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.
