Abstract

Three liming experiments were established to confirm previous estimates of the critical soil acidity level for barley. Two experiments studying the effect of depth of incorporation on the effectiveness of lime, established in 1986, were continued in 1987.
The results from the three liming experiments established this year supported the conclusion that barley is affected by soil acidity at pH's around 4.2 and 4.3 (CaC12) and that depth of this acid layer is important.
Significant lime responses were obtained at the Katanning depth of lime incorporation site but conclusions can not be made because of possible mixing of acid and less acid layers further down the profile at the deeper depths of incorporation.
