Why is tilling of the soil carried out before sowing seeds?

Tilling, also known as ploughing, is a crucial preparatory step that transforms soil into an ideal environment for seed germination and plant growth. This practice serves multiple essential purposes that directly impact crop success.

When farmers till the soil, they break up compacted earth, creating a loose and aerated structure that allows plant roots to penetrate deeply and spread efficiently. This loosening process also improves soil porosity, enabling better water infiltration and retention—critical factors for seedling survival. Additionally, tilling brings nutrient-rich deeper soil layers to the surface while burying weeds and crop residues, which decompose and add organic matter back into the soil.

The process also helps in pest management by exposing soil-dwelling insects, larvae, and their eggs to predators and harsh weather conditions, naturally reducing pest populations. Furthermore, tilled soil warms up faster in spring, promoting earlier germination. By mixing in organic fertilizers and manure during tilling, farmers ensure even distribution of nutrients throughout the root zone, giving seeds the best possible start for healthy crop development.
