TY - JOUR T1 - Effects Of Turf Competition and Fertilizer Application On Trunk Diameter and Nutrient Composition Of Honeylocust JF - Arboriculture & Urban Forestry (AUF) SP - 156 LP - 159 DO - 10.48044/jauf.1984.030 VL - 10 IS - 5 AU - Houchang Khatamian AU - John C.

A 60 cm turf clearing around the tree trunk was maintained using glyphosate. Tree trunk diameter was the same for the first growing season regardless of the treatment. In the second growing season, Nitroform at 227 g/tree resulted in greater trunk diameter than the control plants. ProGrow at 278 g/tree gave growth similar to the Nitroform. Doubling the fertilizer rate did not increase tree growth. Fertilized plants had a greater foliar N and chlorophyll content and appeared greener than the control plants. ER -
