'I thought I knew quite a bit about earthworms – until I picked up this charming little book' Nick Baker 'Many wonderful wormy tales unearthed by Coulthard' BBC Countryfile Magazine 'A gem of a book' Country Smallholding Without these little engineers of the earth, the world's soils would be barren, and our gardens and fields wouldn't be able to grow the food we need to survive. Worms recycle decaying plants, putting nutrients back into the soil; they provide a food source for wildlife; and their constant burrowing helps heavy rain soak away. Sally Coulthard's fascianting guide offers a wealth of information and practical advice about the world's msot industrious but little understood creature.

Explores the impact earthworms have on the ecosystem, discussing how they improve soil, fight plant diseases, clean up pollution, and turn ordinary dirt into fertile land.
