We have been on a one acre dry lot in the Mojave Desert for ten years with 6 horses. Our place is too small and we have too many horses to reduce inputs with grazing or browsing, we feed Tmothy hay and supplements mixed with pellets. We have reduced output by composting the poop and using it in the garden and mix into the sand in the dry lot to help retain moisture. You can see what I've got going on at www.equuscape.org Our horses live in an 'open equine environment' with wind break and shelter but no stalls or barn. In this arrangement the sapce is organized into lanes that lead to water, feed, minerals places to roll and play. The horses are motivated to move around and exercise as a herd and I find that is of huge benefit to their wellbeing.
