Controlled release fertilizer

What is controlled-release fertilizer?

Controlled-release fertilizer is to delay the initial release of nutrients by various regulatory mechanisms, and control the release amount and speed of nutrients according to the needs of crops, so as to keep the release of nutrients in fertilizer consistent with the needs of crops, so as to achieve the purpose of improving the efficiency of fertilizer.At present, the common controlled-release fertilizer is enveloped fertilizer, that is, a film is spread on the outside of the traditional quick-acting fertilizer, and the rate of diffusion of nutrients in the film to the outside of the film is controlled through the microholes on the film, so that the release film type (release rate and continuous effective release time) is synchronized with the absorption of nutrients in crops according to the set release film type.

Benefits

Ø Complete nutrition, polymer coated, long-lasting slow release time, product performance independent of temperature.

Ø Plant resin coated, effective controlled release period is 3-12 months, continuous and uniform release of nutrients, high absorption rate, no root burning.

Ø Economic and environmental protection, fertilizer utilization rate of more than 70%, reduce the number of times and amount of fertilizer, reduce the cost of fertilization by more than 1/3.

Ø Effect of temperature on Fertilizer efficiency period (higher ambient temperature, faster release).

Ø It is suitable for the nutritional supplement of plants during the growth, flowering and post-flowering period.

Application

Degradable polymer resin coating, combined with slow-acting components, can continuously and stably release nutrients. Its nutrient release rate is only affected by temperature.And add magnesium, iron and other trace elements, promote the synthesis of chlorophyll and enhance photosynthesis, so that the plant leaves dark green, robust growth.

Long fertilization effect, one fertilization effect as long as 90-360days, reduce fertilization times, save labor costs.

Good sex and the presence of slow-release ingredients greatly reduce the risk of burning roots and seedlings

High utilization rate, reduced leaching and volatilization loss of fertilizer, nutrients can be effectively absorbed by plants, improve fertilizer utilization rate, and reduce environmental pollution.

High cost performance. The reduction of labor cost and the improvement of fertilizer utilization rate and crop quality make the cost performance of slow-release fertilizers higher than that of traditional fertilizers.
