Soils, Land and Food

the long version

"The book leads the reader through the development of techniques of land management and discusses reasons why some agricultural projects have succeeded while others have failed. It shows how surveying and protecting soils before new land is brought into cultivation, raising soil fertility, increasing inputs and improving economic conditions can all help to increase food production. Particular emphasis is placed on the need for both economic change and technological innovation in developing countries where, in many cases, food production will need to more than double in the next 50 years."--Jacket.
