Nutrient performance indicators for the Australian grains industry

This project aims to develop and test a process to measure and report the nutrient use benchmarks partial nutrient balance (PNB) and partial factor productivity (PFP) for N, P, K and S for grain production systems against which growers can assess their nutrient management practices. These metrics will be derived at national, agroecological zone, regional and farm levels using published and surveyed information.

Overview Fertilizers are a critical input to productive and sustainable farming and their effective use supports economic, social and environmental outcomes. While there are guidelines on nutrient best management practices using the principles of 4R nutrient stewardship (the Right source, applied at the Right rate, at the Right time and in the Right place), there are few metrics that can be used at a field, farm or regional scale to assess the effectiveness of those practices.

Nutrient Use Efficiency on Grain Farms
A GRDC Supported project


Interpretive Summary

2016

With financial support from the Grains Research and Development Corporation, data were collected from five years of cropping from over 500 cropping fields in south-eastern Australia. Crop yield, residue management and fertilizer use were used to estimate removal and use of nitrogen (N), phosphorus (P), potassium (K), and sulfur (S) in aggregate from the field over the study period.

2015

IPNI in collaboration with Southern Farming Systems (SFS) and GRDC, conducted a benchmarking project to identify how efficiently farms in the southern grain growing regions are utilizing N, P, K, and S. This project aims to develop and test a process to identify nutrient use benchmarks using partial nutrient balance (PNB) and partial/total factor productivity (PFP) against which growers can assess their nutrient management practices.
