Soil and fertilizer analysis laboratory

Services

A / ANALYTICAL SERVICES

• Soil analysis

Physico-chemical properties: texture, pH, carbonate content, organic matter, salinity. Nutritional status (N, P, K, S, Ca). Specific chemical properties: cation exchange capacity, buffering capacity.

Characterization of soil organic matter: physical (granulometry, densimetry) and / or biochemical fractions (acid hydrolysis, alkaline extraction, humic / fulvic and humic acid quantification).

Quantification of labile, recalcitrant and refractory fractions. Biochemical characterization: carbohydrates, polyphenols, aromatic C forms, lipids. Quantification of C forms by NMR.

Assessment of biological fertility: microbial activity under standard conditions (respirometry), microbial biomass.

• Plant analysis

Nutrient content: basic (N, P, K, Ca, etc.) and micronutrients (Fe, Cu, Zn, etc.). Pollutants: heavy metals (Cd, Cr, Pb…).

Biochemical characterization: water-soluble, lipids, hemicelluloses, cellulose, lignin, total carbohydrates, total phenols.

• Analysis and characterization of mineral fertilizers

Physical characterization (sieving, particle size fractionation). Chemical characterization: total content of N, P, K. Other nutrients: Ca, S, etc. Evaluation of solubilization rates and availability: experiences of successive washes, evolution within the soil, incubation experiences in controlled or semi-controlled conditions.

• Analysis and characterization of solid organic fertilizers: peat and compounds

Elemental analysis (C, H, O, N). Basic nutrients: phosphorus, sulfur, potassium. Micronutrients and heavy metals.

Wealth in humic substances. Physical properties: water retention capacity, porosity.

• Analysis and characterization of liquid organic fertilizers: liquid humus and biostimulants

Elemental analysis (C, H, O, N). Nutrients (P, S, K, Ca). Wealth in humic fractions. Salinity.

Detailed biochemical characterization: carbohydrates, lipids, phenols, protein, amino acids.

B / SCIENTIFIC-TECHNICAL ADVICE

Experiments to evaluate the usefulness of products in controlled conditions (laboratory studies), semi-controlled (greenhouse) and field studies (experimental fields). Development of arguments for the sale of products, depending on their physical properties. chemical. Adaptation to current regulations in the EU and other markets (USA, Canada, Australia, South America, Asian markets). Testing and development of new products.
