Not really. The information is already out there.
For the pasture you'll have to choose among various methods. Mowing, using chemical weed killers such as 2,4D, and running sheep or goats are the usual options. Cockleburr and burdock are annoying and hard to vanquish. We pull out cockleburr by hand, but I'm not sure it helps. If you put sheep in where there is cockleburr they'll collect the burrs in their fleece. Now the burrs aren't in the pasture, but you'll spend acres and kilowatts of time picking them out of the fleece.
Fencing. You'll need proper fencing for horses. Not barbed wire. Maybe electric. Again, all the info is out there if you'll just look.
