Investigating Bat Activity In Various Agricultural Landscapes In Northeastern United States, Katherine Harms, Emmanuel Omondi, Atanu Mukherjee
Agricultural and Environmental Sciences Faculty Research
Bats are estimated to provide between $3.7 and $53 billion annually in ecosystem services in the U.S.A. Determining how bats use land for foraging is important in planning agricultural landscapes to increase their presence and role in insect pest control. A research project was established in 2016 and 2017 to determine bat populations and activity differences between different land use management systems. Bat activity was monitored in 10 conventionally and organically managed systems in the presence of, and at a distance from the tree line. Two acoustic monitoring devices were used to record ultrasonic echolocation calls of bats. Organic systems …

Safety First Risk Preferences And Post-Harvest Grain Marketing A Context-Rich Lab Experiment, Stamatina Stamatina, Simanti Banerjee, Cory Walters
Cornhusker Economics
Improving our understanding of the influence of risk- preferences on decision making represents an important objective for understanding behavior, designing policy and decision making theory. A natural place this problem persists is in the marketing of grain (Kastens and Dhuyvetter, 1999). Grain marketing research has primarily focused on the use of different marketing techniques that result in lower price risk and, therefore, lower-income risk (Musser, Patrick, Eckman, 1996). However, the extent to which the theoretical findings from these studies are relevant to real-world applications is not clear (Brorsen and Irwin, 1996; Garcia and Leuthold, 2004). While reducing income risk is …

Genetic Parameters Of Growth And Adaptive Traits In Aspen (Populus Tremuloides): Implications For Tree Breeding In A Warming World, Chen Ding, Andreas Hamann, Rong-Cai Yang, Jean S. Brouard
Aspen Bibliography
Aspen (Populus tremuloides Michx) is a widespread commercial forest tree of high economic importance in western Canada and has been subject to tree improvement efforts over the past two decades. Such improvement programs rely on accurate estimates of the genetic gain in growth traits and correlated response in adaptive traits that are important for forest health. Here, we estimated genetic parameters in 10 progeny trials containing >30,000 trees with pedigree structures based on a partial factorial mating design that includes 60 half-sibs, 100 full-sib families and 1,400 clonally replicated genotypes. Estimated narrow-sense and broad-sense heritabilities were low for height …

Crop breeders are looking for tools to facilitate the screening of genotypes in field trials. Remote sensing-based indices such as normalized difference vegetative index (NDVI) are sensitive to biomass and nitrogen (N) variability in crop canopies. The objectives of this study were (i) to determine if proximal sensor-based NDVI readings can differentiate the yield of winter wheat (Triticum aestivum L.) genotypes and (ii) to determine if NDVI readings can be used to classify wheat genotypes into grain yield productivity classes. This study was conducted in northeastern Colorado in 2010 and 2011. The NDVI readings were acquired weekly from March to …

Variable Frequency Drives For Irrigation Pumps, Matt Yost, Tom Young, Niel Allen, Dustin Larson, Jonathan Holt
All Current Publications
Many irrigation systems have variable flow and pressure needs. Variable frequency drives (VFDs) are electric controllers that vary the speed of the pump motor, allowing the pump to respond smoothly and efficiently to fluctuations in flow and/or pressure demand (Stover, 2019). They are also sometimes referred to as variable speed drives (VSD). When installed correctly in the right applications, they can effectively reduce energy costs, decrease electrical system stress, and extend the life of a pump.Due to their effectiveness, many energy companies and governments cost-share or incentivize their use.This can sometimes lead to VFDs installed on pumps where costs …

Irrigation and Melioration
The article presents the issues of energy saving, which are becoming increasingly relevant due to the constant increase in tariffs and the introduction of the demands on energy efficiency and energy conversation. To save energy at pumping units, the characteristics of controlling the electric drive of pumping stations with frequency-controlled control are considered. For adequate adjustment by the technological process of water movement and power supply, corresponding analytical dependencies are obtained. An analysis of the physical expressions of water pumping processes allowed us to determine energy-saving modes of operation and technologies for improving the efficiency of equipment.
