Soil nutrient management is necessary to maintain the constant productivity of nursery systems as well good quality soil. This study investigated effects organic manure and chemical fertilizer treatments on growth performance soil tissue properties. Two-year-old yellow poplar (Liriodendron tulipifera L.) seedlings were treated with an (1000 g/m2; mixture poultry manure, cattle swine sawdust), nitrogen–phosphorus–potassium (NPK) (urea, 30 fused superphosphate, 70 potassium chloride, 15 g/m2),...
Coring methods cannot reveal the distribution of roots with depth in rocky soil, and fine are typically sampled without regard to location trees. We used quantitative soil pits describe rooting patterns distance trees northern hardwood stands. sited three 0.5 m 2 each young (1927 years) older (5669 stands developed after clear-cutting. Live were divided into diameter classes delimited at 0.5, 1, 2, 5, 10, 20, 100 mm; dead not distinguished by size. Mean total live-root biomass was 2900 ±...
Faltacaria moluccana at its early plantation, is devastated by heat and water stress due to current global climate change. Production forests in Indonesia suggested use biochar enhance the durability of growth F. field. Empty fruit bunches (EFB), a gigantic abundant waste material Indonesia, pose potential as feedstock. This study aims evaluate effects EFB on for one year field setting. The experiment used two application rates (25 50 tons/ha) produced pyrolysis temperatures (400°C 600°C)....
Underground and submarine power cables are subjected to mechanical stress during installation operation, which degrades the cable insulation reduces reliability of transmission. Therefore, tests that can evaluate properties very important. The purpose this paper is introduce an improved sampling method for test sample, peeling, testing method. influence sample on property values was analyzed. tensile strength elongation XLPE (cross-linked polyethylene) PP (polypropylene) prepared by slice...
Precise forest inventory is the key to sustainable management. LiDAR technology applied tree attribute extraction widely. Therefore, this study compared DBH and height derived from Handheld Mobile Laser Scanning (HMLS), Airborne (ALS) Integrated ALS HMLS, determined applicability of integrating HMLS scanning methods estimate individual attributes Diameter at Breast Height (DBH) in pine forests South Korea. There were strong correlations for level (r > 0.95; p < 0.001)....
Precise forest inventory is the key to sustainable management. LiDAR technology widely applied tree attribute extraction. Therefore, this study compared DBH and height derived from Handheld Mobile Laser Scanning (HMLS), Airborne (ALS), Integrated ALS HMLS determined applicability of integrating scanning methods estimate individual attributes such as diameter at breast (DBH) in pine forests South Korea. There were strong correlations for level (r > 0.95; p < 0.001). ALS-HMLS achieved...
Abstract Purpose: A worldwide compassionate-use program has enabled &gt;42,000 patients with advanced non-small cell lung cancer (NSCLC) to receive gefitinib treatment. Here we report the outcome of therapy in who enrolled “Iressa” Expanded Access Program at Samsung Medical Center. Experimental Design: Patients or metastatic NSCLC had progressed after prior systemic chemotherapy and for whom no other treatment option was available were eligible as part Program. post hoc assessment...
Measuring root biomass is time consuming and prone to sampling error. We compared three different methods of measuring in six northern hardwood stands at the Bartlett Experimental Forest. found that coring, most common method sampling, yields estimates fine about 27% greater than based on roots sampled soil pits. Soil compaction contributes 10% this difference; other contributing factor cores cannot be taken through obstructions such as rocks coarse roots. Pits are only allowing...
In this study, we investigated the effects of water-deficit stress on leaf anatomical traits, physiological and stem starch content in Quercus acutissima Carruth serrata Murray by subjecting their seedlings to well-watered (WW) (WS) treatments. The water stress-induced changes trichome density, trichome-to-stomata ratio, mesophyll thickness, vein distance, loopiness, vessel diameter, transpiration (E), stomatal conductance (gs), use efficiency (WUE), were analyzed between two time points....
Urbanization and associated forest conversions have given rise to a continuum of native (forest fragments) modified (artificial grasslands perennial ecosystems) land-use types. However, little is known about how these shifts affect soil fine-root compartments that are critical functioning carbon nutrient circulation system. In this study, physicochemical properties, mass, vertical distribution patterns were investigated in four representative urban types: grassland (ZJ), agroecosystem (MP),...
Root biomass and distribution are influenced by abiotic factors, such as topography soil physicochemical properties, determining belowground productivity. Hence, we investigated the variation in root vertical based on topography, tree influence index, their relationships, across depths (0–10 cm, 10–20 20–30 cm) topographical gradients a warm-temperate forest Mt. Duryun, Republic of Korea. Two contrasting research sites were established: lower slope oriented at ≤3° an upper with 30°. Each...
Knowledge about carbon and nutrient fluxes by litterfall is important for understanding cycling in geologically unique ecosystems. However, the determination of forest production patterns difficult due to many biophysical factors influencing process. In this study, we (1) quantified warm-temperate evergreen stands Jeju Gotjawal (2) compared these values those a typical cool-temperate deciduous stand types climate differences. Litterfall from broadleaved forests at Cheongsu (CS) Seonheul...
Forest canopies are often stratified by species; little is known about the depth distribution of tree roots in mixed stands because they not readily identified species. We used diagnostic characteristics wood anatomy and gross morphology to distinguish species applied these methods test for differences rooting sugar maple ( Acer saccharum Marsh.), American beech Fagus grandifolia Ehrh.), yellow birch Betula alleghaniensis Britt.) two northern hardwood forests. also distinguished hobblebush...
