Total sulfur and its fractions as well as activity of arylsulfatase in soil depending on waste organic materials and liming

100%

Kalembasa S. , Godlewska A.

2010

tom Vol. 36, nr 1

5-11

Soil samples were collected after the 4th crop of grass in the second year of pot experiment, in which the influence of liming (according to 1 Hh) and organic fertilization (sewage sludge and poultry droppings) were examined. Total sulfur content and its fractions (in the form of SO4(-2), available sulfur, and sulfur from humus compounds) were determined in soil samples. The organic materials applied caused a significant increase in total sulfur content in the soil and considerably increased the amount of sulfur in organic compounds. Liming did not exert any influence on total and available sulfur content, while it decreased the level of sulfur in humus compounds. Arylsulfatase activity in the soil significantly depended on the organic material and liming applied.
