The national soil-mapping project initiated and led by Kreybig was unique being a national, large-scale survey based on field and laboratory soil analysis and in the meantime serving practical purposes. By its completion, in the early 1950s, Hungary was the first country in the world having such detailed soil information for the whole country. The Kreybig maps are still timely, because the temporal changes in the mapped soil characteristics are not significant. The GIS adaptation of information originating from this survey is under construction, but there is more utilizable information originating from this survey, than it was published in the map series and in reports, and what is provided by simply archiving them digitally. Compilation of the Digital Kreybig Soil Information System as a national spatial soil information system involves both its integration within appropriate spatial data infrastructure and updating with efficient field correlation, which make an inherent refinement and upgrading of the system possible. The field-based updating of DKSIS using field GIS technology by the implication of recent data collected at revisited sites makes the comparison of archived and newly surveyed soil state possible. This, in one hand, should be recorded in the database by updating it. On the other hand, trends can be identified in soil characteristics, thus processes can be realized and/or forecasted. Based on the upgraded database we produce soil maps (i) displaying recent state of soils (ii) with increased accuracy and (iii) according to the soil-mapping concept elaborated by Kreybig et al.

A field experiment was conducted under rainfed conditions, on a shallow soil (Inceptisol) underlain with weathered basalt and on a deep soil (Vertisol) to evaluate three cotton cultivars [AKH 4 ( Gossypium arboreum ), LRK 516 ( G. hirsutum ) and NHH 44 (intra- hirsutum hybrid)] under four levels of N (0, 40, 80 and 120 kg ha −1 ) and to analyse the variations in productivity using the nitrogen use efficiency (NUE) parameter. The yield of AKH4 and NHH 44 was 101 and 89% higher than that of LRK 516. The yield and the response to N were higher on the Inceptisol. The enhanced yield and NUE of AKH 4 and NHH 44 were attributed to the improved efficiency of N uptake utilization. NUE declined from 21.6 at 40 kg ha −1 to 7.7 at 120 kg N ha −1 . The N uptake efficiency and N utilization efficiency were independent of each other, but complemented each other in improving NUE. The implications of variations in NUE, N uptake efficiency and N utilization efficiency and their components, N biomass production efficiency and HI, in cotton breeding and agronomy are also discussed.

Abstract
The calibration of a tube excited Energy-Dispersive X-Ray Fluorescence spectrometer for routine geochemical analyses of Ca, Ti, V, Cr, Mn, Fe, Cu, Zn, Rb, Sr and Pb in Jamaican soils and sediments is described. Simple linear and parabolic regression models using scattered radiation and an element as internal standards were applied. The analysis of over 200 samples from a regional soil survey has been used to contribute to a database on the geochemistry of Jamaican soils and sediments. An application example of the Zn distribution map in Jamaican soils is presented.

Abstract
Soil surveys of radon conducted in the Coastal Plain of New Jersey, Alabama and Texas indicate that soil composition and grain size exert the strongest control on the concentration of radon measured. Soil-gas radon was measured in-situ using two techniques; one developed by G. Michael REIMER of the U. S. Geological Survey; the other developed by Rogers and Associates Engineering Corp. for use by the Environmental Protection Agency. The Reimer technique aquires a small-volume, grab sample of soil gas, whereas the Rogers and Associatess technique acquires a large-volume, flow-through sample of soil gas. The two techniques yield similar radon concentrations in well-sorted sands, but do not correlate as well for poorly sorted soils and clays.
