How is clayey soil useful for crops? The ratio of these particles in any given soil sample identifies it as one of the three main types of soil: sandy, loam or clay. 1. Particles are of quite large size. The proportion of tightly packed fine particle of this soil is higher. Depending on the composition of these elements, the soil’s texture and composition is determined. This provides high water retention capacity. Sandy Soil. 2. List the differences between clayey soil and sandy soil. Since, paddy requires lot of standing water, therefore it is grown in field B. 1.Proportion of big particles is large. If the proportion of the finer particles is relatively higher, then it is called clayey soil. The following are the differences between the clayey and the sandy soil. Clay also forms spaces between the particles, so holds nutrients and water in much better than sandy soil. Farmers often talk of light soil and heavy soil. Also, clayey soil is rich in humus and is very fertile. Clayey Soil. The particles are irregular in … Solution: Clayey soil retains water to a great extent. Water can drain quickly. Clay soil responds differently to water, has a unique texture and affects the roots of garden plants in a way that other kinds of soil do not. Allow the pat to dry by oven, sun or air. With a wet clay soil, the producer or gardener must wait longer for the soil to dry sufficiently. Q5: List the difference between clayey soil and sandy soil. This soil can hold a good amount of water and thus the draining speed of the water is quite slow. Clayey Soil. 28). 4. Answer: Clayey soil is useful for the crops because Question 9. Answer: Sandy soil: Clayey soil (i) High percolation rate. Thus the crops which require more water grow well in clayey soil. List some uses of clayey soil. In any soil that is not dominated too much by sand, silt or clay, approximately half the soil volume is pore space. Question 2: The water holding capacity is the highest in (i) sandy soil (ii) clayey soil (iii) loamy soil (iv) mixture of sand and loam. List the differences between clayey soil and sandy soil. Sand does not hold water due to the fact that sandy soils have greater (and larger opening type) porosity. 8 Guide students to figure out which soil particle­ clay. 7. There are lots of variations of these soil types Answer: (ii) Clayey soil . The soil is found in layers, which are arranged during the formation of soil. Particles are of very small size. Sandy soil has anything from 80-100% sand in it while clay soil is anything from 50-100% clay.

Loam soils also contain anything from 30-50% of silt. 2. Question 6. For example, root crops, such as carrots and onions, perform best in a sandy soil because it is loose and allows the plants to expand. Between the sand, silt and clay particles there are lots of pores. Soil. The way the other particles combine in the soil makes the loam. The strength is tested by breaking and crumbling the dry pat between the fingers. Soil texture may limit which crops can be grown. Answer: Clayey Soil: Loamy Soil (i) It has much smaller particles. These layers called horizons, the sequence of layers is the soil profile. 2. (iv) Air content is low. Water retention capacity of the clayey soil is quite high. What processes does formation of soil involve? 5. Sand is grainy and is not very good at absorbing water, so the soil is light and drains well.
