  • Nitrogen mass balance of a tile-drained agricultural watershed in East-Central Illinois

    Received for publication September 10, 2008. Simple nitrogen (N) input/output balance calculations in agricultural systems are used to evaluate performance of nutrient management; however, they generally rely on extensive assumptions that do not consider leaching, denitrification, or annual depletion of soil N. We constructed a relatively complete N mass balance for the Big Ditch watershed, an ...

  • The localization of agriculture

    In the United States, there has been a surge of interest in eating fresh local foods, corresponding with mounting concerns about the climate effects of consuming food from distant places and about the obesity and other health problems associated with junk food diets. This is reflected in the rise in urban gardening, school gardening, and farmers’ markets. With the fast-growing local foods ...

  • Assessing Environmental Integration in EU Agriculture

    Farming has a strong impact on the environment in the European Union (EU), both in a negative and a positive sense. The common agricultural policy (CAP) is a major driver of the agricultural sector, and can therefore positively influence environmental management by farmers. This briefing investigates whether relevant policy measures are well-targeted from a biodiversity perspective. It ...

  • Synthetic nitrogen fertilizers deplete soil nitrogen: a global dilemma for sustainable cereal production

    Received for publication December 19, 2008. Cereal production that now sustains a world population of more than 6.5 billion has tripled during the past 40 yr, concurrent with an increase from 12 to 104 Tg yr–1 of synthetic N applied largely in ammoniacal fertilizers. These fertilizers have been managed as a cost-effective form of insurance against low yields, without regard to the inherent effect ...

  • A dynamic analysis of nonpoint pollution control instruments in agriculture

    Nonpoint pollution from agriculture is an emerging issue in the environmental policy of the European Union. Dynamic optimisation techniques are important in nonpoint pollution, and neglect of dynamic aspects may seriously mislead the proper design of policy measures. This paper presents an empirical assessment of nitrogen pollution abatement in the Ebro basin of northeastern Spain. The aim is to ...

    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, ...

  • Agriculture and Environment in EU-15 — the IRENA Indicator Report

    Background and purpose The IRENA operation (Indicator Reporting on the Integration of Environmental Concerns into Agriculture Policy) is a joint exercise between several Commission directorates-generals (DG Agriculture and Rural Development, DG Environment, Eurostat and DG Joint Research Centre, and the European Environment Agency (EEA) to develop agri-environmental indicators for monitoring the ...

  • Self-purification process and retention of nitrogen in floodplains of River Nemunas

    Due to its catchment size and its significant level of agricultural pollution, the Nemunas river basin has been identified as an agricultural hot spot in the Baltic Sea basin. On average, the total annual inorganic nitrogen runoff into the river is 26.9 × 106 kg, which corresponds to a load of 275 kg km−2 yr−1. A submerged floodplain, covering 605 km2 of the River Nemunas lowland, maintains the ...

  • Considerations on the importance of nutrition habits for the national nitrogen balance of Austria

    The anthropogenic nitrogen turnover of Western societies is highly unbalanced. As a consequence, a permanent supply of nitrogen via mineral fertiliser (produced with high energy inputs) and/or imported fodder are required and result in significant impacts of nitrogen emissions on the environment (air, water, soil). Key factors to an improved nitrogen balance on a national scale are the nutrition ...
