This is a straight bag of the “K“ component of NPK fertilizers. Based on other Q&A, it is somewhere between 44 and 50+ on a traditional NPK formula. IF YOU NEED K, this is an economical, efficient, usable way to acquire it. If you don’t know if you need K, or how much, you’ll need to do a little research, and definitely will want to do a soil test (or test of whatever you plan to use it for) to see if you have a potassium deficiency. There are also lots of signs you can find on leaves that indicate potassium deficiency, but they can be confused with overwatering and other deficiencies (as noted in yet other Q&As) One thing I have not noticed in my quick scan of Q&As is the fact that a potassium deficiency can cause fruit set to be low, particularly in tomatoes. I didn’t really want to add nitrogen to my fruiting tomatoes via an “All-In-One” NPK special from the hardware store where the soil test showed sufficient nitrogen but the potassium in the planting bed was deficient, so this is exactly what *my* plants needed. Start with or soil test, or knowing the signs and symptoms of potassium deficiency, and be prepared to start slowly and experiment. Great stuff, good price, what’s not to like?

I divide it into five 1lb ziplocks. Apply 1lb per 1k sq ft, repeat monthly as needed. 1lb will dissolve almost completely in about 1.5gal of hot water. I do this in a bucket and stir with a kitchen scooper about 1 min to dissolve. Then pour into a 2 gal sprayer and top off with water. When pouring, the non dissolving stuff will stay at the very bottom. No straining required, no clogs in sprayer, nothing on filter. After spraying I go back and water in lightly to get off blades and onto soil. Amazing difference after a rain, my centipede is growing stolons and spreading like never before. A month later bare spots are filling in like magic. The sulphur added the best even greening I've ever had, no streaks. This is the way.

My grass color changes from light green to dark green. they grow strong and dense.

Good
