Adopts coated slow-release technology, wrapping magnesium sulfate particles with controllably degradable biological membranes, avoiding rapid nutrient loss and soil fixation. Compared with ordinary magnesium sulfate fertilizers, the nutrient utilization rate is increased by more than 40%, suitable for alkaline soil use to adjust the soil microenvironment, heavy metal residues, and soil aggregate structure. It solves the pain points of rapid nutrient loss and short fertilizer effect of ordinary magnesium sulfate fertilizers.
The appearance is gray uniform particles, with available magnesium nutrient (MgO) ≥16.0%, available sulfur (S) ≥13.0%, 90% of which is between 2mm and 4mm, moisture content ≤2.0%, pH value 6.0-7.5, slow-release period 60-90 days, nutrient release rate ≥20% in 7 days, ≥60% in 30 days, and the packaging is 50kg PP woven bags, complying with NY 1107-2010 water-soluble fertilizer standards.
It is suitable for field crops such as rice, wheat and corn, cash crops such as tomatoes, citrus and grapes, top dressing and base fertilizer for potted flowers and horticultural plants. It can be applied by spreading, drip irrigation, flushing and other methods, improving the yellowing and magnesium deficiency symptoms of crops, and enhancing fruit sweetness and color.
