Laterite soil The Laterite Soil is the type of soil formed from intense leaching in areas of high rainfall , moisture and high temperature. The soil formed by the process of intense leaching is laterite soil Q19. Name the process by which laterite soil is formed. Mention one disadvantage of the soil. Answer: Laterite soil is formed by leaching. Leaching is a process by which the nutrients of top soil are washed away. One disadvantage of this soil is that, it is very acidic in nature and cannot retain moisture. Q20 For instance, sandy soils are normally cemented by iron. Here, the soil drainage and air space will depend on the resultant soil type and the compaction and cementation process. Factors That Affect Soil Formation.

The adjectival form of a class name of rock fragments or pararock fragments (table 3-2) is used as a modifier of the texture class name, e.g., paragravelly loam, very cobbly sandy loam. Table 3-3 provides rules for determining the proper texture modifier term for material with a mixture of rock fragment sizes Methods of soil conservation: 1. Contour ploughing: Ploughing along the contour lines can check the flow of water down the slopes. It is called contour ploughing. It can be practised on the hills. 2. Terrace cultivation: Steps can be cut out on the slopes making terraces. It restricts soil erosion. It is practiced in western and central. Soil formation is a long slow process. It's estimated that an inch of soil takes 500 to 1000 years to form. Soil is constantly being formed. It is also constantly being eroded. At this time the little pockets of soil have formed to the extent that some larger plants, plants with roots can have a go at growing

Chlorophyll is the foundation site for the photosynthesis in green plants. The initiation of photosynthesis takes place when the chlorophyll molecule traps the light energy. The light energy is then converted into chemical energy in the form of glucose using carbon dioxide (CO 2) from the atmosphere, and water (H 2 O) from the soil. All other. Class 10. PRMO NTSE The oxygen present among the soil particles diffuses into the root hairs. From root hairs, oxygen is transported to all the parts of roots for respiration. In the plants taking herbaceous stem exchange of gases occurs through stomata and the carbon dioxide CO 2 formed during the process that gets diffused into the. Aggregate formation is a complex process. Soil aggregates are formed through physical, chemical and biological activity below ground. They are even influenced by human factors, like tilling, walking on the surface, or even how you fertilize your garden. Formation of aggregates begins with finer soil primary particles binding together Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological and anthropogenic processes working on soil parent material.Soil is said to be formed when organic matter has accumulated and colloids are washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum, producing a distinct layer called the B horizon Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier).If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment

The soil is formed by the mixture of minerals, organic matter, gases, liquids, and many organisms, air and water, etc There are three main classifications of rock, based on the way the rock was formed: sedimentary, metamorphic and igneous. Soil is formed of fine rock particles mixed with air, water and particles from dead plant and animal matter. There are three main types of soil which are classified according to the amount of sand and clay in them. Top 10 fact It is commonly referred to as sub-soil. B-horizon is a zone where fine material is accumulated by percolating water. In some soil B-horizon is enriched with calcium carbonate in the form of nodules or as a layer. It has the same color and texture throughout its depth. The thickness of this horizon is 25 - 30 cm but it may range from 10 to 240 cm

3. Soil Atmosphere: Gases found in soil profiles are said to form the soil atmosphere which is one of the most important components of the soil. The spaces between soil particles and soil organisms are called pore spaces. These are filled with moisture and air in varying quantities which account for approximately half of the total volume of soil It looks yellow when it occurs in a hydrated form. Laterite Soil ; The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain. Humus content of the soil is low because most of the microorganisms, particularly the decomposers, like bacteria, get destroyed due to high. A sticky soil, such as clay or silt; its shear strength equals about half its unconfined compressive strength.Soil in which the absorbed water and partical attraction act such that it deforms plastically at different water Contents are known as Cohesive soils or clays. These soils possess higher plasticity . e.g. clays & plastic silt. 10
