Digesters Growing With RNG
October 29, 2018 | By Chris Clayton, DTN Ag Policy Editor |Methane digesters are the new growth wave in renewable energy for agriculture. The stick and the carrot are both at work here. As livestock operations work on ways to manage manure, the changing landscape of environmental regulations and legal challenges -- along with state and federal grants and energy credits -- are combining to start an uptick in methane digesters to produce renewable natural gas (RNG).
85% of dairy farms had insufficient soil fertility levels in 2017
October 29, 2018 | By Seán Cummins |Of the dairy farm soil samples (in Ireland) analyzed by Teagasc in 2017, just 15% had optimal soil fertility levels as indicated by soil pH, phosphorous (P) and potassium (K), delegates were told at the Soil Fertility Conference earlier this week. Fertiliser inputs represent a significant cost, but are necessary for driving high grass, milk and meat outputs.
Modern farming: How Ottawa Valley agriculture is evolving to grow and prosper
October 26, 2018 | By Christopher Guly |When the federal government wanted to launch a clean-technology program this year, it used an Ottawa Valley farm to showcase how bioproducts could help reduce greenhouse gas emissions and promote sustainability. The site of the launch was Terryland Farms Inc., a 1,000-acre dairy farm east of Ottawa in St-Eugène. Eleven years ago, Terryland became the first Ontario farm to sell electricity converted from cow manure to the grid, and has since expanded to generating more power — and additional income — from solar panels.
Manure is turned to water in possible solution to farm waste problem
October 25, 2018 | By Keith Micallef |A prototype plant which converts pig and cow manure into clean water could be key to solving the huge environmental problem of the disposal of some 300,000 tonnes of farmyard waste each year. Developed abroad, the plant was brought to Malta for testing. An on-site facility needed to treat manure generated on a farm could produce 60 per cent of the equivalent volume of waste into water. Moreover, part of the bi-product could be used as fertiliser and the rest as fuel for waste to energy plants. Note: A similar U.S. based technology is profiled in the Newtrient Technology Catalog:
