The development of controlled- or slow-release fertilizers and fertilizers containing inhibitors, collectively referred to as enhanced efficiency fertilizers, has been pursued in recent decades. Goals for these products include synchronizing N availability with crop requirement, improving NUE, stabilizing crop yields, and decreasing N losses through NO 3 − leaching and N 2 O emissions.

Manufacturing of slow and controlled release fertilizer

· According to Ref. ; the slow release of fertilizers is generally classified into four types: (1) inorganic materials of low solubility, such as metal ammonium phosphates; (2) chemically or biologically degradable low solubility materials, such as urea-formaldehyde, (3) relatively soluble materials that gradually decompose in the soil, (4) water-soluble fertilizers controlled by a physical barrier, such as


A controlled-release fertiliser is a granulated fertiliser that releases nutrients gradually into the soil. Controlled-release fertilizer is also known as controlled-availability fertilizer, delayed-release fertilizer, metered-release fertilizer, or slow-acting fertilizer. Usually CRF refers to nitrogen-based fertilizers. Slow- and controlled-release involve only 0.15% of the fertilizer market.


This book is a revision of the IFA publication “Improving Fertilizer Use Efficiency: Controlled-Release and Stabilized Fertilizers in Agriculture” by the same author, published in 1997. It is intended for use by the fertilizer industry, policy makers and scientists. The main objectives of the book are to:

Controlled Release Nitrogen Fertilizers for Agriculture

release nitrogen fertilizers • Standard nitrogen fertilizers become 100% exposed to soil processes when appliedExamples include urea (46-0-0), ammonium sulfate (21-0-0), ammonium nitrate (34-0-0), and calcium nitrate (15.5-0-0) • Controlled release nitrogen fertilizers are standard granular fertilizers encased in a polymer coating

Synthesis and Application of Urea

Few studies have paid attention to high-concentration controlled release potassium (CRK) fertilizer because conventional potassium chloride (KCl) particles with the characteristics of irregular, high specific surface area, and bad fluidity are generally unsuitable to produce controlled-release fertilizer. The objective of this study was to investigate the interacting effects of urea

Manufacturing of slow and controlled release fertilizer

· Most of the commercial CRFs in the global market make use of this method in their production line with the total capacities of coated fertilizer estimated more than 3,000,000 tons in 2017 . The mechanism of nutrient release from the core to the environment is diffusion through the thin coating materials after being penetrated by water.
