Abstract
Abstract A scheme, recently introduced in New Zealand, for generating phosphorus fertiliser recommendations estimates the amount of phosphorus nutrient needed to be applied to maintain the size of the cycling pool constant. This scheme was extended by developing an integrated model of pasture response/utilisation and animal production to determine the most profitable long-run combination of fertiliser application and animal output. The economic consequences of imperfect information about the parameters were analysed.
