Managing Complexity In Modern Farming, Ross Kingwell

Natural Resources Research Articles

Modern farming in Australia is no longer simple. Farms are large, multi-enterprise businesses underpinned by expensive capital investments, changing production technologies, volatile markets and social challenges. The complexity of modern broadacre farming leads to the question: what is the nature of the relationship between farm business complexity and farm profitability? This study uses bioeconomic farm modelling and employs eight measures of complexity to examine the profitability and complexity of a wide range of broadacre farming systems in Australia. Rank order correlations between farm profitability and each measure of complexity show inconsistent relationships, although the most profitable farming systems are found …

Modeling Gross Primary Production Of Irrigated And Rain-Fed Maize Using Modis Imagery And Co2 Flux Tower Data, Joshua L. Kalfas, Xiangming Xiao, Diana X. Vanegas, Shashi B. Verma, Andrew E. Suyker

School of Natural Resources: Faculty Publications

Abstract

Information on gross primary production (GPP) of maize croplands is needed for assessing and monitoring maize crop conditions and the carbon cycle. A number of studies have used the eddy covariance technique to measure net ecosystem exchange (NEE) of CO₂ between maize cropland fields and the atmosphere and partitioned NEE data to estimate seasonal dynamics and interannual variation of GPP in maize fields having various crop rotation systems and different water management practices. How to scale up in situ observations from flux tower sites to regional and global scales is a challenging task. In this study, the Vegetation …

Measurement Of Particle Size Distribution In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang

Faculty Publications

The majority of the research in animal buildings has been on measured concentrations of contaminants that the workers and animals are exposed to; emission measurements have only gained attention in recent years due to potential federal regulations on air quality emissions from animal feeding operations (AFOs). The contribution of AFOs to ambient PM10 and PM2.5 entails reliable measurement of particle size distribution. The objective of this study was to measure and compare the size distribution of particulate matter (PM) at multiple locations inside and at the exhausts of a wean‐to‐finish commercial swine building. The particle size distribution was measured by …

Spatial And Temporal Distributions Of Dust And Ammonia Concentrations In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang

Faculty Publications

Pollutants, especially dust, are rarely uniformly distributed within ventilated air spaces due to non‐uniform flow fields, particle inertia, gravitational settling, and diffusion. Thus, selecting suitable sampling locations for representative sampling is a challenge. The objective of this study was to determine the spatial and temporal distributions of dust and ammonia concentrations(NH3) in a swine building. Results of this study are useful in the design of sampling strategies that require limited sampling locations and in studying pollutant transport. This study was conducted in a commercial swine building in Illinois. The total suspended particulate (TSP) matter and ammonia concentrations were measured at …

Caring For Compromised Cattle: Assessing Animals At Risk

Nebraska Beef Quality Assurance Program

Cattlemen have long recognized the need to properly care for their livestock. Sound animal husbandry practices – based on research and decades of practical experience – are known to impact the well-being of cattle, individual animal health and herd productivity. There is no doubt that producers work hard to ensure that their cattle are properly cared for throughout all stages of production. Unfortunately, it’s a fact of raising cattle that some animals will become injured to the extent that they are unable to stand or walk without assistance.

Developing A Biophysical Model To Determine The Minimum Water Requirement For Irrigating Known Crops, Robyn M. Williams, Lahaouri Bounoua

STAR Program Research Presentations

This research is to determine the minimum amount of irrigation needed to grow 75 crops in semi-arid regions. The number of days each crop spends in their developmental stages and the amount of water needed to grow these crops will be gathered and then used to create a mathematical model that will calculate how much water certain crops need at their various developmental stages. From this model, we will be able to quantify the minimum water requirement in order to limit the amount of water that is possibly being wasted due to over irrigating agricultural areas.

Panhandle Research and Extension Center

Lepidopteran stem borers were collected from switchgrass, Panicum virgatum L., tillers showing symptoms of infestation at seven locations in Illinois and Iowa, with additional observations made on larval and adult activity. Blastobasis repartella (Dietz) (Coleophoridae), whose only known host is switchgrass, was common in plots grown for >5 yr, whereas the polyphagous stalk borer, Papaipema nebris (Guenée) (Noctuidae), was abundant in newly established (i.e., first- and second year) switchgrass. Haimbachia albescens Capps (Crambidae) was collected from two locations in Illinois, making switchgrass the first known host for this species. Entry holes made by B. repartella and H. albescens were usually …

A Rare Epidemic Of Sugar Beet Seedling Rust In Nebraska, Robert M. Harveson

Panhandle Research and Extension Center

Sugar beet seedling rust, caused by Puccinia subnitens, is a disease that has rarely been observed in sugar beet production. The pycnial and aecial stages occur on sugar beets, while the uredial and telial stages infect the primary host, inland saltgrass (Distichlis spicata). In mid-May 2009, lesions indicative of sugar beet seedling rust were found on young sugar beet plants in a field near Bayard, Nebraska. Because of the continued cool weather with above average precipitation throughout May, a survey of sugar beet production fields in western Nebraska was conducted between late-May and mid-June to further document …

Feedlot Manure Handling And Application Strategies On Surface Runoff Of Artificial Hormones Applied To Rowcrop Fields, Sagor Biswas, William L. Kranz, Shannon L. Bartelt-Hunt, Terry L. Mader, Charles A. Shapiro, David P. Shelton, Daniel D. Snow, David Tarkalson, Simon Van Donk, Tian Zhang, Steve Ensley

West Central Research and Extension Center, North Platte

Hormones are essential to the function and propagation of almost all organisms, yet the environmental fate of hormones is not well understood. Because these substances are so common in nature, the question is not whether they will be found, but rather at what concentrations and in what form (biologically active or inactive) will they be found. The objective of this research was to determine the effect of manure handling and application strategies on artificial hormone losses in runoff through the use of simulated rainfall. In 2008, rainfall simulations were conducted at the Haskell Agricultural Laboratory near Concord, NE (Latitude: 42 …

West Central Research and Extension Center, North Platte

Two hundred ninety-nine Angusbased, nulliparous heifers (253 ± 2 kg initial BW) from 3 production years were utilized to compare traditional postweaning dry lot (DL) development with a more extensive winter grazing system utilizing a combination of corn residue and winter range (EXT). Heifers developed in the DL were offered a common diet after the weaning period for 208 d in yr 1, 194 d in yr 2, and 150 d in yr 3 until breeding. Heifers developed in EXT grazed corn residue for 135 d in yr 1, 106 d in yr 2, and 91 d in yr 3, …

Applications Of Weps And Sweep To Non-Agricultural Lands, John Tatarko, David G. Walker, Simon Van Donk

West Central Research and Extension Center, North Platte

Soil erosion by wind is a serious problem throughout the United States and the world. Dust from wind erosion obscures visibility and pollutes the air. It fills road ditches where it impacts water quality, causes automobile accidents, fouls machinery, and imperils animal and human health. Dust and specifically particulate matter less than 10 microns (PM10), is regulated by the US-EPA National Ambient Air Quality Standards. The Wind Erosion Prediction System (WEPS) model was developed by the USDA Agricultural Research Service, primarily for the USDA Natural Resources Conservation Service to simulate wind erosion and develop conservation plans on cultivated agricultural lands. …

The Role Of Light And Soil Moisture In Plant Community Resistance To Invasion By Yellow Starthistle (Centaurea Solstitialis), Stephen L. Young, Guy B. Kyser, Jacob N. Barney, Victor P. Claassen, Joseph M. Ditomaso

West Central Research and Extension Center, North Platte

To resist establishment by an invasive plant, a community may require one or more species functionally similar to the invader in their resource acquisition pattern. In this study, communities consisting of native winter annual forbs, non-native annual grasses, native perennials, or a combination of the two native communities were established with and without Centaurea solstitialis to determine the effect of soil moisture and light availability on plant community invasion resistance. The annual plant communities were unable to resist invasion by C. solstitialis. In the native winter annual forb community, senescence in late spring increased light penetration (>75%) to …

Two locations on a commercial ranch in the Nebraska Sandhills were used to determine the effects of maternal nutrition on male progeny. Crossbred, spring-calving, multiparous cows were managed in a year-round grazing system. Cows at one location (yr 1 = 754; yr 2 = 700) received the equivalent of 0.95 kg/d (DM; 31.6% CP; HN) of supplement, and cows at the second location (yr 1 = 673; yr 2 = 766) received 0.37 kg/d (DM; LN) of the same supplement delivered 3 times weekly while grazing winter range from December through February. After weaning, a random group (yr 1 = …

Determining Optimal Fungicide Timing For Rhizoctonia Root Rot Of Sugar Beet In Nebraska Based On Soil Temperatures, Robert M. Harveson, Kathleen A. Nielsen, C. Clay Carlson

Panhandle Research and Extension Center

Rhizoctonia root and crown rot, caused by Rhizoctonia solani, is the most widespread, consistently found, and damaging sugar beet disease in Nebraska. It is capable of causing both a seedling disease and two different phases of root rot later in season. These two phases include a crown rot, and a tip rot of the tap root originating beneath the soil surface. Since there are several diverse forms (root rot phases) of the disease observed in Nebraska, it has been difficult to make fungicide recommendations based only on plant growth stage or chronological time of the season. In the attempt …
