Question 6. It is very thick in lowlands but very thin on highlands. Composed of clays to a greater extent. Aquatic plants that float on water are called _____ plants. Soil minerals are divided into three size classes — clay, silt, and sand (Figure 1); the percentages of particles in these size classes is called soil texture. It is made up of extremely fine clayey materials. (ii) It is smooth to touch. Answer: (i) It is mixture of both sand and clay particles and has air spaces. Thus, the soil can be classified as sandy, clayey and loamy. Wind blows loose soil off flat or sloping land known as wind erosion. The Whately series consists of very deep, very poorly drained soils that formed in a thin mantle of loamy outwash materials over clayey marine or lacustrine deposits on lakes and marine plains, and outwash plains and deltas. Consistence is firm in place, friable when removed and sticky when wet. In damp places in Fynbos, you will often find small plants called Sundews. Clay soils feel very sticky and rolls like plasticine when wet. Soil containing 80% silt is called silty. Identifying clay soil is relatively easy to do. of big particles it is called sandy soil. Plants that grow in swampy areas give out _____ roots to absorb air. It is poorly aerated because the tightly bound clay particles leave little space in between to trap air. So, during the dry season, these soil develop wide cracks. It has the capacity to hold moisture for a long time. This helps in the aeration of the soil. They are most co… Its water holding capacity is very high. Pedology is … Soil Soil is the thin top layer on the earth’s crust comprising rock particles mixed with organic matter. Due to the strong physical properties of clay, a soil with only 20% clay particles behaves as sticky, gummy clayey soil. Wet Consistence: Historically, moderately sticky was called sticky. This process is called leaching. Clayey Soil 1. Also, Soil Taxonomy is not the reference we use since “The Field Book for Describing and Sampling Soils” was published. Effects: Makes land unsuitable for cultivation. Clayey soil, therefore, gets easily water-logged. Aquatic plants that have their roots fixed to the bottom of the pond are called _____ plants. Land so developed is called bad lands, in the Chambal basin they are known as ravines. When a small insect like an ant or fly lands on the leaf, it cannot escape from the sticky liquid. Question 6: List the differences between clayey soil and sandy soil. The mineralogy of soils is diverse.

Now, do you mean clay soil, or do you mean - where can we find usable clay? This soil has very good water storage qualities and makes it hard for moisture and air to penetrate into it. These soils are also known as the ‘Regur Soil’ or the ‘Black Cotton Soil’. Clay is the smallest particle amongst the other two types of soil. Earth's body of soil, called the pedosphere, has four important functions: . If the proportion of fine particles is relatively higher, then it is called clayey soil. However, because of the small size and surface area of clays, most of the water in a clay soil may not be avail-able to plants. Clayey soil is rich in organic matter. Soil retains water and becomes sticky and wet. The clay contains a high proportion of chalk pieces and occasional flint stones. They have a high water-holding capacity. If the proportion of fine particles is relatively higher, then it is called clayey soil. (iii) Water cannot pass through it, so it holds lot of water and becomes sticky. Wet clay soil is heavy and sticky, and tends to swell from the added moisture. However, clayey soil is rich in a mineral which makes it suitable for plant growth. It has the largest particle among different soil particles. Clayey Soil. Soil texture—The textural designation of a soil is determined by its relative portions of sand, silt, and clay particles, and indicates which of the three most influence the soil's properties. 5)Water drains out very slowly through clayey soil which can lead to water-logging of soil and damage the crop plants.

Kankar (calcareous concretions) beds are present in some regions along the river terraces. Over 25 percent of clay these soils are made and clayey soil holds a high amount of water because of the spaces found between clay particles. To overcome this problem, plants here have breathing roots to absorb air. Question 6. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. It is very sticky to the touch when wet, but smooth when dried. Plants that grow in water are known as _______ plants. Clay soil: Clay is composed of very fine particles that become heavy and sticky when wet--and hard and concrete-like when dry. These soils are found in the north- … The mean annual soil temperature is about 76 degrees F. The organic matter decreases irregularly with increasing depth. Loamy Soil. Clay soil can look different in different places, but it usually acts the same way: it tends to be slow to drain, quick to harden, and difficult to use for anything but the hardiest plants. These small particles mix with humus (organic matter) and form soil. A sticky, bluish-gray subsurface layer of clay found in some waterlogged soils. Black soil is called black soil fire. If the amount of large and fine particles is about the same, then the soil is called loamy. It is sticky when wet, it can be rolled, it can be smeared easily and it can be smoothed into a shinier finish. Clayis a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO2), metal oxides and organic .
