Potassium acid Mannheim method Potash fertilizer 50kg/pack Shipment Sichuan
The full name of this product is "Mannheim Method Potassium Sulfate", a high-quality chlorine-free potassium fertilizer with potassium sulfate (K₂SO₄) as the main component, produced by the Mannheim Process. It is packaged in 50kg bags and mainly shipped from factories or warehousing centers in Sichuan Province. As one of China's important production bases for Mannheim Method potassium sulfate, Sichuan relies on local abundant sulfur resources and a mature chemical industry chain to ensure the stable supply of high-quality potassium sulfate.
1. Core Advantages of the Mannheim Process
The Mannheim Process is a classic technology that produces potassium sulfate by reacting potassium chloride with concentrated sulfuric acid in a rotary kiln through high-temperature solid-phase reaction. Its product advantages are significant:
Ultra-High Purity: The chloride ion (Cl⁻) content in the finished product is usually below 1.5%, much lower than the national standard, making it a high-quality chlorine-free potassium fertilizer.
Dual Nutrient Supply: In addition to providing high-concentration potassium (K₂O ≥ 50%), it also contains about 17-18% sulfur (S) element, meeting crops' demand for the secondary element sulfur.
Stable Crystal Structure: Produces dense crystals or granules with high hardness, not easy to pulverize, fully water-soluble with no residues, facilitating mechanized application and long-distance transportation.
2. Key Physicochemical Indicators and Applicable Standards
Potassium Oxide (K₂O) Content: First-class products are usually ≥52.0%, and qualified products are ≥50.0% (implementing GB/T 20406-2017).
Chloride Ion (Cl⁻) Content: Generally ≤1.5%, and some high-end products can be ≤0.5%.
Moisture: ≤0.5%, not easy to cake.
pH Value: Weakly acidic, suitable for most soils, especially for improving alkaline soils.
3. Core Agronomic Value and Application Scenarios
Core Fertilizer for Improving Crop Quality:
Crucial for quality improvement of chlorine-intolerant crops: Significantly improves the combustibility of tobacco, starch content of tubers, sugar content and color of fruits, and aromatic components of tea.
Enhances crop stress resistance: Promotes cellulose synthesis, strengthening resistance to lodging, cold, drought, and diseases.
Irreplaceable Application Scenarios:
Chlorine-Intolerant Cash Crops: Tobacco, potatoes, citrus, grapes, watermelons, tea trees, coffee, peppers, etc.
Saline-Alkali Soils and Protected Agriculture: Chlorine-free property avoids soil salt accumulation, protecting root health.
High-Quality Water-Fertilizer Integration Systems: Fully water-soluble with low impurities, an ideal potassium source for high-end water-soluble fertilizers in drip irrigation/sprinkler irrigation.
Adaptability to Southwest Regional Planting:
Shipment from Sichuan can efficiently radiate the advantageous areas of characteristic cash crops in southwest China (Yunnan, Guizhou, Sichuan), meeting the demand for high-quality potassium fertilizer in industries such as tobacco, Chinese medicinal materials, alpine vegetables, and premium fruits.
4. Supply Chain Advantages of "Shipped from Sichuan"
Direct Supply from Origin with Controllable Costs: Relies on local production capacity in Sichuan, reducing intermediate turnover and ensuring price competitiveness.
Mature Logistics Network: As a transportation hub in southwest China, Sichuan can efficiently cover the whole country through railways and highways, especially with strong delivery timeliness to the southwest, central China, and northwest regions.
Stable Supply: Localized production reduces the risk of supply disruption caused by weather, transportation, and other factors, supporting large-scale procurement during peak seasons.
