Potassium Sul-Po-Mag Sulfur

This is a blend of sulfate of potash (potassium sulfate), sul-po-mag, and elemental sulfur. This is intended to be used when you have a deficiency in potassium, especially when magnesium is low (although due to the fact that high magnesium can lower the availability of both potassium and magnesium, this product is still useful to feed crops on high-mag soils). 215 lbs per acre provides 76 lbs of potash. This application level (215 lbs peracre) also provides 1/4 the yearly max (1/3 the normal max) of elemental sulfur. This blend is designed to be used along with either the copper boron sulfur, manganese boron sulfur, or zinc boron sulfur blends to provide your max yearly sulfur application.
The yearly recommended application limit for this blend is 215 lbs per acre/year
The yearly application limit for this blend is 645 lbs per acre/year
Always check with your organic certifier before using any product.
