Potassium is known to interact with almost all the other essential plant food nutrients. It is important for enzyme activation, efficient use of water, photosynthesis, transport of sugars, water and nutrient movement, protein synthesis, starch formation and crop quality.
Deficiencies result in low yields, mottled, spotted or curled leaves, scorched or burned look to leaves.
Functions in plant:
Potassium is necessary for formation of sugars, starches, carbohydrates, protein synthesis and cell division in roots and other parts of the plant. It helps to adjust water balance, improves stem rigidity and cold hardiness, enhances flavour and colour on fruit and vegetable crops, increases the oil content of fruits and is important for leafy crops.
