UREA AL.FE is the most widespread and used nitrogen fertilizer in the world. With a 46% Nitrogen content, it is also the most concentrated fertilizer.
UREA, once distributed on the soil, is transformed first into ammonia salts and then into nitrates.
This double reaction makes the compound progressive and gradual in its activity, simultaneously providing crops with quick-acting nutrients (nitrates) and reserve nutrients (ammonia salts) that are difficult to wash away.
