Indeks trofizmu gleb lesnych

The paper presents a digital valorisation of soil trophism based on easily accessible properties. This method results from a soil skeleton, silt and clay part percentage share, reaction, base exchangeable cations sum and the organic matter decomposition rate. The above-mentioned properties have been assigned numbers from 1 to 10 but soil skeleton from 0 to 5 in proposed ranges. Totals of the above numbers decreased of soil skeleton index and calculated weighed means in profile constitute Forest Soil Trophism Index (ITGL). This method serves soils trophism valorisation as well as soil and forest sites classification.
