"By all the breed standards, the Berks are number one in meat quality. They are also a rugged outdoor hog."

















"What stops my neighbors from doing [organic farming]? I think it’s the work, the record keeping and the uncertainly."








In an era when most farm families have at least one spouse working an off-farm job, Ron and Maria Rosmann have avoided the trend.

The two have developed a successful system of growing and direct marketing organic crops and livestock from their southwest Iowa farm near Harlan. The Rosmann farm is located 100 miles west of Des Moines and about 45 miles northeast of Omaha. With the assistance of their high school and college-age sons David, Daniel and Mark, the Rosmanns and one full-time employee are carving out a niche.

“We strongly believe in looking at the farm as a whole system. On our farm, the three biggest challenges are weeds, insects and fertility, but I love our switch to organics. I’ve seen better health in our soil because of it, and the farm has a better balance. What stops my neighbors from doing the same thing? I think it’s the work, the record keeping and the uncertainly,” Ron said.

Making the transition

Ron currently serves as the board president of the California-based Organic Farming Research Foundation. He is also an active member of Practical Farmers of Iowa, a non-profit organization that promotes farming systems that are profitable, ecologically sound, and good for families and communities.

While organic production is nothing new for the Rosmanns, they haven't always farmed that way. After graduating from Iowa State University in 1973, Ron returned to the farm to raise crops and livestock the conventional way for 10 years.

Ron never forgot the lessons his father taught him about the value of diversity on the farm, however. “My dad bought this farm in 1939, and he always believed in crop rotations and keeping livestock. He never gave up on oats, cattle, hogs or hay.”

Ron said he decided to go “cold turkey” into organic crop production and sustainable agriculture around 1983. “I got turned on to it by the Center for Rural Affairs in Nebraska. The first year, I used no herbicides on the corn. I did that with the beans, too, by the next year.”

Since 1994, the Rosmanns' 630-acre farm has had organic certification. The operation includes hogs, cattle, chickens, corn, oats, clear-hilum soybeans, rye, barley, turnips, pasture and hay. Currently, the farm income is derived from the direct marketing of livestock (15 percent); grain sales (50 percent); and organic beef and natural pork sales to other cooperatives and companies (35 percent).

The Rosmanns raise corn on about 190 acres. Sixty percent of the corn crop is white corn, and the family also produces organic seed for white corn. They grow soybeans on 80 acres, barley on 85 acres, oats on 37 acres, and have the rest of their land in hay, rye and pasture.

“We market our clear-hilum beans through Heartland Organic Marketing Co-op at Stuart, Iowa. This is a cooperative of organic farmers that has been in existence for around 10 years. Many of these beans end up as soy flour. Some also go for tofu, if the quality is good enough. Seed discoloration continues to be a big problem and is preventing more beans than ever from going into the high-quality tofu market. There is a desperate need for research on the mottling complex of viruses spread by the bean leaf beetle,” Ron said.

Some of the Rosmanns’ corn is also processed into food. “We market our white corn through a company in Colorado. The corn is used to make organic white corn chips, tortillas, and masa, which is the flour for making tortillas,” he explained. “Some is consumed here in the U.S. and some ends up in the European market. We feed some of our yellow corn to our livestock, along with oats and barley in the rations. We also sell some of our yellow corn for the organic livestock feeding market.”

“We’ve been at this for 19 years without herbicides on most of the fields. We’re ridge tillers. Ridge till works great on every weed except buttonweed (velvetleaf). To help control this weed, we’re thinking about changing rotations, or maybe planting fewer soybeans. The buttonweeds have been the worst in the beans,” Ron said.

While weed control can be a challenge, keeping grain pure from genetically-modified substances is a big issue, too, Ron noted. “We plant no GMO white corn hybrids, but we have had a sample show up with GMOs in it. Where did it come from? Did it come during shipping, or during lab testing? We don’t know for sure.”

GMOs raise concerns on another level, Ron added. “I question whether we’ve scratched the surface on GMO crops’ resistance to weeds and insects. It seems like we’re getting more disease and insect problems in crops around here. I think we need more research on GMOs and organic crops.”

Pork production

The Rosmanns feed one third to one half of their grain to their livestock. Ron plans to start feeding more barley and less corn in the rations. “We’re going to sell more corn, because it brings better returns. I also like barley in feed as a mix, but not as a single ingredient,” he said.

To boost their profitability, the Rosmanns intend to direct market more of their beef, pork and poultry. “We’re always pushing everything to make money. It helps when you don’t have to purchase as many inputs. It keeps your costs low. It seems like our biggest cost is trying to keep our old equipment running,” Ron said.

The Rosmanns have converted existing buildings to accommodate their 45-sow farrow-to-finish hog operation. They raise Berkshire hogs with a Swedish deep-bedding system. “By all the breed standards, the Berks are number one in meat quality. They are also a rugged outdoor hog,” Ron explained.

While the Rosmanns vaccinate their hogs, they have cut back on treatments. They use no antibiotics, and say there’s no substitute for a production system based on good bedding. They bale corn stalks to use for bedding.

Many of the hogs are sold through the conventional system, although the Rosmanns’ goal is to see how many hogs they can sell through their own direct-marketing program.

Rotational grazing for cattle

In addition to the hogs, the family has a 90-cow herd and say they are very pleased with their cow-calf operation.

“We have Red Angus, which is one of the best breeds around. We get our genetics from a breeder in the county who focuses on carcass quality and feed economics. He’s a very practical breeder who doesn’t believe in show cattle,” Ron said.

The Rosmanns raise cattle outside year-round, and the animals have access to shelter. Calving occurs twice a year. The Rosmanns said they strongly support rotational grazing practices, and their finishing cattle have access to pastures. “Raising animals humanely is very important to us,” Maria said.

In August, the Rosmanns plant turnips, rye and vetch so their cattle can graze this forage when grass pastures slow down. They say turnips provide an excellent cattle feed.

Currently, the family is working with researchers at Iowa State University to study conjugated linoleic acid (CLA) and beef cattle. CLA is a fatty acid found in beef and dairy fats that may contain cancer-fighting substances. The study compares finishing cattle completely on grain, versus feeding them on grass with minimum grain finishing for the last 120 days.

“We’re trying to find out if there’s a difference in economics and in beef taste, tenderness and CLA levels,” Ron said.

The Rosmanns round out their livestock operation with poultry production. The family raises 600 to 700 broilers each year.

Manure from the poultry, hog and cattle operations is composted in a long pile in a nearby field. “There’s no smell and no flies with this composted manure. We spread a lot of it on our fields in the fall,” Ron explained.
