Progress in Soil Mixing for Nematode Control

Progress in Soil Mixing for Nematode Control REPRINT WEST OF SCOTLAND AGRICULTURAL COLLEGE PROGRESS IN SOIL MIXING FOR NEMATODE CONTROL BY JOHN GRAINGER (West of Scotland Agricultural College, Auchincruive, Ayr.) Cysts of Heterodera rostochiensis have been found at depths from 28 to 36 in. (71 to 91 cm.) in potato land in west Scotland (O'BRIEN and PRENTICE 1932). The vast majority, however, are present in the top 8 in. (20.3 cm.) of soil. Now the top 8 in. from one acre would form a large heap 25 by 10 by 4 yds.
