The water holding capacity is the highest in
(i) Sandy soil
(ii) Clayey soil
(iii) Loamy soil
(iv) Mixture of sand and loam
Correct answer: (ii) Clayey soil
Explanation: The water holding capacity is the highest in clayey soil because it is made up of very small tightly packed particles that do not allow water to percolate.
[Extra information: Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. It is formed from the breakdown of rocks into tiny pieces called sediments. These rocks are broken down through the process of weathering due to exposure to extreme temperature changes, windblown particles, precipitation and flowing water, and ice.
Soil are generally classified into the following:
1. Clay soil is defined as soil that is comprised of very fine mineral particles and not much organic material. The resulting soil is quite sticky since there is not much space between the mineral particles, and it does not drain well at all.
2. Sandy Soil contains a high percentage of sand or large soil particles. Water travels through sandy soil very easily, so nutrients leach out quickly.
3. Loam soil contains more nutrients, moisture, and humus than sandy soils. They have better drainage and infiltration of water and air. They are easier to till than clay soils. Loam soil is suitable for growing most plants.
