The treatments consisted of the application of
polymer-coated (PCU) and conventional urea (CU) as
maize topdressing. The coated and conventional
fertilizers contained 41 and 45 % N, respectively. The
coating of PCU consisted of compounds based on
polymers and minerals, forming a double membrane.
The polymer fraction was based on the association of
different polymers, resulting in different molecular
conformations after the final polymerization process
that occurs after applying the fertilizer coating
