Item Residential sewage lagoon systems: a homeowner’s guide to installation and maintenance(University of Missouri--Columbia, Extension Division, 2022) Schultheis, Robert A."Residential waste stabilization lagoons are commonly used for onsite sewage treatment in Missouri in low-population areas where soils are not suited for conventional absorption field systems. An estimated 30 percent of all housing units in Missouri use onsite wastewater treatment systems. Several surveys throughout the state have shown that 70 percent, or 150,000, of these systems are not functioning properly. Counties in the Missouri Ozarks are particularly at risk. Human contact with sewage is a serious public health risk. Drinking water contaminated with sewage can cause health problems such as diarrhea, nausea, cramps, dysentery and hepatitis. Exposure to sewer gases can also cause discomfort and illness."--Page 1.Item Benefits and risks of biosolids(University of Missouri. Extension Division, 2022) Brune, David; Arnold, Ken; Magai, Robert; Hoormann, Richard; Miles, Randall"Biosolids are domestic wastewater sludge that meet standards for beneficial use as fertilizer or soil conditioner. The U.S. Environmental Protection Agency (EPA) and the Missouri Department of Natural Resources (Missouri DNR) developed standards to regulate safe use or disposal of biosolids. The standards were specifically developed to protect human health and the environment, including the health of animals, crops, soils, wildlife and aquatic life."--Page 1.Item Best management practices for biosolids land application(University of Missouri. Extension Division, 2022) Brune, David; Arnold, Ken; Dunn, John; Carpenter, Jerry D."Biosolids is domestic wastewater sludge that meets standards for use as a fertilizer or soil conditioner. These standards include monitoring requirements, metal limitations, pathogen reduction, vector requirements and best management practices. Applying biosolids to land uses the available nitrogen, phosphorus and potash as fertilizer for growing crops. It is an environmentally sound practice sanctioned by the U.S. Environmental Protection Agency (EPA)and the Missouri Department of Natural Resources (DNR). Reusing biosolids on crops, pastures and timberland reduces water pollution. It eliminates the environmental risks and costs associated with sludge disposal options, benefiting all Missourians."--Page 1.Item Fertilizer nutrients in dairy manure(University of Missouri. Extension Division, 2022) Brune, David; Fulhage, Charles D.; Pfost, Donald L."Many dairy producers fall into one of two categories: (1) They are willing to make high capital and labor outlays to maximize the usage of their dairy wastes for crop production (2) They are willing to minimize the amount of nutrients returned to the land for crop production in exchange for a relatively low-cost and low-labor method of waste disposal. Producers in the first category usually use slurry systems with tanks for waste storage, and tank wagons with injectors to transport and apply the waste. Producers in the second category use lagoons for storage/treatment, and irrigation equipment to transport and apply the waste to their fields. To have value, wastes must be used in a manner that results in a salable product. This publication describes methods of recovering a portion of the plant nutrient value of dairy wastes."--Page 1.Item Nitrogen in the environment: essential plant nutrients(University of Missouri. Extension Division, 2022) Brune, David; Killpack, Scott C.; Buchholz, Daryl"Carbon, oxygen and hydrogen are among the most basic elements necessary for plant growth. Plants obtain these elements from water and carbon dioxide in the air and soil. Plants also require additional 'mineral elements' that they obtain from the soil for proper growth and development. These mineral elements, together with carbon, hydrogen and oxygen, are referred to as essential plant elements or nutrients. They are essential because they are important to plant functions. Plants would not be able to grow, develop and reproduce without them. Although all are not necessarily essential to all plants, all are essential to some."--Page 1.
