When nitrogen based fertilizers are being applied, horses should be removed from the pasture. Horses should not be returned to the pasture until after it rains. It takes about a half inch of rainfall to dissolve granular nitrogen. Ideally, it is best to keep the horses off of the pasture for at least 2 - 3 weeks after fertilizing the grasses. This will allow time for the grasses/forages to regrow.
