Long-Term And Seasonal Variations In Co2: Linkages To Catchment Alkalinity Generation, Stephen A. Norton, B. J. Cosby, I. J. Fernandez, J. S. Kahl, M. Robbins Church
Long-Term And Seasonal Variations In Co2: Linkages To Catchment Alkalinity Generation, Stephen A. Norton, B. J. Cosby, I. J. Fernandez, J. S. Kahl, M. Robbins Church
Earth Science Faculty Scholarship
As atmospheric emissions of S have declined in the Northern Hemisphere, there has been an expectation of increased pH and alkalinity in streams believed to have been acidified by excess S and N. Many streams and lakes have not recovered. Evidence from East Bear Brook in Maine, USA and modelling with the groundwater acid-base model MAGIC (Cosby et al. 1985a,b) indicate that seasonal and yearly variations in soil PCO2 are adequate to enhance or even reverse acid-base (alkalinity) changes anticipated from modest decreases of SO4 in surface waters. Alkalinity is generated in the soil by exchange of H+ from dissociation …
Tb169: Chemical And Physical Properties Of The Mapleton, Monson, Saddelback, And Sisk Soil Map Units, Robert V. Rourke
Tb169: Chemical And Physical Properties Of The Mapleton, Monson, Saddelback, And Sisk Soil Map Units, Robert V. Rourke
Technical Bulletins
Mapleton, Monson, Saddleback, and Sisk soil map units were each sampled at five locations. Soil descriptions and locations were documented in the field. Soil samples were removed from each horizon in a 30-cm square to a 100-cm depth or to bedrock whichever came first. Laboratory analyses of each soil horizon sampled included texture, volume of stones, organic content, bulk density, soil water retention, soil reaction, exchangeable cations, extractable acidity, and exchange acidity. Soil descriptions and tables of soil properties were constructed for each sample site. Soil data for each soil map unit was summarized by horizon using weighted means.

Tb165: Chemical And Physical Properties Of The Danforth, Elliotsville, Peacham, And Penquis Soil Map Units, R. V. Rourke
Technical Bulletins
The soils reported in this bulletin have developed in several different parent materials. The Danforth soil has developed from very deep, well drained, loose, high coarse fragment till derived from slate and fine-grained metasandstone. The Elliottsville soils have developed in moderately deep, well drained till derived from slates, metasandstones, phyllite and schists. The Penquis soils developed in moderately deep, well drained till of similar lithology as Elliottsville, but with a higher component of weathered and crushable rock fragments throughout the soil profile. Peacham soils are developed in very deep, very poorly drained, dense till derived from phyllite, schist, and granite.

The goal of this case study was to assess two components of variability associated with the land application of papermill sludge. These included (1) changes occurring within a temporary sludge stockpile, and (2) spatial variability of application to the site. Understanding the magnitude of such changes will assist in accounting for variability inherent in such land application operations.

Tb136: Methodology Development For Study Of Root Influences On Nitrogen Mineralization, M. S. Erich
Tb136: Methodology Development For Study Of Root Influences On Nitrogen Mineralization, M. S. Erich
Technical Bulletins
The current study was designed to explore a particular set of methodologies for addressing the question of whether plant root growth affects the rate of N mineralization. Specifically, the experimental design involved supplying plants with only organic N as manure and no nitrate. A highly sandy growing medium was used in an attempt to prevent overly wet conditions in the pots. In addition, instead of only comparing planted and unplanted pots, four different planting densities (0, 1, 2, 3 plants per pot ) were used as treatments.
Tb126: Vertical Trends In The Chemistry Of Forest Soil Microcosms Following Experimental Acidification, Ivan J. Fernandez
Tb126: Vertical Trends In The Chemistry Of Forest Soil Microcosms Following Experimental Acidification, Ivan J. Fernandez
Technical Bulletins
A soil microcosm experiment was conducted (a) to compare dilute H2SO4, NH4NO3 fertilizer, and prilled S as possible experimental soil-acidifying treatments and (b) to observe soil chemical response to simulated throughfall and acidifying treatments. Simulated throughfall had a significant effect on soil chemistry, resulting in increased exchangeable bases and pH in the mineral soil horizons but little effect on the O horizon. Of the acidification treatments only simulated acid rain had significant effects on soil chemistry when compared to the control and the dry treatments. This reflected the relatively slow dissolution rate of the dry treatments coupled with the short …

Tb119: Selected Relationships For Trace Metals In Maine Low Elevation Spruce-Fir Forest Floors, Ivan J. Fernandez, Miroslaw M. Czapowskyj
Technical Bulletins
Results from the analysis of trace metals in the forest floor from three study areas northern Maine commercial spruce-fir stands showed significant, positive correlations were frequently evident between ash-free concentrations of Individual pairs of trace metals. Only Pb concentrations at one location were found to vary significantly among soil drainage classes. Overall, ash-free trace metal concentrations were less than what has been found at sites receiving high loadings of atmospheric deposition in the Northeast. Few historical data are available to adequately determine if Maine forest floor trace metal concentrations are greater than the natural levels expected in commercial forests, but …

Tb98: Oxygen Diffusion Rate Relationships Under Three Soil Conditions, J. Bornstein, W. E. Hedstrom, F. R. Scott
Technical Bulletins
The objective of this study was to determine the oxygen diffusion rate (ODR)—soil moisture relationship for three sieved, root-free soils to determine if there are basic ODR-soil characteristic differences that might influence data at different soil water contents in the presence of plant roots. Advanced knowledge of ODR-soil moisture relationships would also help scientists to evaluate the effect of variation in the water table on plant growth.

Tb35: Alpine Soils On Saddleback Mountain, Maine, J. G. Bockheim, R. A. Struchtemeyer
Technical Bulletins
Alpine regions do exist in the Northeast, but are less extensive than in western United States and Alaska. Although the areal extent of alpine soils is not known in Maine, nearly 1.4 million acres of land are classified by the Soil Conservation Service as "mountainous." In Maine several mountains with subsidiary peaks greater than 4,000 ft in elevation support alpine zones, including Katahdin, Sugarloaf, Bigelow, North Brother, Saddleback, and Abraham.

Tb34: Chemical And Physical Properties Of The Charlton, Sutton, Paxton, And Woodbridge Soil Mapping Units, R. V. Rourke, C. Beek
Technical Bulletins
Charlton, Sutton, Paxton and Woodbridge soil series were each sampled at five locations. Chemical and physical properties evaluated included particle size distribution, soil reaction, moisture retention, bulk density, coarse fragment volume, exchangeable bases and acidity, saturated hydraulic conductivity, organic carbon and percolation. Properties were evaluated on a horizonal basis whenever possible. Sampling depth was to 40 inches. The samples represent a range of characteristics within each soil series. Each site is not to be considered modal for the particular soil series but was considered to within the range of characteristics of the series at the time of sampling.

Tb31: The Chemical Properties Of Seven Agricultural Soil Series And Their Relationship To Soil Fertility, Frederick E. Hutchinson
Technical Bulletins
In recognition of the importance of soil in a crop and forest production program, the Maine Agricultural Experiment Station initiated a research project in 1962 to determine the chemical properties of seven important agricultural soil series found in the state (Bangor, Caribou, Charlton, Conant, Buxton, Plaisted, Thorndike). The ultimate goal of the research was to relate the chemical properties of the soil series to the most appropriate fertility practices for their wise economic use.

Technical Bulletins
Eight soil series (Adams, Berkshire, Buxton, Colbath, Creasey, Hartland, Peru, Winooski) were sampled, each at five locations. The soil was sampled and analyzed on a horizon basis. Characteristics measured were organic carbon, moisture retention, water movement, particle size distribution, volume of coarse fragments, bulk density, soil reaction, exchangeable bases and exchangeable acidity. These data are important in the classification and interpretation of the soil resources of Maine.
