Given below are two statements

Statement I: A soil with good tilth is quite porous and has free drainage up to water table

Statement II: The capillary and non-capillary pores should be in a ratio of 1 : 4 so that sufficient amount of water is retained in the soil as well as free air

In light of the above statements, choose the correct answer from the options given below

Solution

While a soil with good tilth is generally well-drained and has good porosity, the extent of free drainage up to the water table depends on various factors such as soil texture, structure, and groundwater conditions. It is not necessary for a soil with good tilth to have free drainage up to the water table. The capillary and non-capillary pores in the soil play a crucial role in water movement and retention. Capillary pores are smaller pores that retain water against the force of gravity, while non-capillary pores are larger pores that allow for free movement of air and drainage.
