Role of Potassium in Crops
Potassium is one of the three primary plant nutrients and plays an important role in water regulation, enzyme activation, photosynthesis, carbohydrate movement and overall crop metabolism.
During flowering and fruit development, crops often require increased potassium availability. Adequate potassium nutrition can support the movement of carbohydrates toward developing fruits, tubers, bulbs and other harvested plant parts.
Role of Sulphur in Plant Nutrition
Sulphur is an essential secondary nutrient required for the formation of important amino acids, proteins and enzymes. It also supports chlorophyll formation and several metabolic processes associated with healthy crop growth.
Solfert Ultimate provides both potassium and sulphur, allowing farmers to supplement these nutrients during important crop-development stages.
Recommended Crops
Mahindra Summit Solfert Ultimate can be used in label-recommended crops where supplemental potassium and sulphur nutrition is required, including:
- Tomato
- Chilli
- Brinjal
- Cucumber
- Onion
- Potato
- Other vegetable crops
- Fruit crops
- Flower crops
- Other high-value crops requiring potassium nutrition
Recommended Application Stage
Solfert Ultimate is particularly recommended during the fruiting stage, when potassium demand increases for fruit enlargement, quality development, carbohydrate movement and crop maturation.
It may also be incorporated into a balanced crop nutrition program during flowering and other growth stages based on crop requirement, soil fertility and plant nutrient status.
Dosage and Application
| Application Method | Recommended Dose |
|---|---|
| Foliar Spray | 5 g per litre of water |
| Drip / Fertigation | 7.5–12.5 kg per hectare |
The drip recommendation is equivalent to approximately 3–5 kg per acre. Final dosage should be adjusted according to crop stage, soil fertility, irrigation system and crop-specific nutrient requirements.
Foliar Spray Application
For foliar application, dissolve approximately 5 g of Solfert Ultimate per litre of clean water and spray uniformly over the crop foliage.
Ensure adequate coverage while avoiding excessive runoff. Foliar spraying is best carried out during cooler parts of the day such as morning or late afternoon.
Drip and Fertigation Application
For drip irrigation or fertigation, Mahindra Summit recommends approximately 7.5–12.5 kg per hectare, depending on crop requirement and cultivation conditions.
Dissolve the required quantity completely before introducing it into the fertigation system. Ensure that filters, irrigation lines and emitters are functioning properly.
How Solfert Ultimate Works
After application, potassium becomes available to support several important physiological functions within the plant. It helps regulate water movement, stomatal activity, carbohydrate transport and enzyme activation.
Sulphur supports protein synthesis and other metabolic functions. Together, these nutrients help support crop development during high-demand stages such as flowering, fruit filling and maturation.
Solfert Ultimate for Fruit Development
Potassium plays an important role in moving sugars and carbohydrates from leaves toward developing fruits and other storage organs. Adequate potassium availability can therefore help support proper fruit filling, size and quality.
Application during the fruiting stage can be particularly useful in fruiting vegetables and horticultural crops with high potassium requirements.
Solfert Ultimate for Produce Quality
Balanced potassium nutrition helps support produce characteristics such as size, colour, firmness and overall market quality. It also contributes to water regulation within plant tissues and can support better post-harvest performance.
Chloride-Free Potassium Nutrition
Solfert Ultimate is based on potassium sulphate and provides a chloride-free potassium source. This characteristic can be useful for crops that are sensitive to excessive chloride accumulation.
Its potassium sulphate base also provides sulphur in addition to potassium, making it suitable for high-value crop nutrition programs.
How to Use Mahindra Summit Solfert Ultimate
- Identify the crop growth stage and potassium requirement.
- Select the appropriate foliar or fertigation application method.
- Measure the recommended quantity accurately.
- Dissolve the fertilizer completely in clean water.
- For foliar use, spray uniformly over healthy foliage.
- For fertigation, introduce the dissolved fertilizer gradually through the irrigation system.
- Flush irrigation lines with clean water after fertigation where required.
- Integrate the product with a balanced crop nutrition program.
Best Time to Apply
The product is particularly useful during the fruiting and produce-development stages. Where foliar application is used, spraying during the cooler parts of the day can help minimise rapid evaporation and improve crop coverage.
Application frequency should be decided according to crop requirement, soil and water analysis, plant nutrient status and local agronomic recommendations.
Application Tips
- Use clean water for preparing fertilizer solutions.
- Dissolve the product completely before application.
- Use the recommended concentration for foliar spraying.
- Avoid spraying during strong sunlight or extreme heat.
- Ensure even crop coverage during foliar application.
- Check irrigation system compatibility before fertigation.
- Use soil or leaf analysis where possible for accurate nutrient planning.
- Do not exceed recommended concentrations unnecessarily.
Compatibility
Solfert Ultimate can be incorporated into crop nutrition programs, but compatibility should be checked before combining concentrated fertilizer solutions with calcium-containing fertilizers, pesticides or other agricultural inputs.
Where an unfamiliar tank mixture is planned, conduct a small compatibility test first and follow the label directions of all products involved.
