Evaluation of a solid-liquid manure separation operation
… the efficacy and practicality of a solid-liquid separation barn for finishing pigs. The solid-liquid separation system included a mechanical scraper and gravity flow system to separate manure into solid and liquid portions. The objectives of this research were to evaluate the performance …

Effect of Liquid Manure on Corn and Soybean Growth, Nitrogen Uptake, and Yields
The injection of liquid manure into soils, at rates that should provide sufficient quantities of nitrogen (N), phosphorus (P), and potassium (K) for corn, has resulted in uneven growth and reduced grain yields. Field studies were conducted at Pearl City, Illinois, in 1983 and 1984 to evaluate the …

The Effects of Manure Handling and Dietary Protein on Ammonia Fluxes from a Flush Dairy
… fluxes to the atmosphere from each stage of manure handling at a flush dairy. The second objective was to examine the effect of manure handling itself on ammonia fluxes. We examined four different stages of manure handling: 1. Fresh mixture of urine and feces to represent what may be scraped …

Hydrogen Sulfide Emission and Control Parameters From Stored Liquid Swine Manure
… was observed to reduce H$\sb2$S production from liquid swine manure. Nitrates were quickly depleted in the first two days of manure storage. The presence of nitrate was observed to reduce H$\sb2$S concentration in the manure quite significantly. However, sulfides were not removed completely from …

Corn Production, Inorganic Nitrogen Distribution, and Soil Chemical Transformations Associated With Liquid Beef Manure Application Methods
… crop growth and production problems when liquid manure was knife injected into soil. Field and laboratory studies were conducted to determine the effects of liquid beef manure application methods and nitrification inhibitors on corn (Zea mays L.) yield, plant N concentrations, and soil …

Modeling nutrient requirements and measuring nutrient outputs of feedlot cattle
… generated interest in capturing value through manure in integrated crop and cattle feeding systems. The impact of facility design (Open lot, Pack, Stockpile, Pit, Lagoon), cattle type (Beef or Holstein), and dietary energy value (Grower or Finisher) on manure nutrient concentration was …

Nitrate and Ammonium Transformation and Fate in Groundwater of an Agricultural Watershed: An Isotope and Geochemistry Approach
… Observations from the agricultural site where liquid manure was the dominant fertilization method, suggest the chronic loading of NH4 in the subsurface. There is possibly less retention of NH 4 in soil water (> 20 ppm-N), resulting in the infiltration of NH 4 (2 ppm-N in piezometers), while NO3 …

Epidemiología molecular de Staphylococcus spp. desde un enfoque One Health: genes emergentes e inusuales de resistencia a antibióticos y de virulencia
… recovered from environmental samples (air and liquid manure tank) of two pig farms, with intensive production (IP) and semiextensive production (SEP), were analyzed. Four MRSA and MSSA (methicillin-susceptible S. aureus) isolates of lineage CC398 were recovered from the air of the PI farm. …
