Since that time a process of organic conventionalization and bifurcation has occurred as traditional producers have entered the market and major firms have consolidated their organic positions. Conventionalization refers to the process by which organics take on similar characteristics of the mainstream agrifood system. Bifurcation refers to the process of organics dividing into large scale certified-organic operations selling in indirect markets and small-scale operations selling in direct markets based on trust. In this paper, we review the literature on conventionalization and bifurcation and contextualize it within the larger discussion on the sociology of agrifood.

Our job is finding solutions to agricultural problems that affect Americans every day, from field to table. Organic research is a vital and ongoing part of the overall ARS research portfolio and occurs at approximately 20 % of ARS research locations across the United States. The vision for ARS organic agriculture research is to help the organic industry overcome the challenges it faces related to productivity, profitability, environmental stewardship, and energy efficiency. ARS's organic research is an interdisciplinary research approach to understand the biological and physical processes innate to plants, soils, invertebrates, and microbes that naturally regulate pest problems and soil fertility so as to not rely on the use of synthetic pesticide and fertilizer production inputs. The agency's scientists are mainly seeking strategies to prevent the problems faced by organic growers and then, secondarily, looking for therapeutic controls that they can use. From a practical standpoint, this whole-system approach also describes a large part of ARS's research to improve conventional agriculture. Many of the results and lessons learned from conventional ARS research can be readily applied to organic farming systems, and vice versa. The objective of ARS organic agriculture research is to help producers compete effectively in the marketplace by producing abundant amounts of high-quality and safe products to meet consumer demands. A few illustrative examples of the types of organic research activities being performed by ARS scientists are presented below.</p><p>The challenge of integrating conservation tillage practices into organic production systems is a primary focus of the research at the Sustainable Agricultural Systems Laboratory (SASL) in Beltsville, MD, and is detailed in an accompanying article in these proceedings. SASL research seeks to address the challenges related to weeds and fertility in organic production. The research is focused primarily on organic grain production but includes practices that are applicable to vegetable production as well. A major SASL asset is a 17-year Farming Systems Project that compares two conventional and three organic grain crop rotations. Recent SASL research has led to the development of improved cover crops for increased fertility, improved soil conservation, and weed control. A scientist at the ARS National Soil Dynamics Laboratory in Auburn, AL, has been developing new and improved designs for roller-crimpers to manage and terminate cover crops while maintaining high residue cover. Numerous designs and prototypes have been developed and tested in varying cropping systems across the State of Alabama.

According to the current state of knowledge and development, how does organic agriculture contribute to each of these sustainability dimensions?</p><p>Sustainability has first been equated with environmental soundness in order to ensure the continued provision of goods and services to present and future generations. Organic agriculture, as defined by the Codex Alimentarius Commission, “is a holistic production management system that avoids use of synthetic fertilizers, pesticides and genetically-modified organisms, minimizes pollution of air, soil and water, and optimizes the health and productivity of interdependent communities of plants, animals and people.”</p><p>In organic agriculture, limiting external inputs necessitates adaptation to local conditions in order to harness ecosystem services and increase production efficiency. To this end, the main organic strategies include: rotations, diversification and integration of crop, livestock, tree, and fish to the extent possible in order to optimize nutrient cycling; use of local varieties and breeds in order to increase the system resilience to stress; use of biological pest control to enhance predators; and promotion of symbiotic nitrogen fixation and biomass recycling.</p><p>Organic management is associated with several positive impacts on land and water, including: increased soil fertility and thus, enhanced productivity; better soil structure that increases stability to environmental stress; better soil moisture retention and drainage, which result in 20 to 60% less irrigation requirements; less water pollution and nitrate leaching in groundwater; reduced erosion by wind, water, and overgrazing (currently, 10 million hectares of land is lost annually by unsustainable agricultural practices); and better soil carbon sequestration rates. A new meta-analysis indicates that soil organic carbon stocks were 3.5 metric tons per hectare higher in organic than in non-organic farming systems and that organic farming systems sequestered up to 450 kg more atmospheric carbon per hectare and year through CO<sub>2</sub> bound into soil organic matter.</p><p>Overall, energy use by organic farms may be reduced by one-third, as compared to conventional enterprises, due to more efficiency in biological nitrogen fixation. Existing studies report less energy use on organic farms, from 10-70% in Europe and 29-37% in the USA, with exceptions for some crops. The heart of the matter is that chemical agriculture uses 2 kcal of fossil fuel to produce 1 kcal of food energy. This low energy efficiency is compounded by higher oil prices that lead to higher farm input prices, in addition to peak oil, sooner or later. The energy issue requires more attention to paradigms such as organic agriculture in order to face future food challenges.</p><p>In line with the Intergovernmental Panel for Climate Change 4th Assessmen","PeriodicalId":100342,"journal":{"name":"Crop Management","volume":"12 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1094/CM-2013-0429-09-PS","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91569487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Between 2002, when USDA implemented national organic standards, and 2008, certified organic cropland acreage more than doubled in the United States, and certified pasture grew even faster.

However, most NIFA organic agriculture funding (Fig. 1) can be traced to the Organic Transitions Program (ORG), created by the 1998 farm bill and originally funded at $500,000 annually; and the Organic Agriculture Research and Extension Initiative (OREI), created by the 2002 farm bill and originally funded at $3 million yearly.

In 2009, funding for OREI increased to $18 million, followed by funding of almost $20 million from 2010 through 2012. ORG funding changed in 2010 to $5 million and then to $4 million in 2011 and 2012. IOWQP was only offered in 2009, but the environmental services focus continued in ORG and was removed from OREI in 2011 and 2012.</p><p>NIFA's investments in competitive programs are guided by priorities in the request for applications (RFAs) and awardees are selected through a rigorous peer review panel process based on relevance and scientific merit, among other factors. Only a small percentage of applicants receive NIFA awards: 26 to 47% and 8 to 16% for ORG and OREI respectively, from 2010 to 2012. Thus it is interesting to examine the extent to which the geographical distribution of these awards (Fig. 2) reflects the geographical distribution of the organic industry (<span>1</span>) (Fig. 3).</p><p>Most states have received at least one NIFA research award, but institutions in the Midwest, North Atlantic, and Pacific West regions (Fig. 2) have been the most successful. These three regions also led the US in organic sales in 2011 (<span>1</span>) (Fig. 3) with over $2 billion in sales in the Pacific West region, followed by over $519 million in sales in the Midwest region and over $340 million in sales in the North Atlantic region.</p><p>Similarly, the emphasis on fruits and vegetables in the distribution of awards to specific crop commodities (Fig. 4) reflects their importance to some extent. Markets for organic vegetables, fruits, and herbs have been developing for decades, and fresh produce was the top category in 2008 retail organic sales (<span>2</span>). From 1995 to 2008, certified organic fruit and nut production acreage rose from zero to 121,066 acres or 3.15% of total cropland (<span>2</span>). Organic carrots accounted for 13% of all US carrot acreage, the highest of any major commodity, followed by lettuce at 8% and apples at 5%. Although organic grain and oilseed crops represent only a small fraction of total US acreage: corn (0.2%), soybeans (0.2%), and wheat (0.7%) projects were funded to address a sh","PeriodicalId":100342,"journal":{"name":"Crop Management","volume":"12 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1094/CM-2013-0429-08-PS","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91884222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
