3. What is a cultivator and why do farmers use it?A cultivator is a machine that prepares a fine seedbed after plowing. It breaks up clods, levels the ground, and helps control weeds, making it easier for seeds to grow.
4. How do the tines of a cultivator work on the soil?When a tractor pulls the cultivator, the tines press into the soil, breaking up clods and increasing pore space. This lets air and water move through the soil better.

Secondary Tillage: Operations performed after primary tillage to refine the seedbed, conserve moisture, and control weeds.
Soil Aggregates: Clumps of soil particles held together by organic matter and other binding agents.
Hardpan: A dense, impermeable layer in the soil that restricts root growth and water penetration.
