Extract

1. Data are presented to show that, in the United Kingdom, soil temperatures do not fall more than a few degrees below freezing point even during prolonged spells of abnormally cold weather.

2. Two methods of assessing cold resistance in cereals are described in which the natural gradient between air and soil temperature is maintained. These involve the use of seed boxes 6 in. deep in one case and a portable field freezing cabinet in the other.
