Abstract:
     For the purpose of getting fine and soft soil on the land-surface a new method of cultivation and a combined soil preparation-machine are invented. Through the soil crushing bolter, special root smashing knife-teeth and rotary ploughing knife-teeth of the machine the roots and soil are thrown back-ward and crushed by the soil crushing bolter. After the fine soil-granules have been screened off the lumps of soil, which are uncracked by the bolter are thrown back again to repeat the above-mentioned method until the soil on the land-surface is fine enough for planting.
