Planning a Simple Pasture Rotation System

Why Rotation Pays on a Small Acreage

If you keep horses on a smallholding, you already know the crunch: too many hooves on too few acres. A horse grazing the same patch day after day will eat it down to the soil, leaving a mat of droppings and bare, poached ground behind. Worm larvae climb the stems of short grass, so the more tightly the field is grazed, the more infective those mouthfuls become.

Splitting your grazing into smaller paddocks and moving the horses on a regular cycle changes all of that. Grass gets time to recover and regrow, dung is left behind to break down in the sun rather than being grazed over, and the worm burden on the pasture drops because larvae need moisture and a living host to survive. It is one of the cheapest improvements you can make, and once the routine is set it takes minutes a day.

Working Out How Many Paddocks You Need

The honest answer is: as many as you can reasonably create, but four is the sensible minimum and six is comfortable. The old rule of thumb for the growing season is to rest each paddock for at least three weeks, ideally four. With four paddocks you can graze one while three rest, giving a twenty-one day recovery if you move weekly. With six, you can move every five or six days and each paddock rests for nearly a month.

As a rough guide for a native pony or a good-doer on decent pasture, allow about half an acre of actively growing grazing per horse across the whole rotation, plus a separate area for winter turnout and a small holding paddock near the gate. Two horses on three acres of reasonable Cheshire or Devon grass will manage perfectly well on a five-paddock system.

• Four paddocks – workable for two horses on well-draining land.
• Six paddocks – the sweet spot, forgiving when growth slows.
• Plus one sacrifice area – a hard-standing or well-drained strip for the wet months.

Setting Up the Fencing and Water

You do not need permanent post-and-rail for every division. Electric tape on lightweight posts is ideal because you can shift a line in ten minutes if the layout is not working. Use two strands at roughly 60cm and 100cm for horses, and a decent mains-powered energiser if you can reach the field; otherwise a 12-volt battery unit with a good earth rod driven into damp soil. Check the earth stake whenever the fence feels weak.

Water is the part people forget. Moving a trough is far more work than moving a fence, so plan your paddocks around a central water point where possible, or use a gateway layout that lets the horses reach a trough from two paddocks at once with a gap in the tape. Keep gateways sited on the driest ground you have.

The Moving Routine

Move the horses when the grass in the current paddock is grazed down to about 4cm – roughly the height of a golf ball lying on the sward. Do not let them take it shorter. When you move them, leave the droppings where they fall in the paddock you have just left; the sun and dung beetles will deal with them, and any worm eggs are left behind rather than picked up on the next pass.

Keeping a simple notebook or a chalkboard by the tack room door works better than memory. Note the date each paddock was vacated. If you are ever unsure whether a paddock has rested long enough, err on the side of extra days. In cold or dry weather, larvae die off faster, so resting can be shortened; in a mild, damp autumn, extend it.

Keeping Grass Growing Through the Year

Growth in the UK is not linear. You will get a flush in April and May that you cannot keep up with, a slump in July if it dries, another flush in September, and near-nothing from November to February. Plan for that.

• Spring flush: strip-graze with a back fence so the horses cannot return to what they have just eaten, and consider a muzzle for laminitis-prone natives.
• Summer slump: slow the rotation, rest paddocks longer, and top any rank, stemmy patches before they seed.
• Autumn: this is your repair window – harrow, overseed bare patches, and let the last paddock grow long enough to stand over winter.
• Winter: bring them onto the sacrifice area or a well-drained paddock and accept that it will look rough by March.

Small Jobs That Make the System Work

Harrow in dry weather to spread droppings and break up worm eggs, but never harrow and then graze the same paddock immediately – leave it at least three or four weeks. Poo-pick the paddock that is about to be grazed if the ground is too wet to harrow, and always pick up around gateways and water troughs, which are the highest-risk spots for worm larvae.

Finally, a word on worming. Rotating grazing is not a substitute for a proper programme, but it does mean you can move towards faecal egg counts rather than blanket dosing every twelve weeks. Fewer chemicals, healthier dung fauna, and better grass in the long run – which is exactly what a smallholding should be about.
