dc.description.abstractForests ecosystems are governed by complex and dynamic nutrient cycles where soil is a major provider of nutrients essential for plant growth. Disturbances occurring in forested ecosystems (timber harvest, fire, and disease breakouts) lead to removal of living biomass which may impact nutrient cycling and can cause changes in soil solution chemistry, nutrient flux, and alter soil moisture and temperature. Missouri Ozark Highland soils are highly weathered and, to maintain long-term sustainability and productivity of forests supported by these soils, understanding harvest operations effect on nutrient loss is of utmost importance. Therefore, the primary objective of this study was to enhance understanding of nutrient dynamics and pools in forested soils of the Missouri Ozark Highlands. The study was divided into two specific research objectives: (1) quantify the influence of clearcutting (CC) and single tree selection forest (STS) regeneration on soil solution chemistry and nutrient flux in low and medium nutrient status soils at Missouri Ozark Forest Ecosystem Project (MOFEP); and (2) identify the importance of geomorphic and soil properties on total and available P concentrations in Ozark Highland soils. To address concerns regarding the depletion of soil nutrients in association with timber harvest in the Missouri Ozark Highlands, soil solution and nutrient flux in low and medium nutrient status soils was monitored in clearcut, single tree selection, and no-harvest management sites (NHM) at MOFEP. Pre-harvest and post-harvest solution samples were collected with throughfall and zero-tension soil solution (ZTS) samplers (15 and 40 cm depths), and samples were analyzed for pH and electrical conductivity (EC), anions (F- , Br- , Cl- , NO2 - , NO3 - , SO4 2- , PO4 3- ), cations (K+ , Na+ , NH4 + , Ca2+, Mg2+, and total aluminum), dissolved organic carbon (DOC), and total nitrogen (TN). Ion exchange resin (IER) samplers (15 and 40 cm soil depths) were used to capture cumulative flux. Pre-harvest and one year post heng
