• The N Sensor ALS was awarded the RASE Gold Medal in 2008
• Cereal yields increased by 3.5% where the same intensity of fertiliser was used
• Oilseed yields increased by 3.9% through the Absolute-N calibration
• Nitrogen savings of up to 14% have been recorded where N Sensor was used
• Increases in nitrogen use efficiency have reduced the carbon footprint by 10-30%
• Combine performance was increased by 12-20% due to reduced lodging, lower losses, and
faster intake speeds
• Protein levels in cereal crops showed greater consistency averaging 0.2-0.5% above target
• An 80% reduction in lodging rates (compared with crops where nitrogen was applied under
conventional practices)
Find out your own farm feasibility to see how much your farm can gain from using the Yara N-Sensor.
Site Specific fertilisation is one of the main objectives of precision agriculture. Variable-rate nitrogen applications requires accurate and efficient tools to determine the crops nitrogen status.
Remote sensing techniques offer the opportunity to this information quickly and precisely. The Yara N-sensor has been developed to determine the crop nitrogen status by measuring the chlorophyll level of the plant and apply the correct amount of nitrogen to each part of the cropped field without over or under applying.
The N-Sensor determines the nitgogen demand by measuring the crops light reflectance covering a total area of approximately 50m2 / sec. Measurements are taken every secound with the system designed to operate at normal and all bout widths. Most sensing technology applied to agriculture is based on typical light reflectance cure for vegatation (NDVI). N-Sensor measures light reflectance at specific wavebands related to the crops chlorophyll content and biomass. It calculates the actual N-uptake of the crop. Optimum application rates are delivered from the N-uptake data sent to the controller of the variable rate spreader or sprayer which adjusts the rate accordingly.
