it depends on how many horses you have

how much onion seed is needed to plant a 1/4 mile row
Yes. If you are hand-broadcasting seed over a pasture or in spots where a cow can eat it, she will defecate it out. This seed will grow from this manure and thus repopulate the current stand in the pasture.
That depends entirely on the condition of the grasses in your paddock, the climate, the maintenance you put into the paddock, and whether you intend for the horses to live in the paddock full time. A typical stocking rate (the number of animals on a given area) is 1 adult horse per acre of pasture. In order for an acre of pasture to actually support a horse 24/7 however, you must remove manure from the pasture daily, mow the pasture regularly, fertilize and broadcast seed the pasture, etc. all of which requires the horse to be OFF the pasture for various periods of time. I live in central IL where this time of year everything is wet and muddy. A horse on 1 acre of pasture here, right now, will destroy the pasture in about a week just by walking around tearing up the grasses. If you are only worried about how many horses you can put together, that will depend on how well they get along. If they don't get along well, they need enough room so that they don't irritate each other and the paddock fences must be safe enough that if they get to bickering and running each other around, they don't break through the fence or get hurt on it.
That depends on where you live and your soil type. You will need to visit your local seed grower for information on seeding rates for your area.
Your horse has been doing the fertilizing all along. You can spread the manure with a drag hooked to a small tractor or riding lawnmower. If you do decide to use a manufactured fertilzer make sure you have some other pasture for at least six months. Read the label to make sure it's safe for animals and humans. A good alternative is to throw grass seed on your pasture at the begining of the wet season in your area. There are some good commercial products for grasses that horses love.
A buckeye is the seed of a horse chestnut.
In an ideal situation, you would have at least 2 acres where you could keep your horse outside 24/7 where he can eat and sleep as he pleased. However, many horses manage in one acre or less when they are suplemented in plain grass hay. This should be left where a horse has access to it 24/7, preferably spread out around his pasture.
The pasture needs to be tilled before you can plant any corn. Pasture grasses can be so competitive that they don't allow the corn to germinate into a plant, so you need to eliminate the competition by tilling the pasture. THEN you can seed the corn. However, if you have access to a strip-till implement, especially one with a band sprayer attachment, you can interplant the corn with the pasture. It's still important to kill the pasture in the narrow strips where the corn is planted. Fertility and plant population must also be adjusted accordingly.
Yes. A horse chestnut is referred to as a "Conker"
It can be feed to horses and it is good for them.
He was an agriculture pioneer and he perfected a horse drawn seed drill and later a horse drawn hoe.
