Wind-Blown Soil Abrasive Injuries to Winter Wheat Plants1

  1. N. P. Woodruff2



Winter wheat plants were given fall and spring exposures to blowing soil in a wind tunnel. Average yields, weights of plant material, and number of heads for spring treatments were 46.4, 29.4, and 23.9% less, respectively, than fall treatments. Heading and ripening of grain was delayed 1 week to 10 days on severely exposed plants. The total amount of soil striking a plant was more important in depressing products of plant growth than was the length of time between exposures. The plants were shown to have remarkable recovery powers if given water after severe abrasive injury.
