Physical-chemical properties: texture, pH, carbonates content, organic matter, salinity. Nutritional status (N, P, K, S, Ca). Specific chemical properties: cation exchange capacity, buffing capacity
Characterization of soil organic matter: physical fractions (granulometry, densimetry), and / or biochemicals (acid hydrolysis, alkaline extraction, quantification of humic / fulvic acids and humine acids).
Quantification of weakened (fractions), recalcitrant and refractory fractions. Biochemical characterization: carbohydrates, polyphenols, aromatic C forms, lipids. Quantification of forms of C by NMR.
Evaluation of biological fertility: microbial activity under standard conditions (respirometry), microbial biomass.
Nutrient content: basic (N, P, K, Ca, etc.) and micronutrients (Fe, Cu, Zn, etc.). Contaminants: Heavy metals (Cd, Cr, Pb …).
Biochemical characterization: water-soluble, lipids, hemicellulose, cellulose, lignin, total amount of carbohydrates, total phenols.
Physical characterization (sifted, granulometric fractionation). Chemical characterization: content total of N, P, K.
