The Influence of Sugar Factory Waste Lime and Phosphogypsum upon Selected Chemical Properties of an Acid Semigley
The goal of the investigation was to evaluate the sugar factory waste lime and phosphogypsum in terms of correction of excessive soil acidity. Materials were applied in two doses accounted according to the neutralizing index of each material. Waste materials applied were sugar factory waste lime (15 and 30 t/ha) and phosphogypsum (12.5 and 25 t/ha) and they where compared with hard limestone (6 and 12 t/ha). Chemical soil properties were influenced strongly according to the dose and kind of applied material. According to the changes of soil pH, hydrolytic acidity, basic cation saturation percentage and mobile aluminium content, sugar factory waste lime was the same or slightly better than the conventional liming materials represented by the hard limestone. Sugar factory waste lime influenced rise of soil pH from 3.8 to 4.7 in lower dose, and up to 5.6 in higher dose. Phosphogypsum application had no influence on soil pH in the case of lower dose (pH 3.9), while in the higher dose change was small (pH 4.1). Results shows that sugar factory waste lime can by used as a liming material with similar influence on the listed chemical soil properties as conventional liming materials. Phosphogypsum application was practically without significant influence on soil pH and with relatively small influence on hydrolytic acidity and base saturation level. Phosphogypsum can cause a decrease in mobile aluminium content, but phosphogypsum cannot be as effective as conventional liming materials.
