Abstract

Icicles visible in photo above, were hanging from lettuce plants that had been sprinkled for frost protection by ice-coating. Photo to right, above, shows ice beginning to melt off the frost-protected lettuce heads. Right photo shows lettuce plants on a 24-inch grid, coated with ice. Lower photo to right shows uniformity of lettuce heads produced on flat soil surface with grid system. Photo below shows alfalfa plants encased in one-half inch of ice for frost protection.
