Ammonium sulfate 21-0-0 fertilizer is one of the first and most widely used nitrogen (N) fertilizers. It’s an important fertilizer that provides not only Nitrogen but also Sulfur (S). Sulfur supports or drives numerous essential plant functions. The optimal ratio of nitrogen and sulfur makes this fertilizer valuable for the growing needs of all plants including evergreens. The interaction of nitrogen and sulfur are both important in the chain of amino acid synthesis. In addition to providing nutrition with readily available sulfate sulfur and ammonium nitrogen to your plants, ammonium sulfate fertilizer assists plants with the uptake of other critical nutrients. In many soils, high soil pH decreases the solubility of phosphorus and critical micronutrients. When ammonium is absorbed by the crops, it acidifies their root zones, often unlocking phosphorus and key micronutrients such as zinc, boron, iron, copper, and manganese from fertilizers and soil. Ammonium sulfate is the best source of nitrogen for soil organisms. It activates the decomposition of plant remains. This increases the content of organic matter and soil humus, and it promotes the transformation and availability of other nutrients. Chemical formula: (NH4)₂SO₄ Nitrogen content: 21% Sulfur content: 24% Solution pH: 5 to 6. Ideal for Lawns, Azaleas, Blueberries.
