Soil types: a field identification guide

This AIDGAP field guide is intended to help students to identify soils in the field in the British Isles. Itcontains two soil identification keys: an introductory soil key which is designed to enable beginners to identify major soil groups; then, a more advanced soil types key to subdivisions of soil types. Rather than disappointing students when they invariably don't find the 'ideal' brown earth or podsol in the field, the keys encourage users to focus on the effects of water movement, aeration and organic matter which can be observed in all soils.
