A fuel gauge is a strip in the paddock (typically 2m x 100m) containing a non-limiting rate of a specific nutrient. 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 and allow Summit Area Managers to measure nutrient response against farmer practice. Once applied, the strips are read throughout the growing season with a GreenSeeker® and results calibrated using N-Calc software. N-Calc can predict the potential yield loss from not applying nitrogen, and the effect on protein from applying extra nitrogen.

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 - because remedial action can be carried out within the season. Potassium, phosphorus and other nutrient fuel gauges can also be carried out, with responses actioned for the following season.

Setting up a Fuel Gauge
