  • Dispersive Soil Essay

    777 Words  | 4 Pages

    The soils that are highly susceptible to erosion and containing high percentage of sodium ions are called “Dispersive soil.” Dispersivity is the property of soil by virtue of which soil separates into their component particles when wet. Soil dispersivity is due to the presence of exchangeable sodium present in the structure. Dispersive soils are structurally unstable soils. In appearance, dispersive clays are like normal clays that are stable and somewhat resistance to erosion, but in reality they

    Soil erosion is a growing problem worldwide and has been taken its toll on the environment. Although soil seems insignificant to the population, it is a viable source that humans need to survive. Soil anchors all life on Earth by providing plants with the nutrients needed to stay alive. Not only does it play a key role in the design and sustainability of agricultural systems but it also affects future generations needs and production of crops as well (Higgit 1). Soil erosion affects the global community’s

  • Soil Nutrition In Plants

    Upton 14310368 C. ‘In order to understand the geography of soil all one needs is a good map of the solid geology.’ Abstract: It would be naïve to assume that a good map of solid geology is the only resource needed to understand the geography of soils. The geography of soil does not depend solely on the solid geology of the biosphere and lithosphere. When one studies the geography of soil it is important to look at the properties of soils including the parent material which is usually the dominating

  • Essay On Soil Salinity
