Earth Science In Agriculture And Soil Structure

Earth Science in Agriculture and Soil Structure Student NameInstitutionCourseInstructorDateSoilSoil is described as the loose upper material covering the large land portion inclusive of the earth’s crust (Rodrigo, Senciales, Cerdà, & Brevik, 2018). Consisting of organic and inorganic materials, soil provides anchorage and supports agricultural plants through providing water and nutrients as the key necessities for growth. In the topmost layer of soil, a dark brown material containing a combination of plant remains and rock particles ensures continuous penetration of atmospheric oxygen. Furthermore, the SOM is regarded as the biologically active part of the soil with a porous medium with several micro-organisms (Rodrigo, Senciales, Cerdà, & Brevik, 2018). The presence of living organisms in the soil structure necessitate the biological functions which manufacture relnecessitatesiable nutrients for agricultural and all types of plants. For instance, the cycling of carbon and other nutritional elements is facilitated through the active soil medium. Soil structure modification occurs by weathering process driven gradually through biological, climatic and geo-topographical activities hence the reason why soil structures differ in properties with time. The duration of weathering defines difference in soil properties. “Soil geography shares sources
