University of Kentucky research has shown that soil potassium plays a key role in reducing broomsedge in forage stands and increasing yields from cool season forages. A spring article sent to 77 farmers highlighted that many farmers underfertilize with potassium. Low potassium will prevent nitrogen fertilizer from having its full yield enhancing effect. The results of Extension research on the use of fertilizers for broomsedge control was shared with producers in a newsletter. The agent also discussed the findings with a local farmer and subsequently with the farmers crop advisor. The field was soil tested and recommendations were followed for a 60 acre hay field.
