  • Little creek hog manure slurry store treatment case study

    The Challenge: Significant build-up of solids on the bottom of the slurry store (approximately five feet) with an expectation of another foot of accumulation by the end of the season (fall 2006). The Objective of the treatment: Preventing the further accumulation of solids and reducing the existing level of sludge in the slurry store using the BactiDomus® Technology Bio4Swine® In 2006 the ...

  • Filter manure slurries directly before, after, or in place of anearobic digesters with a reverse osmosis VSEP membrane system, providing potable water for the animals and a concentrated nutrient feedstock for fertilizer.

    If constructed and managed properly, the age-old lagoon method of manure handling is a reliable method of storing and treating livestock waste. Lagoon storage followed by sprayfield application on local farms has proven to be a very symbiotic and effective method throughout the ages. However, the recent trend in the hog production and the cattle industry is towards larger centralized operations ...

  • Transport and fate of estrogenic hormones in slurry-treated soil monoliths

    Received for publication October 29, 2007. The naturally occurring hormones, such as 17-β-estradiol, 17-{alpha}-estradiol, and estrone, present in livestock manure may have detrimental environmental effects if released into surface waters. In areas where manure application is intensive, estrogens have been found in surface waters in concentrations known to affect the endocrine system of fish ...

  • Dietary forage impacts on dairy slurry nitrogen availability to corn

    Precise feeding of protein and mineral supplement can maintain high levels of milk production and reduce nutrient excretion in dairy manure and losses to the environment. No information is available on the impacts of feeding different silages to dairy cattle (Bos taurus) on manure N cycling in soils. Slurry from dairy cattle fed rations containing alfalfa (Medicago sativa L.; ALF), red clover ...

  • Enhancing soil infiltration reduces gaseous emissions and improves n uptake from applied dairy slurry

    Rapid infiltration of liquid manure into the soil reduces emissions of ammonia (NH3) into the atmosphere. This study was undertaken to assess the effects of two low-cost methods of assisting infiltration of applied dairy slurry on emissions of NH3, nitrous oxide (N2O), and on crop N uptake. The two methods were removing of solids by settling-decantation to make the manure less viscous and ...

  • Cover crop effects on the fate of N following soil application of swine manure

    Abstract  Cereal grain cover crops increase surface cover, anchor corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] residues, increase infiltration, reduce both rill and interrill erosion, scavenge excess nutrients from the soil, and are easily obtained and inexpensive compared to other cover crop options. The use of cereal grain cover crops in fields where manure application occurs ...

  • Linking Wisconsin dairy and grain farms via manure transfer for corn production

    One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...

  • Evaluating slurry broadcasting and injection to ley for Phosphorus losses and fecal microorganisms in surface runoff

    The recent growth in the size of dairy cattle farms and the concentration of farms into smaller areas in Finland may increase local water pollution due to increased manure production and slurry application to grass. Therefore, a field study was conducted to monitor losses of total phosphorus (TP), dissolved reactive phosphorus (DRP), and fecal microorganisms in surface runoff from a perennial ...

  • Using anion chromatography–pulsed amperometry to measure amino compounds in dairy manure-amended soils

    Amino acids and amino sugars comprise the bulk of soil N, so information on their chemical forms and cycling patterns should enable better understanding of soil N cycling. In this study of soil samples that had received animal manure, we evaluated the capabilities of a recently developed analysis for soil amino compounds (19 amino acids, two amino sugars) that consists of methanesulfonic acid ...

  • Rainfall-induced release of microbes from manure: model development, parameter estimation, and uncertainty evaluation on small plots

    A series of simulated rainfall-runoff experiments with applications of different manure types (cattle solid pats, poultry dry litter, swine slurry) was conducted across four seasons on a field containing 36 plots (0.75 × 2 m each), resulting in 144 rainfall-runoff events. Simulating time-varying release of Escherichia coli, enterococci, and fecal coliforms from manures applied at typical ...

  • Latest Progress in Anaerobic Digestion

    Compared to countries like Germany and Denmark, the United States and Canada have a long way to go in creating the fundamental policy incentives and regulatory mandates that will encourage market development for anaerobic digestion (AD). Someone recently asked me how many years it would take to deploy AD systems on farms in North America that are large enough to economically use them. Given ...

  • In-situ comparison of phosphorus losses between organic and inorganic fertilizers

    Phosphorus (P) is one of the limiting factors of eutrophication. P added to soil from fertilizer application could pose a threat to water quality. According to agricultural habits, swine manure (SM), oil cake (OC), biogas slurry (BS), commercial organic fertilizer (OF) and compound fertilizer (CF) were selected to compare their P losses on a slope-land under natural rainfall. The results showed ...

  • A small plant with great success - case study

    The farm-based biogas plant operated by the Wienken family in Augustenfeld (near Löningen) is the first plant of its size built by bwe. Originally, the farm's operator had planned to install a straw heating element. However, since the input materials are available on the farm itself in their entirety, the decision to implement a biogas plant designed by bwe was obvious. One decisive aspect ...

  • Florida Dairy Succeeds With AD System

    North Florida dairy with 6,100 mature cows and 5,500 replacements installed anaerobic digestion system that is yielding multiple benefits. Dairy farming in Florida has financial and logistical challenges, including hot, humid summers; high electrical costs; access to fresh water; odor; greenhouse emissions and sandy soil issues. Alliance Dairies in Trenton, Florida has found sustainable ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Redefining ag-wastes as coproducts

    Alan Doering doesn’t have the word “waste” in his vocabulary. As the scientist heading up the Agricultural Utilization Research Institute’s (AURI) coproduct utilization program, Doering sees crop residue, agricultural processing leftovers and biomass as products with value worth exploring. “Every leftover or coproduct has a value,” Doering says. “Our goal is to find the best use with the highest ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...
