CHANGES IN THE CONTENT OF PHENOLIC ACIDS IN LOOSE SAND AND BROWN SOIL FERTILISED WITH SOIL FROM SUGAR-PROCESSING PLANT SEDIMENTATION TANKS

ABSTRACT



A single dose of 10, 25 and 50% (weight percentage) of the soil collected from sugar-processing plant was added to loose sand and brown soil. A four –year - pot experiment was set where the following were cultivated, in turn: corn, buckwheat, spring wheat and corn. It was observed that the content of phenolic acids in soil grew proportionally to the dose of soil introduced and it was positively correlated with the contents of C-org, N-org, available P, K and Mg forms, floatable forms and sorption capacity, as well as the plant yield and its nitrogen and magnesium contents. However, the content of phenolic acids in brown soil did not show a linear dependence on the sediment dose, it correlated negatively with the amount of C fraction most susceptible to biological oxidation and with microbiological respiration activity, yet positively with the concentration of potassium available in soils, yield and its nitrogen content.

Key words: phenolic acids, soil derived from sugar-processing plant sedimentation tanks, soil fertility, brown soil, loose sand.
