Aspen and white spruce responses to organic matter removal and soil compaction in the BWBS Long-Term Soil Productivity Study

Fourth Year Responses of Aspen and White Spruce ; The BWBS Long - Term Soil Productivity Study

Short-term Effects of Forest Soil Compaction and Site Organic Matter Removal on Mineralizable Soil Nitrogen in Central British Columbia

Mineralizable nitrogen (min-N) often correlates well with plant-available nitrogen (N) in soils, and might serve as a useful indicator of whether soils are detrimentally affected by timber harvesting practices. We examined how min-N responded to soil compaction and site organic matter removal after 1 and 5 years on three sites in central British Columbia. Mineral soil min-N was found to change ...

Contrasting the Effects of Organic Matter Removal and Soil Compaction on Root Biomass of 9-year-old Red Oak, White Oak, and Shortleaf Pine in a Missouri Ozark Forest

—Nine-year old artifi cially regenerated red oak (Quercus rubra L.), white oak (Q. alba L.), and shortleaf pine (Pinus echinata Mill.) trees were excavated from plot borders of a U.S. Forest Service long-term soil productivity study in the Carr Creek State Forest near Ellington, MO, to quantify treatment eff ects on aboveand belowground tree biomass. Th e study consists of factorial combination...

Long-term tillage and residue management effect on soil compaction and nitrate leaching in a Typic Haploxerert soil

A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...

Establishment of Long-term Soil Productivity Studies on Acidic Soils in the Interior Douglas-fir Zone

A clear understanding of the impacts of forest practices on long-term soil productivity is required to maintain the productivity of forest soils while forests continue to be managed for timber production. Although current regulations governing soil conservation in British Columbia are partially based on historic and ongoing research, there are few clear and unambiguous long-term results. The ne...
