Physical Soil Amendments, Soil Compaction, Irrigation, and Wetting Agents in Turfgrass Management I. Effects on Compactability, Water Infiltration Rates, Evapotranspiration, and Number of Irrigations¹

Unamended soil and soil amended with peat, lignified redwood, and calcined clay were used to grow common bermudagrass in a greenhouse experiment. Two compaction treatments, 2 wetting agent treatments, and 2 irrigation programs were superimposed on each of the soil materials for a total of 32 treatments. Water infiltration rates were in the general order of unamended soil < peat < lignified redwood = calcined clay amended soil. Compaction decreased the infiltration rate of unamended and peat amended soil, but had no effect on the other two soil mixes. Wetting agent increased the infiltration rate into unamended soil. Soil compactability was in the order unamended soil > peat > lignified redwood > calcined clay amended soils. Soil compactability was greater under set schedule irrigation as compared to tensiometer guided irrigation. Wetting agent reduced the compactability of peat. Evaportranspiration and number of irrigations were greater under set irrigation as compared to tensiometer guided irrigation. Other results of this experiment will be presented in subsequent papers.
