Mapping Landscape Values Using Social Media, Lael Gilbert, Jordan W. Smith, Boris Van Zanten, Derek Van Berkel

All Current Publications

Social media data are providing scientists with a variety of new ways to examine how and why individuals value particular natural landscapes. In this fact sheet, we review cutting edge research that used millions of photos posted to Instagram, Flickr and Panaramio to examine which European landscapes individuals value most. The research is the first of its kind to use social media data to identify the public’s most valued landscapes across an entire continent. The research is also the first to compare the spatial agreement between geotagged imagery uploaded to different platforms.

Influence Of Porcine Plasma Supplementation On Gestating Sow Serum Igf-1 Concentration And Litter Weights, Mathew Vaughn, Crystal Serrano, Derris Burnett, Duane Davis, Jason Woodworth, John Gonzalez

Professional Agricultural Workers Journal

The objective of this pilot study was to determine the effect of dietary porcine plasma on circulating insulin-like growth factor 1 (IGF-1) concentrations in gestating sows and characteristics of their litters. Primiparous and multiparous sows were randomly allocated to two treatment groups of sows fed a basal diet or sows fed the basal diet plus 6 g of porcine plasma throughout gestation. On 4 periods during gestation and farrowing, blood was collected for IGF-1 analysis. After farrowing, gestation length, number born, birth weight, and total litter weight were recorded. There were no three-way or two-way interactions between treatments, day of …

Assessing Georgia Consumer Attitudes And Beliefs About Locally Or Regionally Produced Livestock And Products, Jannette R. Bartlett, Reem I. Omer, Akua Adu-Gyamfi, David Nii O. Tackie, Francisca A. Quarcoo, Bridget J. Perry

Professional Agricultural Workers Journal

Abstract

Interest in local and regional food production has been growing in the last few years. The study, therefore, assessed consumer attitudes and beliefs regarding local or regional livestock products. Data were obtained from a convenience sample of 384 participants from several counties of Georgia, and were analyzed by descriptive statistics, including chi-square tests. A majority of respondents thought using chemicals and additives in locally or regionally produced beef or goat meat was a serious or somewhat serious hazard. Consequently, many were willing to pay more for meat certified as locally or regionally produced. Furthermore, a majority agreed or strongly …

Comparison Of Four Harvesting Systems In A Loblolly Pine Plantation, John Klepac, Dana Mitchell

Professional Agricultural Workers Journal

Abstract

Felling and skidding operations were monitored while clearcut harvesting a 12-acre area of a 14-year old loblolly pine (Pinus taeda) plantation. The study area contained 465 trees per acre for trees 2.0 inches Diameter at Breast Height (DBH) and larger with a Quadratic Mean Diameter (QMD) of 7.26 inches. Two feller-bunchers (tracked and rubber-tired) and two skidders (conventional and large capacity) were paired to create four different harvesting systems which were randomly assigned to 3-acre units for evaluation of production rates and costs. Each system was balanced to determine the number of machines needed to minimize the …

Assessing Florida Consumer Attitudes And Beliefs About Locally Or Regionally Produced Livestock And Products, Akua Adu-Gyamfi, Reem I. Omer, Jannette R. Bartlett, David Nii O. Tackie, Bridget J. Perry

Professional Agricultural Workers Journal

Abstract

In recent years, consumer interest in locally or regionally produced foods has been growing. This study analyzed consumer attitudes and beliefs on local or regional livestock products in Florida. Data were collected from a convenience sample of 404 participants from counties in Florida. They were assessed by descriptive statistics, including chi-square tests. Most participants believed using chemicals in locally or regionally produced beef or goat meat was at minimum a somewhat serious hazard. Thus, many were willing to pay more for meat certified as locally or regionally produced. Moreover, most agreed or strongly agreed with statements on meat attributes. …

Sustainable Farm Practice: Study Of Total And Soluble Phosphorus In A Poultry Farm Equipped With Heavy Use Area Protection Pads, Dover, Delaware, Gulnihal Ozbay, Raju Khatiwada, Lathadevi K. Chintapenta, Eunice F. Handy, Stacy L. Smith

Professional Agricultural Workers Journal

Poultry litter contains high concentrations of water-soluble phosphorus and is readily transported in the farm run-off. This research aims to study the efficiency of heavy use area protection (HUAP) pads in decreasing litter spillage and phosphorous run-off at a Delaware poultry facility. Soil and water samples were analyzed for pH, total phosphorous, orthophosphate, and Mehlich III phosphorous throughout 2012. It has been hypothesized that the efficiency of HUAP pads would be reduced over time. Mehlich III phosphorus ranged from 22.82-200 mg/kg at site I, and 48.17 – 1179.6 mg/kg at site II, which were greater than the optimal soil concentrations. …

Grazing With Goats Changed The Woodland Plant-Species Composition During Summer, Rishi Khatri, Uma Karki, Jerry Bettis, Yubaraj Karki

Professional Agricultural Workers Journal

Abstract

Woodland grazing is a common practice in the Southeast; however, information is limited on its effects on the woodland plant-species composition. The study objective was to determine the effect of summer grazing on woodland plant-species composition. Before- and after-grazing observations were taken at the ground, mid, and high levels in three plots (1-acre each) along the pre-established transects. Kiko wethers (29, 6-8 months old, 26.8±0.67 kg body weight) were allowed to graze the plots after before-grazing observations were taken. After-grazing observations were taken immediately after the goats were moved out from the plots. Grazing showed a significant effect on …

Impact Of Climate Change On Corn Yields In Alabama, Pauline Welikhe, Joseph Essamuah-Quansah, Kenneth Boote, Senthold Asseng, Gamal El Afandi, Souleymane Fall, Desmond Mortley, Ramble Ankumah

Professional Agricultural Workers Journal

Abstract

The study used calibrated Crop Environment Resource Synthesis (CERES) maize (corn) model to simulate maize (corn) physiological growth processes and yields under 2045 and 2075 projected climate change scenarios for six representative counties in Alabama. The future climatologies for two emission scenarios Representative Concentration Pathway (RCP) 4.5 (medium) and RCP 8.5 (high) were developed based on the IPSL-CM5A-MR high resolution climate model. Average yield decreases of 19.5% and 37.3% were, respectively, projected under RCP 4.5 and RCP 8.5 for 2045, and average yield decreases of 32.5% and 77.8% were, respectively, projected under RCP 4.5 and RCP 8.5 for 2075. …

Antioxidant Activity Of Fermented Rice-Chili And Its Effect On Liver Lipid Peroxidation, Wei Cheng, Zhou Caiqiong, Ge Pingzhen, Zhu Lijuan, Xie Yueying

Food and Machinery

Selecting the for 15 days, which has the highest otal reducing power, and 60 days of the fermented Rice-Chili, which has the highest ORAC, as samples, The effects were studied, including the fermented Rice-Chili on the free radical DPPH· scavenging activity, oxidation inhibition rate of BSA, erythrocyte hemolysis and liver lipid peroxidation. Results showed that the DPPH· scavenging rate of samples fermented 15 days was better than 60 days and had a better protective effect from protein oxidative damage. However, the sample fermented 60 days had potential to promote the oxidation of BSA. Besides, both samples fermented 15 days and …
