D2-Lanca«ter Farming, Saturday, May 4, 1996 COLUMBUS. Ohio Severe cases of frost heaving damaged many Ohio alfalfa fields during the winter, and in some cases completely destroyed plant stands, said an Ohio State University for age agronomist. Mark Sulc said that some fields have plant crowns as much as 4 to 6 inches above the ground, with taproots completely broken. The hardest hit were stands newly seeded last August, although dam age also occurred in established stands. “It appears that most areas of the state suffered from some heav ing,” Sulc said. “The degree of heaving varies from field to field, and even varies within individual fields." Sulc said that frost heaving also damaged red clover and birdsfoot trefoil in some areas. The chief cause appeared to be high levels of soil moisture freez ing throughout the winterwhich expanded the ground and uplifted plants, Sulc said. Upon thawing, the soils subsided to original levels, leaving plant crowns exposed and root systems severed. Gandy Has Positive Displacement!

Frost heaving appeared to be a winter-long process, followed with multiple freeze-thaw cycles of warm days and cold nights into the spring, Sulc said. The latter cycles raised plants even higher above the ground, severely damaging plants not anchored into the soil. Although silty, poorly-drained soils are most susceptible to frost heaving, Sulc even saw damage in tiled fields. Damage also varied within individual fields depending on snow cover, residue cover and plant vigor. “However, the overriding factor appeared to be soil moisture con tent, because good residue cover did not reduce heaving in wetter portions of fields,” Sulc said. Sulc said farmers need to walk their fields because damage is often not visible from the road. Farmers should evaluate damage depending on whether the field Distributed Bv Also Dealer For Airstream Helmets G.S.I. BINS & Fill Systems LIFETIME HYDRAULIC TRAILERS (610) 285-6519 was newly seeded last August or if it was an established stand. In any case, farmers should not roll or cultipack soils of newly seeded or established stands. Those practices will cause more harm than good, he said. Fields that have heaved one half inch or less should recover whether they were newly seeded last August or were older, estab lished stands. Continue to monitor these fields for recovery through AAA VENTILATION LIFETIME GUARANTEE spring. Delaying harvest may help with recovery in both cases. Newly seeded fields with more serious damage can be reseeded this spring. Autotoxicity, which occurs when older stands release LAND PRIDE H SOLID FEATURES...
