This year between January and March in 2021, the Pastures for Profit curriculum will be offered as a virtual course.
The Pastures for Profit program is a collaboration between Ohio State University Extension, Central State University, USDA-Natural Resources Conservation Service, Ohio Federation of Soil and Water Conservation Districts, Ohio Department of Agriculture, and the Ohio Forage and Grasslands Council. One live webinar will be offered per month along with “work at your own pace” videos and exercises that accompany each webinar.
Event organizer, Christine Gelley, Ohio State extension educator in Noble County, welcomes organic participants. She sees pasture management as a naturally low-input farming system if it’s done right, relying on holistic thinking and species diversity.
Each webinar will be offered live on Zoom at 7 P.M. and feature three presentations in a 90-minute span. Attendees will be able to interact with the speakers and ask questions in real time. Once registered, attendees will be granted access to the online course including the webinars and complementary resources. Participants that attend all three webinars will have the opportunity to earn a certificate of completion. Registered participants will also receive their choice of a curriculum binder or USB drive of the traditional course by mail.

Sales of foliar fertilizers have skyrocketed in the last several years, particularly among organic dairy farmers. Foliar products are readily available, easy to store, and many products are approved for organic use and formulated to provide humates, microbiological products, micronutrients, and other popular treatments. Advocates of these products say they offer an environmentally friendly, efficient, and cost-effective way to apply fertilizers. Yet much of the recent research done on foliar feeding has been unable to reliably document benefits to production.
Louceline Fleuridor has spent the last two years studying foliar feeding as part of her Ohio State master’s degree program. She partnered with organic dairy farmers to measure the response of forage and soils to post-cutting foliar fertilization on 19 on-farm sites. As with previous studies in Ohio, Fleuridor found no consistent evidence of benefits from using foliar feeding products.
"In foliar feeding, you apply fertilizer through the leaves, which is contrary to the traditional knowledge that plants will absorb nutrients through their roots,” says Fleuridor, explaining that leaves' primary function is thought to be photosynthesis. "It raises some questions."
On Thursday, December 19, Fleuridor met with participating farmers and Ohio State specialists for a discussion of the research trials and results.
Partnering farmers began the meeting by sharing their experiences with foliar products. Wayne county dairy farmer Jeff Miller began experimenting with foliar feeding on one of his pastures five years ago. He decided to spray half of his pasture to see what would happen and because he couldn’t afford to spray the whole field. But when he noticed how much quicker his herd began to graze in the foliar fed area, he decided he couldn’t afford not to spray the whole field. Other farmers relayed similar experience, noting increases in crop yield, forage health, palatability, and harvested hay quality that coincided with the use of foliar feeding.
Yield gets a lot of attention in studies, but quality and palatability are also important, especially on dairy farms where forage is not the end product. Past studies have noted other advantages to foliar feeds, including decreased nutrient runoff, better absorption efficiency of micro- and macronutrients, reduced instance of disease, and, in a 2000 study on wheat, increased grain protein content.
"Forage quality is where we really expected to see changes, but we didn't," said Ohio State soil fertility specialist Steve Culman, who provided technical assistance on the project.
Fleuridor's study examined a variety of forage quality measurements, including in-field measurements for sugar content (Brix), as well as lab analysis for crude protein, stem:leaf ratio, fiber content, relative forage quality, net energy of lactation, and estimated milk/ton.
In addition to sharing individual and overall test results with the participating farmers, Fleuridor also spent time explaining how researchers use randomized plots and statistics to separate actual treatment differences from differences that happen randomly or from variations in the field. Fleuridor noted that there were some differences between the treatment and control in the studies, but the results were inconsistent and didn’t reveal a cohesive pattern of increased yield, plant health, or milk production for the sites in this study.
Culman cautions farmers to inform themselves before using foliar feeds. “If you’re looking at adding these products, look at the formulation and know what you’re getting. Foliar products tend to supply only a small amount of nutrients.”
Most of the farmers in the study plan to continue using foliar feeding, feeling that these products have caused improvements on their fields. They did note mixed results with some products and a need for additional labor. Several of the participants also stressed that other soil problems need to be fixed before turning attention to foliar feeds.
As for Fleuridor, she feels there are many factors that could have contributed to the mixed results in this study, including weather and soil conditions when the products were applied. She recommended that future studies use a consistent forage composition, and suggested a focus on clover may be advisable, based on farmer feedback.
This study was sponsored by The Ohio State University Paul C. and Edna H. Warner Grants for Sustainable Agriculture, Organic Valley FAFO (Farmers Advocating for Organic), and SoilBiotics. Organic Valley FAFO is currently accepting grant proposals for on-farm research projects. The deadline is February 15, 2020.

A smaller than usual corn harvest is underway in Ohio. A smaller than needed portion of the harvest continues to be organic.
According to annual acreage reports from Mercaris, a company specializing in market data and services for organic and non-GMO, the 2019 harvest will see a record number of organic grain acres, despite the notoriously poor spring planting season (1). But the firm also predicted a 12% decrease in actual organic corn yields, compared to 2018, which will lead to increased imports and costs for organic livestock farmers.(2)
For decades, consumer demand for organic food has grown annually by double-digits (3). While still a comparatively small portion of overall agricultural production, organic corn acreage in the U.S. increased by more than 55% between 2011 and 2016, driven mainly by demand from organic dairy farms (4). Despite the large increase in production, organic grain was imported to the U.S. in 2016, indicating the potential for future growth (5, 6). Currently, Ohio ranks in the top 5 states for number of certified organic corn growers, and in the top ten for acres harvested (7). However, relatively little is known about the management practices of these farms.
As part of an interdisciplinary study on soil balancing, Ohio State researchers surveyed certified organic corn growers in Ohio, Michigan, Pennsylvania, and Indiana in the spring of 2018. These four states collectively represent one-third of all U.S. organic corn growers and produce about 20% of the nation’s organic corn.
Responses show the majority of organic corn growers in this region are dairy farmers. More than half of the organic corn grown in 2017 was used as on-farm livestock feed. Most (70%) respondents harvested corn as grain corn; 36% harvested corn as silage (with some doing both). Other uses were rare. A surprisingly large number (nearly 2/3) of the growers use horse-powered equipment, indicating they are likely members of Old Order Amish or similar Plain communities.
The survey examined the use of soil amendments, crop rotations, cover crops, various tillage and cultivation strategies, yields, selling costs, and management priorities. Manure and compost were by far the most common practice, used by 89% of all organic corn growers. Other amendments were used by fewer than half the growers. Tillage practices were chosen for weed management, but most other management decisions focused on soil health.
Reported yields varied widely, ranging from 25 to 250 bushels per acre for grain and 5-34 tons per acre for silage. According to the data collected and estimated from survey responses, very few farmers lost money on the fields reported on for this study.
Farmers with more years of experience raising crops organically tended to have higher net returns on average, suggesting that economic performance can be expected to improve over time for transitioning farms. About 40% of respondents had less than five years of experience farming organically.
Researchers received a 57% response rate (859 responses), yielding a margin of error of 2%.
