Soil:

• Basic chemical properties: active and substitutional pH value, calcium carbonate content, humus, readily available phosphorus and potassium, total nitrogen, and mineral forms of nitrogen.
• Mineral nitrogen in soil for nitrogen fertilization based on the N-min method.
• Total and available content of secondary macro-elements and micro-elements: Ca, Mg, Fe, Mn, Cu, Zn, Co, and B.
• Total and available content of potentially harmful elements: Pb, Cr, Ni, and Cd.

Fertilizers (inorganic and organic), soil improvers, substrates, and organic materials:

• Physical properties: granulometric composition, moisture content, mechanical strength of granules, bulk density, and volumetric mass.
• Nitrogen: ammoniacal, nitrate, amide, and total nitrogen.
• Phosphorus: total, water-soluble, NAC-soluble, and water-soluble.
• Potassium: total and water-soluble.
• Total and water-soluble content of Ca, Mg, Fe, Mn, Cu, Zn, Co, and B, as well as total content of Pb, Cr, Ni, and Cd.
• Content of humic and fulvic acids, organic matter, and organic carbon.
• For substrates, soil improvers, and organic fertilizers: pH value, electrical conductivity, mineral forms of nitrogen, available and total forms of phosphorus and potassium, as well as other nutrient elements.

Plant material:

• Determination of nutrient elements: N, P, K, Ca, Mg, Fe, B, Mo, Cu, Mn, and Zn.
• Results can be used to assess mineral plant nutrition and provide expert interpretation in the context of production.
