1、Controlled

Abstract se inhibitors and stabilized fertilizers. Controlled-release ertilizers are generally coated products. Slow-release fertilizers are noncoated products in which the nutrient release is uncontrolled but slow; these are mainly urea-aldehyde reaction products but also include other slowly soluble products such as fertilizer

2、Controlled release fertilizer: A review on developments, applications

Currently, there are two types of advanced fertilizers for the purpose of precision agriculture: (i) slow-release fertilizers (SRF), and (ii) controlled release fertilizers (CRF).

3、Slow and controlled release fertilizer

Slow and Controlled-release fertilizer is a new type of fertilizer that controls the release of nutrient elements through physical or chemical means to meet the nutritional needs of plants and minimize nutrient loss as much as possible.

4、Market Prospect of Slow Release Fertilizer in China

Slow/controlled release fertilizer can produce the same yield with the rate 10-40% less than conventional fertilizer. Sometimes, only single application is required, which can reduce labor cost by 75%.

5、Slow and controlled release nanofertilizers as an efficient tool for

Therefore, this review article provides insights into slow and controlled release nanofertilizers, including preparation approaches, nutrient-release techniques, analytical detection methods, current status, role in crop improvement, commercial viability, and future perspectives.

Manufacturing of slow and controlled release fertilizer

The scope of this chapter is focused on the commercial production of the slow and controlled release fertilizer using the encapsulation and hydrophobic methods.

Characteristics and types of slow

Slow- and controlled-release fertilizers (S/CRFs) are considered as novel and revolutionary approaches in the field of fertilizer synthesis. S/CRFs are seen as economical and environment-friendly alternative to chemical fertilizers.

Their use features numerous advantages in terms of significant savings of fertilizers' inputs, labour, energy and time. They favour increased water-use efficiency and markedly reduce the chemical...

Slow

The two most important groups of slow- and controlled-release fertilizers, according to their production process are: condensation products of urea-aldehydes (slow-release fertilizers), and coated or encapsulated fertilizers (controlled-release fertilizers). Supergranules and others are of lesser or only regional importance.

Controlled

CRF not only prevents nutrient loss but also ensures a customized nutrient release pattern that aligns with plant physiological and biochemical processes. Despite these advantages, CRF has yet to find extensive adoption in the commercial agricultural practices.
