Practical Field Method of Site Evaluation for Commercially Important Southern Hardwoods

摘要

The paper provides a method of site evaluation for cottonwood, green ash, hackberry, sugarberry, pecan, sweetgum, sycamore, yellow-poplar, and cherrybark, Nuttall, Shumard, swamp chestnut, water and willow oaks. The method incorporates an evaluation of the physical, moisture, nutrient, and aeration properties of a soil into a site quality rating. Field tests have demonstrated the accuracy of the technique. The site evaluation technique also provides a basis for possible soil improvement treatments for the 14 hardwood species and estimates of potential productivity for cottonwood, sweetgum, and sycamore plantations.
