Evaluating P And K Fertilizer Prescriptions From Site-Specific Technologies, John H. Grove, E. M. Pena-Yewtukhiw

Soil Science News and Views

Developing a field's fertilizer prescription as a part of a site-specific nutrient management plan can be one of the more costly tasks undertaken. Those costs are traditionally associated with gathering of a number of plant and/or soil samples, their testing, as well as acquiring and applying amendments. Soil sample analysis is particularly important for traditional phosphorus (P), potassium (K) and soil acidity (pH) management. Soil sampling requires skill and time, time that may be in short supply when crop harvest is to be soon followed by establishment of a succeeding crop. Soil test results are not always timely, further delaying …

Groundwater Quality In Kentucky: Iron, R. Stephen Fisher, Bart Davidson

Information Circular--KGS

Iron is one of the most abundant elements in rocks and soils, and one of the most common problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves iron and carries it to wells and springs. In deep groundwater systems that lack oxygen, iron occurs as dissolved ferrous ion and the water is clear. Under oxidizing conditions such as in shallow groundwater systems or where the water is exposed to air at a tap or faucet, however, iron converts to a ferric form when it combines with oxygen to form reddish-brown rust particles. In addition to natural sources, elevated …

Species Richness And Soil Properties In Pinus Ponderosa Forests: A Structural Equation Modeling Analysis, Daniel C. Laughlin, Scott R. Abella, W. Wallace Covington, James B. Grace

Public Policy and Leadership Faculty Research

Question: How are the effects of mineral soil properties on understory plant species richness propagated through a network of processes involving the forest overstory, soil organic matter, soil nitrogen, and understory plant abundance? Location: North-central Arizona, USA. Methods: We sampled 75 0.05-ha plots across a broad soil gradient in a Pinus ponderosa (ponderosa pine) forest ecosystem. We evaluated multivariate models of plant species richness using structural equation modeling. Results: Richness was highest at intermediate levels of understory plant cover, suggesting that both colonization success and competitive exclusion can limit richness in this system. We did not detect a reciprocal positive …

Application Of The Empirical Mode Decomposition And Hilbert-Huang Transform To Seismic Reflection Data, Bradley M. Battista, Camelia C. Knapp, Tom Mcgee, Vaughn Goebel

Faculty Publications

Advancements in signal processing may allow for improved imaging and analysis of complex geologic targets found in seismic reflection data. A recent contribution to signal processing is the empirical mode decomposition (EMD) which combines with the Hilbert transform as the Hilbert- Huang transform (HHT). The EMD empirically reduces a time series to several subsignals, each of which is input to the same time-frequency environment via the Hilbert transform. The HHT allows for signals describing stochastic or astochastic processes to be analyzed using instantaneous attributes in the time-frequency domain. The HHT is applied herein to seismic reflection data to: (1) assess …

Paleomagnetic Dating Of Fault Slip In The Southern Rocky Mountains, Usa, And Itsimportance To An Integrated Laramide Foreland Strain Field, T. F. Wawrzyniec, Alexis K. Ault, J. W. Geissman, E. A. Erslev, S. D. Fankhauser

Geosciences Faculty Publications

The Laramide orogen of the U.S. Cordillera formed in the latest Cretaceous, and deformation lasted into the earliest Oligocene. Along and proximal to the eastern and northern margins of the Colorado Plateau, deformation associated with this event mainly took place along reactivated structures. Related tectonic models invoke some role for the plateau either as a stress guide transmitting compression to the foreland or as a freely rotating microplate. Models dominated by northward displacements of the Colorado Plateau also require covariance between timing and magnitude of dextral strike-slip deformation in the eastern domain and thrust deformation in the northern domain. Here …

Interdecadal-Decadal Climate Variability From Multi-Coral Oxygen Isotope Records In The South Pacific Convergence Zone Region Since 1650ad, Peipei Zhang

Geology Theses and Dissertations

Annual average oxygen isotope (δ18O) time series from five coral cores collected from Fiji and Tonga are used to construct a Fiji-Tonga Interdecadal-Decadal Pacific Oscillation (F-TIDPO) index of low frequency (>9yr and <55yr) climate variability in this area back to 1650 A.D. Presently, both Fiji and Tonga are located in the South Pacific Convergence Zone (SPCZ) salinity front region where the Interdecadal Pacific Oscillation (IPO) variation is most pronounced. We first demonstrate the consistency between this F-T IDPO index and a MSL pressure-based SPCZ Position Index (SPI) (1891-2000), thus verifying the ability of coral δ18O to record past interdecadal-decadal climatic variations in this region back to 1891. The F-T IDPO index is then shown to be synchronous with the IPO index (1856-2000), suggesting that this coral-based index effectively represents the interdecadal-decadal scale climate variance back to 1650. The consistently anti-phase spectrums of the F-T five-coral composite and the interdecadal-decadal components in equatorial Pacific coral δ18O series from Maiana [Urban et al., 2000] and Palmyra [Cobb et al., 2001] suggest that the simultaneous eastern expansion (western contraction) of the eastern salinity front of Western Pacific Warm Pool (WPWP) occurs at the same time as the northeast (southwest) movement of the SPCZ during a positive IPO (negative IPO) phase.

Outcrop Analog For Lower Paleozoic Hydrothermal Dolomite Reservoirs, Mohawk Valley, Ny, Brian E. Slater

Geology Theses and Dissertations

Geochemical analysis and field relations of linear dolomite bodies occurring in outcrop in the Mohawk Valley of New York suggest that they have undergone significant fault-related hydrothermal alteration. The dolomite occurs in the Lower Ordovician Tribes Hill Formation, which is regionally an early Ordovician shaley limestone with patchy dolomitization. The outcrop has an en echelon fault, fracture, and fold pattern. A 3D ground penetrating radar survey of the quarry floor has helped to map out faults, fractures, anticlines, synclines and the extent of dolomitization. Most of the dolomitization occurs in fault-bounded synclines or “sags” flanked by anticlines. The dolomite structures …

Different Modes Of Stress Transfer In A Strike-Slip Fault Zone: An Example From The North Anatolian Fault System In Turkey, Osman Bektaş, Yener Eyüboğlu, Nafi̇z Maden

Turkish Journal of Earth Sciences

The dextral North Anatolian Fault System (NAFS) extends for well over 1000 km from the compressive tectonic domain of eastern Anatolia into the broad and diverse tectonic domain of the western Anatolian, Marmara and Aegean regions. These different tectonic regimes are characterized by a narrow deformation zone in the east and a much broader deformation zone with multiple sub-parallel fault zones in the west. The spatial and temporal distribution of large historical and modern earthquakes (Mw>5) shows two distinctive macro-seismic zones in the eastern and western parts of the NAFS. The eastern macro-seismic zone, between the towns of Erzincan …

Constraints On The Origin Of The Balıkesir Thermal Waters (Turkey) From Stable Isotope (\Delta^{18}O, \Deltad, \Delta^{13}C, \Delta^{34}S) And Major-Trace Element Compositions, Hali̇m Mutlu

Turkish Journal of Earth Sciences

The Balıkesir thermal waters in northwestern Turkey have discharge temperatures in the range of 31.8-98.5 ºC, near neutral pH values of 6.40 to 8.40 and TDS contents between 327 and 2578 mg/l. Samples display variable chemical compositions changing from high-temperature Na_2SO_4-NaHCO_3 waters to warmer CaHCO_3 waters. Trace element concentrations of the waters show significant variation. Comparison between the concentrations of alkaline earth metals in waters and carbonate deposits reveals mobile behavior for Mg and Ba. The ratio of strontium to calcium concentrations in solid and liquid phases was found to be almost the same. Li/Cs and B/Cl ratios of waters …

A Mineralogical Note On Boulangerite, Geocronite And Yenerite From Near Işık Dağı (Kızılcahamam-Ankara), Turkey, W. E. Sharp, Mark Wieland, Steven K. Mittwede

Turkish Journal of Earth Sciences

Microprobe studies have facilitated recognition of the first documented occurrence of geocronite from Işık Dağı (Ankara, Turkey). While yenerite remains a discredited species along the PbS-Sb2S3 compositional join, our analyses show significant arsenic as did the original analyses for yenerite; thus, this name might be retained for arsenic-bearing varieties of boulangerite.

Stratigraphy And Geochemical Features Of The Early Miocene Bimodal (Ultrapotassic And Calc-Alkaline) Volcanic Activity Within The Ne-Trending Selendi Basin, Western Anatolia, Turkey, Yalçin Ersoy, Cahi̇t Helvaci

Turkish Journal of Earth Sciences

Western Anatolia has experienced thickening and orogenic collapse subsequent to the Eocene continent-arc collision. The early stage of the post-collisional volcanism in the region was thought to have produced widespread lavas and pyroclastic deposits of calc-alkaline basaltic andesite to rhyolite composition. However, in the Selendi Basin, one of the NE-trending basins in western Anatolia, there are two distinct volcanic unit compositions associated with the Lower Miocene sedimentary rocks: (1) a calc-alkaline, high-potassic felsic unit; and (2) alkaline, ultrapotassic lamproitic units, i.e. both are bimodal in character. The calc-alkaline felsic volcanic rocks (Eğreltidağ volcanic unit) are composed of wide-spread pyroclastic rocks …

Nature, Provenance And Relationships Of Early Miocene Palaeovalley Fills, Northern Adana Basin, Turkey: Their Significance For Sediment-Bypassing On A Carbonate Shelf, A. Sami̇ Derman, Kemal Gürbüz

Turkish Journal of Earth Sciences

The Gildirli Formation is the oldest Neogene rock unit in the Adana Basin and was formed prior to the regionally extensive Early Miocene marine transgression. These coarse clastic red-beds provide important evidence about the causes and early phases of filling in this large trough, because the Gildirli Formation sediments fill an irregular palaeotopography carved out of Palaeozoic and Mesozoic basement rocks. Detailed study of the Gildirli Formation reveals the existence of at least two alluvial fans supplied from different source areas. A northeastern fan, exposed around Gildirli Village, was fed by streams draining an area of ophiolitic mélange, Mesozoic and …

Strontium Isotopic And Micropalaeontological Dating Used To Help Redefine The Stratigraphy Of The Neotectonic Hatay Graben, Southern Turkey, Sarah J. Boulton, Alastair H. F. Robertson, Robert M. Ellam, Ümi̇t Şafak, Ulvi̇ Can Ünlügenç

Turkish Journal of Earth Sciences

In this paper we report for the Hatay Graben, new micropalaeotology, the first strontium dating and new sedimentology. The previous lack of a modern systematic stratigraphy was problematic for the study of the Hatay region. With the new data combined with the existing literature we evaluate and redefine the lithostratigraphy following international standards. The focus of this paper is on the Neogene cover rocks that record the transition from a regional carbonate shelf environment during Palaeocene to Eocene times, through late-stage continental collision, to recent continental rift tectonics that were initiated in the Middle Miocene and continue to operate to …
