Analysis of Biomass Production in Young Loblolly Pine

We are evaluating growth data from numerous 2nd-generation progeny tests measured by the NC State University Cooperative Tree Improvement Program to characterize biofuel potential of loblolly pine. These tests were measured every year through age eight (and frequently beyond) and can be used to look at potential biomass production in young loblolly pine stands. Yearly measurements of this nature are not the norm, and this data set presents a unique opportunity to obtain real numbers for loblolly pine biofuel yields. In total, there were 25 test series with a total of 101 tests. In this analysis, only a small subset of these tests was examined. Biomass production of seven individual tests from different regions planted at a variety of spacings (from 538 to 908 trees per acre) was examined.
