Protecting water and the environment

Future of farming includes precision tech, smart use of ‘big data’

Modern farm machinery and unmanned aerial vehicles are opening new doors for the collection of valuable data to help growers improve production and the environment.

Modern farm machinery and unmanned aerial vehicles are opening new doors for the collection of valuable data to help growers improve production and the environment.

In the world of agriculture, having access to rich data sources about field conditions, weather patterns, pests and more can make a huge difference in the profitability and sustainability of Ohio farms.

The Ohio Agricultural Research and Development Center is working with farmers, industry groups and state agencies to boost access to and analysis of field data gathered from new-generation farm machinery, satellite data and remote-sensing imagery captured by unmanned aerial vehicles (UAVs).

“Data can support farmers’ management decisions, for example how much nitrogen should be applied to corn and whether or when a fungicide needs to be used,” OARDC and Ohio State University Extension precision agriculture specialist John Fulton said. “But all this enormous amount of data needs to be gathered and provided quickly for farmers to make the best use of it.”

A key goal of Fulton’s work is to create a repository that will then be made available to growers in a user-friendly manner to help them make data-driven decisions.

ESSENTIALS

The enhanced use of precision farming technology and “big data” analysis can benefit the agricultural industry and society in three key areas.

  • Economy: Providing remote-sensing imagery and other types of data to growers and their crop consultants can help growers make more efficient use of fertilizers and other expensive inputs, thus lowering costs.
  • Environment: Reducing fertilizer and agrochemical applications benefits the environment, protecting water, pollinators and other valuable natural resources.
  • Research: Developing an extensive data repository can help university scientists save time in their research projects and develop innovative recommendations to assist both farmers and the environment.

New OARDC garden will help study links between plants and health

“I’m an Ohio State grad. My grandfather and father came from Wooster. This is something I wanted to do for the university. I believe plants are very important in people’s health, and I hope this garden will be beneficial for people of all ages in the community, as well as for research.” — Bill Lemmon, president and owner, Lemmon & Lemmon Inc.

— Bill Lemmon, president and owner, Lemmon & Lemmon Inc.

The Ohio Agricultural Research and Development Center’s Secrest Arboretum has many gardens, but its newest addition stands out for its therapeutic and research value.

Established in summer 2015, The Lemmon and Rice Health and Wellness Garden was designed to boost visitors’ sense of well-being and provide opportunities for research into the impact gardens and nature have on human health. The garden was constructed thanks to donations from Bill Lemmon, president and owner of Lemmon & Lemmon Inc., and Kevin Rice, vice president of Rice’s Nursery and Landscaping, both located in the Canton area.

This is one of the country’s few gardens designed around the concept of the pillars of wellness. The garden focuses on six of the nine pillars: environmental, physical, intellectual, emotional, spiritual and social. OARDC has teamed up with The Ohio State University College of Nursing to conduct future research in the garden.

“Many visitors already use the arboretum as a part of their wellness program,” said Joe Cochran, Secrest’s interim director. “One visitor told me he had lost 36 pounds somewhere on the paths throughout the gardens.”

ESSENTIALS

Studies have shown the benefits of gardens and other outdoor spaces on health and wellness.

• Gardening 3–5 times a week has been found to be a good strategy to combat obesity and lower stress.
• Patients with musculoskeletal pain taking part in horticultural therapy programs experience an improved ability to cope with chronic pain.
• Children with attention deficit disorder who play in grassy, outdoor spaces have less severe symptoms than those who play in windowless, indoor settings.
• Dementia patients who have access to gardens are less likely to display aggression or suffer injuries, and they display improved sleep patterns, balanced hormones and decreased agitation.

Project works to improve Ohio water quality, one farm at a time

Long after Toledo’s water supply was cut for days in August 2014, researchers such as Jay Martin have continued to work to improve water quality throughout Ohio. (Photo: Ken Chamberlain, CFAES.)

Long after Toledo’s water supply was cut for days in August 2014, researchers such as Jay Martin have continued to work to improve water quality throughout Ohio. (Photo: Ken Chamberlain, CFAES.)

Field to Faucet was conceived by The Ohio State University College of Food, Agricultural, and Environmental Sciences. The college invested $1 million toward the effort after dangerous microcystin levels in Lake Erie shut down Toledo’s water supply for two days in August 2014.

Headed by Jay Martin, an ecological engineer in the college, Field to Faucet seeks to ensure safe drinking water while maintaining an economically productive agricultural sector. The goal is to reduce nutrient runoff and protect downstream ecosystems and water quality, helping farmers increase crop yields at the same time.

The initiative involves researchers from multiple colleges within Ohio State, as well as from other Ohio universities. Current research projects supported by Field to Faucet include a tri-state, cost-share program to help protect water quality in Ohio’s Western Lake Erie Basin, as well as the development of a weather-risk-management tool to warn farmers of impending storms to help lessen the risk of runoff from nutrient application.

“There continues to be pressure on farmers to be good stewards of our water resources,” said Scott Beck, president of Beck’s Hybrids, a partner on Field to Faucet. “Beck’s and the College of Food, Agricultural, and Environmental Sciences are conducting joint research to monitor water quality in different cropping scenarios over time. We are also looking at other agronomic studies such as fertilizer utilization and tile spacing.”

Essentials

Field to Faucet projects currently underway include:

  • Developing an app for farmers to record nutrient application rates and methods.
  • Developing a controlled-access, geospatial-data warehouse that allows producers and researchers to secure and share publicly available data.
  • Finding ways to best remove phosphorus and nitrogen from manure and anaerobic digester discharge before the materials are applied to fields. This effort will especially benefit the watershed around Grand Lake St. Marys in western Ohio.
  • Using unmanned aerial vehicles to provide real-time data on concentrations of microcystin created by harmful algal blooms in Lake Erie; and developing a sensor to detect real-time concentrations of microcystin in the lake.

4-H water projects are making a splash in Ohio, around nation

OSU, CFAES, 4-H, AG Innovators Experience

Ohio 4-H is leading efforts to help youths gain a deeper understanding of one of the most vital 21st century concerns: assuring access to fresh, clean water.

Water is rising in prominence in Ohio 4-H youth development activities.

In the Water Windmill Challenge, teams create mock-ups of wind-operated water supply systems.

“There are many possibilities of how to meet the challenge,” said creator Bob Horton, Ohio 4-H specialist. “If their structure fails, students quickly want to reinvent it. They don’t realize it, but this activity introduces them to engineering.”

 In Ways of Knowing Water, a project idea starter for individual 4-H members, activities help youths sharpen awareness about their local watershed and where their household water originates.
Meera Nadathur, 15, of Hamilton County, took the Ways of Knowing Water project and plans to study environmental sciences in college
“With 4-H, you get to actually experience what you’re learning
about,” she said. “You don’t just learn by reading about it. It really enhances the whole experience.”

In a new idea starter, Field to Faucet: Nutrients, Sediment and Water Quality, activities focus on preventing harmful algal blooms. Co-author and 4-H educator Jackie Krieger said, “For many around the world who have little access to fresh, clean water, we owe our best science and dedicated action to understanding this basic human need. Who knows what spark might be ignited in the minds of 4-H members by these activities?”

ESSENTIALS

OSU Extension’s 4-H STEM (science, technology, engineering and math) education program is making a mark regionally and nationally by developing projects including:

  • The Water Windmill Challenge. In 2015, nearly 10,000 youths in Ohio, Illinois, Indiana, Kansas, Nebraska, Missouri and Wisconsin participated in this challenge as part of the 4-H Ag Innovators Experience, sponsored by the National 4-H Council and Monsanto.
  • The Fish Farm Challenge, which was named as the 2014 4-H Ag Innovators Experience. More than 8,000 youths engineered a system to evenly dispense soy-based fish food pellets in an aquaculture tank.
  • The 4-H National Youth Science Experiment, the world’s largest youth-led science experiment. Ohio 4-H created the activities used in this program in 2008 and 2012.

High nitrate levels at a Columbus water plant last year led to a two-week, no-drink advisory for pregnant women and infants younger than 6 months old.

Preventing such problems drives the city of Columbus’ new, in-development Watershed Master Plan.

Consultancy CDM Smith leads the effort with help from, among others, specialists from Ohio State University Extension.

Myra Moss and Joe Bonnell, plus faculty emeritus Bill Grunkemeyer, are helping the firm identify and prioritize agricultural activities in the Scioto River, Big Walnut Creek and Alum Creek watersheds that could impact water reaching the city’s water plants.

Protecting Columbus’ watersheds “will help control treatment and reservoir operation costs and reduce risks in delivering safe drinking water,” said Julie McGill, water resources engineer with CDM Smith.

“The fewer contaminants entering the water plants,” said Bonnell, Extension’s watershed management program director, “the less technology — and money — required to remove those contaminants.”

Moss, Bonnell and Grunkemeyer have unique expertise in water issues, sustainable planning and consensus building.

“OSU Extension brings deep, unique experience in working with the agricultural community, developing comprehensive plans and delivering educational programs aimed at changing public behavior,” McGill said. “This lets them reach out to farmers and other stakeholders with simple, straightforward dialogue that can change mindsets.”

Essentials

  • Columbus’ Watershed Master Plan stands to benefit 1.1 million central Ohioans by safeguarding their drinking water sources and spending their water revenues wisely.
  • Columbus’ main drinking water sources, the Scioto River and Big Walnut Creek, receive runoff from 1,200-plus square miles of land, 72 percent of which is agricultural, before reaching the city’s Dublin Road and Hap Cremean water plants.
  • Runoff of fertilizer from farmland can be a major source of nitrates in the Scioto River.
  • Other challenges when treating Columbus’ water include atrazine, a weed killer; Cryptosporidium, a protozoan sometimes in manure runoff and failing septic systems; and phosphorus from fertilizer, which can contribute to harmful algal blooms.

Meera Nadathur, 15, wants to work in environmental sciences.

As a step toward that goal, the student at Cincinnati’s Sycamore High School last year completed Ohio 4-H’s Ways of Knowing Water project. It and some 200 other projects for Ohio 4-H members stress science and hands-on learning.

“One of my favorite experiences was visiting the Greater Cincinnati Water Works treatment plant to learn the entire drinking water purification process,” she said. “I was able to view every step of the process firsthand and gain knowledge about it from the very experts who ran the plant.”

A member of the Gorman Farm 4-H Club, Nadathur was one of the more than 200,000 youth ages 5-19 who participated in Ohio 4-H in 2014. Some 18,000 other Ohioans, including Nadathur’s club’s adviser, Cindy Capannari, helped as volunteers.

The organization, which is Ohio State University Extension’s youth development program, celebrated Ohio 4-H Week March 8-14. OSU Extension is the outreach arm of the College of Food, Agricultural, and Environmental Sciences at The Ohio State University.

Exploring water is especially timely given last year’s crisis in Toledo, said Joe Bonnell, OSU Extension’s program director for watershed management and one of the project’s developers. Last August, toxins from a Lake Erie algal bloom led that city to ban tap water use for three days.

Changes in climate, weather and land use, among other things, are more and more affecting Ohio’s rivers, lakes and streams, he said.

“I think the youth who complete this project will gain a greater appreciation for the value of water in their lives and communities, which hopefully will lead them to taking an active role in protecting their local water resources,” he said.

OSU Extension helps communities prepare for shale-related impacts

2014_OSUE_NB0050_adj

Shale workers keep area hotels filled to capacity. While that’s an economic boost, leaders like Norm Blanchard work to minimize the drawback of potential tourists being turned away.

In 2010, Guernsey County’s unemployment rate was 14.7 percent. Thanks to shale development, it tumbled to 5.7 percent by May 2014.

That’s all well and good, but the shale-related boom has other implications.

“A gas and oil guy from Midland, Texas, came to speak and told us to be prepared for our population to grow from about 11,500 to 100,000 in the next 15 years — at least, that’s what happened in Midland,” said Norm Blanchard, president of the Cambridge-Guernsey County Community Improvement Corporation. “When that hit the newspaper, we got calls. What are we doing to plan for this? How would we handle that kind of growth?” On the flip side, how should the region prepare for when shale development declines?

To help, Ohio State University Extension is tapping a $200,000 grant from the Economic Development Administration (EDA) to work with four regional EDA offices representing 25 eastern Ohio counties. Together they are examining shale’s economic, social and environmental impacts and developing plans for sustainable development.

Essentials

The OSU Extension project is:

  • gathering and analyzing volumes of data to track the area’s economic, social and environmental conditions, including measurements on employment, population, income, charitable giving, school enrollment, crime, housing, noise, traffic counts, air quality, and water quantity and quality.
  • examining the growth and contraction of specific industry segments. This will allow targeted actions to help local businesses adjust when the active shale construction phase ends.
  • identifying sectors that need local investment. In some areas, the focus might be on infrastructure; others might zero in on housing, community amenities, entrepreneurship or workforce training.
  • working with regional EDA offices to foster long-term planning across community and county lines.
  • piloting educational materials in Guernsey County, thanks to another $20,000 grant. Community leaders across the Midwest will be able to use the materials to incorporate shale development into their strategic planning.

“OSU Extension is not only giving us guidance, but they’ve been in touch with other states that have already been through shale development, and they’re providing us with that experience and expertise,” Blanchard said.  “It’s been invaluable.”

‘It blows their minds’: Challenges inspire youth to seek STEM careers

The Ohio State University is a partner of Global Impact STEM Academy, which offers hands-on learning in agbioscience fields, including food science, environmental sustainability, and biobased energy and products.

The Ohio State University is a partner of Global Impact STEM Academy, which offers hands-on learning in agbioscience fields, including food science, environmental sustainability, and biobased energy and products.

In 2012, the President’s Council of Advisors on Science and Technology predicted that over the next decade, U.S. industries will need one million more STEM graduates than the nation will have.

In 2013, Ohio State University Extension created the STEM Pathways signature program to spark enthusiasm in young people about science, technology, engineering and math. “STEM isn’t dry and boring. It’s fun, it’s exciting,” said Patty House, 4-H youth development educator and program leader. “You can use it to help solve real-world problems.” In its first year, STEM Pathways developed a dozen 30- to 60-minute challenges and attracted an estimated 8,500 participants across Ohio. Challenges were piloted at the Global Impact STEM Academy in Springfield, where director Josh Jennings is a huge proponent. “There’s no real prescribed step-by-step procedure they follow, because that’s the important thing: The students have to solve the problem on their own,” Jennings said. “When something happens they don’t expect, it kind of blows their minds.”

Essentials

STEM Pathways Challenge topics include diabetes, ergonomics, animal behavior, chemical spills, mining and bioproducts. One, the Fish Farm Challenge, was selected by the National 4-H Council and Monsanto to be the 2014 4-H Ag Innovators Experience for eight midwestern states. Leaders estimate 10,000 youth will participate in the challenge, designed to explore how to boost food production through aquaculture.

Here are some other 4-H initiatives:

  • Nearly 5,000 children and teens in Cleveland learn a lifelong appreciation of nature and understanding of natural resources through Youth Outdoors, a unique collaboration between Ohio 4-H, the City of Cleveland Division of Recreation, and Cleveland Metroparks: go.osu.edu/youthoutdoors.
  • Two urban schools, one each in Cleveland and in Cincinnati, host “4-H Agri-science in the City,” which provides hands-on classroom instruction as a complement to regular coursework, as well as afterschool and summer programs: go.osu.edu/cityagriscience.

“The whole idea of STEM is not just taking a rigorous engineering or mathematics course,” Jennings said. “STEM is a whole different process of looking at things. You present students with a problem, and they use their creativity and critical thinking skills to figure it out.”

Showing the benefits of tearing down dams: Healthier rivers, cleaner water

John Navarro poses along a restored stretch of the Olentangy River in Columbus. Removing a nearby obsolete dam helped key the restoration.

John Navarro poses along a restored stretch of the Olentangy River in Columbus. Removing a nearby obsolete dam helped key the restoration.

Tear down a dam, and a river will change. But how? And how much? To find out, Ohio Agricultural Research and Development Center scientists are looking in their own backyard.

Mazeika Sullivan and Kristin Jaeger are studying the impacts of dam removals at two former dams in Columbus: one on the Olentangy River on The Ohio State University’s Columbus campus, and another close by on the Scioto River. They’re documenting the exact changes seen in the rivers’ flow, biology and water quality.

“There’s a growing trend toward using dam removal to restore rivers, but studies documenting the rivers’ responses are limited,” said Sullivan.

“It’s logical to assume that removing a dam and restoring a river back to its natural state would provide an ecological boost,” said study sponsor John Navarro, program administrator with the Ohio Department of Natural Resources Division of Wildlife. “But until now, there have been few studies that quantify these benefits.”

Essentials 

  • Ohio has removed 60-plus dams in the past four decades, in large part to improve water quality.
  • A recent low-head dam removal project in Northeast Ohio, for example (not connected to the OARDC study), led to a previously impaired section of the Cuyahoga River meeting Ohio Environmental Protection Agency water quality standards within just six months — with fish diversity going up by 57 percent.
  • Dam removal cools a river’s water — about 6 degrees Fahrenheit in a previous study in Michigan — and restores its natural temperature range.
  • The improved water flow from dam removal keeps sediment from building up. Dam sediment can be full of accumulated toxins, including health threats such as polychlorinated biphenyls (PCBs).
  • Sullivan and Jaeger’s research is partly funded by a grant from the National Science Foundation.

Said Navarro, “The partnership between Ohio State and the ODNR Division of Wildlife, through the Ohio Biodiversity Conservation Partnership, supports the research being conducted by Mazeika and Kris, and will provide concrete evidence of the benefits of dam removals.”

Healthy bees, healthy agriculture: Striking a balance

Reed Johnson studies bee colonies at OARDC to learn more about factors affecting bee health. Healthy bees are crucial for both agricultural production and the environment.

Reed Johnson studies bee colonies at OARDC to learn more about factors affecting bee health. Healthy bees are crucial
for both agricultural production and the environment.

Bees are crucial to agriculture and food security. They pollinate about one-third of the crops we eat, valued at more than $14 billion annually in the U.S.

However, this valuable resource is at risk. During the 2013–2014 winter alone, Ohio beekeepers lost 50–80 percent of their honeybees. Bees are dying in large numbers due to many reasons, including diseases, insect pests, loss of habitat and agricultural chemicals.

“Most corn seeds planted today are coated with insecticides, and when they are chipped off in the planter, the dust lands on nearby flowers,” said entomologist Reed Johnson. “Bees then carry the tainted pollen back to their hives, where young members of the colony become exposed to it.”

Johnson is studying the unintended consequences of these insecticides as well as strategies to protect bees. For example, he has tested a lubricant that is applied to the seed to reduce dust, which shows promise in field trials.

Essentials

  • The Ohio Agricultural Research and Development Center and Ohio State University Extension work together with the beekeeping industry and others to deliver the following programs, which promote healthy bees and environments that boost bee numbers.
  • A monthly webinar series is attended by some 120 beekeepers from Ohio, other states and several countries. It focuses on ways to monitor for health issues and combat pests that attack bees. The sessions are archived online and reach many more beekeepers.
  • Monthly face-to-face educational programs with beekeeper associations throughout Ohio deal with topics such as integrated pest management and creating forage habitats for bees.
  • A statewide network of 28 research and demonstration gardens were planted in 2014 at schools, parks, arboreta and OSU Extension offices. The gardens evaluate which combinations of plants attract bees most, so that recommendations can be made to help enhance their habitats.

“Ohio State University research is required to provide information to the Ohio agriculture community, which will allow collaboration between beekeepers and farmers to help each other keep honeybees healthy and safe, and provide the pollination needed to keep crop production sustainable and profitable,” said Dwight Wells, regional director of the Ohio State Beekeepers Association.
