ProScape® 16-4-8 is a premium fertilizer for any highly maintained turfgrass area where it is desireable to have potash that lasts as long as the controlled-release nitorgen.  Now you can apply potash lasting as long as the slow-release nitrogen while providing a much more efficient delivery of this extremely beneficial nutrient.  The iron (Fe) is in the sucrate form which is sufficiently insoluble to eliminate the danger of staining concrete surfaces yet provides a high degree of plant resonse according to university research.
