1、A Review and Perspective on Slow and Controlled Release Fertilizer in China

Based on the study of slow and controlled release fertilizer, we summarized a large number of research materials at home and abroad, comprehensive elaborated the development progress of slow and controlled release fertilizer in China, and reviewed the utilization efficiency of fertilizer in different corps.

2、Innovative use of controlled availability fertilizers with high performance for intensive agriculture and environmental conservation

A variety of slow release fertilizers, controlled release (availability) fertilizers (CAFs), and stability fertilizers have been developed in response to the serious drawbacks of the conventional fertilizers since the early 1960’s.

Here, we conducted field experiments to identify the effects of a single application of controlled-release urea (CRU), conventional urea (CU), and chicken manure (CM) on N losses and yields improvement in a greenhouse tomato system in Beijing, China.

4、Research and Development of Controlled

The use of controlled release fertilizers (CRFs) has been recognized as an efficient approach to nutrient management in China since 1997, but a critical review of the country’s CRF research and development (R&D) is lacking.

USE OF CONTROLLED

Slow and controlled release fertilizers contain nutrients in a form which delays its availability for crops or extends its availability to crops longer than the conventional soluble fertilizer.

Thermal post

Controlled-release fertilizers (CRF) use a controlled-release technology to enhance the nutrient use efficiency of crops. Many factors affect the release of nutrients from the waterborne...

Controlled release NPK compound fertilizer with the function of water retention

Controlled release nitrogen, phosphorus and potassium (CRNPK) compound fertilizer with the function of water retention was prepared, which possessed the core/shell structure.

Effects of Controlled

Compared to liquid fertilizer (LF), which is commonly used in soilless cultures, controlled-release fertilizer (CRF) is simple and economical because it does not require equipment to adjust nutrient concentration and fertilizer delivery.

Effect of controlled

A 3-year field experiment was carried out in a tea field in southern China from January 2014 to December 2016 to investigate the effect of controlled-release fertilizer (CRF) application on N 2 O emissions in tea field system.

A Rapid Technique for Prediction of Nutrient Release from Polymer Coated Controlled Release Fertilizers

Controlled release fertilizers (CRF) are produced with different rates and durations of nutrient release to cater to dif-ferent crops with wide ranges of nutrient requirements. A rapid technique is needed to verify the label specifications of nutrient release rate and duration.

As a frontier city of China's reform and opening-up, Shenzhen boasts advanced agricultural modernization and technology application. In agricultural production, controlled-release fertilizers—known for their efficiency and environmental friendliness—have gained widespread attention and adoption.
