Definition of Tilling:
Tilling is the process of breaking up and turning over the soil to prepare it for planting. It involves loosening the soil, removing weeds, and incorporating organic matter to improve its structure and fertility.

Importance of Tilling:
- Improves soil aeration: Tilling helps to loosen compacted soil and create space for air, which is essential for plant root growth.
- Enhances water infiltration: Loosened soil allows water to penetrate deeper into the ground, reducing runoff and helping plants to access moisture.
- Controls weeds: Tilling can help to uproot and control weeds by disrupting their growth cycle.
- Incorporates organic matter: Tilling allows for the incorporation of compost or other organic matter into the soil, which improves its nutrient content and overall health.

Methods of Tilling:
- Manual tilling: This involves using hand tools like spades, hoes, or forks to break up the soil. It is suitable for small garden plots.
- Mechanical tilling: This includes using machines such as rototillers or tractors with plows to till larger areas more quickly and efficiently.

When to Till:
The best time to till the soil is typically in the spring before planting, when the soil is moist but not too wet. Over-tilling can disrupt soil structure and harm soil organisms, so it's important to avoid excessive tilling.
