Manure Applications

It will be difficult to impossible to produce low K grass forage on stands receiving significant manure applications. Many dairy farms are in a state of potassium surplus due to years of spreading manure, and use perennial grass both as a manure sink and as dry cow forage. This results in potentially severe problems in properly managing potassium content of dry cow rations. If some K fertilizer is required due to low soil K, this could come from a manure application after spring harvest.
