Aluminum in acid soils and the factors controlling its behavior are detailed in a second article. A third long review explains the role of nutrient management on water quality, which is now a critical issue for environmental conservation. The final chapter is a definitive treatise on interparticle force effects on physical behavior of soils, which has crucial influences on plant growth and yield.
