Ammonium Sulfate ((NH₄)₂SO₄) from MaxStone is a premium nitrogen fertilizer and herbicide adjuvant, enriched with 21% nitrogen (N) and 24% sulfur (S), designed to enhance plant growth and improve crop yields. This product adheres to ISO 9001:2015 and GMP standards, ensuring top-quality production and reliability. It features a maximum moisture content of 0.05%, free acid at approximately 5%, and an arsenic (As) level of ≤ 0.001%, making it a safe and effective choice for agricultural use. The fertilizer comes in two convenient sizes: 50kg and 25kg bags, catering to a variety of farming needs.
For optimal use, the recommended application rates are 300-400 kg per hectare for crops, 1 kg per tree at the beginning of spring for fruit trees, and 15 grams per plant for greenhouse cultivation. However, the exact amount required for rapid growth depends on the type and age of the plants, as well as climatic conditions. For best results, it is advised to conduct a soil analysis and consult an expert supervision method before application. The product should be stored in a cool, dry place in its original packaging, away from humidity and out of reach of children, to maintain its efficacy.
Beyond its core specifications, Ammonium Sulfate serves as a dual-purpose product, providing essential nutrients while acting as an adjuvant to enhance the effectiveness of herbicides. The nitrogen content promotes vigorous vegetative growth, strengthens plant stems, and boosts protein synthesis, making it ideal for a wide range of crops including cereals, vegetables, and fruits. The sulfur component aids in the synthesis of amino acids and vitamins, improving crop quality and resistance to environmental stress. As a herbicide adjuvant, it improves the penetration and absorption of weed control agents, ensuring more effective weed management. This versatile fertilizer supports sustainable farming practices by reducing the need for multiple applications and enhancing overall soil health. Its high solubility ensures quick nutrient availability to plants, while its durable packaging facilitates easy handling and storage, making it a practical choice for farmers seeking to optimize their agricultural output.
