A second 90 day incubation experiment investigated changes to soil available P and sorption-desorption across variable rates of amendments (0-50 g kg-1). Results showed that alum amendment at a rate of 50 g kg-1 decreased soil CaCl2-P and Olsen-P concentrations by 91.9% and 57.8%, respectively. However, Olsen-P increased when the dolomite rates were 10 g kg-1) could sorb more P in comparison with alum when P concentrations were increased. The P status of the amended soil was closely connected to the P sorption mechanisms on mineral am
