Generally it is best to apply up to 150 lbs. For most regions this means 50 lbs. of N. in early spring, again in late May or early June, and finally again in September. Also, early December is an excellent time for a late fall application to stimulate tillering. It is one of the best treatments for an overgrazed pasture. Fertilizer applications will ensure ample grass production all season long, keeping your pastures healthy and prolific.
Every pasture needs a break to re-grow, recover, and be fertilized.
This can be accomplished easily by breaking a pasture into two or more sub-pastures, using either temporary or permanent fencing. In the spring there may be too much forage growing for the horses to keep up with. If so, the number of acres being grazed needs to be reduced, made into hay, or mowed off. In contrast, summer rotations will be longer, and supplemental hay feeding may be needed. The more a pasture can be divided, the easier it will be to manage.
