The Influence of Various Factors on the Content of Starch‐free Substance in Potatoes. The influence of Substances containing nitrogen, phosphorus and potassium, which are present in potatoes because of various manuring conditions, on the total content of starch‐free matter in potatoes has been examined. It was found that those manuring conditions, which change the content of substances containing nitrogen, also influence the content of starch‐free substances. The effect of phosphorus is considerably less perceptible. The least influence on the content of starch‐free substances is exerted by potassium. The amount of starch‐free substance is steadily decreasing during the whole course of the vegetation period.
