Soil Bulk Density and Soil Moisture Calculated with a FORTRAN 77 Program

摘要

The paper presents an improved version of BDEN, an interactive computer program written in FORTRAN 77 that will calculate soil bulk density and moisture percentage by weight and volume. Calculations allow for deducting coarse fragment weight and volume. The program will also summarize the resulting data by giving the mean, standard deviation, and 95-percent confidence interval for one or more groupings of data.
