What are the advantages of slow and controlled release fertilizers? Which brand is better?

Thanks to their environmental friendliness and high utilization rate, slow and controlled release fertilizers have gradually been accepted and recognized by the vast number of farmers! Slow and controlled release fertilizers have advantages such as reducing the amount of fertilizer applied, saving raw materials for fertilizer production (coal, electricity, natural gas), improving fertilizer utilization rate, and reducing ecological and environmental pollution, so they are called “21st century high-tech environmentally friendly fertilizers” and have become the development direction of the fertilizer industry. So what advantages do slow and controlled release fertilizers have? Which brands of slow and controlled release fertilizers are more reassuring to use?

Slow release fertilizer refers to a new type of fertilizer that can delay or control the rate of nutrient release. Compared with quick-acting fertilizer, it has the following advantages:

1. It has low solubility in water, and nutrient elements are released slowly in the soil, reducing the loss of nutrient elements.

2. The fertilizer effect is long-lasting and stable, and it can continuously supply the plant's nutrient needs throughout the entire production period.

3. Because the fertilizer is released slowly, a large one-time application will not cause the soil salinity to be too high and “burn the seedlings”.

4. It reduces the amount and frequency of fertilization, saving costs.

At present, major fertilizer manufacturers basically all produce slow and controlled release fertilizers. Today, the editor will briefly introduce a few slow and controlled release fertilizer brands. The slow and controlled release fertilizers that are relatively reassuring to use at present include: the slow and controlled release fertilizer produced by Shandong Linyi Yufeng Fertilizer Industry, Jinyimeng slow and controlled release fertilizer, Bafute slow and controlled release fertilizer (zinc-boron-sulfur based), Luxi slow and controlled release fertilizer, Kingenta slow and controlled release fertilizer, Shikefeng slow and controlled release fertilizer, etc.
