  • Dietary cation–anion difference and tetany index of timothy forage fertilized with liquid swine manure

    Incidence of metabolic disorders increases when dairy cows (Bos taurus) are fed forages that have a high dietary cation-anion difference (DCAD) (>250 mmolc kg–1 dry matter, DM) or high grass tetany (GT) index (>2.2), both associated with high forage K concentration, often caused by applications of liquid swine manure (LSM). We determined how DCAD and GT index of timothy (Phleum pratense L.), ...

  • Evaluation of Phosphorus source coefficients as predictors of runoff Phosphorus concentrations

    Received for publication December 27, 2007. Many states have adopted a P site index (PSI) as a risk assessment tool to determine when P-based nutrient management is required for a given agricultural field. Some PSIs use a weighting factor, the phosphorus source coefficient (PSC), to account for differences in P solubility between organic P sources. Information relating to appropriate values of ...

  • Nutrient transport characteristics of livestock manure in a farmlan

    Background :Livestock excretions containing high concentration of nutrient, pig liquid fertilizer, and cattle manure were applied to agricultural land. The characteristics of nutrient transport were examined in surface runoff and groundwater by an artificial rainfall event at real scale field site. Also, the effects of the artificial rainfall event on the characteristics of residual soil after ...

  • Use of Lime Stabilized Biosolids for Turf Grass Production in the New Jersey Pinelands

    A 700 acre farm producing turf grass sod for residential and commercial uses has been utilizing liquid, lime stabilized biosolids as its primary source of plant macronutrients on approximately 380 acres since late 1995. The farm is located within the New Jersey Pinelands, a sensitive and unique ecosystem characterized by pine-oak forests, sandy soils and high quality ground and surface waters. ...

  • Removal of Phosphorus from livestock effluents

    Received for publication December 12, 2007. For removal of phosphorus (P) from swine liquid manure before land application, we developed a treatment process that produces low P effluents and a valuable P by-product with minimal chemical addition and ammonia losses. The new wastewater process included two sequential steps: (i) biological nitrification and (ii) increasing the pH of the nitrified ...

  • Is colloid-facilitated Phosphorus leaching triggered by Phosphorus accumulation in sandy soils?

    The leaching of colloidal phosphorus (Pcoll) contributes to P losses from agricultural soils. In an irrigation experiment with undisturbed soil columns, we investigated whether the accumulation of P in soils due to excess P additions enhances the leaching of colloids and Pcoll from sandy soils. Furthermore, we hypothesized that large concentrations of Pcoll occur at the onset of leaching events ...

  • Burn it no more!

    The other day I came across an old news article from 2008 about a Dutch energy plant that burns 485,000 tons of poultry litter each year, converting it into renewable electricity. Wow, I thought. That is an old-fashioned way of getting rid of poultry litter – they must be releasing some 14,550 tons nitrogen gas into the atmosphere. All this to produce 270,000 MWh of electricity, 890,000 MWh ...

  • Phosphorus And Compost Use Dynamics

    Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources. Phosphorus is one of the 16 essential plant nutrients, and is considered one of the three major plant nutrients (along with nitrogen and potassium). Phosphorus is not only important in root development, but ...

  • Corn cob characteristics in irrigated central great plains studies

    Escalating fossil fuel cost and concern over global climate change have accelerated interest in cellulosic feedstocks, such as corn (Zea mays L.) cobs, for liquid fuel production. Little information is available about this plant organ. We compiled and summarized available cob data from several recent field studies in the Central Great Plains. Data were collected from two locations in Colorado and ...

  • Zonejection: Conservation tillage manure nutrient delivery system

    Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

  • Lowara pumps drive livestock operations

    Animal output processed for safe disposal, reuse and renewable energy Xylem scope Xylem Lowara have installed several different types of pumps in this process cycle. Ranging from the DLV submersible pump fitted with Vortex impeller used in the pressurization of wastewater obtained from the separation of the digestate. Various high efficiency e-range pumps ...

  • Phosphorus distribution in untreated and composted solid fractions from slurry separation

    Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

  • 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 ...

  • Adding Value To On-Farm Digesters

    ANAEROBIC digestion of dairy manure and food processing residuals in Michigan is not a new undertaking. Over the years, 11 farm digesters were constructed in the state, of which four are still operational, reports Michelle Crook of the Michigan Department of Agriculture in a presentation in the spring of 2007. “Three of the operating digesters are for livestock manure and one is for food ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Unlocking the potential of poultry manure

    The poultry industry is one of the largest and fastest-growing agro-based industries in the world. At the same time, the growth brings along a number of environmental problems. One of the major environmental problems is the accumulation of large amounts of wastes, e.g. manure. In order to mitigate these problems new economically sustainable technologies are needed. Manure has often been ...
