Abstract

The establishment of perennial pasture grasses in nutrient-poor soils requires appropriate soil amendments and fertilisation. The impact of microbial consortium inoculant (either alone or together with rock mineral fertiliser) in growth of five perennial grasses was greater in low-phosphorus soil than high-phosphorus soil. Pasture grasses required low rates of phosphorus and potassium fertilisers, with no evidence of exudation of carboxylate contributing to mobilisation of these nutrients. Pasture grasses showed little dependency on arbuscular mycorrhiza for nutrition and growth, likely due to grasses having thin roots.
