Nitrogen measurement in plant and soil samples

Controlled fertilization is more productivity, more quality and greater respect of the environment!

The N-Tester ® operates by optically measuring the chlorophyll content of leaves which is strongly correlated to the nitrogen content of the plant. Thanks to this simple process the N-Tester is the most used management tool in FRANCE (over 1400 units to date).

When it comes to soil sampling, our professional samplers use a revolutionary auger created and patented by AGRO-systems that can simultaneously sample up to 3 horizons: the AGRO-Probe ® A3H. This tool obtains samples of the highest quality and reliability. The AGRO-Probe ® A3H coupled with NITRALAB® means that you too can obtain reliable analysis of soil nitrates in the field.

Residual nitrogen

Among the various mineral resources, the remaining nitrate is the most variable. In the soil profile it is a residual stock of nitrogen. To determine this accurately, it is imperative to analyze the soil after winter leaching and at three horizons: 0-30 cm, 30-60 cm and 60-90 cm.
