How long should my horse stay off a fertilized or sprayed pasture?
Sussex County Delaware
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. For additional information regarding pasture management and fertilizer and/or herbicide application, please visit eXtension Horses (http://www.extension.org/horses). You may also wish to visit the Forages section of the UD Cooperative Extension Equine Blog (http://extension.udel.edu/equine). You will find information on forages under the Fact Sheets tab.
