The use of a rotary harrow is recommended for soil cultivation. This deposits all coarser pieces of vegetation and stones a little deeper and creates a fine, crumbly seed bed on the surface.
In so-called threshing, grains are removed using a mechanical process when harvesting threshing fruits. The chaff and grains are then separated:
If the harrow is not sufficient to control weeds, the use of a hoeing device is recommended.
The following video shows a test harvest - this is done with a plot harvester. The samples are then examined and the data evaluated.
And another experimental harvest - this time the mowing is done with a motor mower.
A cupping cut is usually carried out after the grassland seed has emerged in order to disrupt the development of unwanted herbs and to stimulate the tillering of the grasses.
