Improve P, K and S Uptake and Efficiency

Reaction MKS is a liquid plant food designed to provide supplemental nutrition and correction of Mg, K, and S deficiencies. It contains complexed potassium, magnesium and sulfur using Steric Chemistry to protect these molecules from being tied up in the soil, resulting in highly efficient nutrient availability.

Reaction MKS is derived from potassium magnesium sulfate (AKA sul-po-mag)

Brandt Reaction MKS 0-0-4 helps maintain sports turfgrass  (golf course greens, tees, fairways and roughs; sports turf) vigor when P, K and S are in high demand; and boosts plant growth during critical growth and stress periods. It is especially beneficial on highly maintained sports turfgrass areas and/or in high alkaline/acid soils or where other soil chemical problems exist.

This product is most effective when applied through an irrigation system or banded. This product may be applied separately or in conjunction with most other fertilizers. It is compatible with most acid based fertilizers and other plant nutrients. However, a compatibility test is recommended if the desired combination has not been previously used.
