Potatoes (Solanum tuberosum) belong to the nightshade family. They are exceptionally well adapted to our temperate climate, though they do not tolerate frost and the water demand is relatively high. An even distribution of rainfall is needed to achieve high yields. With sufficient rainfall (>160l/m²) and good distribution in the months from May to August, yields of up to 50t/ha (approx. 20t/acre) can be expected.
Potatoes do not prefer any particular soil type. They thrive in both sandy and heavy soils. The best soils for potatoes are high in organic matter and loose soils with sufficient water retention capacity. Depending on the variety and purpose (starch, table or seed potatoes), this crop is very adaptable. They are planted early in the year (end of March to mid-April) and the soil should be as dry as possible. The seedbed should be finely crumbly and dry to a depth of 10-15cm. The ideal plant density at 75cm row width and 40-44cm placement distance in the row is 30,000-33,000 plants/ha(12,150-13,360 plants/acre).
