Spain: WELTEC BIOPOWER RNG Plant Cuts Carbon Emissions of Dairy Cattle Farm
Currently, German biogas specialist WELTEC BIOPOWER is building a biomethane plant for the Spanish dairy cattle farm Torre Santamaría. Since the first 250-kW biogas plant went live back in 2011, the Catalan family business has been able to cover its entire energy demand from its own residues. The farm in Vallfogona de Balaguer was the first milk producer in Spain to use any residual ...

AHDB develop soil health scorecard
The Agriculture and Horticulture Development Board (AHDB) have developed a way to quantify the health of your soil. In 2016, AHDB and BBRO funded the five-year Soil Biology and Soil Health Partnership. With its focus on soil health, one ambition was to produce a toolkit to assist with its measurement and management. One of the first tasks was to review what could be measured and how practical ...

PercoMeta Project, first step to industrialization
A representation of French companies visited the pilot plant of PercoMeta Project in Villavaquerín (Valladolid) during the month of June. This project led by Toro Equipment in collaboration with Cartif Technology Center and other enterprises from France tries to optimize the anaerobic digestion of cereal straw, reducing costs and increasing the quality of generated biogas. PercoMeta ...

How to Make Cow Dung Fertilizer
Currently, the most common and valuable processing method is to turn cow dung/manure into sellable organic fertilizer. Cow dung is a derived product from wastes produced by cattle, providing high levels of organic materials and rich in nutrients, including about nitrogen, phosphorous and potassium as well as many other essential nutrients. According to the data, daily cow dung contain 12.9% DM ...

From the ground up: local knowledge informing agri-environmental policy
Agricultural land use presents a number of environmental challenges, which the European Commission is committed to addressing through a range of agri-environmental policies. A new study points to the importance of aligning agri-environmental policies with farmers’ needs and operations. Using the case of land clearing in Finland, the research underlines the importance of incorporating input ...

Compost made by worms from livestock manure yields benefits when applied to maize
Vermicomposting livestock manure with maize can increase agricultural benefit by 304%, shows a new study. The combination of increased crop yield and the additional earthworms produced as a result of the process led to a substantial increase in output compared to a traditional composting system. As intensive agriculture and livestock production both increase, unique problems emerge. Heavy use of ...

New Material to Enhance Soils using Manure Waste
The results of the research group of Valuation of resources from Universidad Politécnica de Madrid suggest an optimal solution to manage the manure from chicken and cattle. Biochar, a material obtained after thermal treatment of this waste through pyrolysis, is an organic fertilizer that applied in soils and not only has positive effects on crop yields, but also represents a significant ...

Utilisation of nitrogen and phosphate on dairy farms could be increased
Nitrogen and phosphate are important fertilisers. But excessive amounts often found in fields and pastures end up polluting the ground and surface water. Furthermore, dairy farmers are squandering their profits by wasting these expensive fertilisers. The Koeien & Kansen [Cattle and Opportunities] project set up by two PhD candidates from Wageningen University, part of Wageningen UR, shows how ...

Beast of a weed creeping across Midwest from south
It's a beast of a weed, creeping north into the Midwest from cotton country. Palmer amaranth can shoot up as high as 7 feet, and just one plant can produce up to a million seeds. Herbicide is increasingly futile against it, and the weed's thick stems and deep roots make it hard work to clear by hand. It can slash yields and profits when it gets out of control. Midwestern weed scientists are ...

Effects of chemical fertiliser and animal manure on soil health compared
Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The complex ...

New strategy aims to reduce agricultural ammonia
As concerns about air pollution from large dairies and other concentrated animal feeding operations (CAFOs) continue to mount, scientists are reporting a practice that could cut emissions of an exceptionally abundant agricultural gas—ammonia—by up to 30%. In the May-June 2011 issue of the Journal of Environmental Quality, a team led by Mark Powell, a soil scientist with the USDA ...
