T problem of drainage in muck or organic soil is not only associated with yield of the crops from these soils but also with the conservation of the soil itself. Preliminary studies of the rate of subsidence, i. e., rate of settling due to oxidation of the organic matter, are here briefly reported along with yields of special crops grown on soil in which the water table was maintained at specified levels. Using the potassium ferricyanide tests for ferrous iron as described by Hoffer (2), the regions of the soil in which aeration had taken place were determined and correlations are drawn between these data and the yield of the crops.
