The annual costs of soil degradation in England and Wales are between £0.9 and £1.4 billion, with a central estimate of £1.2 bn. These costs are mainly linked to loss of organic content of soils (47% of total cost), compaction (39%) and erosion (12%).

English farmers are losing valuable resource through diffuse pollution. 235,000 tonnes of nitrogen and 8,391 tonnes of phosphorus are lost every year that would otherwise help sustain farming.

UK soils store over 10 billion tonnes of carbon in the form of organic matter. Over half of the UK’s soil carbon store is contained in peat soils. Of Wales’ peat-lands, only 30% of the area is thought to be in good condition. Around 80% of Northern Ireland’s peat-lands have been degraded and need to be restored.
