Growth of Avena sativa L. and Agrostis tenuis Sibth was measured on peat and mineral soils from sites on Campbell Island in the New Zealand subantarctic. For the peat soils, growth was strongly positively correlated with both pH and Mg levels and less strongly with Ca and Na. With the inclusion of the mineral soil data, only the fit between growth and Ca levels was significant.
