Muriate Of Potash (MOP)

Muriate of potash, also known as potassium chloride contains 60% potash. Potash is essential for plant growth and quality. It plays a vital role in the production of proteins and sugars. It also protects against draught by maintaining plants water content which in turn is a benefit for photosynthesis as leafs maintain their shape / vigor. Potassium chloride (commonly referred to as Muriate of Potash or MOP) is the most common potassium source used in agriculture, accounting for about 95% of all potash fertilizers used worldwide. Its nutrient composition is approximately: Potassium: 50%, Chloride: 46%. Muriate of Potash may be grey/white/pink or red, depending on origin.

Potash varies in color from pink or red to white depending on the mining and recovery process used. White potash, sometimes referred to as soluble potash, is usually higher in analysis and is used primarily for making liquid starter fertilizers. KCl is used in medicine, scientific applications, and food processing. It occurs naturally as the mineral sylvite and in combination with sodium chloride as sylvinite. Fertilizers containing potassium must be applied wherever soil potassium reserves are inadequate for targeted crop or pasture production. Potassium can be applied as a straight fertilizer, or as part of a blended or compound fertilizer with nitrogen and phosphorous.

Potassium, the third essential nutrient plants demand, assists in photosynthesis, fruit quality, the building of protein, and the reduction of disease. When selecting a fertilizer – whether it’s for annuals, vegetable gardens, trees and shrubs, perennials or lawns – the first question to answer is, “What analysis do I need?” The analysis is actually the three large numbers you see on every fertilizer label – put there by law – such as 10-20-10 or 10-10-10 or 18-46-0. These numbers represent the percentage (by weight) of the three major nutrients required for healthy plant growth, always in the same order, Nitrogen-Phosphorous-Potassium (N-P-K). Each of these nutrients affects the plant growth differently and the formulation you select should depend on your specific gardening needs.

MOP has a high nutrient concentration and is therefore relatively price competitive with other forms of potassium. The chloride content of MOP can also be beneficial where soil chloride is low. Recent research has shown that chloride improves yield by increasing disease resistance in crops. In circumstances where soil or irrigation water chloride levels are very high, the addition of extra chloride with MOP can cause toxicity. However, this is unlikely to be a problem, except in very dry environments, since chloride is readily removed from the soil by leaching.

BENEFITS OF MURIATE OF POTASH (MOP):

* Has higher potassium content than other fertilizers and dissolves readily.

* Is the only form of potassium used for pasture.

* Mixes well with all other fertilizers and is rarely used on its own.

* Is a cost effective straight quick release potassium source, which can be used for both capital and maintenance applications.

* Replaces lost potassium when hay or silage is removed from the farming system.

* Muriate of Potash is a cost effective straight quick release potassium source, which can be used for both capital and maintenance applications
