Chemical composition of soils: role in soil health Yinglong ChenIntegrated nutrient management systems that use a holistic approach, using inorganic fertilizers as well as management practices aimed to increase soil organic matter, are needed to improve soil health. Management practices need to take into account differences in soil properties, climate and available local resources. In this chapter, we discuss the chemistry of nutrients focusing mostly on nitrogen and phosphorus. The impact of chemical composition
