5.4 Conclusions
The controlled release system allows for the controlled delivery, over time, of
various agrochemicals that maintain their activity through a desired time period
in the soil while reducing the quantity of the agrochemical that was applied, the
manpower, and the energy or combustive necessary to operate the application
devices. The use of nanotechnology in the agriculture field provided advantages
when compared to use of materials from the macroscopic scale, improving mainly
crop productivity and protection. There is currently little existing information about
the controlled release of agrochemicals from nanostructured materials. Our
research group is focused on understanding the controlled release of NPK fertilizers
and pesticides from hydrogel nanocomposites that are based on polysaccharide and
silicate nanostructured-like zeolites and nanoclays.
