The paper deals with of the relations between forest ecosystem, calcareous rocks and content composition soil organic matter in Golo Bardo area West Bulgaria. In that Rendzinas are used mainly for forestry, viticulture pastures. A specific study based on accumulation according to data acids. research provided information course humification processes studied soils. Soil depends different factor...

A better understanding of past climate change is vital to our ability predict possible future environmental dynamics. This study attempts investigate the dynamic features temporal variability peat humification, water table depth and air temperature by analyzing palaeoecological data from Valdai Uplands region (Central European Russia). The regression analysis revealed presence a periodicity abo...

The aim of this study was to describe the processes that control humic carbon sequestration in soil. Three experimental sites differing in terms of management system and climate were selected: (i) Abanilla-Spain, soil treated with municipal solid wastes in Mediterranean semiarid climate; (ii) Puch-Germany, soil under intensive tillage and conventional agriculture in continental climate; and (ii...

Aerobic composting of conventional municipal sludge has always had the problems nitrogen loss and low humification. In this study, biolysed (BS), polyacrylamids-added (PS) Fe (III)/CaO-added (FS) were used for composting, respectively, their effect on physical-chemical parameters, conversion humification during investigated. The results showed that dissolved organic matter (DOM) concentration B...

Dry olive mill residue (DOR), the by-product of the two-phase extraction process, is very rich in organic matter and nutritionally relevant cations. For this reason, the agronomic use of this waste has been suggested although DOR exhibits significant phytotoxicity. The objective of this study was to investigate the impact of Paecilomyces farinosus on both organic mattermodification and detoxifi...
