Horses are poor utilizers of pasture, compared to cattle or sheep. Most horse pastures contain a large proportion of weeds and "roughs" where horses are the only grazers. Horses will not eat pasture that is contaminated with horse dung. This usually causes the contaminated area to become larger and the grazing area smaller. The pasture growing round the dung patches is usually lush and looks to be the best feed, while the patches in between will look overgrazed.

Where possible, horses should be grazed in conjunction with cattle or sheep. In addition to helping calm the horses; the other species will clean up the "roughs" while also reducing the worm contamination on pasture. Although harrowing can also be useful to spread the dung around, in moist conditions and when the grass is long it may spread worm eggs, making a larger area of the paddock infected. Where no cattle or other grazers are available, it is essential to remove the manure or spread it around regularly during dry periods, when the sun and ultraviolet rays will tend to destroy eggs and larvae.

Your horses will leave some big manure piles around the pasture and especially in the corners. Spread the horse manure out on the pasture with a drag harrow and rake out the pasture corners to break it up in smaller pieces; it helps to keep the fly larvae in the manure from hatching out and bothering your horses.

You will need a manure spreader to spread the manure you shovel out of your loafing sheds and stalls. Your horses will eat a lot of the grass in your pasture -- but you will still have to mow the pastures periodically and you will need to use a weed-eater under and along all the fences. You will need to keep a check out for any plants of the nightshade family as they are poisonous to your steeds.

Grazing animals deplete soil nutrients progressively, which in turn leads to poor pasture quality and growth rate. This should be regularly monitored by soil and pasture analysis. Pasture should be top dressed with fertilizers to replace identified nutrient deficiencies. Check with your State Agricultural Agent (each state has an Agricultural College and Agents attached) to learn to identify soil nutrient needs and to show you how to destroy noxious plants properly. Make certain that there is always plenty of clean fresh water in the pasture and that the water trough is kept dutifully clean!
