Effect of animal manures on selected soil chemical properties (1)

Abstract

The effects of animal manures on selected soil properties were studied in the laboratory. Manures of Rabbit (RBM), Swine (SWM), Poultry (POM), Goat, (GTM) and Cow (COM) were added at 10, 20, 30 and 40 t/ha to an acidic Ultisol. The amended soils were incubated at 70% water holding capacity for 3 weeks. The treatments increased soil pH with POM and SWM having the greatest effect followed by RBM, GTM and lastly COM. Animal manures also reduced exchangeable acidity and increased exchangeable Ca and Mg. With the exception of GTM, all the other manures did not improve soil organic carbon.
