There are a variety of free and paid support tools to help make crop nutrition decisions. Please note this is not a complete list. Check out Climate Kelpie for more decision support tools.
Agricultural Risk Management (ARM) Online is a collection of risk management tools including:
- CropARM. Simulate outcomes and risks of different management inputs.
- NitrogenARM. Uses CropARM and soil tests to calculate nitrogen application rates.
- FallowARM. Calculates a range of soil water and N that is likely to accumulate over a fallow period. Data can be used as inputs for CropARM or NitrogenARM.
- ClimateARM. The new version of Rainman. Rainfall and climate analysis.
- Deep-P. Calculate if deep P will provide an economic benefit.
Yield Prophet Lite® estimates crop yield for different rainfall and fertiliser scenarios. It also gives the rainfall likelihood for the remainder of the growing season. Based on the French and Schultz model of water use efficiency.
Australian CliMate asks questions about climate data. e.g. How much water and nitrate have I stored over the fallow? When is the optimum sowing time based on temperature? Also compare this season to previous seasons. Available on web, iOS and Android.
SWApp estimates plant available water (PAW) during fallow and cropping. For iPhone and iPad.
Use Decipher to map and visualise paddock fertility. There is a basic free version of Decipher, as well as paid packages. DecipherGO is the companion app (free, for iPhone and iPad). It uses satellite images to show trends in plant density and growth performance.

Ranking Options for Soil Amelioration (ROSA) is a WA based spreadsheet tool that analyses which soil amendments will give the biggest returns. Contact Jeremy Lemon at DPIRD.
Use MyPaddock to compare different crop production constraints. Input paddock data for management practices, pH, soil nutrition, and compaction.
MySoil summarises thousands of soil types into 15 broad categories. Use it to identify your soil type, the main issues, and why a paddock might not have performed as well as expected.
The Soil water tool graphs how much soil water has accumulated since November 1 and through the grain growing season.
Use the Wheat yield constraint calculator to calculate potential yield and compare this to actual yield.
The Canola diagnostic tool helps identify crop canola constraints.
The Back Paddock system covers both agronomy and economics. Use it to record and report on all client inputs and operations. Share updates easily with clients. Soil Mate offers lab test interpretation and fertiliser advice. Back Paddock also has a range of calculators for soil amendment and fertiliser rates.
Yield Prophet ® helps grain growers match crop inputs to potential yield. It is a subscription service based on the Agricultural Production Systems Simulator (APSIM) model.
iPaddockYield – grower-developed app that forecasts yield throughout the season. Daily rainfall entry updates the potential yield during the season. For iPhone and iPad, available through the iTunes app store ($169.99).
N Broadacre calculates how much nitrogen is available in the various soil N pools. The tool then calculates how much N is needed to reach the crop’s yield/protein target. It is based on DPIRD’s Select Your Nitrogen (SYN) model. On iPad and iPhone ($24.99).
