carbonate levels remains to be seen.
