Lentils are important for diversifying wheat-based cropping systems and are also beneficial in enhancing soil health. These benefits have contributed to the exponential growth in pulse crop acreage in The Northern Great Plains (NGP). There are several challenges facing organic lentil production. Lack of approved herbicide for use in organic pulse crop production provides a challenge to weed management.
North Carolina is the second largest producer of organic sweet potatoes in the U.S., with a rapid 42% increase in acreage transitioning to organic from 2014 to 2016. Despite a steady demand for organic sweet potatoes, marketable yield often does not reach the yield potential for this region due to challenges in weed, insect and soil fertility management. Through farmer consultation soil borne pests such a wireworm and weed proliferation were identified as two areas of concern for organic farmers in North Carolina.
In the Midwest, one limitation faced by small- and mid-scale organic producers involving cover crop-based, no-till systems is the expense associated with equipment such as a roller crimper needed to terminate the cover crop for spring planting. Thus, the development of an effective no-till system that does not require the use of expensive equipment would be beneficial to producers.
Green manures (GMs) play an essential role in organic grain-based systems on the Canadian prairies by contributing to soil health, cash crop yield, and grain quality. While this is well documented on research farms, a recent scan conducted by the Prairie Organic Grain Initiative (POGI), indicated poor adoption of GMs and lack of proper GM management. The goal of this research project is to increase the use and proper management of GMs.
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.
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.
Objectives Statement a. To investigate the effectiveness of compost tea in suppressing fungal diseases of pumpkins and promoting overall crop health and yields; to demonstrate that compost tea can be an effective tool for managing fungal diseases when used as part of an organic / non-chemical farming system. Modification: The proposal was originally written with potato as the test crop. This was changed to pumpkin to ensure disease presence. b.
Our overall goal is to support the growth of an organic certified seed potato industry in Wisconsin. We have addressed this goal by conducting field trials on participating Wisconsin organic farms in order to test organic production methods for seed potatoes that meet certification standards. We used information from our field trials and from published literature to develop educational resources for organic growers on becoming certified seed potato growers using disease testing to monitor potato health and organic management strategies to control common potato diseases.
