ICL Select SOP is a fully water-soluble potassium sulphate fertilizer used when crops need strong potassium and sulphur nutrition. Select SOP 0-0-50 + 17.5S fertilizer is nitrogen-free, so it is useful during fruit development, ripening, quality-building, and maturity stages. ICL Select SOP helps improve fruit size, colour, sweetness, firmness, shine, and overall produce quality when used at the right crop stage. Select SOP also supports sulphur nutrition, which helps in protein formation, enzyme activity, and crop strength. The Select SOP fertilizer is suitable for fruits, vegetables, flowers, field crops, and protected cultivation crops.
Key Features and Benefits of ICL Select SOP:

ICL Select SOP Dose:
ICL Select SOP Dose Per Litre for stock solution preparation is about 70 to 100 g per litre, based on 7 to 10 kg in 100 litres of water. For field application, Select SOP 0-0-50 + 17.5S fertilizer is generally used at 15 to 25 kg per acre through fertigation, adjusted as per crop stage, soil condition, water quality, and local agronomy guidance.
Crop | Target Purpose | Dose per acre | Application Method |
|---|
Fruit Crops | Fruit size, colour, sweetness, firmness, and maturity | 15 to 25 kg | Fertigation or drip irrigation |
Vegetables | Fruit filling, quality, potassium support, and crop finishing | 15 to 25 kg | Fertigation or drip irrigation |
Flowers | Plant strength, bloom quality, and potassium nutrition | 15 to 25 kg | Fertigation or drip irrigation |
Field Crops | Crop maturity, sulphur support, and potassium nutrition | 15 to 25 kg | Fertigation or soil-water application |
Protected Cultivation Crops | Quality improvement and nutrient balance | 15 to 25 kg or as per system plan | Hydroponics or fertigation |
Plantation Crops | Potassium and sulphur support during active growth | As per crop age and canopy | Drip or fertigation |
How to Use ICL Select SOP:
Measure the required quantity of ICL Select SOP as per crop stage and fertilizer plan.
Use clean water for dissolving Select SOP 0-0-50 + 17.5S fertilizer.
Add ICL Select SOP slowly into the water while stirring.
Mix until Select SOP dissolves fully and no particles remain at the bottom.
For fertigation, apply the prepared solution through drip or irrigation system.
Flush the irrigation system with clean water after fertigation.
Do not mix ICL Select SOP with calcium-based fertilizers in the same tank.
Avoid using Select SOP in water with very high calcium without guidance.
Use Select SOP 0-0-50 + 17.5S fertilizer during potassium-demand stages like fruit development and maturity.
Avoid overdose because excess fertilizer can stress crops and disturb nutrient balance.
Follow local soil test, water test, and crop-stage guidance for best results.
Best Time to Apply:
Apply ICL Select SOP when the crop needs higher potassium, especially during fruit development, fruit filling, ripening, tuber development, grain filling, or crop maturity. Select SOP 0-0-50 + 17.5S fertilizer is also useful when crops need sulphur support along with potassium. ICL Select SOP gives better results when the crop has proper moisture and active roots. Avoid using Select SOP on severely stressed, waterlogged, or weak crops without correcting field conditions first.
Frequency of Application and Re-Entry Period:
Frequency of Application: Apply ICL Select SOP based on crop stage, fertigation schedule, and nutrient demand. Repeat only as per crop requirement and local agronomy advice.
Re-Entry Period: Normal field entry can be followed after fertigation. For foliar use, avoid entering the sprayed field until the crop dries or use protective gear.
Compatibility: Select SOP 0-0-50 + 17.5S fertilizer should not be mixed in the same tank with calcium fertilizers. Always do a jar test before mixing with other inputs.
Application Care: ICL Select SOP should be fully dissolved before fertigation to avoid blockage in drip lines or filters.
Crop Condition: Select SOP performs better in healthy crops with proper irrigation, balanced base nutrition, and good root activity.
