Precision farming

Minimizing fertilizer input whilst maximizing output is a winning strategy from both an economic and ecological perspective.

Yara N-Tester

Remove the guesswork

Nitrogen supply from the soil and nitrogen uptake from the plant vary from year to year. Applying “usual” nitrogen rates remains unsatisfactory in terms of cost, crop yield and quality as well as environmental protection. Determining exact plant needs, however, is not always easy.

The Yara N-Tester is a handheld device, engineered for use in the field. It determines nitrogen requirements in real-time by measuring the chlorophyll content in the leaf. The device is calibrated for winter cereals, but can also be used to test other crops.

Adjust split application

The N-Tester is the ideal companion for split application of nitrogen. The optimum fertilizer supply can be easily determined prior to each application. Measuring a few plant leafs is sufficient to get highly reliable information on the nitrogen status of the plant.

Field tests have proven the capability of the N-Tester to improve the accuracy of fertilizer recommendations. The device thus removes most of the guesswork in farming practice, improving quality, yield and margins while saving fertilizer cost.

Yara N-Sensor

Adjust fertilization rates instantaneously

Nitrogen needs vary significantly across an individual field. Measuring actual crop needs in real-time and adapting fertilization rates accordingly during spreading is the most advanced form of precision farming available today.

The Yara N-Sensor™ is an optical device. It measures light reflectance from the crop canopy in different spectral ranges, using either ambient light (classic N-Sensor ™) or built-in light sources (N-Sensor™ ALS). The system is designed to work continuously at normal tractor speed, scanning the field on both sides of the tractor. The measured reflectance contains information on chlorophyll content and biomass. Both indicators are used to calculate nitrogen uptake and optimum application rates. The information is sent to the spreader controller. Spreading rate is adjusted instantaneously to actual crop needs.

Rely on independent operation

When connected to a GPS receiver, the N-Sensor™ automatically generates maps of crop density, nitrogen requirements and applied fertilizer. Unlike satellite imagining, the N-sensor™ is independent from weather conditions and external data providers, thus offering full control to the farmer.
