to consolidate the efforts of the Bulgarian scientists
in the field of the theoretical and applied humus substances research.
The main goal of the Bulgarian chapter of IHSS is to consolidate the efforts of the Bulgarian scientists in the field of the theoretical and applied humus substances research.
This website presents information about Bulgarian Humic Substances Society (BHSS) – chapter of International Humic Substances Society (IHSS). The society was founded in 1997. At present, BHSS has a membership of 64 scientists and specialists. Individual members of IHSS – Bulgarian Chapter have a membership of 34 scientists. They are scientists and specialist from research institutes, Universities and private firms.
The scope of scientific interests includes:
structure, properties, and genesis of humus substances
interactions of humus substances with heavy metals
application of humus substances for land reclamation
biological activity of humus substances;
technologies of manufacturing and agricultural applications of humus substances
humus state of Bulgarian soils, etc.
Crop residue decisions affect soil life
The results convinced the audience that straw is not a waste but a valuable product. it must be plowed (incorporated) into the soil that plant residues are a source of energy and nutrients. They support biodiversity management and create opportunities to improve soil fertility. The burning of plant residues leads to a decrease in soil organic matter in the humus horizon, and as is well known, the formation of humus takes hundreds of years.
