Why is proper seed depth important in planting?

Proper seed depth is crucial because it ensures good seed-to-soil contact and allows access to adequate moisture, which are both essential for germination and seedling development. When seeds are planted at the correct depth, they can effectively absorb moisture and nutrients from the soil, which promotes healthy growth. If seeds are too shallow, they may dry out quickly, and if they are too deep, they might struggle to reach the surface or encounter inadequate moisture levels for germination.

While uniform growth is important and can relate to planting depth, the primary factor driving this aspect is the seed's access to moisture and proper embedding in soil. Pest exposure might be a concern but is not directly affected by depth in the same way seed-soil contact and moisture access are. Seedling coloration, although an indicator of health, is not a direct reason for planting at a specific depth. Thus, ensuring good seed-to-soil contact and moisture access is foundational to successful planting practices.
