Geosoil Laboratory

Our Geosoil Laboratory Is There to Support You Throughout Your Agronomic Management Process

We achieve the accreditations for agricultural soil analyses required by our governments. Whether they are analyses to complete your agro environmental fertilization plan (Nutrient Management Plan or NMP), analyses of the soil of your fields, manures, lime, slurry and fertilizers, or even to adjust your applications according to the variability of your soils through precision agriculture, our laboratory is there to meet your needs.

As an affiliate of Synagri, Geosoil Laboratory performs its analyses independently. All your information and all your results will remain confidential and only be sent to you or to the designated recipients. Professionalism is one of our most important values.
