What is the purpose of tilling soil before planting?

Tilling soil before planting primarily serves the purpose of preparing it for seed planting. This process involves turning and loosening the soil, which enhances its structure and aeration. By breaking up compacted layers, tilling allows for better root penetration and improves water infiltration, creating a more conducive environment for seed germination and growth. Additionally, tilling can help incorporate organic matter and nutrients into the soil, further supporting healthy plant development.

While options like removing nutrients or promoting weed growth may occur incidentally after tilling, they are not the primary reasons for this practice. Similarly, compacting the soil contradicts the objectives of tilling, as the goal is to create a loose, well-aerated environment rather than a compacted one. Therefore, the correct answer emphasizes the key role of tilling in seed preparation, ensuring optimal conditions for planting.
