Vegetation and mulch were collected from a moist and a dry site of a native prairie in eastern South Dakota on September 3 and November 5, 1969 and April 29, 1970 to study the overwinter changes in percent Ca, Mg, K, P, and N. The percent Ca in the vegetation was similar on the three dates for both sites; the percent Mg, K, P, and N in vegetation was greatest on the first sampling date for the moist site. The percent Ca, Mg, and K in mulch tended to be greatest on November 5. The percent P and N varied from date to date. The Ca, Mg, and K leached from the decaying vegetation before November 5 may temporarily have increased the amount in the mulch but it was lost by spring.
