The different types of analysis menus, as well as their prices, can be consulted on the soil sampling sheet. This duly completed form will accompany the samples taken in the analysis laboratory. After receiving the samples, a 2 weeks delay is required for the analysis of the agronomic parameters, 3 weeks for the metallic trace elements. The analysis bulletins are communicated to you by mail. Once the advice is delivered, our services are at your disposal for any further information. For the cbr testing this is essential.
Metal trace elements: Cu, Ni, Pb, Zn, Cd, Cr, Hg

Soil texture
The Agricultural Analysis Laboratory Center processes about 1000 soil samples per year for granulometric analysis requests. Of these, 50% come from professionals in the sector.
The grain size analysis of soil allows determining the texture of the soil. It is the weight distribution of the mineral constituents of the soil (clay, silt, sand), classified in order of size. This particle size results in a set of properties those results in a particular behavior of the soil (heavy soil, light, moist, draining, flapping). The levy is a key step, not to be overlooked, for obtaining quality advice. This must be representative of the plot to be sampled. A maximum area of 5 he will be recommended in a homogeneous plot for a sample. The laboratory offers different analysis menus to meet your needs:
Soil Physical Analysis: Water pH, organic carbon (humus),% clays,% fine silt,% coarse silt,% fine sands,% coarse sands, flotation index
Sand physical analyzes: determination of the various particle size fractions – 50-100 μm- 100-200 μm-200-500μm-500-1000μm-1-2 mm and> 2mm.
The different types of analysis menus, as well as their prices, can be consulted on the soil analysis sampling sheet. This duly completed form will accompany the samples taken in the analysis laboratory. After receipt of the samples, a period of 3 weeks is required for the analysis.
Residual Nitrogen Mineral / Spring Profile
The Agricultural Analytical Laboratory Center processes about 3000 soil samples per year for requests for analyzes of residual mineral nitrogen and spring nitrogen profiles. Of these, more than a third emanate directly from farmers.
These analyze concern agricultural professionals. Farmers use this tool to:
To adapt their nitrogen fertilizer for spring profiles, for both economic and environmental reasons
To monitor the post-harvest nitrogen balance (APL) on their plots
The removal of residual mineral nitrogen is a difficult step that requires sampling at depths of 2 to 3 horizons of 30 cm. Once the samples have been taken, they must be sent directly to the laboratory and stored in a cold room at less than 4 ° C, for a maximum of 5 days, in order to guarantee the quality of the analyzes. These are the things that you have to keep in mind, and that is the reason that you will need to have a proper idea for the same right there.
