Pasture cropping works anywhere
“Drill a cereal into your pasture and you can harvest grain and graze the same field every year, with no yield loss and soil carbon doubling.”
The method comes from one Australian farm and needs a grass that sleeps through winter and a spring that reliably rains. Controlled Australian trials lost 35 to 65% of the grain; the only European trial, in Madrid, lost 50 to 61% in the dry year and its authors judged the system not adapted to central Spain.
Where it comes from
Colin Seis's farm "Winona" in New South Wales, where a winter cereal is direct-drilled into native summer-active grasses as they go dormant, and the case studies, courses and talks built on it. The soil-carbon doubling and "20% more profitable" figures are the farm's own, relayed by the advocacy group Soils for Life (case study).
Who benefits
Course providers and consultants teaching the method, and the wider regenerative movement for which it is a flagship. None of that makes the farm's own results false; it makes them one farm's results.
What the evidence says
The controlled trials lost grain. Wheat pasture-cropped into established perennial grass in central-western New South Wales yielded 35% and 49% less than conventional in two seasons, and across trials pasture-cropped wheat was "consistently lower" than no-till, by as much as half, limited by nitrogen and moisture (NSW Department of Primary Industries and Grain & Graze, as reported; NSW Local Land Services). The official advice is that the system pays only when livestock eat the extra forage.
The one European trial failed the dry year. At La Poveda near Madrid, on 385 mm of rain from 2015 to 2019, barley drilled into dormant Cynodon and Eragrostis swards matched conventional yields in the wet years and fell 50 and 61% in the dry 2019. Two of the four summer grasses tried did not survive the winter. Weeds did fall 80 to 90%. The authors' conclusion: pasture cropping "appears not to be well adapted to the environmental conditions of central Spain" (Plants, 2020, open access).
The mechanism explains both. The system works where the perennial is truly dormant while the cereal fills grain and where spring rain is reliable, the Australian tablelands. Where the grass is not asleep, or the rain fails, two crops share one spring's water and the cereal loses.
Europe already has a version with 85 years of data. Rothamsted's Woburn experiment shows three-year leys in an arable rotation lifting topsoil carbon from 0.98% to about 1.24 to 1.40% over 70 years, against 0.80 to 0.91% under continuous arable, with more wheat and less nitrogen after the ley (European Journal of Soil Science, 2017).
What to say instead
"In Europe, put the grass in the rotation as a ley, and graze the cover crop. Drilling grain into a live pasture is untested here and failed its one dry-year test." And before any of it, check whether the field is permanent grassland under the CAP; if it is, sowing a crop is a land-use conversion. The ley–arable page grades all four forms.
