Fenceline Feeder Systems for Beef Cattle Production and Resource Conservation
11/21/2017 (new)

One of the most challenging and costly aspects of beef cattle production in Kentucky is winter-feeding. Many producers complain about the time required to feed stored forages, the mud, the drudgery that it creates for the operator, and the decline in production. The intense traffic associated with winter-feeding on unimproved surfaces causes mud, compaction, erosion, and loss of desirable vegetation, often resulting in annual pasture renovations to address areas impacted by winter-feeding practices. Fenceline feeding systems offer an alternative to traditional in-field bale feeding during the wet winter conditions that Kentucky often experiences. These structures can be utilized to reduce the impact of winter-feeding on pastures and improve the operational efficiency of a winter-feeding area. | AEN-134

Rainwater Harvesting for Livestock Production Systems
11/7/2017 (new)

Abundant, clean drinking water is an essential nutrient for livestock. The obvious water source that is recommended by veterinarians is city water. However, city water has its drawbacks. City water distribution systems are often expensive to install and have a recurring usage charge. In some instances, city water is unavailable, may have inadequate pressure, or producers consider it too expensive to operate, forcing them to use streams and ponds to water livestock. Collecting rainwater from a catchment area, is a low cost, high quality alternative water source that can supplement traditional water distribution systems and improve the environmental quality of farming operations. Rainwater harvesting involves the collection of rainfall from rooftops or land based catchments systems for storage and distribution as needed. Capturing rainfall has the added benefit of improving water quality by reducing soil erosion and runoff. Strategically installed rainwater harvesting systems can be used to direct stormwater around sensitive areas of the farm where animal waste is present, thus reducing the potential for nutrient and pathogen delivery to nearby waterways. Rainwater harvesting and stormwater management techniques can also reduce the volume of water that must be managed in liquid manure management systems by diverting clean water away from manure pits and lagoons. | AEN-135

Appropriate All-Weather Surfaces for Livestock
10/16/2017 (minor revision)

Many livestock producers would say that mud is a natural part of livestock production. But the creation of mud costs producers money and makes them less competitive. Livestock that walk through mud require more feed for energy but actually eat less because walking in mud requires more effort to get to feed and water. Therefore, mud decreases average daily gains. Mud accumulation on the coat increases the amount of energy needed to generate heat in the winter or to keep cool in the summer. Also, it can lower sale prices due to hanging tags. The creation of mud also increases animal stress and leads to a variety of health problems, including protozoan and bacterial infections. It is essential that livestock producers understand that mud hinders cost-efficient livestock production and efforts should be made to limit the creation of mud. This publication explains how mud is created and describes different types of hardened surfaces and pads that agricultural producers should use to reduce mud creation and ultimately increase production efficiency and protect natural resources. | AEN-115

Tire Tanks for Watering Livestock
8/8/2017 (new)

Kentucky's abundant forage and extensive stream system have helped the Commonwealth become the largest beef producing state east of the Mississippi River. While streams and ponds serve as a water source for many operations, livestock can quickly degrade soil and water quality by trampling streambanks and defecating and urinating in and around waterbodies. These actions increase sediment, pathogen, and nutrient loads to streams, rivers, and lakes which in turn can causes eutrophication. To help protect the health of Kentucky's soil and water, producers can implement best management practices (BMPs). These practices help reduce the sources of pollutants and/or the transport of pollutants to waterways. One such practice or BMP is limiting cattle access to streams and ponds. When producers exclude livestock access to stream and ponds and their associated riparian buffers, an alternative source of water is required. Automatic water fountains are one commonly used means of providing cattle with water from an alternate source. A water tank constructed using a heavy equipment tire may serve as a viable option for supplying livestock with an alternate source of water. | AEN-133

Modeling Best Management Practices
10/20/2016 (new)

Understanding the effectiveness of BMPs based on their location in the watershed and in relation to different types of pollutants is an important part of protecting waterbodies. One way to do this is with the use of models. | AEN-132

Farmstead Planning: Old Farm Buildings Repurposed for Better Farming: How to Develop a Complex
6/6/2016 (new)

The traditional farmstead planning process might have been ideal for farming operations set up on blank slate farms that were surveyed based on 640-acre sections. However, these concepts are more challenging for irregular shaped farms in Kentucky with existing structures built more than a half century ago. Older farm buildings may be underutilized because they were constructed using what would be considered obsolete technologies today. It is essential that producers take the time and obtain the necessary help to develop their farming operation plan in order to realize their potential and achieve their goals. | AEN-131

Drought Risk Management for Beef Cattle Farms
2/25/2016 (new)

Once a drought occurs, it can be difficult to effectively manage your resources and overcome the conditions that drought creates. At the heart of effective drought management is preparedness. A systems-management approach is an ideal tool for drought preparedness, as its goal is to improve each component of the farming operation (soils, forages, facilities, stock, etc.) and improve the connections between the components (i.e. the system). The goal of this publication is to aid beef producers in implementing best management practices (BMPs) that take a systems approach to maximizing farm water use efficiency, while operating under the assumption that water is becoming an increasingly uncertain resource that is vital to the future of the farm. | AEN-130

Measuring Discharge in Wadeable Streams
2/9/2016 (new)

Knowing the amount of water flowing in a stream can improve management practices such as those related to streambank erosion, pollutant loading and transport, and flood control. Streamflow or discharge is defined as the volume of water moving past a specific point in a stream for a fixed period of time. | AEN-129

Sediment Fingerprinting
2/9/2016 (new)

Sediments in waterbodies cause a number of problems such as harming aquatic habitats, filling reservoirs, and worsening flooding. High amounts of sediment in the water inhibit the ability of fish and aquatic macroinvertebrates to move, breathe, hunt and reproduce. Accumulated sediments in reservoirs reduces their useful life and increases costs associated with maintenance. Streams experiencing such sediment buildup carry less water during storm events. | AEN-128

Hydrologic Modeling
2/9/2016 (new)

Increased levels of urbanization result in reductions in the amount of rainfall that infiltrates and evapotranspires and increases the amount of rainfall that becomes runoff. These changes can result in flooding, streambank erosion, and water quality degradation. Hydrologic models are useful in understanding watersheds and how changes in a watershed can affect hydrology. Hydrologic models can predict the amount of rainfall that becomes runoff under different scenarios. | AEN-127

Common Hazards in Karst Terrain
11/11/2014 (new)

Karst refers to terrain largely drained by subsurface conduits and caves. Karst landscapes are characterized by surface features such as springs, sinkholes, shallow depressions, and rolling hills. Karst regions are also known for their subsurface or below-ground features such as conduits and caves. What makes a karst region unique is the way runoff drains from the land. In karst regions, some of the runoff flows into surface features such as sinkholes where it then travels underground. Some of this infiltrated water re-emerges at springs, and some continues moving underground. | AEN-126

Closing a Liquid Manure Storage Structure
8/11/2014 (new)

Liquid manure storage structures, such as a lagoon, holding pond, or pit, serve an essential purpose on an active livestock operation. However, when this structure is no longer actively managed it can become a major liability to the producer because of its potential to have a discharge. The discharge from a liquid manure storage structure can contain pollutants such as nutrients, heavy metals, hormones, pathogens, and agriculture chemicals, all of which can pose serious threats to human health and aquatic ecosystems. Because of the pollution potential, livestock producers ceasing their operation are required to close their liquid manure storage structure(s) as part of their Kentucky No Discharge Operational Permit. To help offset the costs of closing the structure, producers may want to apply for cost share funds through the Division of Conservation. Before beginning to close a liquid manure structure, the Kentucky Division of Water (KDOW) must be provided with a closure plan. This publication outlines the preferred practices and steps for closing a liquid manure structure to meet the guidelines of the KDOW. | AEN-125

Streambank Erosion
7/23/2014 (new)

Streambank erosion refers to the removal of soil and other material, such as rock and vegetation, from the streambank. Streambank erosion is a naturally occurring process, but the rate at which it occurs is often increased by anthropogenic or human activities such as urbanization and agriculture. Changes in land use can cause streambanks to erode at rates much faster than those seen in natural, undisturbed systems. | AEN-124

Lowering Somatic Cell Counts with Best Management Practices
5/14/2014 (new)

As health and food safety concerns grow, dairy producers are facing more stringent regulations. In 2010, the European Union (EU) set the somatic cell count (SCC) upper limit, an indicator of milk quality, for exported milk at 400,000 cells per milliliter. However, the current U.S. SCC limit is 750,000 cells per milliliter. As of January 2012, any U.S. milk used in export markets must meet the EU standards. It is projected that US milk processors will gradually adopt the EU upper limit, making it difficult for dairy producers to sell milk containing more than 400,000 somatic cells per milliliter. Dairy producers will have to find innovative and cost-effective ways to reduce the somatic cell count of their milk. This publication will discuss how agriculture best management practices can be used to lower SCC. | AEN-123

Groundwater Quality
1/6/2014 (new)

Groundwater is an important water source for activities such as drinking, bathing, cooking, and crop irrigation. Keeping our groundwater sources clean is becoming more challenging with an ever growing population. In watersheds underlain with karst, such as many of those in Kentucky, the groundwater is more susceptible to contamination. This is because surface waters, such as runoff and in some cases streamflow, travel into the subsurface of karst by way of fractures, sinkholes, swallow holes, conduits and caves Such direct paths into the groundwater mean that pollutants reach the aquifer much more quickly with little to no filtration. Thus, while waters from springs and wells may look clean, they may actually contain unsafe levels of pollutants such as bacteria and nitrogen. | AEN-120

Keeping Trash Out of Streams
11/14/2013 (new)

Fresh water is an essential natural resource that is used every day for drinking, bathing, cooking, cleaning, and recreation. In Kentucky, the water used for these tasks mainly comes from streams and rivers, but it can also come from groundwater. Because our streams, rivers, and aquifers are so vital to our daily lives, it is important that we protect them from trash, debris, and other pollutants found in stormwater. What happens to the land around these water sources affects their condition and health. | AEN-119

Managing Stormwater Using Low Impact Development (LID) Techniques
8/21/2013 (new)

As more land is covered by impervious surfaces, less rainfall infiltrates into the ground and instead becomes runoff. Too much runoff is problematic. Flooding increases, streambanks erode, and water quality is reduced. An increase of impervious area of as little 10 percent has been shown to negatively impact streams. The purpose of this publication is to explain low impact development strategies and how they can be used to improve stormwater management by reducing impacts on streams. | AEN-118

Modifying a Bale Unroller for Mulching between Plastic-covered Beds
4/25/2013 (new)

Round bales of hay or straw can be used to mulch between rows of plastic film mulch used in vegetable production. This practice may be particularly useful for organic production where herbicide use is prohibited. To make the job of unrolling round bales between rows of plastic easier, a commercially available three-point hitch mounted bale unroller was modified by extending the toolbar and adding a second mast so that the bale is offset, allowing the tractor to straddle a row of plastic while unrolling the bale between the rows. | AEN-117

Algae-Based CO2 Mitigation for Coal-Fired Power Plants
1/22/2013 (new)

As the world's population swells and the needs of developing countries increase, the world's overall energy usage also continues to rise. Recent international legislation emphasizes the effects of climate change and the crucial need to find a way to decrease the greenhouse gas (GHG) emissions being released into the environment. Consequently, power plants have an increased urgency to find a viable way to decrease their GHG emissions. This issue has prominent implications for Kentucky due to our economy's dependence upon coal production. | AEN-116

Using Weep Berms to Improve Water Quality
11/9/2012 (new)

Non-point source pollution (NPS) occurs when rainfall and snowmelt flows over the ground, picking up pollutants such as pathogens, sediments, and nutrients on its way to streams, rivers, lakes, and other bodies of water. More than 50 percent of the nation's rivers and streams and nearly 70 percent of the nation's lakes are impacted by NPS. Pathogens, sediments, and nutrients are the biggest contributors to impairment of rivers and streams while mercury, nutrients, and PCBs (polychlorinated biphenyls) are the biggest contributors to the impairment of lakes. One method of managing NPS pollution is through the use of structural best management practices (BMPs). Structural BMPs are designed to decrease the volume of runoff that enters water bodies by increasing infiltration rates. Examples of structural BMPs include rain gardens, stormwater wetlands, and riparian buffers. A newer structural BMP is a weep berm. | AEN-114

Nutrient Management Concepts for Livestock Producers
3/27/2012 (new)

Nutrients are constantly cycling through farms. Nutrients come onto a farm in the form of feed, commercial fertilizers, manure, or compost, and they leave the farm with harvested crops, sold livestock, and off-site disposal of manure and other waste. Sometimes nutrients are even lost to the air, soil, or water. Nutrient management allows farmers to use nutrients (specifically nitrogen, phosphorus, and potassium) wisely for optimal economic benefit with minimal impact on the environment. | AEN-113

Sinkhole Management for Agricultural Producers
10/18/2011 (new)

A karst landscape develops when the limestone or dolostone bedrock underneath the soil dissolves and/or collapses due to weathering. A karst system can be recognized by surface features such as depressions, sinkholes, sinking streams, and caves. In karst systems, surface water and groundwater are interconnected: surface water runoff flows into sinkholes and sinking streams and recharges the groundwater; likewise, springs maintain stream flow in the dry season. Kentuckians living in karst areas need to be acutely aware that any pollutants that reach either surface water or any karst feature can pollute the entire groundwater system (also called an aquifer). In addition, the cave system that accompanies a karst aquifer can allow pollutants to contaminate miles of water resources in just a few hours. | AEN-109

Paved Feeding Areas and the Kentucky Agriculture Water Quality Plan
7/28/2011 (new)

Kentucky's abundant forage makes it well suited for grazing livestock. Livestock producers can make additional profits by adding a few pounds before marketing calves; however, adding those pounds requires keeping calves during the winter months, when pasture forages are dormant and supplemental feed is required. The areas used to winter calves need to be conducive to feeding and need to avoid negatively impacting the environment, especially water quality. | AEN-107

Stormwater BMPs for Confined Livestock Facilities
7/28/2011 (new)

The U.S. Environmental Protection Agency states that agricultural sediment, pathogens, and nutrients account for more than 50 percent of water pollution in the United States. Animal confinement facilities, widely used for holding, feeding, and handling animals, are potential sources of that pollution. The pollution load of these facilities can be reduced by installing and maintaining best management practices. The BMPs may be implemented as part of permit compliance or may be used to ensure that a permit is not needed. | AEN-103

Permeable Pavement for Stormwater Management
7/26/2011 (new)

Managing runoff in urban areas offers many challenges for engineers, landscape architects, and planners. As cities grow, the amount of impermeable surfaces--those that do not allow water to infiltrate into the ground--increases. Examples of impervious surfaces are asphalt roads, concrete sidewalks, parking lots, building roofs, and areas of highly compacted soils such as in subdivisions. If not properly managed, the stormwater runoff produced by these impermeable surfaces can have negative effects on nearby surface waters. | AEN-108
web only | 7 pages | 4,028 words | 45 downloads | PDF: 720 kb


Reducing Stormwater Pollution
7/15/2011 (new)

Stormwater is excess water from rainfall and snowmelts that flows over the ground and does not infiltrate the soil. It is a concern not just in urban areas but in suburban and agricultural locations as well. As stormwater runoff flows over the land or impervious surfaces, it picks up and transports trash and debris as well as pollutants such as pathogens, nutrients, sediments, heavy metals, and chemicals. This publication reviews some of these techniques and provides a list of recommended resources for additional information. | AEN-106

Pasture Feeding, Streamside Grazing, and the Kentucky Agriculture Water Quality Plan
7/13/2011 (new)

Kentucky's abundant forage makes it well suited for grazing livestock, but the pasturing and pasture feeding of livestock need to be managed. Allowing cattle to behave as they would naturally can lead to overgrazing, congregation in sensitive areas, buildup of mud, loss of vegetation, compaction of soils, and erosion. | AEN-105

Building a Grade Stabilization Structure to Control Erosion
6/15/2011 (new)

Gully erosion creates large eroded channels that become problematic for many farms. Gullies form in natural drainage swales when vegetation in the swale is lost through overgrazing or tillage practices. They cause valuable soil to erode, and they form large channels that drain runoff into streams. This runoff can carry sediment, nutrients, and pathogens that can degrade the water quality. | AEN-100
