Characterization аnd Grouping by Content аnd Composition of Humus in Bulgarian Soil, through Mathematical аnd Statistical Methods
Keywords:
humus type — humic, humic-fulvic, fulvicAbstract
By application оf mathematical аnd statistical methods in the development of analytical data for the composition of humus in soils of Bulgaria is proposed classification of humus into six types and therefore grouping оf soils according to the humus type: 1) Humus of Chernozems, Vertisols, Rendzinas (Rendzic Leptosols); 2) Humus of Albic Luvisols; 3) Humus of Planosols; 4) Humus of Cambisols (Mountain Brown Forest Soils); 5) Humus of Umbric Leptosols (Mountain-Meadow Soils); 6) Humus of Gleysols (Hydromorphic Gleysols).
