Influence Of Microbial Priming And Seeding Depth On Germination And Growth Of Native Wildflowers, Daniela Barrera, Juan Luera, Kaitlynn Lavallee, Pushpa Soti

School of Earth, Environmental, & Marine Sciences Faculty Publications

Background: Using native wildflowers for restoring marginal lands has gained considerable popularity. Establishment of wildflowers can be challenging due to several environmental factors. Restoring the microbial community in degraded habitats can potentially result in the native plant performance and habitat restoration. This study was conducted to investigate the impact of native soil microbes and seeding depth on germination of south Texas native wildflowers. Two wildflower species, Ratibida columnifera (Nutt.) (Mexican Hat) and Verbesina encelioides (Cav.) (cowpen daisy), were treated with microbial wash extracted from native soils, and germination rate was recorded for 14-day period. We further analyzed the growth, biomass …

Options For Managing Thin Alfalfa Stands, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the highest yielding, highest quality hay crop grown in Kentucky. Well cured alfalfa and alfalfa-grass hay is in high demand for dairy and in particular, horse owners. Alfalfa stands in Kentucky remain productive from four to as long as 8 years or more depending on several factors. Long stand life is favored by:

1. Using an improved variety with high resistance to the major diseases of Kentucky and that is proven to be high yielding in relevant trials such as conducted at the University of Kentucky.
2. Deep, well drained soils,
3. Soils that have been limed to pH 6.8 and …

What Does Past Research Tell Us About Alfalfa Drying Rates?, Jordyn Bush

Kentucky Alfalfa and Stored Forage Conference

Today I’m going to give everyone a brief overview of a literature review I’ve been working on at the request of a local farmer. While writing this literature review, I looked at the factors that influence how quickly alfalfa dries down. I also read past research that has been conducted in an attempt to predict when hay will be dry or how long it will take to do so. The ultimate goal of this literature review was to determine the feasibility of creating some sort of hay drying prediction or forecasting system for Kentucky.

Measuring Forage Quality: Sampling And Interpretation, Christopher D. Teutsch

Kentucky Alfalfa and Stored Forage Conference

Forage quality is often described with terms like crude protein, neutral detergent fiber, acid detergent fiber, in vitro dry matter digestibility, neutral detergent fiber digestibility, and the list goes on! Perhaps the best definition of forage quality is the ability of a forage to produce a desired animal response. This concept is quite simple, but the process of getting from forage to actual animal performance is quite complex (Figure 1). It is important to realize that there is no perfect measure of forage quality. However, measures that are based on fiber digestibly provide better estimates of energy and dry matter …

Snow Avalanche Detection And Source Constraints Made Using A Networked Array Of Infrasound Sensors, J. B. Johnson, J. F. Anderson, H. P. Marshall, S. Havens, L. M. Watson

Geosciences Faculty Publications and Presentations

We studied a triggered snow avalanche (∼60 s in duration and with ∼1,100 m run-out) using a network of infrasound arrays and time-synced video, with the objective of understanding the relationship between infrasound generation and flow dynamics. Using standard array processing techniques, we compared the infrasound source back azimuths with the avalanche flow path identified by frame-differenced, geo-referenced video. Results show that infrasound records begin with direct arrivals followed by echoes from the avalanche-triggering explosions and these decay within 35 s of the detonations. Subsequent infrasound, which lasts 20–30 s, could then be attributed exclusively to the avalanche. These infrasound …

Soil Quality Indices As Affected By Long-Term Burning, Irrigation, Tillage, And Fertility Management, Helen C.S. Amorim, Amanda Ashworth, Kristofor R. Brye, Brian J. Wienhold, Mary C. Savin, Phillip R. Owens, Sergio Silva

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Understanding the impacts of long-term agricultural practices on soil quality (SQ) is key for sustaining agroecosystem productivity. This study investigated conventional and no-tillage (NT), residue burning and no burning, residue level (high and low), and irrigation (irrigated and dryland) effects on soil properties, SQ, and crop yields following 16 yr of a wheat (Triticum aestivum L.)–soybean [Glycine max (L.) Merr.] double-crop system via the Soil Management Assessment Framework (SMAF). A field experiment was conducted in the Lower Mississippi River Delta region on a silt-loam soil. Bulk density, soil organic C (SOC), total N (TN), pH, electrical conductivity (EC), …

Characterizing Nematode Communities In Carrot Fields And Their Bioindicator Role For Soil Health, A. Habteweld, D. Brainard, A. Kravchencko, Parwinder Grewal, H. Melakeberhan

School of Earth, Environmental, & Marine Sciences Faculty Publications

Plant-parasitic nematodes (PPN) are known to reduce quality and yield of carrot (Daucus carota var. sativus). Efficient nematode management begins with identifying the predominant PPN present in a given field before taking any management decisions. The management decisions should also consider suppression of PPN and promotion of beneficial nematodes represented by bacterivores, fungivores, omnivores, and predators to improve soil health conditions. We selected four carrot fields suspected to have PPN problems in Mason and Oceana counties in Michigan, USA. The counties are located in the major carrot-producing regions of Michigan. These sites have not been previously sampled for …

On The Genesis Of Aluminum-Rich Speleothems In A Granite Cave Of Nw Spain, Jorge Sanjurjo-Sanchez, Carlos Arce Chamorro, Juan Ramón Vidal Romaní, Marcos Vaqueiro-Rodríguez, Victor Barrientos, Joeri Kaal

International Journal of Speleology

Granite massifs often contain caves, with dimensions ranging from a few meters up to 1,000 m, also referred to as pseudokarst. The speleothems in such caves are mostly composed of either Si-rich (commonly opal-A) or Al-rich authigenic mineraloids. Whereas the formation and geochemical composition of opal-A biospeleothems have been studied and are fairly well understood, knowledge on the Al-rich analogues is scarce. This work reports for the first time a study on the composition, accretion process, age and growth rate of an Al-rich speleothem type flowstone from the A Trapa Cave System (Galicia, NW Spain), developed in a granite cave. …

Many research and monitoring networks in recent decades have provided publicly available data documenting environmental and ecological change, but little is known about the status of efforts to synthesize this information across networks. We convened a working group to assess ongoing and potential cross-network synthesis research and outline opportunities and challenges for the future, focusing on the US-based research network (the US Long-Term Ecological Research network, LTER) and monitoring network (the National Ecological Observatory Network, NEON). LTER-NEON cross-network research synergies arise from the potentials for LTER measurements, experiments, models, and observational studies to provide context and mechanisms for interpreting NEON …

From Hector Mine M7.1 To Ridgecrest M7.1 Earthquake. A Look From A 20-Year Perspective, Sergey Pulinets, Marina Tsidilina, Dimitar Ouzounov, Dmitry Davidenko

Mathematics, Physics, and Computer Science Faculty Articles and Research

The paper provides a comparative analysis of precursory phenomena in the ionosphere and atmosphere for two strong earthquakes of the same magnitude M7.1 that happened in the same region (North-East from Los Angeles) within a time span of 20 years, the Hector Mine and Ridgecrest earthquakes. Regardless of the similarity of their location (South-Eastern California, near 160 km one from another), there was one essential difference: the Hector Mine earthquake happened during geomagnetically disturbed conditions (essential in the sense of ionospheric precursors identification). In contrast, the quiet geomagnetic conditions characterized the period around the time of the Ridgecrest earthquake. The …
