Magnesium Sulphate Kieserite Green Granular
Product Features
1. Nutrient-Rich: 1.They primarily contain two secondary nutrients, sulfur and magnesium. Some products may also contain trace elements such as zinc, boron, and iron, meeting the diverse nutritional needs of crops. Sulfur is a crucial element for the synthesis of proteins, enzymes, and other substances in plants, while magnesium is the core atom of chlorophyll molecules and is crucial for photosynthesis.
2. Soil Improvement: 2.They can increase the presence of Thiobacillus in the soil, inhibit the activity of harmful bacteria, replace salt ions in the soil, reduce salt damage, and address soil acidification and salinization. Furthermore, as an acidic fertilizer, they balance soil pH, prevent soil compaction, and improve soil fertility and water retention.
3. Solubility: Magnesium sulphate fertilizer granules generally have high water solubility. The magnesium sulfate and sulfate ions in them dissolve quickly in water and are absorbed by crop roots, resulting in a high fertilizer utilization rate.
4. Long-lasting Fertilizer Effect:: 4.Some magnesium sulfate fertilizers utilize slow-release technology. This allows for a gradual release of nutrients, consistent with crop sulfur requirements, providing long-term, stable fertilizer effects.
5. Wide Applicability: 5.Suitable for various soil types and a wide range of crops, especially cash crops such as vegetables, fruit trees, tea, and flowers. It can improve crop quality and enhance their resistance to drought, cold, and pesticide damage.
Product Application and Effects
Cash Crops (vegetables, fruit trees, tea, etc.): For vegetables, apply 25-35 kg (approximately 1 acre) of base fertilizer, and apply 10-20 kg (approximately 1 acre) of topdressing 1-2 times during the growing season. For fruit trees (such as apples and citrus), apply 1-1.5 kg (apple saplings) per plant, and 2-3 kg (apple saplings) per plant (apple citrus). Application can be divided into two applications, before bud break and during fruit expansion. Ring furrow application is preferred.
Flowers/Nurses: Apply 5-10g of fertilizer per potted flower (20cm diameter) along the edge of the pot; apply 15-25kg per mu of nursery land, combined with irrigation.
Topdressing: Apply fertilizer in furrows or holes (5-10cm away from the crop root system to avoid root burn), or dissolve it in water (at a concentration of 0.2%-0.5%) and apply it by flushing or drip irrigation. This is especially suitable for crops with high water solubility requirements.
Precautions: Avoid mixing with alkaline fertilizers (such as wood ash or quicklime) to prevent reduced fertilizer efficiency. For sandy soils, apply small amounts in divided doses to minimize nutrient loss.
