The comminution of fuelwood for efficient transportation and handling exposes the material to various biological chemical decomposition processes. stockpiling fuel chips can result in significant dry matter losses (DML) consequent release CO2 into atmosphere. processes could be controlled by managing chip moisture content (MC). MC control utilizing self-heating stockpiled stemwood together with...
This study’s aim was to calculate the weathering rates of Ca and Mg for five boreal forest soils in southern Finland on granitic gabbro containing bedrock. The effect mineralogy total concentrations soil evaluated. also estimate mechanical disturbance related ploughing area. SiO2, CaO, MgO, Zr were determined by XRF, based changes concentrations. Ca+Mg varied 5–38 mmolc m–2 year–1 E+B/BC horizo...
Growth patterns of vertical stems in nine ponderosa pines from a stand in the southern Sierra Nevada were analyzed for recent changes due to stand dominance position, age, climate, and ozone exposure. Large positive correlations were found between increments in volume growth and basal area at d.b.h. The results indicated that patterns of wood distribution along the bole were associated with age...
Abstract Tree seedlings are produced in tree nurseries. However, nursery-grown often exhibit poor performance after outplanting due to the lack of adaptation harsh natural conditions. These do not necessarily possess well-developed ectomycorrhizal symbionts, which help obtain nutrients and increase resilience exchange for seedling photoassimilated carbon. To improve quality conditions, we sowed...
