- Traditional method with chemical extractants:  Suitable for the vast majority of outdoor agricultural crops with mineral or organic soil fertilization.  Standard analysis with determination of:  pH (in H 2 O), pH (in KCl), EC,  macro- and micronutrients: NO 3 , NH 4 , P, K, Ca, Mg, SO 4 , Na, Cl-, Fe, Mn, Zn, Cu, B. The extractant solutions commonly used for the different elements are: CaCl 2 for K, Mg, NO 3 and NH 4 , NaCl Solution for Ca, Water for SO 4 , Na and B, Cl-, DTPA / CaCl 2 Solution for Fe, Mg, Cu and Zn, Sodium Bicarbonate Solution-Method Olsen for P.   

Optional: Organic Matter Analysis, Total Kjeldahl Nitrogen, Cation Exchange Capacity,% Base Saturation, Particle Fraction, pH in CaCl 2 ,  Bicarbonates, Molybdenum, Silicon, Acidity and Exchangeable Aluminum.  At the customer's request, the analysis can be carried out with Ammonium Acetate extract (K, Mg, Ca), Mehlich III Solution (P, K, Mg, Ca, Fe, Mg, Cu, Zn) and Bray Solution I (P) .
