- Abstract
Experimental formulations of a nitrogen-release fertilizer (urea) loaded into the polymer matrix prepared from degradable polyhydroxyalkanoates (films and pellets) have been developed and investigated. The use of the experimental formulation of urea reduces losses of the fertilizer compared to the use of its free form, i.e. the amounts of the fertilizer applied can be decreased. Degradation kinetics of the polymer matrix of the experimental formulation of urea enables urea release that provides the crops with sufficient amounts of nitrogen. Using these sustained release formulations, one can attain controlled targeted release of fertilizers throughout the plant growing season and reduce the amounts of the fertilizers applied.
