Fertilizer Coatings & Additives
ImPhos is a liquid additive specifically formulated to impregnate dry Phosphorus (MAP, DAP, ...) in order to prevent its tie-up with Ca2+ (calcareous soils), Fe2+ and Al3+ (acidic soils). It has been formulated in a highly concentrated form to be applied at low volume on dry fertilizer, enhancing drying time and reducing chances for caking. Once applied to the soil, the impregnated Phosphorus is protected in a readily available form for a period of 100-150 days, depending on the moisture and temperature conditions.
ImPhos is recommended at a rate of 0.5-1.0 L per acre with the starter fertilizer and 3.0L/ metric ton of dry fertilizer.
TPA is a liquid additive intended to be used with the liquid starter fertilizer (Ortho P, 10-34-0) or to impregnate dry Phosphorus (MAP, DAP, ...). TPA enhances nutrient availability and maximizes Phosphorus use efficiency. In addition, the negatively charged molecule reduces Phosphorus tie-up with Ca2+ (calcareous soils) or Fe2+/Al3+ (acidic soils). TPA provides 10% of Potassium that triggers the release of additional Potassium from the clay layers and is biodegradable, preventing the accumulation of any residuals over time.
TPA is recommended at a rate of 0.5-1.0 L per acre with the starter fertilizer and 3.0L/ metric ton of dry fertilizer.
