Question: Interceptor drain helps to control water logging by:
Options:
A. Lowering the water table
B. Preventing subsoil water from reaching the area
C. Draining out excess water to natural drains
D. Allowing vertical drainage
Interceptor drain is a type of drainage system designed to intercept and divert excess water before it reaches a specific area. In agriculture, it is primarily used to prevent water logging by intercepting subsurface water flow (subsoil water) from uphill areas and diverting it away from the fields.

● Water logging: The saturation of soil with water, leading to oxygen deficiency and hindering plant growth.
● Subsoil water: Water present beneath the surface soil.
● Surface drains: Ditches or channels that collect and remove excess water from the surface of the field.
● Water table: The upper level of the saturated zone in the ground, below which the soil and rock are filled with water.
