This is a standard net mineralization study. Plots were laid out on a 30X30 meter grid within stands representative of the dominant vegetation at the sites listed. Cores were taken randomly from within the plots at the beginning and the end of each month, and analyzed according to the methods listed below.

From the sites mentioned, once per month we took sixteen cores (7.3 cm dia. X 10 cm) in pairs of eight. One core from each pair was brought back to the lab and extracted in .5 M K2SO4 and the extracts frozen for later analysis. The other cores were bagged in polyethylene bags and reinserted into the ground. About 30 days later these cores were retrieved from the field and brought to the lab for extraction in .5 M K2SO4 and the extracts frozen for later analysis. All extracts were analyzed on a technicon autoanalyzer for NH4+, No3-, and by the ninydrin technique for total amino acids, expressed as leucine equivalents.
