Our Changing World - Water repellent soil

From Afternoons with Jesse Mulligan, 3:32 pm on 23 December 2010

For anyone who wants to grow plants, getting the right amount of water into the soil is extremely important.

Ruth Beran meets his supervisor Markus Deurer who explains that rather than soaking up water, most of the soils sampled could actually repel water.
