What is SOP fertilizer?

Also known as sulfate of potash, or SOP, potassium sulfate is a premium potash fertilizer with a number of benefits over the more commonly used muriate of potash (MOP).

What is kts fertilizer?

What is in potassium sulphide?

Potassium sulfide, is an inorganic salt found as a mixture with potassium hydrosulfide and used as this mixture to manufacture pyrotechnics. Formula and structure: The potassium sulfide chemical formula is K2S. The molar mass is 110.26 g/mol. The molecule is formed by two potassium cation K+ and one sulfide anions S2-.

Which is best potash fertilizer?

Potassium Chloride — also known as Muriate of Potash, is the most widely used potassium fertilizer. It can cause plants to burn if directly applied but is safer in powdered and soluble mixtures as they are weaker mixes.

Which is better MOP or SOP?

It works better on crops that are sensitive to chloride, which can be toxic to some fruit and vegetable plants. SOP is not a naturally occurring mineral, and usually must be produced through chemical methods. Because of the resource-intensive processes used to create it, SOP is priced higher than MOP.

What is the weight of KTS fertilizer?

Each gallon of KTS contains 3 pounds of potash (K20) and 2.1 pounds of sulfur (S). KTS can be applied by drip, sprinkler or flood irrigation. It may be blended with other fertilizers or applied as a foliar treatment on selected crops.

How much potassium does your crop require per acre?

“A standard benchmark is that potassium uptake for a 180-bushel corn yield is 240 pounds of potassium per acre. The critical level of potassium in the soil for optimum performance is approximately 165 ppm.
