Adopts encapsulated slow-release technology, coating magnesium sulfate heptahydrate with biodegradable polymers to achieve slow release of nutrients, avoiding nutrient loss of traditional fast-acting magnesium sulfate. The precisely proportioned magnesium and sulfur elements meet the nutritional demands of crop growth, adapting to a variety of cash crops such as vegetables, fruit trees and flowers. The breathable woven bag packaging facilitates field storage and spreading. Compared with traditional water-soluble magnesium sulfate, it has longer fertilizer efficiency duration, reduces fertilization times and lowers planting costs.
Detailed parameters include: available magnesium content ≥9.6%, available sulfur content ≥12.8%, particle diameter 1-3mm, moisture content ≤2.0%, nutrient slow-release period 60-90 days, packaged in 50kg polypropylene woven bags, complying with agricultural fertilizer packaging standards, shelf life of 36 months. Storage conditions: dry and ventilated place, avoid exposure to sunlight and rain. It can be used by spreading, drip irrigation or flush application.
Mainly used in vegetable planting (such as tomatoes, peppers, cucumbers), fruit tree planting (such as citrus, apples, grapes), flower horticulture and greenhouse crops, solving the problem of magnesium and sulfur deficiency caused by southern acidic soil and continuous cropping. It adapts to domestic agricultural resource dealers, family farms and large-scale planting bases, helping improve crop yield and quality, and improving fruit taste and color.
