Implementation
The fertiliser is administered either by topdressing the soil, or by mixing the fertiliser into the soil before sowing. Polymer coating of fertilizer ingredients gives tablets and spikes a 'true time-release' or 'staged nutrient release' (SNR) of fertilizer nutrients. NBPT functions as an inhibitor of the enzyme urease. Urease inhibitors, at levels of 0.05 weight percent, are added to urea-based fertilizers to control its conversion to ammonia.
