  • Facing complexity on agro-ecosystems: a new approach to farming system analysis

    Sustainability requires the redefinition of the terms of reference for agricultural activities, which must be based on the recognition of multi-functional land use and the complex role that agriculture plays in society. The ability to renegotiate new terms of reference for agriculture, in turn, requires new analytical tools for agriculture analysis to be able to embrace the 'complexity ...

  • On-farm assessment of the amount and timing of nitrogen fertilizer on ammonia volatilization

    Ammonia (NH3) volatilization is one of the main pathways through which applied N enters the environment undesirably. A seven site-year on-farm field experiment was performed for 3 yr at Ottawa, ON, and 2 yr at Guelph, ON, and Saint-Valentin, QC, Canada. Our objectives were to (i) quantify the flux and the amount of NH3 volatilization as affected by the rate and time of N fertilizer; (ii) assess ...

  • Residual influence of organic materials, crop residues, and biofertilizers on performance of succeeding mung bean in an organic rice-based cropping sy

    Background The present investigation was undertaken to assess the residual influence of organic materials and biofertilizers applied to rice and wheat on yield, nutrient status, and economics of succeeding mung bean in an organic cropping system. The field experiments were carried out on the research farm of IARI, New Delhi during crop cycles of 2006 to 2007 and 2007 to 2008 to study the effects ...

  • Long-term agronomic performance of organic and conventional field crops in the mid-atlantic region

    Despite increasing interest in organic grain crop production, there is inadequate information regarding the performance of organically-produced grain crops in the United States, especially in Coastal Plain soils of the mid-Atlantic region. We report on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and wheat (Triticum aestivum L.) yields at the USDA-ARS Beltsville Farming Systems Project ...

  • Long-term water quality trends after implementing best management practices in South Florida

    A mandatory best management practices (BMP) program was implemented in the Everglades Agricultural Area (EAA) farms basin-wide in 1995 as required by the Everglades Forever Act to reduce P loads in drainage water reaching the Everglades ecosystem. All farms in the EAA basin implement similar BMPs, and basin wide P load reductions have exceeded the 25% reduction required by law; however, ...

  • Evaluation of climate change impacts and adaptation strategies for maize cultivation in the Himalayan foothills of India

    This study evaluates the impacts of climate change on rainfed maize (Zea mays) yield and evaluates different agro-adaptation measures to counteract its negative impacts at Sikkim, a Himalayan state of India. Future climate scenarios for the 10 years centered on 2025, 2055 and 2085 were obtained by downscaling the outputs of the HadCM3 General Circulation Model (GCM) under for A2 and B2 ...

  • Impact of Agri-environment measures

    The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...

  • Bull Calves Need Care Too

    By far, most bull calves will never become a lasting benefit to a dairy herd, and as such may not always receive the same level of care that heifer calves do. Harmonizing your calf rearing programs will yield positive results for all calves and your bottom line. All calves require excellent care, especially in the first few days of life. Without adequate, timely colostrum and proper ...

  • Climate Smart Agriculture: Zambia’s Strategy to Reduce Emissions

    The agricultural sector is believed to be the backbone of the Zambian economy thereby alleviating problems associated with poverty and food security. The development of the sector is viewed as one sustainable way of economic growth and ‘Eradicating Extreme Poverty and Hunger’ which is goal number one of the Millennium Development Goals (UN, 2000). The sector contributes to the growth ...

  • 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 ...

  • Cheap chemicals entice caterpillar-eating wasps to crops

    It may be a win-win situation: treating seeds with commercially available growth promoters before planting could have the added benefit of attracting parasitic wasps that feed on caterpillar pests, suggests a study. The protective effect of these cheap, commercially available chemicals, known as ‘plant strengtheners’, can help protect young ...

  • 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, ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...
