Description

Product: Granular 21% Nitrogen Aquaculture Fertilizer Ammonium Sulfate

Molecular formula: (NH₄)₂SO₄

Description: Polymer coated fertilizer, also known as controlled-release fertilizer, is a type of fertilizer that has a polymer coating surrounding the granules. The coating is designed to slowly release the nutrients in the fertilizer over an extended period, instead of releasing all at once. This improves the efficiency of nutrient delivery to the plants and reduces the frequency of application.

The polymer coating is made of a blend of natural and synthetic polymers, which helps to regulate the release of nutrients gradually. The slow release of nutrients reduces the risk of burning the plants due to the excessive application of fertilizers. It also ensures that the plants receive a consistent supply of nutrients over a more extended period compared to conventional fertilizers.

Polymer coated fertilizers are commonly used in agriculture, horticulture, and landscaping. They are available in different formulations, such as granular or liquid, that are designed to meet the specific nutrient needs of different plants and crops. The use of polymer coated fertilizers has been shown to improve plant growth, increase yields, and reduce environmental pollution compared to conventional fertilizers.

However, it must be noted that ammonium sulfate cannot be mixed with lime to prevent the decomposition of nitrogen loss. Generally, the combined application of the two should be separated by 3~5 days.
