Abstract

The MAF Fertiliser Advisory Service provides fertiliser and lime recommendations for pastures, lucerne and cereal crops. It does this by combining farm details with an understanding of the behaviour of nutrients in soils, plants and animals derived from many years of soil fertility research. Recommendations are for individual farms or blocks of land. Balance models are used in which fertiliser requirements are calculated to replace nutrients lost from cycling pools via animals and within the soil. Soil tests assess the influence of previously applied fertilisers and are used to modify recommendations. A technical report showingfertiliser options is prepared for advisers while short and long term recommendations are given in a more basic report addressed to the farmer. Keywords: Fertiliser recommendations, soil testing, pastures, cereals, lucerne.
