Potassium plays an important role in the health of turfgrass through helping to alleviate stress, aid in stomatal regulation, and maintain turgor potential. Potassium’s role as a regulator nutrient in turfgrass helps it to weather salinity, stressful temperature variations, drought, and withstand wear tolerance on golf course greens and tee boxes.
Intrepid Trio is an ideal K source for turfgrass as well in that due to its low slat content it isn’t as apt to burn the grass. Potassium deficiencies on turfgrass will typically occur on sandy, low CEC soils with a pH of <5.5. Continued use of heavy N fertilizers without a K source can also create a K deficiency. When determining K needs in turf applications, tissue analysis may be more accurate than soil analysis.
