Soil Analysis

The soil analyses laboratory was established in the year 1999, as a development of the chemical foliar and biochemical laboratory.

The following pedological analyses are realized within the laboratory:

• soil pH

• total humus

• hidrolithical acidity

• cationic exchange capacity and base saturation

• granulometrical composition

• nutrient elements accessible to plants: nitrogen, phosphorus, potassium

• soluble salts and acalino-earthly carbonates

• metals: copper, lead, cadmium, chromium, zinc, magnesium, manganese, sodium, calcium, iron.


Besides these, we also realize determinations on foliar samples:

• the determination of chlorophylls

• establishing the percentage of cellulose

• the determination of wood density

• the determination of the existent metals

• nutrient elements


In order to accomplish the analyses mentioned above, the laboratory has modern and powerful equipments:

• spectrophotometer with atomic absorption

• C.H.N. analyzer

• pH-meters

• colorimeter

• automatic biureta

• roasting oven

• water and sand bath

• vacuums

• still

• mills for grinding the soil and leaf samples

• automatic scales with 2-4 decimals

• PC for processing the information


Through the realized analyses, the laboratory contributes to the works realized both by the design community as well as the research one. The obtained data is used for:

• Forest development works, for the proper establishment of the type of station and the correlation between the site quality of the station and the productivity class of the stands.

• The establishment of site quality classes for soils and the necessary of fertilizers, amendments, maintenance works- in the case of nurseries and osieries;

• The forest curtains that protect the communication routes and the field as well as for the afforestation of the degraded fields, the establishment of afforestation formulas, amelioration and maintenance works;

• In the research projects for the identification of macro- and microelements (polluted areas, waste heaps), foliar analyses (impact studies, international investigations) etc.
