  • The viability of treated piggery wastewater for reuse in agricultural irrigation

    Background The swine production is a very important economic matter, occupying prominent position in the worldwide market. However, it appears as the greater impacting activity for the water resources. Researches point a swine manure production of 105.6 million m3/year in Brazil, which resulted in a piggery wastewater rich in solids, nutrients, heavy metals, and pathogens. Moreover, ...

  • USDA research study finds UVC lights improve quality, shelf life of cut Cantaloupe

    A research study conducted by the U.S. Department of Agriculture's Agricultural Research Service has found that high-output ultraviolet-C (UVC) lights are effective in improving the quality and shelf life of fresh-cut cantaloupe melon. The findings of the study, which used high-output UVC lights manufactured by Steril-Aire, Inc., have far-reaching implications because the $15 billion fresh-cut ...


  • How green was my Vertical Farm?

    By 2050, 80% of the earth’s population will live in cities and 3 billion more people will need to be fed. The simple fact is we are running out of available land to grow enough food to feed them. If we can’t grow our cities outward to find more arable land, the only solution is to grow them upwards. This may change the way we design cities forever.The problem is real and immediate. Even by most ...

  • 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 ...

  • What is it about this soil that protects plants from devastating disease?

    Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. ...

  • Development of a Bioaccumulation Model For Herbicides in Ulva and Clams

    Coastal lagoons are shallow water ecosystems characterised by high biodiversity and primary and secondary production, and with an elevated number of different habitats. These habitats have a key role as nursery and rest areas for a great number of marine species and birds. During the last decades these ecosystems have been exposed tomany anthropogenic pressures (urban, domestic, agricultural ...


  • Use of plant growth-promoting bacteria for biocontrol of plant diseases: Principles, mechanisms of action, and future prospects

    Pathogenic microorganisms affecting plant health are a major and chronic threat to food production and ecosystem stability worldwide. As agricultural production intensified over the past few decades, producers became more and more dependent on agrochemicals as a relatively reliable method of crop protection helping with economic stability of their operations. However, increasing use of chemical ...

  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • 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 ...
