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.
Need more information. See discussion page.
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.
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.
Likely you'll need around 10 acres.
Usually, horses need two pastures. They also need a place to shelter in warm days.
Not necessarily. Stabled horses usually will need to be rugged if they are used to a sheltered environment. Paddock horses are much like wild horses in the sense that they stay together for survival. They will group to keep warm if they have too.
