Abstract. The drumlin section recently discovered near Hörmating in the Upper Bavarian area of the Würm Glaciation and evaluated with regard to stratigraphy, paleoclimatology, and chronology by E. Ebers (in this annual) can closely be correlated with the typical loess section of eastern Lower Austria, particularly with its Fellabrunn (Göttweig) fossil soil complex as described and interpreted by F. Brandtner. The Göttweig loamificaton developed during the Hörmating Interstadial from c. 47000 (or 48000) until the close marked by a thin peat layer 45300±1000 C-14 years old. As some findings are suggestive of at least one cold oscillation, the term „Göttweig Interstadial Complex" appears to be correcter. This period interrupted the glacial climate of the Würm Glaciation from c. 47000 (or 48000) until c. 30000 B. P. The northern alpine Piedmont Glaciation was initiated by an advance-gravel later on weathered on the surface probably during the Paudorf Interstadial and advanced entirely (or almost entirely) during the Main Würm Stage from the (Swiss) Aare to the Salzach rivers, after several Lower Würm gravel masses had poured out of the Alps valleys during the Early Würm Stage. This Lower Würm gravel was capped by a weathered (decalcified) stratum 2-3 metres in thickness and can contain up to three interstadial Schieferkohle (Pleistocene lignite) beds intercalated, the lowermost overlying a Schieferkohle stratum deposited during the Riss-Würm Interglacial at some sites.

Based on the introduction of the characteristics of the supporting project of a large building foundation pit, the paper analyzed the main reasons for side wall collapse and pile fracture, including leakage water in the backfill soil, complex geological environment and unreasonable soil pressure value, low safety factor and improper design parameters, and then respectively proposed three kinds of treatment schemes for side wall sliding and pile breaking, landslides and other dangers. Finally, tracking observation showed that the satisfactory effect can strongly verify the suitability and validity of the main control parameters for the deformation of deep foundation pit, which may provide reference for the design and construction of similar projects.

Vegetation and soils were sampled in adjacent 40-year-old stands of red pine (Pinusresinosa Ait.), jack pine (Pinusbanksiana Lamb.), white spruce (Piceaglauca (Moench.) Voss), and aspen (Populustremuloides Michx., P. grandidentata Michx.) on a very fine sandy loam soil in north-central Minnesota. Total tree biomass was greatest for red pine followed by aspen, spruce, and jack pine. Nutrient weights (N, P, K, Ca, Mg) in the trees were greatest in aspen followed generally by spruce, red pine, and jack pine. Particularly large proportions of biomass and nutrients were found in aspen bark and spruce foliage and branches. Understory biomass contributed less than 1.2% of the total organic matter in the vegetation–soil complex but contributed up to 5.0% of the nutrients. Exchangeable Ca in the surface soil was much lower under aspen and spruce than under the pines. No significant soil differences between species were detected below 36 cm. Harvesting the entire aboveground portion of the tree would remove up to three times more nutrients from the site than would harvesting only the bole.

A field study was conducted in the period 2004–2007 at the Czesławice Experimental Farm, belonging to the University of Life Sciences in Lublin, on loess-derived grey brown podzolic soil (good wheat soil complex). This study determined the effect of two levels of nitrogen fertilization on yield and the basic quality traits of grain of the winter wheat cultivar ‘Muza’. The study results show the dependence of the grain quality characters mainly on variable weather conditions throughout the study period and to a lesser extent on the level of nitrogen fertilization. Good technological parameters were obtained in the seasons with low rainfall and high air temperature. The study also demonstrated that the higher rate of nitrogen tended to have a positive effect on total protein and wet gluten content, falling number, sedimentation value, and grain test weight. In spite of the lack of significant differences, the quality of gluten was found to decrease with the increasing rate of nitrogen.
