Soil science deals with the study of edaphic conditions as they relate to the production of food and fiber. Soil science is also a constituent of the field of agronomy and is thus also described as soil agronomy. Soil fertility refers to the ability of a soil to sustain agricultural plant growth and to provide plant habitat and result in sustained and consistent yields of high quality. The soil fertility should be able to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and the absence of toxic substances which may inhibit plant growth. Soil fertility should have a sufficient soil depth for adequate root growth and water retention. This session discusses the latest developments in soil science and soil fertility.
