Bobby A. Stewart - Advances in Soil Science, Volume 7. PDF

PDF With the expanding world population, the major concern just a few years ago was whether the world could produce enough food. Now in many countries agricultural productivity has risen to the point of providing chronic food surpluses while in other areas, notably Africa, food production lags far behind need. In either situation there is a growing concern over managing the soil resource. Concerns range from inappropriate deforestation to depletion to erosion. These concerns are resulting in a shift in research objectives. The need to optimize crop production while conserving the resource base has never been greater. This series of volumes provides a forum for leading scientists to analyze critically the information on a particular subject. Most importantly, contributors develop and identify principles that have practical applications to both developing and developed agricultures.
