−1 , dry weight basis) increased the pH of Beaverlodge and Fort Vermillion soils from 4.8 to 6.0 and 5.5 to 6.3, respectively. The higher pH in manure-amended than unamended soils was attributed to buffering from bicarbonates and organic acids in cattle manure. Mineral N (NH4–N + NO3–N), available P, K, Ca, and Mg increased immediately after manure application, and available P and K remained significantly higher in manure-amended than unamended soil after the 8-wk incubation. Soils amended with 40 g manure kg−1 had three to four times more plant-available P and K than unamended soils after incubation. Available S concentrations did not differ significantly in manure-amended and unamended soils. Extractable Al and Fe declined slightly after manure application, but did not differ in manure-amended or unamended soils after incubation. No change in the cation-exchange capacity (CEC) of manure-amended soils compared to unamended soils was observed in this study, and it appears that appreciable changes in Al, Fe, and CEC from manure application do not occur in the short-term (weeks). Our results indicate that, in the short-term, cattle manure amendments can increase the pH and the quantity of plant-available P and K in acid soils.
