Yields of herbage, animal gains, carrying capacity and TDN production were determined for three pasture swards grown on a Grey Wooded soil (Albright-Hythe series) in the Peace River region of northern Alberta over the period 1953 to 1956 inclusive. Sheep were used as grazing units. Fertilizer treatments of nil, ammonium phosphate (11-48-0) at 300 pounds per acre and ammonium nitrate (33-0-0) at 100 pounds per acre were applied annually to pastures of creeping red fescue, creeping red fescue-alfalfa and bromegrass-alfalfa.Productivity obtained with unfertilized grass-legume mixtures was almost double that for unfertilized grass grown alone. Increased production attributable to alfalfa was also obtained, although to a lesser degree, where fertilizers were used. Pastures of creeping red fescue seeded alone and with alfalfa responded markedly to applications of nitrogen while responses to phosphorus were negligible. Conversely, bromegrass-alfalfa pastures responded strongly to applications of phosphorus and only slightly to nitrogen.

Limited Change

Although many of the surviving lineages of sea stars appeared during an early Mesozoic radiation of the class and have undergone limited change since then, they have left a very poor fossil record, particularly in the Mesozoic of North America (Blake, 1981). This record from the Late Cretaceous of Alberta is made more significant by the fact that it is apparently only the second occurrence of a member of the family Astropectinidae in the Cretaceous of North America; Lophidiaster silentiensis was described by McLearn (1944) from the Lower Cretaceous (Albian) Hasler Formation, from a now-submerged locality on the Peace River in northern Alberta. All previously recorded fossil sea stars from the North American Cretaceous are representatives of the family Goniasteridae.

Delayed neutron activation analyses of 182 core samples from the basement of the western Canada sedimentary basin give mean values of 4.13 ppm U and 21.1 ppm Th. These values are almost twice the published values for the Shield as a whole. Replicate analyses of a composite sample of all cores indicates an analytical precision of ±1% for uranium and ±7% for thorium.Histograms of number of samples vs. U and Th values indicate a negatively skewed frequency distribution. Analysis of composite samples prepared from a large number of hand specimens may tend to conceal this skewed nature. Mean abundance values will also be influenced by the form of the U and Th frequency distributions.Trend surface analysis, with smoothing to reduce the effect of high or low single sample values, indicates two 'highs' common to both U and Th. The helium-producing area around Swift Current, Saskatchewan is associated with a high U–Th plutonic complex. A linear belt trending northeast from Edmonton appears to be a Hudsonian metamorphic belt in which U and Th have been concentrated. Several local concentrations of U or Th are found in the Peace River Arch of northern Alberta.

Early Cretaceous paleogeography and biostratigraphy of western Canada are reviewed in light of a reassessment of foraminiferal and microfloral data from unpublished university theses on the early Albian Loon River shales of the lower Peace River area of northern Alberta (Norris 1951; Trollope 1951). The Loon River Formation, once considered to be an obsolete term, comprises numerous “zones” of foraminifera, radiolarian, and algal cysts, in ascending order Rectobolivina sp., lower Radiolarian zone, lower Leiosphaeridia zone, Haplophragmoides yukonensis, upper Radiolarian zone, upper Leiosphaeridia zone, Trochammina mcmurrayensis, Valvulineria loetterlei, Haplophragmoides topagorukensis, Marginulinopsis collinsi, and Haplophragmoides gigas minor. The upper part of the Loon River Formation, from the upper Radiolarian zone onwards, correlates with the McMurray, Wabiskaw, and Clearwater formations of the Fort McMurray area of northeastern Alberta. Molluscan data from various localities in western Canada indicates that the entire Loon River succession occurred within the early Albian. The presence of Inoceramus dowlingi and Cleoniceras sp. with the Marginulinopsis collinsi microfauna permits correlation of the type Clearwater Formation and type McMurray Formation with the Moosebar Formation of northeastern Bristish Columbia. An anomalous thick sequence of Leiosphaeridia (algal cysts) beds, bounded above and below by radiolarian-bearing strata, occurs in the mid part of the Loon River shales outcropping ~40 km along the lower Peace River. The Trochammina mcmurrayensis microfauna occurs 2–3 m below Inoceramus dowlingi and 30 m above Cleoniceras sp., and above the upper Leiosphaeridia zone. The radiolarian and Leiosphaeridia beds are considered to be the offshore neritic homotaxial equivalent of deltaic strata in the upper part of the McMurray Formation. The mid and lower Loon River shales are potential oil sources for the tar of the McMurray Formation, and this is supported by recent radiometric dating of the tar by Rhenium–Osmium isotopic analysis.

The feasibility of dormant seeding canola in the fall in the Peace River region of northern Alberta was assessed. Results indicated that there is a significant risk of crop failure with fall seeding, mainly due to poor spring seedling emergence. Where a fall-seeded canola crop established, flowering and seed maturity occurred earlier even though plant densities were lower with fall compared with spring seeding, and seeding date had little or no effect on canola seed yield or quality. Tillage (minimum or zero) or nitrogen rate, source or placement had no consistent effects on canola productivity. Canola growers in the Peace River region are unlikely to achieve higher yield and quality by seeding canola in the fall. Key words: Dormant seeding, fertilizer rate, source and placement, minimum and zero tillage, polymer coated canola seed

Bt Horizon

In the Peace River area of northern Alberta difficulty has been encountered in adopting the new Canadian classification scheme to a series of soils which occur under similar environmental conditions but still reflect varying degrees of profile development. The variation in profile development ranges from what appears to be almost Orthic Regosol to Orthic Grey Wooded. These soils are mapped as the Judah and Kathleen series by the Alberta Soil Survey. The analyses showed that the soils, under study, had a definite Bt horizon. The chemistry of the solum and clay mineral content were found to be similar to Grey Wooded soils in Alberta. Profile studies suggest erosion from the surface of these soils had occurred. The soils were classified as being both Chernozemic and Podzolic and belonging to three subgroups, namely Orthic Dark Grey, Dark Grey Wooded, and Orthic Grey Wooded.

CHARACTERISTICS OF FERA ELUVIATED GLEYSOLS DEVELOPED FROM ACID SHALES IN NORTHWESTERN ALBERTA

Fera Eluviated Gleysols developed on highly acidic parent materials are commonly encountered on flat-lying landscapes in the Peace River region of northern Alberta. Characteristics of these soils suggest, a genetic origin, with processes similar to those encountered in Luvisols and Gleysols. Alternation between the two processes has resulted in the formation of a B horizon enriched with clays, principally from the overlying eluviated horizon, and hydrated iron oxides introduced, in part, through groundwater discharge. Goethite, maghemite, and lepidocrocite were identified in horizons containing high concentrations of secondary iron oxides. The unusually high acidity common to these soils is attributed to biogeochemical oxidation of pyrite in the oxidizing zone of the surface geological deposit, and not to pedogenic processes.
