Muriate of Potash (0-0-60) vs Sulfate of Potash (0-0-50): Compared
Muriate of potash is cheaper and works well for most crops and lawns. Sulfate of potash is essential for chloride-sensitive crops like berries, tobacco, potatoes, and fruit trees, and adds beneficial sulfur to the soil.
How Do Muriate of Potash (0-0-60) and Sulfate of Potash (0-0-50) Compare?
Sulfate of Potash (0-0-50) wins 3 of 5 categories. The breakdown below covers cost, chloride-sensitive crops, sulfur content, general lawn use, soil salinity.
| Factor | Muriate of Potash (0-0-60) | Sulfate of Potash (0-0-50) |
|---|---|---|
Cost Muriate of potash costs roughly half as much as sulfate of potash per pound of potassium | ||
Chloride-Sensitive Crops Muriate contains 47% chloride which damages berries, tobacco, and some fruit trees. Sulfate is chloride-free | ||
Sulfur Content Sulfate of potash provides 18% sulfur, an important secondary nutrient for crop quality | ||
General Lawn Use Turfgrass is chloride-tolerant, and the lower cost makes muriate the standard for lawn potassium | ||
Soil Salinity Sulfate of potash has a much lower salt index, making it safer for saline soils and greenhouse use |
When Should You Choose Muriate of Potash (0-0-60)?
Choose Muriate of Potash (0-0-60) when you prioritize cost, general lawn use. Muriate of potash costs roughly half as much as sulfate of potash per pound of potassium
