Many of us have heard of and practice nitrogen management in our programs. We vary type and qty as we go through the season. We also know that a lot of cool season and transition turf like the 4-1-2 or 3-1-2 NPK ratio. But what about the qty and timing of the K side of the fert operation? There has been talk here about how K is better absorbed when its ratio .6-.8 to 1 of N. However some are putting down a 5-10-31 in early to mid summer. How good is that going to really perform. Should out K amounts be managed independent of N rather than just as a percentage of N each time or a big chunk of the annual amount before stress time?
