Potassium plays a crucial role in photosynthesis processes, enzymatic activities, preventing water stress, the opening and closing of stomata, sugar transport, starch production, and nutrient transfer from leaves to fruits. Potassium deficiency in plants first appears in older leaves as browning and tip burn, incomplete fruit development, and sensitivity to various stresses. The best time to apply potassium-containing fertilizers is at the end of the season, during grain filling in cereals, and during fruit ripening. One of the most important and classic high-potassium fertilizers among farmers is potassium sulfate.
Green World Potassium Sulfate contains 50% water-soluble potassium and 17.5% soluble sulfur, is fully water-soluble, and is one of the most renowned potassium fertilizers in agriculture and horticulture. This fertilizer is used in field crops from formation to maturity and in fruit trees and vegetables after fruit set, as it provides high levels of quality potassium and is the best fertilizer for the crop ripening stage. It supplies potassium and sulfur without chloride. Due to its sulfate content, it lowers soil pH, improving the uptake of elements like iron and phosphorus. Do not mix this fertilizer with calcium- or copper-containing compounds. For optimal results in crops like wheat, corn, cotton, and alfalfa, apply it during early growth stages and throughout the ripening period.
Field crops and fruit trees: 10-15 kg per hectare (fertigation)

Always read the label and product information before use. Follow these guidelines to ensure safe handling and application:
Handling: Wear protective gloves, long sleeves, and eye protection during mixing and application to avoid skin or eye irritation. Potassium sulfate is non-toxic but can cause mild irritation.
Storage: Keep in a cool, dry place away from moisture, children, pets, and food. Store sealed in original 10kg bags to prevent clumping.
Mixing: Never mix with calcium (e.g., gypsum, lime) or copper-based products, as it may cause precipitation or reduced efficacy. Test compatibility on a small scale first.
Application: Apply only during recommended stages (early growth to ripening). Avoid overuse to prevent nutrient imbalance. For fertigation: 10-15 kg/ha; foliar: 2-3 kg/ha diluted in sufficient water.
First Aid: If inhaled, move to fresh air. For skin/eye contact, rinse with plenty of water for 15 minutes. Seek medical advice if irritation persists. Ingestion: Do not induce vomiting; rinse mouth and drink water.
Disposal: Dispose of empty bags responsibly per local regulations; do not reuse for food storage.

Soil Health: Lowers soil pH slightly via sulfate, boosting iron and phosphorus availability without acidification risks. Chloride-free formula prevents soil salinization in sensitive crops.
Water Quality: Fully water-soluble; minimal residue in runoff if applied at recommended rates. Avoid application before heavy rain to reduce leaching.
Wildlife and Pollinators: Non-toxic to bees, birds, and aquatic life at field rates. Enhances plant stress tolerance, reducing need for irrigation and indirectly conserving water.
Best Practices: Use precision fertigation to minimize excess. Integrate with soil testing for balanced nutrition. Supports organic-like farming by improving natural nutrient cycles.
