  • 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 ...

  • Uses of winery and distillery effluents in agriculture: characterisation of nutrient and hazardous components

    ABSTRACTTwenty-one samples of winery and distillery effluents were collected from different Spanish winery and distillery industries. Electrical conductivity, pH, redox potential, density, organic charge (chemical oxygen demand, biological oxygen demand, total, volatile and suspended solids, oxidisable organic C and polyphenols) and contents of plant nutrients and heavy metals were analysed. The ...

  • Enhancing nutrient cycling by coupling cover crops with manure injection

    Coupling winter small grain cover crops (CC) with liquid manure injection may increase manure nutrient capture. The objectives of this research were to quantify manure injection effects using target swine (Sus scrofa) manure N rates of 112, 224, and 336 kg N ha–1 on CC plant density, fall and spring shoot biomass, N, P, and K uptake and subsequent corn (Zea mays L.) yield. A winter rye (Secale ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • Transport of lincomycin to surface and ground water from manure-amended cropland

    Livestock manure containing antimicrobials becomes a possible source of these compounds to surface and ground waters when applied to cropland as a nutrient source. The potential for transport of the veterinary antimicrobial lincomycin to surface waters via surface runoff and to leach to ground water was assessed by monitoring manure-amended soil, simulated rainfall runoff, snowmelt runoff, and ...

  • Design of an integrated piggery system with recycled water, biomass production and water purification by vermiculture, macrophyte ponds and constructed wetlands

    Since 2001 the swine experimental station of Guernévez has studied biological treatment plants for nutrient recovery and water recycling, suited to the fresh liquid manure coming out of flushing systems. An integrated system with continuous recycling was set up in 2007, associated with a piggery of 30 pregnant sows. It includes a screen, a vermifilter, and macrophyte ponds alternating with ...

  • Coffee`s new uses saves manufacturer big money - case study

    For over a decade Sustainable Resources Group (SRG) has provided this client with turnkey service providing beneficial re-use of residuals from the production of coffee and tea beverages. SRG manages the use of 43,000 tons of bulk residuals and another 7.3 million gallons of liquid residuals annually. Local land application of the plant’s wastewater treatment residuals as a liquid ...

  • 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 ...

  • 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 ...

  • Got Milk? Got Wastewater Too! Treatment of Dairy Processing Wastewater

    ABSTRACTA major dairy processing operation owned and operated by the Michigan Milk Producers Association (MMPA) located in central lower Michigan was required to design and construct a process wastewater treatment plant within a 14 month period. The system is sized to treat up to 0.5 MGD of dairy processing wastewater at a biochemical oxygen demand (BOD) concentration up to 1,846 mg/L. Effluent ...

  • 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 ...

  • Cow-pattie power

    On a massive cattle feedlot located outside the town of Vegreville, Alta., the pungent odour of cow manure is masked by the sweet smell of the province’s energy future. Turning cattle dung — “brown gold,” as some call it — into green power and other valuable byproducts is a made-in-Alberta energy solution that is not only sustainable and energy efficient, but also ...

  • 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 ...
