A humic fertilizer containing humic and fulvic acids was extracted from lignite. The effects of the extractants on the yield of extraction and on the characteristics of humic acids were investigated. The following extractants were used: ~1, 0"25, 0"5 and 1"0 M KOH and ~1 M NaOH. Acid pretreatments

The effect on barley growth of humic substances extracted from municipal wastes with different degree of stability was studied. This effect was compared with that of the humic substances extracted from organic materials used in industry to obtain humic acids (peat and leonardite). The humic substanc

The rate of extraction of tnacylglycerols with supercntical carbon dioxide can be greatly enhanced by raising the pressure of the fluid to 600 bar, or higher, and its temperature to 60Β°C, or higher. Both the amount of carbon dioxide and the time required for complete extraction are reduced at such h
