This book on conservation and improvement of the forest soil
is intended for students at agricultural universities who specialise in soil improvement
and for all readers who are interested in conservation of the forest environment.The development of human society largely depends on the exploitation of the biosphere. Unfortunately, its resources cannot last forever: some may diminish, others may be irreversibly damaged or destroyed. Land and water are among the key resources exploited by man. They are limited and irreplaceable. If degradation, pollution and wastage of soil and water continue, mankind's development may gradually slow down and stop. Farming is intensifymg as also are other branches of the economy, thereby aggravating the factors conducive to erosion.
