Nutrient Source Specifics – Potassium Chloride

 |  Fact Sheet  |  Research

NSS-3 Potassium Chloride – 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 (muriate is the old name for any chloride-containing salt). Potassium is always present in minerals as a single-charged cation (K+).
