0-0-62 Fertilizer
PotassiumAlso known as: Muriate of potash (also sold as 0-0-60)
0-0-62 is 0% nitrogen, 0% phosphate and 62% potash by weight. To apply 1 lb of potash per 1,000 sq ft, spread 1.61 lbs of product per 1,000 sq ft; a 50-lb bag covers about 31,000 sq ft at that rate.

How Much 0-0-62 to Apply
Lawn feeding is measured in pounds of nutrient per 1,000 sq ft. Here's how much product hits each common target.
| Target | Product / 1,000 sq ft | Per acre | 50-lb bag covers | Delivers (N-P-K lb) |
|---|---|---|---|---|
| 0.5 lb K₂O | 0.81 lb | 35.1 lb | 62,000 sq ft | 0-0-0.5 |
| 1 lb K₂O | 1.61 lb | 70.3 lb | 31,000 sq ft | 0-0-1 |
What It's For
Muriate of potash (potassium chloride) is the cheapest way to add potassium. Use it when a soil test shows low K, to improve stress, drought and cold tolerance.
When to Use It
Spring or fall, split into light applications. Often paired with fall nitrogen.
Before You Spread It
- Very high salt index: it burns easily. Keep it to about 1 lb K₂O per 1,000 sq ft per application or less, and water it in.
- Adds chloride. On salt-sensitive sites or sandy soils, sulfate of potash (0-0-50) is the gentler choice.
