Abstract

A 2-year field experiment was conducted on a high country brown stony soil in the Lees Valley, North Canterbury. Two forms of lime ('AgLime' and 'Quicklime') were applied at 4 rates (0, 2, 4 and 8 t/ ha) and plots sown with 'Grasslands Kaituna' lucerne. Soil pH was strongly (R2=0.73) related to exchangeable aluminium (Al), with a sharp rise in plant-available Al levels below a pH of 5.8.
