Muriate of Potash 00:00:60

Potassium fertilizers are commonly used to overcome plant deficiencies. Where soils cannot supply the amount of K required by crops, it is necessary to supplement this essential plant nutrient. Potash is a general term used to describe a variety of K-containing fertilizers used in agriculture. Potassium chloride (KCl), the most commonly used source, is also frequently referred to as muriate of potash or MOP fertilizer (muriate is the old name for any chloride-containing salt). Potassium is always present in minerals as a single-charged cation (K+).

Potassium chloride is the most widely used K fertilizer due to its relatively low cost and because it includes more K than most other sources...50 to 52% K (60 to 63% K2O) and 45 to 47% Cl-. Over 90% of global potash production is used for plant nutrition. Potassium chloride is often spread onto the soil surface prior to tillage and planting. It may also be applied in a concentrated band near the seed. Since dissolving fertilizer will increase the soluble salt concentration, banded KCl is placed to the side of the seed to avoid damaging the germinating plant.

Potassium chloride rapidly dissolves in soil water. The K+ will be retained on the negatively charged cation exchange sites of clay and organic matter. The Cl- portion will readily move with the water. An especially pure grade of KCl can be dissolved for fluid fertilizers or applied through irrigation systems
