Harvest mechanization in winter beet [in the south of Spain] | Mecanisation de l'arrachage de la betterave automnale

The fall planting sugar beet harvest is made during summer, the climatic conditions and type of soils, loosing the moisture very rapidely, and not being possible in many cases to irrigate to make softer the soil. Harvest machines usually used in spring planting areas, have a different performance, mainly in lifting and cleaning of roots. Lifter has much more difficulties to penetrate in a dry and hard soil. Roots are soil free but aggregates of clay with same texture of beets make difficult the separation of both. Percentage of aggregates is relatively low, but is very appreciable and psychologically important for the growers. The circumstances have supposed a delay in the integral mechanisation of the beet harvest cultivated in winter. The use of stage harvest machines, have been, and in many farms are still a solution. Lifted beets are laid on the harvest row, a row in between is prepared by passing a roll, and finally beets are by hand located in the new row. We present the studies made by AIMCRA since 1988 oriented to make possible the mechanisation of the crop in the south of Spain, by reducing the cost of hand labour and also the soil labour in extremely dry condition during summer.
