My mother has 25 acres in North-Eastern NSW on which she runs around 10 horses. She has been grazing the horses in a continuous fashion and after many years the pastures are in a truly sorry state....totally overgrazed, bare earth in places, extensive compaction, some topsoil loss due to lack of ground cover, huge weed infestations. I've finally convinced her of the virtues of rotational grazing and she is now very eager to make it happen, so I was hoping for a little advice from anyone who has rotationally grazed horses before. I've read that for horses you should graze until the pasture is no less than 5cm (2in) in length and spell until it reaches at least 15cm (6in). What I'm struggling with is: 1. Any idea what sized cells you would approximately need for a group of around 10 horses, and how long you would graze them in each cell? The total grazable area is 25 acres. 2. Suggestions on good ways to manage the fencing. E.g. should she create small cells using electric tape and step-in poles, and move these around within the boundary fences? 3. Is there anything else that you would suggest to help mend her land?
