PROTOPHOS 14-54 is a balanced fusion of phosphates with two forms of nitrogen. The phosphates are linked, by means of proton activity, to ureic nitrogen forming an adduct and, by ionic bonds to ammonium ions. The resultant formulation minimises the loss of nitrogen from the soil in two ways: i) by reducing volatilisation to the atmosphere; ii) by an acidifying effect which deactivates urease enzyme in the soil, slowing down the degradation of urea by hydrolysis. This is particularly beneficial in calcareous soils. Other significant benefits of using PROTOPHOS 14-54 are: a) The low pH (2.5 in a 0,1% solution) aids in the release of icronutrients from the soil. b) This acidity ensures that irrigation systems are kept free of calcium deposits, even in hard water areas. Pipes and nozzles remain lockage-free and there is no need to use hazardous acids for cleaning.
