  • Observations and snow model simulations of winter energy balance terms within and between different coniferous forests in southern boreal Finland

    Variation of canopy properties between different forest types is seldom taken into account in hydrological and climate models, and consideration of variation inside a forest is normally omitted. In this work, three data sets on near surface energy balance terms (incoming shortwave and longwave radiation; air and snow–soil interface temperatures) were collected in the southern boreal coniferous ...

  • Time for Trees to Pack Their Trunks?

    As climate changes, forest ecosystems will need to shift to more suitable sites. Should humans lend a helping hand? During the last two springs, contract planters for The Nature Conservancy have spread out through the pine, spruce and aspen forest of northeastern Minnesota. Wielding steel hoedads, they have planted almost 110,000 tree seedlings on public ...

  • Lumber company expedites shipping procedures

    Pukall Lumber Company, located in Arbor Vitae, Wisconsin, is a family-owned and operated wood products manufacturer. The business is two-pronged; the sawmill was founded in 1937 and later a retail building supply was added to sell lumber and other building materials to area builders. Pukall handles red and white pine logs primarily, sawing them into accurate dimension lumber for the construction ...

  • The impact of beetle-induced conifer death on stand-scale canopy snow interception

    Bark beetles have killed more than 100,000 km2 of pine forest in western North America, causing trees to lose the majority of their canopy material and potentially leading to enhanced subcanopy snow accumulation. Over a 45-day period, we tested this hypothesis by measuring daily snow accumulation in three living and two dead lodgepole pine stands and in three adjacent clearings. The largest ...

  • Air‐plant exchange of brominated flame retardants at a rural site: Influencing factor, interspecies difference, and forest scavenging

    Brominated flame retardants (BFRs) in eucalyptus leaves and pine needles from a rural site in southern China were measured to investigate the air‐plant exchange. The mean concentrations of BFRs were higher in pine needles (79.8 ng/g dry weight) than in eucalyptus leaves (74.5 ng/g), whereas an inverse result were found for the leaf surface particles (LSPs), with mean concentrations of 3490 and ...

  • The fate of lead at abandoned and active shooting ranges in a boreal pine forest

    Changes in leaching, availability, bioaccumulation, and vertical distribution of lead (Pb) in soil 20 years after the cessation of shooting activity were studied by comparing three pine forest sites in southern Finland: an active shooting range, an abandoned shooting range, and a noncontaminated control site. At both shooting ranges, shooting activity had lasted for 20 years, but it had taken ...

  • Aspect and soil textural controls on snowmelt runoff on forested Boreal Plain hillslopes

    Plot studies were conducted on a jack pine forest with sandy soil and aspen forests with sandy and loam soils to examine the controls of slope aspect, soil texture and fall soil moisture content on near-surface snowmelt runoff and infiltration. It was hypothesized that near-surface runoff would be greater from north-facing slopes on loam soils with increased fall soil moisture content. Fall soil ...

  • Nitrogen and sulphur transformations in composts containing chicken feathers

    Chicken feathers composted with pine bark and rye straw are subject to intensive mineralisation and biotransformation with efflux of water-soluble components: N-NH4, N-NO3 and S-SO4. The content of N-NH4, N-NO3 and S-SO4 in water extracts of the studied composts was positively correlated with the time of composting. The release of those components reached a maximum after 15 weeks of composting ...

  • Effect of maturation of Grease trap compost on plant growth

    Although it is known that immature composts can depress plant growth, few studies have quantified this effect in real-world scenarios with field-grown crops. Glasshouse and field trials were used to investigate the effect of maturation of grease trap compost (GTC) on plant growth. Grease trap waste was composted for 7-14 d in an in-vessel reactor with shredded green waste, sawdust and chicken ...

  • Effect of loblolly pine root pruning on alley cropped herbage production and tree growth

    Tillage to disrupt (prune) tree roots is an intensive practice which could improve herbage productivity at the crop–tree interface by reducing competition for water. We compared tillage effects on 9- to 11-yr-old loblolly pine (Pinus taeda L.) growth and herbage yields of annual ryegrass (Lolium multiflorum Lam.) and pearl millet [Pennisetum glaucum (L.) R. Br.] on a fragipan soil in Arkansas. ...

  • Organic acids and Aldehydes in throughfall and dew in a Japanese pine forest

    We analyzed low molecular weight organic acids and aldehydes in throughfall under pine forest, and organic acids in dew on chemically inert surfaces and pine needle surfaces at urban- and mountain-facing sites of pine forest in western Japan. Low molecular weight organic acids and aldehydes accounted for less than 5% of the dissolved organic carbon in throughfall at both sites. Formaldehyde at ...

  • Seven decades of Calcium depletion in organic horizons of Adirondack forest soils

    We used repeated sampling of the forest floor to determine if there was a net loss of Ca from organic horizons of Adirondack forest soils between 1930 and 2004. In 1984, we established 48 permanent plots in spruce–fir, northern hardwood, and pine stands located in areas sampled by Carl C. Heimburger in the early 1930s. Following Heimburger's protocols and analytical methods, we measured pH and ...
