  • Composters Build Strong Links to California Farms

    The rapidly increasing amounts of compost applied to California farms can be traced to numerous factors — better crops, fewer disease problems, greater emphasis on product quality, mandated state recycling goals, savings in disposal costs and savings in chemical inputs. And then there’s the factor of friendship, longtime personal relationships that build trust between composters and farm ...

  • Agricultural Use of Different Residual Waste Composts - Current Situation and Experiences in France

    ABSTRACT Quality standards have been recently established in France for sewage sludge composts and other urban composts (greenwaste, biowaste and municipal solid waste composts). These standards allow to guarantee the innocuousness of the composts. Other standards have been defined in order to predict the compost effects on soil properties: the index of biological stability (ISB), based on ...

  • Antibiotics in groundwater under locations with high livestock density in Germany

    Antibiotics are deployed in large quantities both in human and in veterinary medicine. Studies show that antibiotic residues occur in the environment (e.g. soil and surface waters). In some cases they were also detected in ground and drinking water. However, the degree of groundwater pollution by antibiotic residues from livestock farming is unknown. Therefore, the federal environment agency ...

  • Nitrogen recommendations for corn: An on-the-go sensor compared with current recommendation methods

    Precision agriculture technologies provide the capability to spatially vary N fertilizer applied to corn (Zea mays L.), potentially improving N use efficiency. The focus of this study was to evaluate the potential of improving N recommendations based on crop canopy reflectance. Corn was grown at four field sites in each of 2 yr in Centre County, Pennsylvania. Preplant treatments included: zero ...

  • Evaluating slurry broadcasting and injection to ley for Phosphorus losses and fecal microorganisms in surface runoff

    The recent growth in the size of dairy cattle farms and the concentration of farms into smaller areas in Finland may increase local water pollution due to increased manure production and slurry application to grass. Therefore, a field study was conducted to monitor losses of total phosphorus (TP), dissolved reactive phosphorus (DRP), and fecal microorganisms in surface runoff from a perennial ...

  • Redefining ag-wastes as coproducts

    Alan Doering doesn’t have the word “waste” in his vocabulary. As the scientist heading up the Agricultural Utilization Research Institute’s (AURI) coproduct utilization program, Doering sees crop residue, agricultural processing leftovers and biomass as products with value worth exploring. “Every leftover or coproduct has a value,” Doering says. “Our goal is to find the best use with the highest ...

  • Pragmatic farm composters forge new path to resource recovery

    AG CHOICE is an on-farm composting operation located in the scenic countryside of Andover, New Jersey. On the drive to tour their site, it was astounding just how much of New Jersey, our most densely populated state, is still rural. Jay and Jill Fischer operate the two-year-old facility, which is one of a kind in New Jersey. Jay also owns and operates a sawmill in the area, and it was while ...

  • Critical source area management of agricultural phosphorus: experiences, challenges and opportunities

    The concept of critical source areas of phosphorus (P) loss produced by coinciding source and transport factors has been studied since the mid 1990s. It is widely recognized that identification of such areas has led to targeting of management strategies and conservation practices that more effectively mitigate P transfers from agricultural landscapes to surface waters. Such was the purpose of P ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • 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 ...

  • Effects of biowaste compost amendment on soil microbial biomass and specific carbon turnover in agricultural soils

    The importance of biowaste compost as organic fertilisers has become more emergent in the last years due to the increased production of compost produced from biowaste. The utilisation of organic fertilisers in agriculture improves the physical, chemical and microbial properties of soils (Allievi et al., 1993; Senesi, 1989). Amendment of compost affects several soil properties positively like e.g. ...

  • Ohio Takes Aim At Food Waste Composting

    WHILE RECYCLING of paper and yard trimmings have grown rapidly in Ohio in the last 30 years - now up to 50 percent for paper and 62 percent for green materials, the recovery rate for food residuals is at less than three percent of nearly 96 million tons generated annually. To turn things around, the Ohio EPA and its Solid Waste Management Division have teamed up to get the word out about ...
