It becomes sticky in the rainy season and develops cracks when dry. The clayey soil (having the lowest percolation rate) retains the highest amount of rainwater in it. The clayey soil consists of very fine particles of clay. 7) Loamy soil contains sufficient amount of humus. Clayey Soil 1. Question 6 How will you calculate the percentage of water in a soil? The large spaces between sand particles are filled with air. Fill a measuring cylinder with water. Secondary School. (4) For growing cotton crop, ‘sandy-loam soil which drains water easily and can hold plenty of air in it, is more suitable. In the snow covered areas of Himalayas, which of the following soil experiences denudation and is acidic in nature with humus content? They are well-known for their capacity to hold moisture. These soils are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime but are deficient in phosphoric contents. 4) Sandy soil has large particles with large spaces between them. The humus makes the soil fertile and provides nutrients to growing plants. The water vapour coming out of the soil reflects the sunlight irregularly due to which the air above the soil seems to shimmer. 17 Very Sticky . adding some sand and humus (manure) to it.

Water is usually present as a thin film around the soil particles. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. The percolation rate of water is expressed in the unit of millilitres per minute which is written in short form as mL/min. Due to this, clayey soil is used to make pots, bricks, toys and statues. The difference in the mass of soil ‘before and after drying’ will give us the mass of water (or moisture) present in the original mass of soil taken. When water is poured over soil, then some of it gets absorbed in the soil and the rest passes down the soil. Area with lot of water and sticky soil are called Share with your friends. View in context In the nature of the land, however, around Maldonado, no such reason is apparent; the rocky mountains afford protected situations; enjoying various kinds of soil; streamlets of water are common at the bottoms of nearly every valley; and the clayey nature of the earth seems adapted to retain moisture. The best soil for growing wheat crop is,  loamy soil. 3. clayey. Though soil usually contains some water (or moisture), it can still absorb (or soak up) a lot of water. So stabilization of the expansive soil is necessary. Soil is affected by the climatic factors such as wind, rainfall, temperature, light and humidity. This soil retains moisture and becomes very sticky when wet. 10) Sand will improve the drainage of clayey soil whereas humus will provide it the necessary plant nutrients.

Clay particles (being much smaller) pack tightly together leaving little space for air. 0 ; It is called clay soil. This air provides the oxygen required for respiration by the roots of plants and other organisms (which live in soil). The process in which water passes down slowly through the soil is called percolation of water. Economics Chapter 3 Money and Credit – Notes & Study Material, Compounds of Xenon and uses of Noble Gases, Characteristics and Physical Properties of Group 18 Elements, Oxoacids of Halogens and Interhalogen Compounds, English Alphabets with Phonics Pronunciation, Economics Chapter 2 Sectors of the Indian Economy – Notes & Study Material. a sticky, putty like feel indicates a high % of which soil seperate. 0 ; Clay soil. 1.7. 4)The excess water can also drain out through it easily. 0 Please find this answer. 2) Loamy soil is a mixture of large and small rock particles which impart it the desired properties. On a hot summer day, this water of soil evaporates to form water vapour. The process in which water passes down slowly through the soil is called, The percolation rate of water is expressed in the unit of, All the plants growing on the surface of earth are called. 2) Clayey soil is very compact. Soil textural triangle . Paddy also requires a lot of irrigation water afterwards. This will give us the original mass of soil taken. The percolation rate of water in a soil is the volume of water in millilitres which passes down the soil per minute. The climatic factors as well as the type of soil determine the type of crops and other vegetation which can grow in a region. Unless otherwise stated, colors in the descriptions are for dry soil. Some of the important crops and the types of soils which are suitable for growing these crops are given below: (1) Clayey soil and loamy soil are both suitable for growing cereals like wheat, and gram (chana). All the plants growing on the surface of earth are called vegetation. 6) Sandy soil provides good aeration (air) to the plant roots and it can be ploughed very easily. Clay particles can be found in some form or another in many striations, and they appear in most parts of the world. The sandy soil (having the highest percolation rate) allows the rainwater to reach a well faster and in greater amount. • They swell when wetted and shrink when dried, so a certain amount of restructuring can take place in these soils depending on weather conditions. ¾Very Sticky - soil adheres firmly to both fingers after release of pressure with stretches greatly on separation of fingers. Though water can percolate through all types of soils but the rate of percolation of water through different types of soils is different. • The laterite soil develops in areas with high temperature and heavy rainfall. This study presents the review work on clayey soil stabilized with different stabilizers (i.e. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. 4) Clayey soil is heavy because it can hold more water than the sandy soil. Paddy (rice crop) is planted in standing water in the fields. 2) Sandy soil contains very little humus. Your IP: 138.197.137.228 ).The soil is stabilized with different percentages of FA, RHA and Lime. 11) Clayey soil is very sticky. See answers. (iii) Loamy soil It is a mixture of sand, clay and silt with a small amount of humus in it. The percentage of water (or moisture) in the given sample of soil can then be calculated by using the formula : Percentage of water in soil =( Mass of water in soil / Original mass of soil) × 100. Suitable for crops like paddy, wheat and gram. The settling of particles in a soil suspension.

In India, extensive deposits of black soil are found in the Deccan Plateau which includes parts of Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh, parts of Tamil Nadu. Share 0. However, if the cor-rect size, uniformity and quantity of sand is used, soil physical properties can be improved. At the place where percolation rate of water is to be measured, dig the soil to a depth of about 2 cm in the ground. Mineralogical composition of soil (area within the figure denotes the relative abundance of minerals) Fig. en ‘Fränkischer Spargel’ is produced in the areas of clayey ground that are typical of Franconia and in the sandy soils of the Jura, the hills and Keuper rock strata of Northern Bavaria, the Franconian Plain, the Spessart and the area around the Rhön at an average height of 200 to 300 metres above sea level. It contains very little air. They become sticky when wet and develop cracks on drying up. 9) Clayey soil is more fertile than sandy soil. 6)Loamy soil can also be ploughed easily.

There are mainly three basic types of soils. Black Soil Black soils are mainly found over the Deccan lava tract (Deccan Trap) including Maharashtra, Madhya Pradesh, Gujarat and Andhra Pradesh. So, the percolation rate of water is lowest in the clayey soil. 1)Sandy soil is quite loose, so the percolation rate of water is highest in sandy soil. 5) A disadvantage of sandy soil is that it cannot hold much water in it because the water gets drained out quickly through large spaces between its particles. Your email address will not be published. 5) Loamy soil has also adequate air spaces between its particles to hold sufficient air needed by plant roots. 1) Loamy soil is a mixture of sand, clay, silt and humus in the right proportions.
