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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
