When is World Soil Day, and what is the 2026 theme?
World Soil Day is 5 December every year, including 2026. The UN General Assembly endorsed the date. FAO’s 2026 theme is “Tackle soil compaction, boost food production.” Compaction is what happens when soil is pressed, by machinery, by trampling, by rain on bare ground, until roots, water and air cannot move through it.
FAO’s World Soil Day page is the source for the date. The theme is the one FAO’s 2026 events list under that day. A local event can use different wording. The global theme this year is compaction.
What can a farm listing honestly say on World Soil Day?
The farm’s name, where it is, what it grows, and any practice, water source or soil note the directory already holds. The World Soil Day collection is for farm shops, markets, veg boxes and food growers. It does not add a compaction score that was never measured.
National Tree Week, 21 to 29 November, is the UK week for trees near you. Soil and trees meet in the same ground. They are filed as two dates because the calendars are different.
