importance/application of seedbed/objective of seedbed/significance of seedbed

1.loose and smoothed  soil:
 The soil of a seedbed needs to be loose and smoothed, without large lumps.
2.increase germination:
  These traits are needed so that seeds can be planted easily, and at a specific depth for best germination and also increase germination rate.

3.removal of debris. Insect eggs 
The removal of debris. Insect eggs and disease spores are often found in plant debris and so this is removed from the plot. Stones and larger debris will also physically prevent the seedlings from growing.

4. Levelling:
The site will have been levelled for even  irrigation and drainage purpose.
5.Breaking up the soil:
Breaking up the soil. Compacted soil will be broken up by digging. This allows air and water to enter, and helps the seedling penetrate the soil. Smaller seeds require a finer soil structure. The surface the soil can be broken down into a fine granular structure using a tool such as a rake.
6.Soil improvement.
The soil structure may be improved by the introduction of organic matter such as compost or peat.
7.Fertilizing
Fertilizing. The nitrate and phosphate levels of the soil can be adjusted with fertilizer. If the soil is deficient in any micro nutrients, these too can be added.
