Adaptingsome machines already tn normal farms, the saH is pressed only by a few passages;by one passage 2-3 works are dane: (a) planting + fertilization,(b) ploughingtharoughly ridging herbicidation ar phytosanitary controls, (c) ploughingthoroughly + ridging + suplemrnentary iertilisation between rows. By hand aredane only filling the planter and lifting up the tubers aHer their digging byMSC-l.BEITRĂGE ZUR FESTLEGUNG DER KARTOFFELBAUTECHNOLOGIEAUF GENEIGTEN BODEN UNTER VOLLMECHANISIERTEN BEDIN­GUNGEN MIT WENIGEN ARBEITGĂNGENZUSAMMENFASSUNGAui den Băden welche gunstige Bedingungen fUr die Kartoffeln augweisen,kann dor Anbau mit guten Ergebnissen aui geneigten Hăngen van 12-14° Meigungsgradausgedehnt werden, mit der Bedingung dass a11e Arbeiten mit entsprechendenMaschinen und in der Schichtlinie orientiert, durchgefUhrt werden.
