Claas’ ISARIA N sensing system is now Isobus ready

Claas’ ISARIA optical N sensing system has achieved Isobus accreditation masking it available to fit any Isobus ready tractor.

Claas’ distributor, Landpower group product manager, Luke Wheeler, said Isobus provided confidence about the operational reliability of the farming technology.

“This ‘plug and play’ technology means producers and contractors can standardise the operating systems of all of their machinery, regardless of manufacturer.”

The company’s ISARIA optical crop sensor system enables the variable application of fertilisers, growth regulators and other crop protection products based on measured nitrogen uptake in crops.

The system calculates the crop’s nitrogen requirements, determines the optimum application rate and then adjusts the fertiliser spreader in a single pass.

The system features two sensor heads, fitted on an aluminium frame mounted to the tractor's front linkage to measure the infrared light reflected from the crop.

“This provides a measure of the amount of nitrogen uptake in the crop,” mr Wheeler said.

“ISARIA then compares this measurement with the target value and calculates the optimal application rate after adjustment for crop density, biomass and crop calibration.

“The application rate can also be adjusted for yield potential using a map overlay system.

“These algorithms are based on more than 20 years of research.

“The system ensures maximises crop potential by optimising nitrogen availability but without over-application, reducing input costs, saving time and protecting the environment.”

The sensors take up to 500 measurements per second, with the frequency automatically adjusted to the prevailing conditions.

The system is also fitted with LED lighting, allowing it to be used at night. The lightweight unit can be mounted to a front linkage in just a few minutes.

“ISARIA can be controlled using the Claas CEBIS terminal or any other Isobus compatible device,” Mr Wheeler said.
