  • Value of composted organic wastes as an alternative to synthetic fertilizers for soil quality improvement and increased yield

    One of the major problems with agricultural soils in the tropical region of the western Pacific islands is their low organic matter content, which results from rapid decomposition due to the hot and humid environment. Composted organic material is frequently applied on agricultural fields as an amendment to provide nutrients and also to increase the organic matter content and to improve the ...

  • Nitrogen recovery from source-separated human urine using clinoptilolite and preliminary results of its use as fertilizer

    The use of source separated human urine as fertilizer is one of the major suggestions of the new sanitation concept ECOSAN. Urine is rich in nitrogen, phosphorus and potassium which act as plant nutrients, however its salinity is high for agricultural and landscape purposes. Moreover, characteristics change significantly throughout storage where salinity increases to higher values as the ...

  • 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 ...

  • Global Biofertilizers Market Analysis By Product (Nitrogen Fixation, Phosphate Solubilizing) is Expected to Reach USD 1,294.8 Million by 2020

    The global market for biofertilizers is expected to reach USD 1,294.8 million by 2020, according to a new study by Grand View Research, Inc. Increasing consumer adoption of organic foods is a key factor expected to boost the demand for biofertilizers. In addition, a favorable regulatory policy, especially in India and China, promoting sustainable agrochemicals, is expected to drive demand shift ...


  • A New Generation of GMOs

    Is synthetic biology on its way to our farms, markets and tables? Thousands of researchers will descend on Boston this fall for an event billed as the world’s largest gathering of synthetic biologists. The field is evolving so rapidly that even scientists working in it  ...

  • Long-term changes in Mollisol organic Carbon and Nitrogen

    Conversions of Mollisols from prairie to cropland and subsequent changes in crop production practices in the Midwestern USA have resulted in changes in soil organic matter. Few studies have used archived samples, long-term resampling of soils to a depth of 1 m, and space for time studies to document these changes. We resampled soils by depth (0–100 cm) in fields at 19 locations in central ...

  • High yielding organic crop management decreases plant-available but not recalcitrant soil phosphorus

    Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. Organic farming with low P inputs can result in deficient levels of plant-available phosphorus (available-P). The purpose of this study was to determine if common organically managed rotations are depleting P reserves or if large reserves still exist in unavailable forms. The research was ...

  • Seasonal ammonia losses from spray-irrigation with secondary-treated recycled water

    This work examines ammonia volatilization associated with agricultural irrigation employing recycled water. Effluent from a secondary wastewater treatment plant was applied using a center pivot irrigation system on a 12 ha agricultural site in Palmdale, California. Irrigation water was captured in shallow pans and ammonia concentrations were quantified in four seasonal events. The average ammonia ...

  • Biotechnology for Environmentally Safe Agriculture

    Issue: In Europe some uses of biotechnology are meeting vocal opposition from certain quarters. Nevertheless, the vast amount of knowledge acquired recently in biology can be used to develop and apply biotechnology for an environmentally safe agriculture. Public acceptance and a new policy impetus can serve to promote the introduction of safe and competitive agricultural technologies that have a ...

  • Organics in Action : Sustainable Practices Thrive In A National Park

    The Presidio is part of California’s Golden Gate National Recreation Area and the national park system. As an urban park on the northern edge of San Francisco, there are many challenges to be met in the quest to be a model of sustainability. An innovative composting program is becoming one way to help meet the park’s goals. Nearing the close of its second year, this program is well on its ...

  • Organic coffee production, shade coffee, quality coffee

    Organic coffee can be considered to be passive or active. Passive organic coffee production systems are systems that do not apply any form of chemical input. Active organic coffee production systems also do not apply chemical inputs but in addition they comply with a range of other criteria needed for organic certification. Organic certification is a necessary step if the coffee is to be exported ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...
