Rotational and planned grazing
Splitting pasture into paddocks and resting each one. Well evidenced for output on improved temperate grass, unproven on dry rangeland at the same stocking rate, and the branded versions have not been shown to beat ordinary rotation. The drought tool is the plan and the forage bank, not the paddock count.
The short answer
Splitting fields and resting them raises utilisation and output on improved pasture. Ireland's Teagasc puts the gain at up to 0.25 kg of liveweight a day, about 50 kg an animal over a season, and values an extra spring day at grass at €51 for a 40-cow herd (2026). Rothamsted's interim trial found more soil organic matter, fewer weeds and more liveweight per hectare than set stocking, which we have at second hand because the report itself could not be read.
Holistic and mob grazing have not been shown to beat ordinary rotation. A 2017 meta-analysis found no difference in plant cover, biomass or animal gain; a 2016 review found half the studies the method's promoters cite are surveys, and put grazing's carbon storage near 0.35 t per hectare a year, seven times below the famous claim.
The drought tool is the plan, not the paddocks. A rotation banks forage and a written plan forces the destocking decision early. On dry rangeland at the same stocking rate, rotation alone grew no more grass in 87% of experiments.
Two questions, two answers
Almost every argument about grazing systems runs two questions together. Does rotating stock beat leaving them in one field? On improved temperate pasture, yes, and the evidence is European and good. On extensive dry rangeland at the same stocking rate, no. Does holistic, adaptive or mob grazing beat ordinary rotation? Not shown, anywhere, in a controlled comparison. This page keeps the two apart, because a farmer in Ireland and a farmer in Extremadura need opposite halves of the answer.
The confound that runs through everything
A farm that converts to rotation usually changes more than its fences. It often changes stock numbers: the Portuguese sheep farm below ran about 10% fewer ewes per hectare after converting. It compares itself with its own past, across different weather years. And it starts measuring and planning, which may matter more than the paddock count. Every result on this page carries that caveat, and the first thing to do on your own farm is to keep a set-stocked field at the same stocking rate so you can tell the method from the numbers.
What it is
- Set stocking or continuous grazing: animals in one field all season. The control.
- Rotational (paddock) grazing: paddocks grazed in turn with rest periods. Teagasc's beef template is 7 to 8 paddocks, 3 days grazing, 21 days recovery in mid-season.
- Holistic planned or adaptive multi-paddock grazing: many paddocks, high density, short occupation, long and variable rests planned against forage growth on a chart; sold with claims of restored grassland and large soil-carbon gains.
- Mob or tall-grass grazing: very high density into tall forage, a third or more trampled as litter, rests of 60 days or more.
How it is meant to help against drought
Rest lets grass rebuild leaf and root before it is grazed again. Taller residual and trampled litter shade the soil, cut evaporation and raise infiltration. A rotation leaves a bank of ungrazed forage when growth stops, and a written plan makes the destocking decision before the stock make it for you. All of that is real and uncontroversial. What is contested is whether anything beyond ordinary rotation adds to it.
What the evidence shows
Rotation against set stocking: it depends on the system
On extensive rangeland, the most-cited synthesis reviewed the experiments and found plant production equal or greater under continuous grazing in 20 of 23 (87%), with no rotation advantage for animal performance or production in 92% and 84% of studies; at a given stocking rate, moving stock around the map changes little (Briske et al. 2008, Rangeland Ecology & Management). Those are semi-arid, mostly North American, experiments.
On improved temperate pasture the answer is different and European. High-quality rotationally grazed grass adds up to 0.25 kg of liveweight a day, about 50 kg an animal over 200 days, worth about €250 an animal at recent prices, and an extra day at grass in spring saves €51 a day in feed for a 40-cow suckler herd (Ireland, 2026, Teagasc). Scotland's SRUC says farmers moving from set stocking to rotation "have doubled their output, from an increased stocking rate and/or improved animal performance" (2025, SRUC). Rothamsted North Wyke's cell-grazing trial against set stocking found rotationally grazed plots with a faster rate of soil organic matter accumulation, a lower weed burden, more available phosphorus and potassium, and higher liveweight gain per hectare (UK, interim report 2023, as reported by the Farm Carbon Toolkit; the report itself could not be machine-read for this page).
Reading. Rotation raises utilisation, so on grass that grows fast it lets you carry more or finish faster. On rangeland that grows slowly, there is little extra to utilise. This is the grazing form of this site's rainfall line: the benefit exists where forage grows fast enough to bank.
The branded methods against ordinary rotation: not shown
- A 2017 meta-analysis of Holistic Planned Grazing against season-long continuous grazing found no difference in plant basal cover, plant biomass or animal gain (Hawkins, African Journal of Range & Forage Science). Advocates dispute which studies should count.
- A 2016 independent review examined the 11 studies the Savory Institute cites: five are surveys or interviews and six quantitative; "no review study has established that holistic grazing is superior to conventional or continuous grazing"; improved grazing stores on average about 0.35 t of carbon per hectare a year, roughly seven times less than the 2.5 t the method's climate claims imply. Its conclusion: holistic grazing "could be an example of good grazing management, but nothing suggests that it is better than other well-managed grazing methods" (Nordborg 2016, summarised by TABLE).
- Paired ranches in the humid south-eastern United States managed adaptively showed more soil carbon, more litter and cover, less bare ground and infiltration about three times higher than continuously grazed neighbours; the authors note adaptive grazing "can allow an increase in livestock carrying capacity", so stocking may differ (PeerJ 2022, as reported). The one arid adaptive grazing trial found no improvement in forage quantity or quality (Augustine et al. 2020, as reported).
- Northern Great Plains ranches, 2026: adaptively grazed ranches had 45% less soil nitrogen and 11% less soil organic carbon than conventional neighbours (Apfelbaum et al., as reported; paywalled). A negative result on the axis the method is sold on.
The desertification and climate claims have their own claims page; "mob grazing grows more grass" has another.
European measurements, including the dry south
Portugal, paired pastures under aridity stress. Rotation since 2018, sampled 2022: 71 ha in 16 areas against 37 ha of continuous grazing in 10. Soil organic carbon 27 to 67% higher, total nitrogen 67 to 77% higher, water-holding capacity 6 to 17% higher under rotation; no difference in bulk density or microbial biomass (Journal of Environmental Management, 2025, abstract via Europe PMC). Four years, paired, real; stocking rates are not in the abstract.
Alentejo, Portugal, montado sheep farm. About 200 ha converted to rotation in 2018: measured soil carbon accrual of 2.47 to 2.92 t per hectare a year, farm emissions down 34%, lamb footprint 16.2 to 12.7 kg CO₂e per kg liveweight (Frontiers in Environmental Science, 2026). Two caveats the paper itself makes possible: it is before and after, and the flock fell from 2,200 to 2,000 ewes on the same land, about 10% fewer per hectare. The carbon figure is also about seven times the independent review's average. Both cases are on the case studies page.
United Kingdom. Defra commissioned a nine-farm comparison of mob and conventional grazing in 2021, measuring livestock performance, soil, biodiversity and nitrogen losses; no results are published yet (FarmPEP). A six-farm dairy field lab is under way. One estate in Fife reports £380 saved per livestock unit a year under mob grazing, almost all of it straw, machinery, fertiliser and minerals no longer bought, while cattle took four months longer to finish at 30 kg lighter carcasses (Scotland, 2020, Farmers Weekly; a single farm converting to organic at the same time). That is the honest shape of many mob-grazing accounts: the saving is inputs, the cost is slower, lighter stock.
Drought specifically
No European trial isolating the drought-year effect of grazing system at fixed stocking was found. What is supported: a rotation banks forage and a plan forces earlier destocking, which anyone can copy; higher infiltration and water-holding capacity under rotation are measured in Portugal and in the humid United States; on arid rangeland the one adaptive trial found no forage gain. The drought benefit is real where there is enough rain to grow a bank, and unproven where there is not.

Timeline: utilisation and animal-performance gains in the first season; soil organic matter and infiltration changes measurable at about four years; carbon claims need a decade and a control.
Commitment
Reversible. Fencing and water are sunk but salvageable; stock numbers and rotation length change any season. Nothing is permanent except the trough plumbing.
How to start
- Fence and water first. Split one block into 6 to 8 paddocks with temporary electric fence and a trough in each; 3 days on and 21 days rest is the temperate template, and the rest lengthens as growth slows.
- Keep a set-stocked comparison field at the same stocking rate. Without it you will never know whether the method or the stock numbers did the work. The measure-something page collects this advice from across the site.
- Measure residual height and recovery days, and write the plan down. The chart is the point of "planned" grazing.
- Decide the drought rule in advance: the cover or rest length at which you destock or supplement. The plan, not the paddocks, is the drought tool.
- Try mob grazing on one block once rotation works, and expect slower finishing.
- Claim what pays: Spain's extensive-grazing eco-scheme, Poland's extensive grassland practice, the UK's grassland actions.
Risks and failure modes
Overgrazing when moves slip. High density with no rest is worse than set stocking, and it is the commonest failure.
Animal performance on mature forage in mob systems: four months and 30 kg on the Fife estate.
Labour and water logistics, and burn-out on daily moves.
The stocking-rate confound, in both directions: gains that are really destocking, and losses when density is raised on the strength of the method's claims.
Carbon over-claim. 0.35 against 2.5 t per hectare a year, and a 2026 study finding adaptive ranches with less soil carbon.
Arid rangeland. No forage gain in the one adaptive trial; 87% of rotation experiments without a plant-production gain.
Advocacy sources. The method's promoters sell the courses and half their cited evidence is surveys. The sceptics are named on this page too; read both.
Claims checked. Holistic grazing reverses desertification and climate change and Mob grazing grows more grass. Two Portuguese grazing studies are on the case studies page, with their caveats. For grazed trees, see agroforestry; for the permits a new trough or track may need, the permits page.
Grass in the rotation. Where the ley meets the plough is the ley–arable page: 85 years of Woburn soil data, the one European pasture-cropping trial, and the CAP permanent-grassland rule that decides whether a field can be cropped at all.
