Autor: Emerson D. Nafziger, Lisa C. Gonzini, Matthew W. Clover, Kristin D. Greer, Jeffery J. Warren, Cameron M. Pittelkow, R. G. Hoeft
Publikováno v: Journal of environmental quality. 46(5)
Nitrogen (N) management strategies that maintain high crop productivity with reduced water quality impacts are needed for tile-drained landscapes of the US Midwest. The objectives of this study were to determine the effect of N application rate, timi

Apparent Nitrogen Recovery from Fall‐Applied Ammoniated Phosphates and Ammonium Sulfate Fertilizers
Autor: Emerson D. Nafziger, Fabián G. Fernández, R. G. Hoeft, María B. Villamil, Kristin D. Greer, Jeffrey A. Vetsch, Gyles W. Randall
Publikováno v: Agronomy Journal. 102:1674-1681
Phosphorus fertilizer is frequently fall-applied for corn (Zea mays L.). Diammonium-(DAP) or monoammonium-phosphates (MAP) are the preferred P fertilizers and the N in MAP and DAP is assumed to be available for corn. Our objective was to evaluate the

Nitrogen fertilization and cropping system impacts on soil properties and their relationship to crop yield in the central Corn Belt, USA
Autor: Eric A. Adee, R. G. Hoeft, Emerson D. Nafziger, Rattan Lal, Sindhu Jagadamma
Publikováno v: Soil and Tillage Research. 98:120-129
Evaluating the effects of management practices on soil physical and chemical properties would be valuable to explain field-level variability in crop production. A 23-year-old experiment on a Muscatune soil (fine-silty, mixed, superactive, mesic, Aqui

Nitrogen fertilization and cropping systems effects on soil organic carbon and total nitrogen pools under chisel-plow tillage in Illinois
Autor: Eric A. Adee, R. G. Hoeft, Rattan Lal, Sindhu Jagadamma, Emerson D. Nafziger
Publikováno v: Soil and Tillage Research. 95:348-356
Agricultural soils can be a major sink for atmospheric carbon (C) with adoption of recommended management practices (RMPs). Our objectives were to evaluate the effects of nitrogen (N) fertilization and cropping systems on soil organic carbon (SOC) an

Chlorophyll Meter Readings Can Predict Nitrogen Need and Yield Response of Corn in the North‐Central USA
Autor: Sylvie M. Brouder, Peter C. Scharf, R. G. Hoeft
Publikováno v: Agronomy Journal. 98:655-665
Nitrogen fertilizer is a fundamental input for production of corn (Zea mays L.) that can move to ground and surface waters when over-applied. Previous research has shown that chlorophyll meter (CM) readings can indicate N stress in corn, but has not

Spatial Variability of the Illinois Soil Nitrogen Test: Implications for Soil Sampling
Autor: Germán A. Bollero, Donald G. Bullock, Matías L. Ruffo, R. G. Hoeft
Publikováno v: Agronomy Journal. 97:1485-1492
The Illinois Soil Nitrogen Test (ISNT) is a recently developed test that has shown promise for corn (Zen mays L.) N fertilization. However, among-field and within-field spatial variability of this test is unknown and sampling recommendations have not

Fate of Nitrogen‐15 in a Long‐Term Nitrogen Rate Study: II. Nitrogen Uptake Efficiency
Autor: Richard L Mulvaney, William B. Stevens, R. G. Hoeft
Publikováno v: Agronomy Journal. 97:1046-1053
Increased fertilizer N uptake efficiency (FNUE) leads to more economical corn (Zea mays L.) production and lower environmental impact. Excessive N application reduces FNUE and may affect subsequent crop response through its influence on NO 3 -N carry

Fate of Nitrogen‐15 in a Long‐Term Nitrogen Rate Study: I. Interactions with Soil Nitrogen
Autor: R. G. Hoeft, William B. Stevens, Richard L Mulvaney
Publikováno v: Agronomy Journal. 97:1037-1045
A better understanding of how N management practices affect transformations and movement of fertilizer N may lead to more efficient N management. The objectives of this work were to determine how long-term N fertilizer history in a continuous corn (Z
