In the past, the soil was described as heavy or light, sandy, saline, dry or moist, marshy, soft or compact, stony or sedimentary. The weight of an object will change if the object is brought farther. For example, a mass of will have a weight of magnitude. They are related since larger masses will have larger weights due to. how much it resists changes in velocity). Mass is a measure of the inertia of the object (i.e. Soil morphology is a branch of soil science that describes the physical (observational) attributes of soil and its type on the soil horizons using internationally recognized means. Weight is the force of gravity exerted on an object. Organisms such as earthworms play a role in soil formation by opening spaces in the earth crust known as pores and decomposes it in the process. Flowing rivers, on the other hand, transport particles of soil. Rainfall water washes away topsoil in a process known as erosion. Water washing apart exposed soil particles can be in the form of rainfall or flowing rivers. The rocks wear out over time if blown away by wind or transported by flowing water or glaciers and eventually separate to form layers. Several climatic conditions play essential roles in the rate and formation of soil. The initial composition of soil begins from the “parent material” (rocks) which is either below or above the ground level. The process of forming soil is known as pedogenesis. The primary features of soil will take into consideration the size and shape of soil structure, grains, and composition. For example, to classify soil in terms of mechanical properties, permeability, strength, and stiffness will be measured. Soil classification is the arrangement of soil into different classes regarding similarity in characteristics and behavior. The interactions make soil science a very integrated and broad field of study in science. The pedosphere experiences numerous contacts with the atmosphere, biosphere, and hydrosphere. Both divisions address soil physics, chemistry, and biology. The main branches of soil science as indicated above are edaphology and pedology. Soil forms part of the pedosphere (on the Earth’s crust). They include microbiologists, archaeologists, chemists, engineers, and physical geographers among others. In the spirit of not being more negative when referring to others than I would wish to be used when referring to me I suggest inattentive is the correct word. Many professionals have been associated with the field of soil science. Edaphology, on the other hand, is the study of soil effects on living organisms, especially plants. Pedology includes the chemistry of soil formation, its classification, and morphology. Soil science consists of two divisions: pedology and edaphology. It also involves the utilization of soil and soil management.
Soil science is the study of the properties of soil on the Earth’s surface including classification of soil, soil formation, and mapping.
