Extract

The dry-matter content of about 260 samples of potatoes was determined. The samples were collected over three seasons and from many types of soil.

The average dry-matter content of a variety varied from season to season, but it always bore an approximately constant relationship to the average value of other varieties.

Wet seasons led to potatoes low in dry matter.

The variation in the content of dry matter of potatoes in different seasons and from different soil types is not a direct effect of the water balance of the tubers.

The average content of dry matter of potatoes depends on the soil in which they were grown; fen and blackland gave potatoes with the lowest dry matter, followed by skirt, silt and warp, then loam and medium loam, then clay, and the highest dry matter occurred in stocks grown in sands, gravels or light loams.

The difference between the soils is discussed, and it is tentatively concluded that the factor responsible for the variation in content of dry matter of the potatoes is the available water content of the soils.
