IUNG-PIB is conducting soil properties analysis in all Experimental Farms for nitrogen, phosphorus, potassium, pH and Soil Organic Matter content. The data are necessary for nutrients balance performance on a farm and the assessment of Soil Organic Matter in soils cultivated in different systems.
Moreover, IA-PAN is collecting soil samples at the depths of 5, 15, 30, 50 and 70 cm using soil cylinders to measure soil hydro-physical properties (retention curve, hydraulic conductivity in the saturated and unsaturated zone) and also in disturbed conditions to measure such properties as granulometric distribution, bulk density, total porosity, carbon content, and pH. Soil samples are gathered three times per year - in the beginning, in the middle and at the end of the vegetation period.
