TL;DR: The development of CRCU is a green technology that not only reduces nitrogen loss caused by volatilization and leaching, but also alters the kinetics of nitrogen release, which provides nutrients to plants at a pace that is more compatible with their metabolic needs.

TL;DR: Urea coated by modified-starch was double coated by a geopolymer to enhance the controlled release characteristics that produced promising results with respect to the longevity of nitrogen release from the final product.

TL;DR: In this paper, a multi-diffusion model that simulates nitrogen release from coated urea particles for both the constant and decay release stages of urea is proposed, which is developed for multilayer included the coating and water zone, and integrates a Finite Element Method (FEM) with 2D geometry to enhance the accuracy of simulation by introducing urea diffusivity in water domain as a function of its concentration.

TL;DR: In this article, the effect of coating thickness on release time and diffusion coefficient of urea release in distilled water was investigated and it was concluded that a significant coating thickness in addition to good uniformity of thickness and film integrity can produce promising controlled release characteristics.

TL;DR: In this article, the authors proposed a porous model that couples the interfacial area ratio (IAR) equation for the diffusion of nitrogen with mass transport equation in porous medium (soil).
