Nitrogen Testing The Illinois soil N test (ISNT)
This test, developed within the Department of Natural Resources and Environmental Sciences to estimate potentially mineralizable organic nitrogen, will bring about a shift from yield- to soil-based management of N fertilization. The result will be higher N use efficiency, with major economic and environmental benefits.
New study on N fertilization suggests this does not build soil organic matter
URBANA - The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began.
Digital Soil Map of the World and Derived Soil Properties. Rev. 1. (CD Rom)
This CD-ROM contains the Digital Soil Map of the World in various formats, verctor as well as raster, supported by most GIS software. The base material is the FAO/UNESCO Soil Map of the World at an original scale of 1:5 million. Programs and data files give tabular country information on soil characteristics and derived soil properties from the map are included, such as pH, organic carbon content and soil moisture storage capability. In addition programs and data files are included that display derived soil properties. The revision included the adding of a number of user-friendly ArcView files allowing the display of dominant soils by continent and the inclusion of the update of the image of the WRB World Soil Resources Map. [System requirements: Pentium PC with Windows 9x/NT/2000/, at least 64 Mb RAM and 15" or larger colour monitor with a resolution of 1024 x 768 pixels and a colour palette of 65 536 colours. - For ARC/INFO Export vector maps: ARC/INFO software on Windows PC or other platforms that support ARC/INFO such as VAX/VMS and UNIX; - For maps in ARC/INFO native vector format: ArcView 3.1 or later; - For ERDAS raster maps in ERDAS version 7.5 format: ERDAS 7.5 or later or any other software that can import ERDAS 7.5 GIS files. - For raster maps in IDRISI IMG format:IDRISI software on PC and image-processing software that can read flat raster files]
Project to assess nutrients in soil profiles in Illinois
Introduction In the late 1960s, a University of Illinois project coordinated by Sam Aldrich, Ted Peck, and Bill Walker collected soil and plant samples from fields throughout Illinois to establish a baseline of soil profile nutrient levels and crop uptake for corn and soybeans. This report summarizes results from samples collected in 1967, 1968, and 1969, from about 20 corn and soybean fields in each of 75 Illinois counties. A similar earlier project outlined in University of Illinois Agricultural Experiment Station Bulletin No. 123 , reported on a similar statewide survey conducted about 100 years ago. These surveys provide important benchmarks of the nutrient status of Illinois soils and help track the impact of nutrient removals in crop production and additions in fertilizer and livestock manure. FREC Project #313 was designed to provide a checkpoint to determine whether there has been significant change in soil nutrient profiles in the past 4 decades since the last survey was completed.
