| Abstract/Contents: | Article is in two parts. First is an outline of organic (peats, sawdust) and inorganic amendments available and the characteristics to look for when selecting them. The second part is a reprt on the Penn State Soil Modification Project. Begun in 1960, the field evaluation involves 81 mixtures. Materials used in the field are identified as well as their source. Components of the test were outlined; establishment of plots, compaction and aerification treatments, measurement of soil physical properties, percolation and infiltration rates, bulk density and porosity, available and unavailable water. Coarse sand and turface ranked highest in effectiveness for increasing soil permeability of compacted mixtures, followed by Wunderley and USS Slags, concrete and mortar sand. Perle-loam was least effective in study. The coarser textured mixtures exhibited greater resistance to compaction than did finer textured mixtures. Aerification appeared to be an essential practice with some mixtures to make them acceptable for intensively used turf areas. Permeability decreased over the years and the magnitude of change affected by the mixture as well as by compaction and aerification. Over time, physical properties of soils receiving compaction from maintenance operations approached those of soils more severely compacted with a compaction machine. Resistance of coarser mixtures to compaction was seen in wider differences in soil permeability and air porosity between compaction treatments. |
