About Potash:
Potash is the general name given to various inorganic compounds that contain potassium in a water-soluble form.
Ores: The principal ore is sylvinite, a mixture of sylvite (KCl) and halite (NaCl).
Uses:
Over 90% of potash is used as fertilizer and it is one of the three primary agricultural nutrients (Nitrogen, Phosphorus and Potassium or N-P-K).
Potash can be used on all plants to boost plant health and nutrition as well as to increase crop yields.
While all potash fertilizers contain potassium there are a number of different forms in which it exists.
Among these forms is Sulphate of Potash (SOP), a premium potash fertilizer that is free of chloride (a compound considered harmful to plants) is used primarily on high-value crops, usually leafy plants, fruits and vegetables
On the other hand, Muriate of Potash or MOP contains some chloride, is commonly used on carbohydrate-type crops, such as wheat.
Potash reserves in India: Rajasthan (alone contributes 89% to the total resources), Punjab, Madhya Pradesh and Uttar Pradesh.
Potash reserves across world: It mainly located in Canada (31%), Belarus (21%), Russia (11%), China (10%), USA (6%), Germany (4%) and Chile (3%).
