The depth of sowing can have a significant impact on seed germination. Different seeds have different requirements for depth of sowing, depending on their size, shape, and other factors. In general, larger seeds can be sown deeper than smaller seeds, as they have more stored energy and can push through more soil to reach the surface.
If seeds are sown too shallowly, they may dry out or be eaten by birds or other animals before they have a chance to germinate. On the other hand, if seeds are sown too deeply, they may not have enough energy to push through the soil, or may not receive enough light or warmth for germination.
The ideal depth for sowing seeds depends on the specific crop and the conditions in the field. In general, seeds should be sown at a depth that allows them to make good seed-to-soil contact, but not so deep that they are unable to germinate. A general rule of thumb is to sow seeds at a depth that is two to three times their diameter.
It is also important to consider soil moisture when determining the depth of sowing. If the soil is too dry, seeds may need to be sown deeper to reach moisture, while if the soil is too wet, shallow sowing may be more appropriate to prevent the seeds from rotting.
Overall, careful consideration of the depth of sowing can help ensure good germination and healthy crop growth.
Each edible plant that has its seeds sowed on different soils must have the safe place determined in the soil profile to allow uniform germination in short periods. Sandy soils suggest deep safe place in contrast with clay ones. Weeds, medicinal herbs, flowers, and other species that requires light or irrigation can germinate on the soil surface. The rules for seed germination is a source of information for professionals of agriculture to make precise decisions. Furthermore, the latitude and altitude of the crop field has influence on the soil temperature. Other variables may also have influence in the results from seed sowing. Walter.
Light plays a crucial role for seedling survival for light demanding species. As the seed moves deeper in the soil, Red/far red light ratio goes down. Therefore, far-red conditions may affect germination of some species.
