If you have excess dairy manure or are providing manure to a neighboring farmer supplying you with forage, it's important to know a ballpark figure of what that manure is actually worth.
This fall has been exceptionally wet and that has led to saturated soil conditions around much of Iowa, and while this has made the primary focus on manure delayed harvest of corn and soybeans and thus limited area for manure application.
This spring started cool and wet, delaying planting season, but was followed by a beautiful early summer with warm temperatures and heat units that pushed crops forward quickly. As harvest season has neared, we have been faced with some wet conditions slowing harvest.

The opportunity to get bedded-pack cattle manure was too good to pass up. But now as the field in front of me is a sea of white with deep drifts, one question arises, "Where is the best location to temporarily store the manure?"
Recent heavy rains in southern Minnesota finds some livestock producers scrambling to stem overflow from livestock manure storage basins. Pollution problems include overflowing manure and wastewater storage structures and releases from underground and above-ground storage tanks as well as open feedlots located in floodplains or in sensitive areas where runoff can enter surface waters.
There is a great misconception within the global marketplace about the durability, service life cost and capacity capability of bolted steel tanks when compared to both sectional and pre-cast concrete tanks for applications within the water, wastewater, and anaerobic digestion market sectors.When correctly specified and produced, concrete can be an excellent construction material providing long service in many conditions, however, the quality and durability of a concrete tank is dependent on many factors that are often difficult to control.Consider the following:Pre-stressed concrete tanks: Bioenergy plants provide a severe environment for concrete. As these tanks enter the first, second and third decade of service, the effects of years of unprotected exposure are apparent with cracks, spalls, and leaks. The introduction of reinforcing steel created a problem affecting the durability of concrete. As rebar corrodes, concrete cracks and spalls reducing structural integrity AND allowing elements to enter into the concrete increasing the deterioration. Additionally, rust forming on rebar increases the volume (result = expansion) of the steel creating large tensile forces. Concrete cannot withstand tensile stress and it cracks to relieve the pressures. For more, CLICK HERE
There has been some success with using biocovers to reduce the odors and environment-damaging gas emissions from liquid manure lagoons – and a promising new cover material that has the potential to do even more is biochar.
October 30, 2017 – Are you at risk while pumping out your manure storage system? Without throwing out the “here’s your sign” card, the simple answer to the question posed is – yes! Many producers know and understand the risk associated with confined manure handling systems but accidents and deaths still occur because unwarranted risks are taken as manure is being handled and removed from the confined manure handling systems. Ask yourself these questions: Does every employee understand the risks associated with confined manure handling systems? Have they received proper training when dealing with confined manure handling systems? Do you have the appropriate hazard signage posted near the confined manure handling system, warning people of the dangers? Do you have the appropriate safety gear available and have you provided instruction to employees on using the equipment? Do you have employees with limited English speaking skills? Do they fully understand the safety risks and signage provided? Do employees and family members have the ability to communicate location directions in an emergency 911 call? These may seem like simple things, unfortunately they often go overlooked. We assume that everyone should know the risks and know what to do in an emergency. Taking the time to provide proper safety equipment, while simultaneously educating employees and family members about the correct safety protocols around confined manure handling systems helps prevent deaths and accidents. So what is the risk with confined manure handling systems? Understanding that there is risk associated with manure pits and manure lagoons is important. They both produce toxic gases as the manure undergoes anaerobic digestive fermentation. The gases produced and the characteristics of each are below: Methane – is an odorless gas that is flammable or explosive at concentrations of 5 to 15 percent by volume of air. The gas is lighter than air and typically found near the top of the pit and high enough concentrations can cause death by suffocation. Hydrogen sulfide – is an extremely toxic gas with a “rotten egg” smell at low concentrations and which at high concentrations can paralyze the olfactory senses. It is heavier than air and often settles towards the bottom of the manure pit. At low concentrations it can cause dizziness, headache, nausea, and respiratory tract irritation. At high concentrations it can cause unconsciousness, respiratory failure and death within minutes. It is also explosive at various concentrations. Carbon Dioxide (CO2) – is an odorless gas that is heavier than air and often settles near the bottom of the manure pit. At low concentrations it causes labored breathing, drowsiness and headaches. In high concentrations it can displace enough oxygen and cause death via suffocation. Ammonia (NH3) - has sharp odor characteristics that irritate the eyes, nose, throat and lungs. Exposure to high concentrations can be fatal. Besides understanding the various types of gases produced in confined manure handling systems, you should also follow these guidelines when working around confined manure handling systems. Manure Pits These are enclosed manure storage structures, which should be equipped with ventilation systems. They are often found in dairies as manure is pumped out to a lagoon or in confined swine operation buildings or certain types of beef finishing operations that utilize a confined building. Follow these safety guidelines around manure pits: Keep all manure pits ventilated and fans working properly. Keep all manure pits covered with appropriately ventilated grating. Post hazard signs near all manure pit entry point locations. Never enter a manure pit unless absolutely necessary and only when proper safeguards are utilized. If entry into the pit is necessary, test the air for toxic gases. Never enter a manure pit unless someone is standing by and maintaining constant contact. The person standing watch should be able to lift an unconscious person wearing a safety harness attached to a lifeline. They should NEVER enter the pit trying to rescue someone and have the ability to communicate necessary information in case of an emergency 911 call. Always wear a safety harness that attached to a mechanical device such as a winch, hoist or pulley. This is your lifeline, so the person on the outside must maintain constant contact with the lifeline. Always wear a positive-pressure, self-contained breathing apparatus (SCBA). Provide a powered, explosion proof air ventilation system for each manure pit that will help bring in a continuous fresh air supply. NEVER enter a manure pit to attempt a rescue without a safety harness and proper respiratory protection! Manure Lagoons They also produce toxic gases in localized layers, which, especially on hot, humid days with little breeze can cause a health hazard and potential death. Gases are readily released when lagoons are agitated to remove manure to be incorporated as fertilizer into the fields. They often have a thick liquid, floating crust, which can make swimming and buoyancy difficult if you were to slip or fall into the lagoon. Additional safety guidelines for manure lagoons are as follows: Open-air lagoons should be fenced off around the perimeter with locked access gates to keep unauthorized people or unwanted animals from accidentally entering them. Hazard signs posted at entry points warning of toxic gases and drowning dangers. Wear a safety harness attached to a lifeline with someone on the other end that can drag you out if it is necessary to enter the lagoon. Rescue equipment such as flotation devices and lifelines attached to every manure pump. Move slowly around manure lagoons as the ground can be uneven causing a person to trip and fall. Never work alone but all other unnecessary bystanders should stay away from access points or pump-out points. No horseplay allowed in these areas. No smoking or open flames allowed near agitation or pumping areas due to the explosive gases that may be present. If equipment breakdown occurs during agitation or pumping shut it down and remove it from the lagoon area before servicing. Follow the same 911 emergency call guidelines as manure pits, be able to describe the situation, number of victims, location and directions. Safety is not a choice, it is something that we need to practice on a daily basis in agriculture. Enclosed manure hold facilities are one of many areas in livestock operations that have inherent risks. However, by following these recommended safety guidelines and training all involved we can be safer and live to see another day with loved ones and family.
August 10, 2017 – Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. Timing is also a problem. Livestock produce manure 24/7 – even when it is impractical or unwise to move it to the field. Delivering manure to the field needs to be timed to nutrient needs, soil moisture levels, and temperature. How can farmers handle this timing issue, as well as other manure problems? In cities, sewers and water treatment facilities deal with human waste. On farms, manure storage lagoons can hold the manure until the time is ripe. This solves the timing and delivery problem – but what about odor and gas emissions? In addition to the inconvenience of odor, manure can release gases connected to air pollution and climate change. Methane, nitrous oxide, ammonia, and hydrogen sulfide are examples. Scientist Brian Dougherty and colleagues researched methods to reduce these negatives while potentially adding some positives: biochar covers. Biochar is plant matter, such as straw, woody debris, or corn stalks, that has been heated to high temperatures in a low- to no-oxygen environment. The result is a black, carbon-rich material similar to charcoal. Dougherty says biochar is like a sponge. “Biochar provides a structure with lots of empty pore space,” he says. “The outer surface may appear small but the interior surface area is absolutely massive. A few ounces of biochar can have an internal surface area the size of a football field. There is a lot of potential there for holding on to water and nutrients.” In addition to its hidden storage capacity, the surface of the biochar tends to have a chemical charge. This gives biochar the ability to attract and hold nitrogen, phosphorus, and potassium ions, metals, and other compounds. Biochar can also float (some types more than others). That attribute means it can trap gases at the water’s surface. Growing up on a dairy farm, Dougherty is no stranger to the challenges of manure storage. “Once I realized the properties of biochar, I thought it had good potential for a lagoon cover,” he says. Dougherty’s research studied two liquid dairy manures with differing nutrient levels. It also studied two types of biochars, made at different temperatures. Biochar is somewhat fickle, showcasing different properties when created at different temperatures. He also included pails of manure with a straw cover for comparison, and au natural with no cover as his control. The research found that the biochars picked up the most nutrients from the more concentrated manure with a higher nutrient content. “The biochar will take up whatever it can, so if there are more nutrients available the potential for nutrient uptake is greater,” Dougherty says. Nitrogen, phosphorus, and potassium are nutrients with the greatest economic value on a farm, but applying them in excess of what the crop can take up can lead to nutrient loss to the watershed. Dougherty also measured the ammonia at the top of each pail. Ammonia and sulfates are the main source of manure’s odor. The cooler-crafted biochar did best here, reducing ammonia by 72 to 80 percent. It also floated better. But because it floated better and tended to repel water, it was less effective at attracting and attaching to the nutrients than the warmer-crafted biochar. Biochar is currently more expensive to buy than straw, but Dougherty is undaunted. Biochar could have a good economic return: excess farm and forestry residue could be used to create the biochar on site. This process generates energy that could be used heat water and warm buildings during colder months. There is also potential for generating electricity, fuels, and other by-products using more sophisticated equipment. After its use in the lagoon, the biochar could be spread on fields as needed. Any excess could be sold as a high-value fertilizer product. And biochar has great environmental benefits. “Anything you can do to prevent gases from escaping the lagoon is a good thing,” Dougherty says. “Biochar applied to soils – particularly poorer quality soils – is very helpful. Making biochar can also help reduce atmospheric carbon dioxide levels. A portion of the carbon dioxide that was taken in during plant growth ends up as a very stable form of carbon in the soil. The overall picture has multiple benefits.” Dougherty’s research did not avoid the obvious. Would biochar or straw best improve the dairy air? Since the human nose knows, Dougherty recruited a panel of judges. The weather intervened, however, with freezing temperatures and rain affecting the odor intensity over the 12-week trial. Despite these challenges, three different biochars were shown to reduce odor from liquid dairy manure, whereas a straw cover was not effective. “Determining the best trade-off of biochar properties will be an important next step,” Dougherty says. “More research could find the right biochar production temperature, particle size, pH, and float properties. The potential is there.” This portion of the research still needs to be sniffed out. Read more about Dougherty’s biochar research in Journal of Environmental Quality.
