One of the most important books about soil ever written. It should be thoroughly studied by anyone seeking a full understanding of soil fertility and how to handle agricultural soils. This is a scientific text that can be understood without high level maths, however, a well grasped secondary school science education and a touch of geology will go a long way towards making this book fully comprehensible. Dover has published a paperback reproduction of the original 1941 McGraw-Hill printing that sells for a very modest price. Missing from our Soil and Health Library online copy will be the modern Forward in the Dover edition, which is copyrighted material.
