TY - JOUR T1 - Reduction of Oak Chlorosis with Wood Chip Mulch Treatments JF - Arboriculture & Urban Forestry (AUF) JO - JOA SP - 275 LP - 278 DO - 10.48044/jauf.1990.061 VL - 16 IS - 10 AU - E.B.

Watson Y1 - 1990/10/01 UR - http://auf.isa-arbor.com/content/16/10/275.abstract N2 - Wood chip mulch and ammonium sulfate treatments around urban white oaks (Quercus alba) were associated with favorable changes in soil properties. Bulk density and pH were lower, and moisture content was higher under the mulch. Fine root development and number of mycorrhizal roots were also increased. Foliar manganese increased and phosphorous decreased. These changes were associated with a reduction of interveinal chlorosis. ER -
