Potash mineral water-soluble chlorine-free fertilizer for basic, pre-sowing fertilizer application and for various crop and ornamental plants, grown in the open and protected ground on all soil types. Potassium sulfate is an ideal water-soluble source of potassium and sulfur for fruits, vegetables and flowers.
Recommended for cruciferous crops (leaf and cauliflower, broccoli, kohlrabi, watercress, spinach, Brussels sprouts, arugula, radishes, turnips or forage turnips, swede), vegetables (peppers, eggplant, tomato, cucumber, etc.) and just for solubilous crops: oilseed rape, sunflower, onion, garlic, etc. Highly effective for chlorine-sensitive crops: potatoes, tobacco, flax, grapes, citrus fruits, corn in the early stages of development, etc. It is used in drip irrigation for root feeding in protected and open ground and also as a component for the preparation of water-soluble NPP fertilizers and a liquid complex fertilizers. Potassium sulfate is also used for industrial purposes.
Do not mix with calcium nitrate (calcium nitrate).
The advantages of using potassium sulfate:
The product is packed in 25 kg polypropylene bags, soft containers up to 1000 kg.
Warranty period is 1 year from the date of manufacture of the product under conditions of transportation and storage.
Shelf life is unlimited.
|Dose of application||Mode of application|
