Atrazine Runoff In The Blue River Basin: Geomorphology, Rainfall, And Agronomic Practices, Kundan Dhakal
Atrazine Runoff In The Blue River Basin: Geomorphology, Rainfall, And Agronomic Practices, Kundan Dhakal
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Atrazine concentrations in the Big Blue River Basin (BRB) in Nebraska and Kansas periodically exceed the U.S. EPA Maximum Contaminant Level (MCL) of 3 µg L-1. The present study is focused on watershed variables influencing surface runoff of atrazine. The assessment includes the impact of corn and sorghum planting progress (indicating atrazine application), rainfall, antecedent soil water content, and soil restrictive layer on stream-measured weekly atrazine load in independent BRB subwatersheds for 1997 - 2004. Maximum atrazine loading occurred after most of the corn had been planted but during sorghum planting from mid-May to early June, immediately following …

Wetland Basins For Saline Drainage Water Disposal Bodallin And Elachbutting Catchments, Eastern Wheatbelt, Western Australia, P De Broekert, N Coles
Resource management technical reports
This report provides an assessment of two large deep drainage schemes within the lower reaches of the Bodallin and Elachbutting Catchments nearby Merredin in Western Australia, wherein groups of isolated wetland basins have been utilised for evaporative saline drainage water disposal. In both cases, the storage capacity of the basins has been exceeded, leading to flooding and death of the surrounding native vegetation.
Reducing Nutrient Discharge From Agriculture Through The Implementation Of Bmps – How Far Can We Go?, David Weaver, Simon Neville, Robert Summers, Martin Clarke
Reducing Nutrient Discharge From Agriculture Through The Implementation Of Bmps – How Far Can We Go?, David Weaver, Simon Neville, Robert Summers, Martin Clarke
Conference papers and presentations
Algal blooms in south west Western Australia are a symptomatic response to excess nutrient input. Whilst a range of Best Management Practices (BMPs) are available to address the causes of nutrient pollution, most investment has been directed towards symptoms. In order to treat nutrient pollution causes effectively it is important to evaluate possible nutrient reductions and costs, and to determine whether accrued benefits can influence BMP adoption. Models were developed for catchments near Albany (south coast of Western Australia), and for the Peel-Harvey catchment (70 km south of Perth) to estimate costs and benefits of implementing conventional BMPs in scenarios …
Seasonal Aeration Rates For The Eastern United States Based On Long-Term Weather Patterns, Michael D. Montross, Samuel G. Mcneill, Thomas C. Bridges
Seasonal Aeration Rates For The Eastern United States Based On Long-Term Weather Patterns, Michael D. Montross, Samuel G. Mcneill, Thomas C. Bridges
Biosystems and Agricultural Engineering Faculty Publications
Most aeration fans are sized to produce a minimum airflow rate of 0.1 m3/min/t (0.1 cfm/bu) in on-farm grain storage structures. At this airflow rate a significant amount of time is required to move a cooling front completely through a bin. The desired grain temperature and prevailing weather conditions will have a significant effect on required fan size. Thirty years of weather data were analyzed for the eastern United States to determine the amount of time available in temperature windows between 0 to 15.C and 0 to 17.C. Contour maps were generated with ArcMap 8.3 for the percentage …

Pastoral Risk Management In Southern Ethiopia: Observations From Pilot Projects Based On Participatory Community Assessments, D. Layne Coppock, Solomon Desta, Seyoum Tezera, Rancis K. Lelo
Environment and Society Faculty Publications
The Borana pastoral system has come under increasing pressure as human populations grow and per capita availability of resources declines. Livestock exhibit large, periodic die-offs that threaten wealth accumulation and food security. Several types of interventions may improve risk management here. For example, there may be opportunity for some pastoralists to diversify their livelihoods. Here we report on a community-based process involving pilot projects begun since 2000. We have embraced Participatory Rural Appraisal (PRA) and Action Research (AR) as tools for investigation and empowerment of local people. Full PRAs were conducted for semi-settled communities, located near towns, to identify priority …

Science-Based Organic Farming: A Resource For Educators, Charles A. Francis, Mindi Schneider, Brad Kindler
Science-Based Organic Farming: A Resource For Educators, Charles A. Francis, Mindi Schneider, Brad Kindler
Publications from the Center for Applied Rural Innovation (CARI)
Organic farming is an important and growing part of the United States food system. The organic sector has grown by at least 20% per year for the past two decades, and currently shows no indication of slowing in this growth. There is increasing consumer concern about where and how food is produced, and people want to be assured access to safe and healthy food products. Interest and concern about food security, and discussion about the merits of a local food system as compared to the vulnerable globalized marketplace are also becoming increasingly important. In Nebraska we have only limited local …

Narrogin Townsite Test Pumping Results 2003, Louise Hopgood
Narrogin Townsite Test Pumping Results 2003, Louise Hopgood
Resource management technical reports
Test pumping of a production bore in Narrogin took place for 24 hours in August 2003. Data generated by the test pumping was analysed along with groundwater monitoring, climate and geological data. Laboratory analyses of water samples from the production bore indicate very high levels of salinity and hardness which may lead to severe scaling and corrosion of pumps, pipes and pipe fittings.

Groundwater Study Of The York Townsite, Edward K. Crossley, Department Of Agriculture, Western Australia. Rural Towns Program
Resource management technical reports
A groundwater study was carried out in the townsite of York in April-May 2002. The prupose was to collect information on local groundwater systems that could be used to develop a salinity management strategy. The study included a driling program, which established a network of monitoring bores. Seventy-seven monitoring bores were installed at 32 sites as well as a production bore for testing aquifer properties.

Groundwater Investigation Buntine-Marchagee Natural Diversity Recovery Catchment, Russell John Speed, M Strelein
Resource management technical reports
A groundwater investigation was initiated in the Buntine-Marchagee Natural Diversity Recovery Catchment 200 kms north-east of Perth, Western Australia in 2002. The investigation aimed to install a regional groundwater monitoring network and characterise the regolith throughout the catchment. Drill site selection was based on establishing a series of transects to enable construction of hydrogeological cross-sections to enhance conceptual understanding of the catchment.
Grass Or Trees? Performance Of Riparian Buffers Under Natural Rainfall Conditions, Australia, Lucy Mckergow, I Prosser, R Grayson, David Weaver, D Heiner
Grass Or Trees? Performance Of Riparian Buffers Under Natural Rainfall Conditions, Australia, Lucy Mckergow, I Prosser, R Grayson, David Weaver, D Heiner
Journal articles
Riparian vegetation can trap sediment and nutrients derived from hillslopes. Most research into the effectiveness of riparian buffers has been experimental and little quantitative data exists on performance under natural field conditions. This study reports on grass and tree buffer performance under natural rainfall conditions in two contrasting Australian environments. Buffers receiving runoff from hillslopes cropped with bananas were monitored over a 4-year period in the wet topics of Far North Queensland (FNQ). Runoff, bedload and suspended loads were measured leaving the crop and leaving 15 m wide dense grass and remnant rainforest riparian buffers. The grass buffer was able …

Kellerberrin Townsite Test Pumping Results 2003, Louise Hopgood
Kellerberrin Townsite Test Pumping Results 2003, Louise Hopgood
Resource management technical reports
A production bore in Kellerberrin, Western Australia, was test pumped for 24 hours in August 2003. Data generated by the pumping were analysed with groundwater monitoring, climate and geological data. Laboratory analyses of water samples from the production bore indicate a low pH and very high levels of salinity, hardness, sodium, chloride, iron, sulphate, aluminium and manganese. This is likely to lead to scaling, blockages, staining and/or corrosion of pumps, pipes and pipe fittings.
