Item Research Summary on a Long-Term Planting Depth Study(2007-09-05) Hanson, DaveThe focus of this study is to determine how quickly stem encircling (SERs) or stem girdling roots (SGRs) occur, and to determine what (if any) relationships exist between planting depth and suckering, SERs, SGRs, or growth rates. While there are some interesting trends, few solid conclusions can be drawn from the data collected thus far.Item Research Summary on Pot-In-Pot Production and Planting Depth(2006-04-03) Hanson, DaveThis focus of this research study investigates the nursery practice of placing trees deeply in containers to prevent wind-throw and excessive lean. After four months of observation, tree lean, caliper and root volume were analyzed, and results showed no association between planting depth and occurrence of windthrow. A lower proportion of trees required staking when planted at greater depth of soil. Species-specific associations between planting depth and root volume and caliper were observed, and these findings can help inform standard nursery practices.
