Seedbed

As a seedbed is called the prepared for sowing farmland. The seedbed should be such that it provides a uniform depth of the seed and the best germination conditions; so it's different for different plant species and seed sizes ( thousand seed mass) and Sämethoden prepare.

On the one hand, the " seed " lie on a sufficiently solid capillary- topsoil, but on the other hand be covered by an easily warmed and well ventilated Locker layer. Special attention in this case requires the seed of Lichtkeimern - to fine crumbling can be used to drift or capping of the soil lead to flat seed easily leads to being eaten by birds.

Usually the soil by plowing a furrow is turned and mixed and under worked aboveground plant residues of the previous crops. This work can only be performed on a previously dried enough farmland to subsequently achieve the desired re-consolidated, but fine crumbly soil structure with other agricultural equipment such as packers, harrows or seedbed.

To soil erosion endangered arable land (eg heavy rainfall, slope ) to protect or maintain soil structure, is also increasingly used the direct seeding. Here the seedbed is the unploughed area harvested the previous field crops.

In an optimally prepared seedbed following zones are clearly visible:

• Loose Oberkrume with a sufficient proportion of fine soil for embedding the seed; coarser aggregates in this zone reduce the Verschlämmungs and erosion risk
• Remote seeding depth ( surface to which the grains come to rest ) with connection to the capillary rise of water from the subsoil for a quick and safe germination
• Unterkrume with a gradual transition to the subsoil; free from condensation, but sufficient reconsolidates (eg, after application by the packer after plowing )

In horticulture comes to small patches scattered before the term seedbed. Because of the widespread here Handsaat and control possible from moisture and heat the specific requirements of each seed can be more easily met.

Not sown but set If plants are one speaks of a planting bed.
