Precision management makes it possible to align cultivation intensity with demand and thus adjust expenses to the necessary level. The proportion of normal-sized, marketable commodity – i. e. size grade 40 to 60 mm – can thus be increased in potato growing too. Planting distances adapted to the soil properties seem to achieve this objective. Yields could be improved further, especially in intensive potato-growing regions where irrigation and fertilizing already contribute to a consistently high yield potential in the rather light soils. Different planting distances on individual soil plots were tested in the authors’ own trials. Planting distances of 31.50 cm in light soils, 24.50 cm in medium soils and 27.50 cm in heavy soils produced the best results. Both the overall yield and the proportion of marketable goods were improved.
