Crops for Certified Organic Pepper Production
Introduction Organic production rose to 2.3 million acres in the U.S. in 2001 (USDA-ERS, 2002). Much of the increase has been associated with the implementation of consistent federal standards for products marketed as “organic” in October 2002 (USDA/AMS, 2002). In order to meet certified organic requirements in the state of Iowa (IDALS, 2000), a soilbuilding cover crop is required for at least ...
متن کاملEvaluation of Soil Amendments and Cover Crops for Certified Organic Pepper Production
Introduction With the implementation of consistent federal standards for products marketed as “organic” in October 2002 (USDA/AMS, 2002), organic production and consumption is expected to increase beyond current organic sales of $10 billion in 2001 (OTA, 2002). In 1999, Iowa farmers reported 150,000 acres of organic production to the Iowa Department of Agriculture and Land Stewardship survey (I...
متن کاملCover Crops and Fertilization Alter Nitrogen Loss in Organic and Conventional Conservation Agriculture Systems
Agroecosystem nitrogen (N) loss produces greenhouse gases, induces eutrophication, and is costly for farmers; therefore, conservation agricultural management practices aimed at reducing N loss are increasingly adopted. However, the ecosystem consequences of these practices have not been well-studied. We quantified N loss via leaching, NH3 volatilization, N2O emissions, and N retention in plant ...
متن کاملCover Crops as an Agroecological Practice on Organic Vegetable Farms in Wisconsin, USA
Global agricultural and food systems face the challenge of feeding a growing world population in the face of finite and diminishing resources. To guide the redesign of agricultural systems, farmers and policymakers are increasingly turning to agroecology. Organic agriculture has historically integrated agroecological practices within its regulatory framework; however, questions remain as to the...
متن کاملModelling tillage and nitrogen fertilization effects on soil organic carbon
1 Agricultural management plays an important role in global warming mitigation due to 2 its effects on soil organic carbon (SOC) dynamics. In Mediterranean agroecosystems, 3 the interactive effects of tillage and N fertilization on SOC storage have scarcely been 4 studied. Hence, we here present a modelling study in which the effects of both tillage 5 and N fertilization on SOC dynamics are inv...
