Kri-Sop 0-0-50 (SOP) Water Soluble Fertilizer | Krishi Rasayan
Premium Potassium Sulphate for Maximum Fruit Size, Color, and Sugar Content.
Boost your harvest quality with Kri-Sop, a high-purity 100% water-soluble fertilizer from Krishi Rasayan. Unlike standard MOP, this sulphate-based formula (SOP) is free from harmful chlorides, making it the safest choice for sensitive high-value crops.
Best For: Increasing weight, shine, and taste in Grapes, Pomegranates, Bananas, and Vegetables.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Absorption: 100% water-soluble formula ensures nutrients are immediately available to the plant roots via drip or spray.
-
🛡️
Stress Tolerance: Hardens plants against drought, frost, and disease by regulating internal water pressure (turgor).
-
⏳
Superior Quality: Significantly improves fruit size, weight, uniform color, and shelf-life for higher market prices.
-
🌧️
Chloride-Free Safety: Ideal for saline soils and chloride-sensitive crops (like Tobacco and Grapes) where MOP causes burn.
-
🌿
Rich in Sulfur: Contains 17.5% Sulfur to boost protein synthesis, oil content in seeds, and overall greenness.

How It Works: Mode of Action
Kri-Sop works by delivering high concentrations of pure Potassium and Sulfur directly to the plant's metabolic system without adding harmful salts.
- Sugar Transport (The "Traffic Cop"): Potassium acts as a carrier, moving sugars produced in the leaves directly to the fruits and seeds, increasing bulk and sweetness.
- Enzyme Activation: It activates over 60 enzymes responsible for starch formation (vital for potatoes) and protein building.
- Water Regulation: It controls the opening and closing of leaf pores (stomata), helping the plant retain water during hot days.
This dual action ensures your crops finish strong with maximum marketable yield.
Target Crops & Benefits
| Crop | Target Benefit / Issue |
|---|---|
| Grapes & Pomegranate | Increases Brix (Sugar), improves color, prevents fruit cracking. |
| Potato & Tubers | Increases starch content, size, and specific gravity (crispiness). |
| Tomatoes & Vegetables | Ensures uniform red color, firmness, and longer transport life. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Apply primarily during the flowering and fruit-setting stages.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (Drip/Soil) | Water (L / Acre) | Dose (Foliar Spray) | PHI (Days) |
|---|---|---|---|---|
| Fruit Crops (Grapes, Banana) | 3 - 5 Kg / Acre | 200 Litres | 5 - 8 grams / Litre | 7 - 10 |
| Vegetables (Tomato, Potato) | 3 - 4 Kg / Acre | 150 - 200 Litres | 5 - 10 grams / Litre | 5 - 7 |
| Cotton & Cash Crops | 2 - 3 Kg / Acre | 200 Litres | 10 - 15 grams / Litre | 10 - 12 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
[Image of drip irrigation system]- Timing: Apply during the reproductive stage (from flowering until 15 days before harvest) for best results.
- Mixing (Crucial): NEVER mix Kri-Sop with Calcium Nitrate in the same tank. This causes clogging. Use separate tanks.
- Coverage: For foliar sprays, use a silicon-based spreader for better absorption on waxy leaves (like Onion or Citrus).
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the difference between Kri-Sop and MOP?
Kri-Sop (SOP) contains no chloride and has a low salt index, making it safer for quality fruits. MOP contains high chloride which can burn sensitive roots.
2. Can I use Kri-Sop for Hydroponics?
Yes! Kri-Sop is a standard source of Potassium for hydroponic and soilless culture due to its high purity and solubility.
3. Does it help in color development?
Absolutely. Potassium and Sulfur work together to synthesize anthocyanins (red pigments) and Lycopene, improving fruit color.
4. Can I mix it with other pesticides?
It is generally compatible with most pesticides. However, always perform a small "jar test" before mixing large quantities.
5. How to store the open bag?
Kri-Sop absorbs less moisture than other fertilizers, but you should still seal the bag tightly and store it in a dry place.
