While the majority of carrots are cultivated in California, recent droughts and water use restrictions may impact the success of future crops. Even in states such as Wisconsin, where water is more abundant, crops still must overcome oscillating soil moisture regimes due to differences in soil drainage, water-holding capacity, and microclimate conditions, as well as the anticipated drier summers which are predicted to increase with climate change.
The production of organic peaches is extremely difficult under the humid conditions of the Southeast due to high pest and disease pressures, and the lack of effective, organically approved pesticides. Consequently, only very few growers have taken the risk and transitioned into organic peach farming. This proposal aims to provide growers in the Southeast with a new tool to reduce the risk of transitioning to organic production of peaches. This strategy consists of the use of paper bags to physically protect the fruit from pests and diseases to reduce reliance on spray applications.
This project aims at developing integrated irrigation practices that capitalize on soil health to improve the efficiency of irrigation water and decrease pest pressure and potential N losses of California organic processing tomato production. The current drought has dramatically decreased irrigation water allocated to organic tomato growers and there is an urgent need to test new irrigation strategies that reduce water inputs while maintaining product quality, nutrient supply and high productivity levels.
Organic vegetable growers need practical and cost-effective technology to reduce weed pressure and yield losses. In 2013-2014, OFRF funded Dr. Gladis Zinati at the Rodale Institute to perform laboratory and greenhouse trials on the weed suppressing ability of chemically- and biologically-designed compost extracts (DCE). Dr. Zinati found that DCEs with lower nitrate levels and greater nematode-to-protozoa ratios significantly reduced lambsquarter weed seed germination by 32% without affecting crop seed percent germination.
The principal objective of this project was to make a greater proportion of relevant and practical research-based information available to organic farmers. Experienced organic farmers were specifically targeted. In the original proposal, NCAT planned to create a quarterly publication featuring abstracts of relevant research gleaned from the literature. Emphasis was to be placed on recent, cutting-edge research on a broad range of topics pertinent to organic production and marketing.
The organic industry is on track for a six-fold increase in the next five years, having grown from $6.1 billion in sales in 2000 to $29.2 billion in sales in 2011 (4.2% of total food sales in the U.S that year). Consumer demand continues to drive steady growth of this sector, which is indicated by average growth of 8% per year since 2002.
The purpose of this five-year breeding project is to reduce transgenic contamination of organic maize grown in the USA by maintaining the integrity of organic maize seed. Organic farmers are not required to produce transgene-free crops, but they must plant seed that is free of transgene. An important objective of this project is the education of seed producers and organic farmers on how to use these “Organic-Ready” varieties for reducing the incidence of transgenic contamination.
