Influencing potato dry matter content

Dry matter content is important for both fresh market potatoes and potatoes destined for processing. Tubers with a dry matter above 18-20% tend to be more susceptible to bruising and tubers disintegrate more readily when cooked.

However, for processing high dry matter content is required to achieve a good fry color and often 20-25% is specified. Nitrogen, potassium and magnesium can all have influences on tuber dry matter content.
