zaaidiepte

Zaidiepte is the depth at which seeds are placed in soil during sowing. It is a key parameter in crop establishment, influencing seed-soil contact, access to moisture, temperature exposure, and the energy available for germination and seedling emergence. The appropriate depth varies with seed size and vigor, soil type, moisture, temperature, and crop species and farming method.

If the depth is too shallow, seeds may dry out, be eaten by birds, or fail to form a strong seedling. If it is too deep, germination may be delayed or fail because the seed cannot reach the surface or overcome soil resistance and crusting. Small seeds are generally sown more shallowly, while larger seeds can be placed deeper to reach adequate moisture and give seedlings enough energy to emerge.

Common practice uses a depth roughly proportional to seed size: many guides suggest planting at about one to three times the seed diameter, with smaller seeds placed shallowly and larger seeds deeper into moist soil. In practice, seed depth is governed by sowing equipment, soil moisture, and whether the soil is loose or compact. After sowing, emergence is monitored to adjust future depth and ensure proper soil coverage to maintain moisture and minimize crust formation.

Seeding depth is coordinated with other planting parameters such as row spacing and seed rate, and is influenced by soil texture, drainage, and weather conditions. Accurate setting of zaaidiepte helps improve germination uniformity and crop establishment.
