Description of the types of sowing when changing the earth-boards.
1. Sowing into tracks - Earth-board Delta, most useful for wide spectrum of cereals - rape, pea, corn
Ploughless sower sows the seed into 15 cm broad tracks, in accurately set depth. Upright and horizontal spreading levels the land, straw, clod and stone cumulates into 10 cm broad room between trails. The seed lies on bare capillary, it is not in intercourse with straw and it's inhibitory influence is so restricted to minimum. This provides accurate depth of sowing and at the same time undercutts the soil horizon (sharing).
