J. Jpn. Soc. Soil Phys. No. 33, p../ /.,**/ * * Changes in Chemical Properties and Water-percolation of Soils Overlaid with Cattle Manure Compost Masami NANZYO* and Keiko YAMADA* * Graduate School of Agricultural Science, Tohoku University + +, Tsutsumidori-Amamiyamachi, Aobaku, Sendai 32+ 2///, Japan Abstract An overlay of cattle manure compost, several centimeters thick, on a lowland soil-column with a depth of,. cm, and watering at a rate of -3 mm a day resulted in significant reduction of water-percolation in one or two weeks. With watering, large amounts of dissolved or dispersed organic matter and K were released from the compost. The K was exchanged with Ca, in the soil column and the degree of Ca, -saturation of the organic matter increased with downward movement and the organic matter was retained in the soil. The precipitated or flocculated organic matter with Ca, might have clogged the capillary pores of the soil. Formation of bubbles due to biological activities and swelling of soil colloids with increased K saturation might also have been involved in the reduction of water-percolation. No significant reduction of water-percolation occurred when an Ap horizon soil of nonallophanic Andisol was placed in the column. Ion exchange of Ca, with K proceeded less in the nonallophanic Andisol than in the lowland soil. Aggregates are more stable and bulk density was lower in the nonallophanic Andisol than in the lowland soil. These properties were favorable for the nonallphanic Andisol to keep its high water-percolation. Other changes in soil chemical properties were an increase in labile P and a ph rise. The increase in labile P took place in the upper part of the nonallophanic Andisol column due to its high P retention capacity whereas an increase in the labile P was also observed in the lower part of the lowland soil column.
