Spatial Variability of Corn Response to Nitrogen Fertilizer: Implications for Variable Rate Fertilization
… variability of the Illinois Soil Nitrogen Test (ISNT). On-farm experiments were conducted in sixteen fields in Illinois using production agriculture equipment. Site-specific production functions for corn nitrogen fertilization were developed based on terrain attributes, the ISNT and nitrogen …

Continuous No-till Management: Implications for Soil Quality, Carbon Sequestration, and Nitrogen Conservation
… and iii) evaluate the Illinois soil N test (ISNT) for its value to predict fertilizer N needs of corn in Virginia. Objectives i and ii were achieved by collecting soil samples from 63 production fields in the Virginia Coastal Plain that were managed using continuous no-till from 0 to 14 yrs. …

An Approach to Using Labile Soil Nitrogen Measurements for Calibration of the Dssat-Century Agroecosystem Model for Site-Specific Nitrogen Fertilizer Management in Illinois, Unites States
… modeled variables and soil N fractions as the ISNT. If such relationships can be identified, it should be possible to use site-specific measurements of soil N fractions to better predict crop responses to fertilizer applications. Although it was possible to obtain reasonably good fits to N …

Autoradiographische Untersuchungen zu nukleären DNA-Strangbrüchen in unterschiedlichen Zellarten im Gehirn der Maus nach einer achtwöchigen 50-Hz-Magnetfeldexposition
… this study was to use in-situ nick translation (ISNT) to investigate the relative number of unrepaired nuclear (n) DNA nicks in different cell types in the brain of the 9-month-old mouse after a 2-month exposure to a 50 Hz magnetic field with 0 mT (control), 0.1 mT or 1 mT. 5 minutes after the …

Induzierter Zelltod von transdifferenzierten hepatischen Sternzellen (Myofibroblasten) auf der Basis des Thymidinkinase-Ganciclovir-Systems
… to the supposition that h-TIMP-1-promoter isnt active in quiescent HSC. The induced cell death was identified as apoptosis; necrosis could be excluded. For further animal experiments with rats a detailled plan was established. The effect of liver fibrosis as a consequence of bile duct …

Effect of winter cover cropping practices on maize yield and nutrient cycling
… soil with a higher Illinois Soil Nitrogen Test (ISNT). Nitrogen fertilizer rates and timing had a significant impact on final yields with the highest yield being 16.9 Mg ha-1 (271 bu ac-1) at a nitrogen fertilizer rate of 177 kg ha-1 (158 lb ac-1) for the conventional tillage treatment and 16.4 …

Bestimmung von 3-Nitrotyrosin im Liquor als Hinweis für nitrosativen Stress
… 3-NT could be detected. Furthermore this method isnt that expensive compared to other methods such as mass-spectroscopy, which is an important factor in routine 3-NT-investigation. At first, several experiments were made to show that our used machine worked exact and linear, and to show the …
