That depends on the city/county.
How much acreage will I need to plant to have a cost effective crop?
you at least need to live on acreage before you can be a registered farm
If the acreage is a square, you'll need 6,467 feet of fencing to enclose the area.
Two horses need about an acre to two acres each.
Need to know your location in order for an answer to be given.
Horses (all horses) need 1.5%-3% of their body weight in forage per day as a base for their diets.
Protein is essential for horses as it helps in muscle development, tissue repair, and overall growth. Horses need about 10-12 protein in their diet to maintain good health and performance.
Need more information. See discussion page.
How much grain a horse eats depends on how much work it is doing. Horses that do not do any work usually don't need any grain, just hay and grass. Some horses that are hard to keep weight on need grain, even if they don't do much work.
The acreage limit for 1 horse is approximately 5 acres, but if you have 10 acres and it is good grass you can put 3 horses on the peice of acreage. If it is'NT good grass though you should only put 2 on there. One horse needs one acre of fertile land. There should not be any harmful or posionous weeds/plants in the horse's pasture. If you have 2+ horses, you need the same amount of acres.
Likely you'll need around 10 acres.
Usually, horses need two pastures. They also need a place to shelter in warm days.
