The article discusses the analysis of Gottlob Frege and David Hilbert on formalist doctrine which is consistent to an arbitrary set of mathematical sentences in sufficient condition for truth and for the existence of the described concepts. Frege and Hilbert used the formalist approach and the axiomatic method with later work in foundations with speculation. In addition, the concept was based on the neglected revision of Hilbert idea on the existence of mathematical sentences.

Typified soils were developed for the water balance simulation of the Stöbber creek catchment. The occuring soil types within the catchment were listed and most frequently soil profiles created according to substrate, horizon stratification and thickness. Soil physical properties were estimated for the horizons. Both measured and estimated soil data based on pedotransfer procedures were used. The soil data were tested at reference soil profiles by comparing of soil hydrological field measurements with simulation results of deep seepage. As the results show, using measured soil data it is not necessary to produce sufficiently accurate simulation results of the vertical one dimensional water transport. Estimating soil hydrological data based on average substrate/horizon properties as well as using pedotransfer functions produced satisfactorily results. [ABSTRACT FROM AUTHOR]

Conduct of wind tunnel tests for corn and sugar beets to investigate their protection against wind erosion; Investigation of soil loss in dependence of plant growth and their orientation to wind direction; Reason behind estimation of drag partition between plants and soil surface.
