GRAINS SEND ROOTS MANY FEET INTO EARTH
Investigators for the Carnegie Institution of Washington have reported some interesting discoveries about the depth to which food plants send their roots. Trees and other perennials send tap-roots to a great distance into the earth, but that cereals, which start new from the seed each season, do the same, has not been generally understood. Professor John E. Weaver reports that in Nebraska wheat and oats were found to send roots down to a depth of from six to eight feet, while corn roots were found eight feet deep. New agricultural methods may result from these investigations.
