Which of the following statements is not correct about soil texture?
Answer Details
The statement that is not correct about soil texture is: "Fine-textured soils are warm soils and coarse-textured soils are cool soils."
Soil texture refers to the composition of soil in terms of the relative proportion of sand, silt, and clay particles. The four options are related to different properties of soil texture.
The first statement is correct; soils with fine particles have a higher water holding capacity than coarse soils. This is because fine-textured soils have more surface area per unit of volume, which allows them to hold more water.
The third statement is also incorrect. Leaching is the process by which water moves through the soil and carries nutrients with it. Coarse-textured soils have larger pores, which allow water to move through them more quickly, resulting in a greater loss of nutrients through leaching than in fine-textured soils.
The fourth statement is correct; fine-textured soils have a higher nutrient holding capacity than coarse-textured soils. This is because the smaller particles in fine-textured soils have more surface area to which nutrients can attach.
In contrast, the second statement is the one that is not correct. Soil texture does not necessarily determine the temperature of the soil. Soil temperature is influenced by many factors, including climate, vegetation cover, and the depth of the soil. Soil color, organic matter content, and moisture also affect soil temperature. Therefore, it is incorrect to assume that fine-textured soils are always warm and coarse-textured soils are always cool.
