Farming Today This Week: Soil

Anna Hill meets Professor Jane Rickson at Cranfield University, where they are studying the properties of the Earth's living skin - soil.

Anna Hill travels to Cranfield University where scientists are studying the properties of soil - both on the farm and in the lab. This is the UN's International Year of Soils. Today we look at some of the threats, including erosion and degradation from intensive use, and what farmers can do to improve their soils. Anna visits the large-scale experiments set up to research the effects of things like climate change and farm machinery on soil. The producer is Sally Challoner.
