Simple method to obtaining a prolonged-release system of urea based on wheat gluten: development and characterization

Urea is one of the most widely used nitrogen fertilizers. However, it is lost to the environment via processes such as denitrification, surface runoff, volatilization, and leaching. In this paper, a novel material is reported on, with low production cost and avoiding the use of harmful solvents, with a pastille morphology developed by a simple method from a mixture of wheat gluten and urea, with potential use as a prolonged-release system of...
