- CAS No.
- Color & Physical Form
Potassium (K) is absorbed by the plants in larger amount than any other nutrient except Nitrogen. Although the total K content of soil is usually many times greater than the amount taken by the plants but in most cases only a very small fraction of the soil K is available to the plants for nutrition. The unavailable form of K accounts for 90-98% of the total soil K. The readily available form is only 0.1-2.0% Therefore It must be supplemented by applying K fertilizers in every crop to protect them from getting deficient and to avoid the economic yield loss.

Technically known as Sulphate of Potash, A complete water soluble speciality fertilizer that contains chlorine free high quality Potash and Sulphur, the most important secondary plant nutrient.
Importance of Potash and Sulphur in the plants:
- Structural component of cell membrane, mitochondria, chloroplast etc.
- Constituent of nucleic acid.
- Involved in photosynthesis, activation of several enzymes, energy transfer etc.
- Required for root and shoot growth.
- Gives aroma to the produce
- Sulphur is now recognized as fourth major plant nutrient after N, P and K.
- Helps in chlorophyll formation, necessary for photosynthesis.
- Essential constituent of many enzymes, proteins and essential fatty acids.
- Promotes nodule formation in leguminous crops.
- Promotes vegetative growth and root development.
- It helps in increasing the crop's resistance to insect and disease attack and environmental stress.
- Ensures timely maturity of the crop.
- Sulphur increases the yield and improves quality of the produce.
|Water Soluble Potash (as K2O) min. (in weight)||50.0%|
|Sulphur (as S) min. (in weight)||17.5%|
|Sodium (as NaCl on dry basis) max. (in weight)||2.0%|
|Total chlorides (as Cl on dry basis) max. (in weight)||2.5%|
Symptoms of Deficiency
- Small white spots develop on edges of leaves.
- Loss of chlorophyll causes death of the green tissues.
- Symptoms occur first on lower and older leaves generally.
- In cotton and wheat it appears on tip leaves.
- Weak and sic plants, lodging in small grains.
- Loss of resistance to diseases.
- Heavy loss of yield
- Deficiency symptoms of Sulphur are more likely closer to those of Nitrogen.
- Symptoms appear first on younger leaves and persist even after application of Nitrogen.
- Leaves become pale yellow or light green in colour.
- Plants are less grown, resembles stunted, short stalks and internodes.
- Less nodule formation in pulse (Legume) crops, reduction in N fixation from the atmosphere.
- Delayed maturity of the crops, fruits often does not mature and remain light green.
- Loss of yield in quantity with lower nutritional value.
Sampoorti Product Benefits
- Contains the highest Potash (K) content available.
- Increases crops yield and quality of produce .
- It is helpful in enzyme formation in plants.
- The presence of Sulphur is important for oilseeds and onion, garlic, tobacco and pea crops.
- This is virtually free from chloride, sodium & other harmful elements for plants.
- Field Crops: Cereals, Cash crops, Oil seeds, Pulses
Time and Method of Application with Dosage
- Suitable for Foliar application and drip irrigation.
- First Spray – Before grain / fruit setting.
- Second Spray - 10-15 days after first spray.
- 1-2 Kg. in 150-200 Lt. of water per acre.
- For Foliar Spray: 0.8-1.0 % solution in water (1-1.5 kg in 125-150 liter water is sufficient for spray in One Acre area).
- For Fertigation with irrigation water: 2- 3kg per Acre. For best results, 2-3 repeated sprays or fertigation are required at 12-15 days interval.
- Should not be mixed with Calcium fertilizers for Spray.
- Regular post application precautions like washing hands etc. should be performed.
- Keep in a cool and dry place.
- Keep out of reach of children.
