| Abstract/Contents: | "This study was conducted to compare various orchard groundcover management systems (GMSs)--including a crownvetch "living mulch" (CNVCH), close-mowed (MWSOD) and chemically growth-regulated (GRSOD) sodgrasses, pre-emergence (NDPQT) and two widths of post-emergence (GLY 1.5 and GLY 2.5) herbicides, hay-straw mulch (STMCH), and monthly rototillage (tilled)--during the first 6 years in a newly established apple (Malus domestica Borkh.) planting. Mean soil potential at 5 to 35 cm deep varied substantially among treatments each summer, and treatment x year interactions were observed. During most growing seasons from 1986 to 1991, soil water availability trends were STMCH > NDPQT > GLY 2.5 > GLY 1.5 > tilled > GRSOD > MWSOD > CNVCH. Soil organic matter content increased under STMCH, CNVCH, and MWSOD and decreased under NDPQT and tilled treatments. Water infiltration and saturated hydraulic conductivity after 4 years were lower under NDPQT and tilled, and soil under STMCH and GRSOD retained more water per unit volume at applied pressures approximating field water capacity. Mid-summer soil temperatures at 5 cm deep were highest (25 to 28C) in tilled and NDPQT plots, intermediate (22 to 24C) under GRSOD, and lowest (16 to 20C) under CNVCH and STMCH. These observations indicate that long-term soil fertility and orchard productivity may be diminished under pre-emergence herbicides and mechanical cultivation in comparison with certain other GMSs." |
