Response of Retail Lawn Seed Products during Acute Drought and Recovery

Florence Breuillin‐Sessoms, Dominic Petrella, Daniel Sandor, Samuel J. Bauer et autres

Consumers often have multiple choices when purchasing retail lawn products in stores. In this study, we evaluated the acute drought performance of locally available retail lawn seed products (mixtures or blends) at two mowing heights of 2.5 and 3 inches. We hypothesized …

Variability in Creeping Bentgrass Cultivar Germinability as Influenced by Cold Temperatures

Garett C. Heineck, Samuel J. Bauer, Matthew J. Cavanaugh, Andrew Hollman et autres

Core Ideas Golf course superintendents often overseed winter-damaged areas with creeping bentgrass in the early spring when temperatures are not ideal for rapid germination. Typical spring temperatures in the upper Midwest were used to define treatments in a controlled environment study to …

Effects of De‐Icing Products on Putting Green Turf

Andrew Hollman, Garett C. Heineck, Kevin W. Frank, Samuel J. Bauer et autres

Prolonged ice cover of putting greens can lead to turfgrass crown death. De‐icing products can aid in ice removal, but variations in ice thickness and putting green topography increase the likelihood these products will contact and damage ice‐free turfgrass areas. The objective …

Wetting Agent Influence on Putting Green Surface Firmness

Samuel J. Bauer, Matthew J. Cavanaugh, Brian P. Horgan

Soil wetting agents are commonly used in the golf course industry for managing soil moisture. Recently, there has been an interest in the influence wetting agents have on the firmness characteristics of putting surfaces. To date, there has been no established relationship …

The Great Lakes School of Turfgrass Science: A Nine-State Online Collaboration to Improve the Turfgrass Short Course

Paul Koch, Douglas J. Soldat, Brian P. Horgan, Samuel J. Bauer

Increasing costs and decreasing numbers of university Extension faculty have made it difficult to provide quality turfgrass short course education. In response, faculty from nine institutions collaborated to develop the Great Lakes School of Turfgrass Science. This 12-week online course provides students …

Effects of Low Temperatures on Nitrogen Uptake, Partitioning, and Use in Creeping Bentgrass Putting Greens

Samuel J. Bauer, Brian P. Horgan, Douglas J. Soldat, Daniel T. Lloyd et autres

Late‐fall nitrogen (N) fertilization is commonly recommended for turfgrass nutrition in the Upper Midwest, although research identifying its efficiency and subsequent benefit is lacking for creeping bentgrass (Agrostis stolonifera L.). The objectives of this research were to evaluate the efficiency and agronomic …

Wachstum von Winterweizen bei Gärrestdüngung undunterschiedlichen Kleegrasmanagement

Hans Jürgen Reents, Samuel J. Bauer, Kain Levin

Wheat performance and yields were tested in field an experiment regarding pre-crop management and fertilization with biogas digestate. Digestate fertilization led to an increased nitrogen uptake, higher yield and higher protein content. The yield increases were due to denser stands related to …

Genetic deletion of TNFα inhibits ultraviolet radiation-induced development of cutaneous squamous cell carcinomas in PKCε transgenic mice via inhibition of cell survival signals

Ashok Singh, Anupama Singh, Samuel J. Bauer, Deric L. Wheeler et autres

Protein kinase C epsilon (PKCε), a Ca(2+)-independent phospholipid-dependent serine/threonine kinase, is among the six PKC isoforms (α, δ, ε, η, μ, ζ) expressed in both mouse and human skin. Epidermal PKCε level dictates the susceptibility of PKCε transgenic (TG) mice to the …

Abstract 4570: Genetic deletion of TNFα in mice inhibits UVR-induced development of cutaneous squamous cell carcinomas via suppression of its own receptors and associated signals to epidermal cell survival

Ashok Singh, Anupama Singh, Samuel J. Bauer, Ajit Kumar Verma

Abstract Skin cancer is the second most common malignancy encountered in the U.S. with an expected diagnosis of 1.3 million new cases of non-melanoma skin cancer each year. Cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the most common …
