Internet Of Things In Water Management And Treatment, Abdul Salam

Faculty Publications

The goal of the water security IoT chapter is to present a comprehensive and integrated IoT based approach to environmental quality and monitoring by generating new knowledge and innovative approaches that focus on sustainable resource management. Mainly, this chapter focuses on IoT applications in wastewater and stormwater, and the human and environmental consequences of water contaminants and their treatment. The IoT applications using sensors for sewer and stormwater monitoring across networked landscapes, water quality assessment, treatment, and sustainable management are introduced. The studies of rate limitations in biophysical and geochemical processes that support the ecosystem services related to water quality …

Contributions In Puerto Rico To Bean, Phaseolus Spp., Research, James S. Beaver, Consuelo Estévez De Jensen, Phillip N. Miklas, Timothy G. Porch

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Most literature reviews focus on a specific topic. The purpose of this paper, however, is to review the contributions made by a multidisciplinary team of researchers at a specific location (Puerto Rico) over a period of several decades. This paper documents bean research of the University of Puerto Rico and the USDA-ARS Tropical Agriculture Research Station during the past century. The following illustrates the merits of continuity of effort in research and shows that research often follows a logical sequence of actions to solve problems related to genetic improvement as well as to study biotic and abiotic factors that affect …

Comparison Of Sheep, Goats, And Calves As Infection Models For Mycobacterium Avium Subsp. Paratuberculosis, Judith R. Stabel, J. P. Bannantine, Jesse M. Hostetter

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Animal infection models to study Mycobacterium avium subsp. paratuberculosis (MAP) infection are useful for evaluating the efficacy of vaccines and other therapeutics for the prevention or treatment of infection. The goal of the present study was to compare smaller ruminants, sheep and goats, with calves as infection models. Neonatal sheep, goats, and calves (n = 4) received 109 cfu of a cattle isolate of MAP in milk replacer on days 0, 3 and 6 in a 12-month study and sampled monthly thereafter. Results demonstrated a robust antigen-specific IFN-γ response at 90 days post-inoculation for sheep and goats, with lower responses …

Forage Breeding. From Forages: The Science Of Grassland Agriculture, Volume Ii, Michael D. Casler, Kenneth P. Vogel

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Plant breeding is human-directed evolution.This process has been used to develop all major crops and their respective races, strains, or cultivars. Although humans have successfully manipulated the genetic resources of plants for several thousand years, the science of genetics and breeding was not developed until the twentieth century. Breeding work on a few forage crops began in the early part of the twentieth century (Wilkins and Humphreys 2003). Initial work was focused on developing strains that had improved establishment, persistence, high forage yields, and good insect and disease resistance. These remain essential attributes of cultivated forages (Burton 1986). Since the …

Estimating Corn Emergence Date Using Uav-Based Imagery, Chin Nee Vong, Stirling A. Stewart, Jianfeng Zhou, Newell R. Kitchen, Kenneth A. Sudduth

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Assessing corn (Zea Mays L.) emergence uniformity soon after planting is important for relating to grain production and for making replanting decisions. Unmanned aerial vehicle (UAV) imagery has been used for determining corn densities at vegetative growth stage 2 (V2) and later, but not as a tool for detecting emergence date. The objective of this study was to estimate days after corn emergence (DAE) using UAV imagery. A field experiment was designed with four planting depths to obtain a range of corn emergence dates. UAV imagery was collected during the first, second and third weeks after emergence. Acquisition height was …

Estimation Of Maize Yield And Effects Of Variable-Rate Nitrogen Application Using Uav-Based Rgb Imagery, Meina Zhang, Jianfeng Zhou, Kenneth A. Sudduth, Newell R. Kitchen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Accurate crop yield estimation is important for agronomic and economic decision-making. This study evaluated the performance of imagery data acquired using a unmanned aerial vehicle (UAV)-based imaging system for estimating yield of maize (Zea mays L.) and the effects of variable-rate nitrogen (N) application on crops. Images of a 27-ha maize field were captured using a UAV with a consumer-grade RGB camera flying at ~100 m above ground level at three maize growth stages. The collected sequential images were stitched and the Excess Green (ExG) colour feature was extracted to develop prediction models for maize yield and to examine the …

Automatic Seeder, Zachary Bunting, Nicholas Muscarella, Trevor Tout, Dalton Denny

Williams Honors College, Honors Research Projects

Our Senior Design Project is the construction and implementation of an automatic seeder that is to be used in the agricultural industry. The automatic seeder is being designed to eliminate prevalent issues within the process of planting seeds by hand, such as labor requirements and inconsistent operations. The seeder is meant to reduce time spent on planting seeds and place them in an efficient manner for optimal growth conditions.

This project will require several specific research questions to be addressed in the form of application and good usability. We will investigate the method of planting the seed, the conveyor track …

Assessing Agricultural Risk Management Using Historic Crop Insurance Loss Data Over The Ogallala Aquifer, Julian Reyes, Emile Elias, Erin M.K. Haacker, Amy Kremen, Lauren Parker, Caitlin Rottler

Department of Earth and Atmospheric Sciences: Faculty Publications

Much of the agricultural production in the Ogallala Aquifer region relies on groundwater for irrigation. In addition to declining water levels, weather and climate-driven events affect crop yields and revenues. Crop insurance serves as a risk management tool to mitigate these perils. Here, we seek to understand what long-term crop insurance loss data can tell us about agricultural risk management in the Ogallala. We assess patterns and trends in crop insurance loss data from the U.S. Department of Agriculture Risk Management Agency. Indemnities, or insurance payments, totaled $22 billion from 1989–2017 for the 161 counties that overlie the Ogallala Aquifer. …

Central Wheatbelt Biosecurity Association Inc. Annual Report 2019/20, Central Wheatbelt Biosecurity Association Inc.

Recognised Biosecurity Group Annual Reports

The 2019/20 financial year has produced exceptionally good results for the CWBA, particularly in reducing stock attacks by Wild Dogs. This has been the main focus of our efforts and the results speak for themselves. This has been our second year with a Declared Pest Rate and although we endured a rate rise, I feel we still have overwhelming support within the CWBA area. The system of using a DPR to control declared pests may not be perfect, but we feel it’s the fairest and most equitable way to control pests which roam free and don’t respect property boundaries. It …
