New Manure Sidedress Method Lowers Fertilizer Costs, Increases Yields
With corn needing nitrogen, and pigs and cattle producing a lot of it, anything that offers a better way to use their waste to fortify crops should intrigue farmers. Two agriculture experts at The Ohio State University have redesigned a metal tractor attachment so that it allows farmers to put manure on a field while crops are emerging. Applying manure to growing crops, which is not widely done ...

Using Liquid Manure to Fertilize Wheat? Consider Timing, Nitrogen Content
Liquid livestock manure can be a great option as a spring top-dress fertilizer for wheat fields if applied during the appropriate window of time and if it has the right amount of nitrogen, according to research conducted by the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. In a report published in the latest issue of the college’s Crop Observation ...

Agricultural ammonia emissions could be reduced without affecting crop yield
Ammonia released by nitrogen fertilisers in Spanish agriculture could be reduced by up to 82% with only a very minimal impact on crop yield, finds new research. This could be achieved by combining optimised management of manure with the use of non-urea synthetic fertilisers. Agriculture accounted for almost 94% of total European atmospheric emissions of ammonia in 2011. The main sources of these ...

Ag Attorney Sheds Light on Manure Handling, Application Regulations
Although the Lake Erie algae problems that contaminated Toledo’s water supply in early August have subsided, the crisis raised questions about animal manure application on farmland in Ohio and how it may have contributed to the problem. In response, Ohio State University Extension’s agricultural and resource law field specialist has written a summary of Ohio laws relating to ...

Cover Crops Capture Nutrients to the Benefit of Farmers and Water Quality
Many factors contribute to the excess phosphorous that stimulates algal systems in bodies of water such as Lake Erie. Sources of excess phosphorous include urban stormwater, factories, sewers, household wastes and lawn fertilizer, and in some areas runoff from fertilizers or manure applied to fields. Fortunately, many farmers are already doing their part to improve water. For example, cover ...

Land-applied contaminated manure another source of spread of Q fever
A spatial analysis of the Q fever outbreak of 2006-2010 has revealed that new research Q fever outbreaks are often linked with the land application of contaminated manure. Until now it was thought that the contamination came directly from goat farms and therefore it was mainly people living in the vicinity of goat farms who became ill. The research was carried out by Alterra, in cooperation with ...

Spreading the Word about a Successful Agitation Boat Field Demo
Puck Custom Enterprises, a Cornell pump distributor, showcased their agitation boats and direct injection technology at a farm in Merced, California last week. The demo days, designed to let dairymen and other interested parties see the power of the agitation boat and the benefits of applying the liquid manure to the field using a drag hose system, was held at a working dairy with a very solids ...

Nutrient Management Plans: A Study in Cause and Effect
It seems practical on the surface. Nutrient management plans (NMPs) should supply plants with ideal amounts of nutrients, minimize runoff, and maintain or even improve the soil condition. And the farmer behind the plan would work with a set of conservation practices designed to reduce harmful pollutants while still obtaining optimal crop yields. However, many U.S. Animal Feeding Operations ...

EPA issues compliance orders to seven concentrated animal feeding operations in Iowa, Kansas and Nebraska
EPA Region 7 announced today that it has issued administrative compliance orders to seven concentrated animal feeding operations (CAFOs) in Iowa, Kansas and Nebraska, directing those operations to correct a range of violations of the federal Clean Water Act. Region 7’s latest round of CAFO enforcement activity, aimed at encouraging producers’ compliance with the Clean Water Act and ...

American society of agronomy
Recycling manure is an important practice, especially for large livestock producers. Manure can be used as fertilizer to aid in crop production, aiding livestock producers that grow their own feed crops. While manure does provide a rich nutrient source for crops, it also can contribute to nutrient leaching and runoff. This can contaminate the surrounding ecosystem and lead to eutrophication of ...

Nitrogen recommendations based on crop reflectance
Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

Understanding phosphorus in soils is vital to proper management
Phosphorus is one of the key nutrients that can cause algal blooms and related water quality problems in lakes, rivers, and estuaries worldwide. Phosphorus entering waters originates from a variety of sources. Agricultural land receiving long term applications of organic by-products such as animal manure is one of the major contributors. Such soils often become enriched with P, leading to ...

NFU demands action over nitrate vulnerable zone (NVZ) proposals
Defra (the UK's Department for Environment, Food and Rural Affairs) must make substantial alterations to its proposals to change Nitrate Vulnerable Zones before any action is taken to implement them, the National Farmers' Union warns. The NFU has submitted a list of 45 recommendations for alterations as part of its submission on the proposals, which it estimates will cost farmers hundreds of ...
