A fuel gauge is a strip in the paddock (typically 2m x 100m) containing a non-limiting rate of a specific nutrient (most often nitrogen). They can be carried out across a wide range of crops.

A strip of non-limiting nitrogen has been applied in-season, to measure the potential benefit to the crop.

Key Benefits of Using Fuel Gauges

Fuel gauges are a useful way of in-season nutrient monitoring. Once applied, the strips are assessed throughout the season with a Greenseeker®. The data is then analysed using N-Calc software. The nitrogen rich fuel gauge strip is compared to the growers crop and used as a calibration tool to predict the required rate to be applied, and the potential yield loss from not applying additional nitrogen to the paddock.

This information will allow you to make better decisions regarding your in-season fertilizer applications, with the aim of maximizing yield and profit.

Types of Fuel Gauges

The majority of fuel gauges are nitrogen however potassium, sulphur and phosphorus fuel gauges can also be carried out.

Setting up a Fuel Gauge

Summit Area Managers have access to the right technology and equipment to conduct fuel gauges and are able to read, assess and interpret the results. If you are interested in setting up a fuel gauge on your farm, or would like to learn more, contact your local Area Manager.
