The problem facing civilization today is rebuilding the soil and restoring the earth to a form usable for food production. Through the slow processes of nature, it takes 500 to 1,000 years to lay down an inch of topsoil. Under favorable conditions, a task-force of earthworms can do the same job in five years.
The soil of the earth is in a terrible state, but steps can be taken to provide a hope for better farming, better crops, and better livestock. George Oliver spent over forty years studying the effect of earthworms on the soil.
These magnificent creatures have been with us since the dawn of time, and the impact they have on all life is truly astounding. Whether you are interested in agriculture, poultry farming or fishing, this book is an excellent resource. Drawing on a lifetime of study, Dr. Oliver does a commendable job of backing up all his information with thoroughly researched facts and figures. This classic text, first published in 1941, has been re-edited for the modern reader.
