Soil samples were collected over 14 years from a sandy loam forest soil in northern Minnesota. During the study earthworm numbers increased from zero to 592 m−2, the forest floor weight and thickness decreased by about 85%, and the E horizon was co

Total ecosystem carbon in the soil and vegetation was measured for a range of aspen (Populustremuloides Michx.) ecosystems, including a chronosequence on the same soil ranging in age from 0 to 80 years. Soil carbon stayed relatively constant througho

Nutrient analysis was done for adjacent, 40-year-old stands of pure quaking aspen (Populus tremuloides Michx.), white spruce (Picea glauca Moench Voss), red pine (Pinus resinosa Ait.) and jack pine (Pinus banksiana Lamb.) on two soils in Minnesota to

The biomass of 76 jack pine (Pinusbanksiana Lamb.) trees (29 stands) and 72 red pine (P. resinosa Ait.) trees (28 stands) from throughout the northern Lake States was determined. All trees were from even-aged, unthinned plantations ranging from 20–

Red pine produced significantly more volume than the other species on all five sites in the Lake States. By age 40 to 50 white spruce was second to red pine and beyond this age it is expected that these two species will increase their lead over the o
