11026. Anon.. 1990. Lime application - no-till/minimum till in the PNW.. Bumper Times Special Edition, Spokane, WA. 1/31/90, p. 3.
Dr. Tim Murray, WSU, found that increasing soil pH in the top 3" of soil lowers cephalosporium stripe potential. At pH 5.6, wheat infection was 80% and it declined steadily with liming to just 10% at pH 7.0. About 2.5 tons/ac high grade lime is required to modify pH from 5.3 to 6.0 in Palouse soils.
