Wet fall, warm winter leave abundance of manure

Farmers might have an opportunity to replace some commercial fertilizer on wheat and corn crops after an unusually wet fall and warm winter left livestock producers in the Eastern Corn Belt with an abundance of manure, says an Ohio State University Extension researcher.

Livestock producers have been pressed for manure storage because they've been unable to get out and apply it to saturated fields. But according to Glen Arnold, they can turn the unplanned excess into opportunity by using it as a field crop fertilizer.

While manure has long been a viable fertilizer option, the time and high costs associated with transporting it, coupled with the convenience and efficacy of synthetic fertilizers, have limited its application to summer and fall months post-harvest. But as commercial fertilizer costs have risen sharply in recent years, Arnold said more farmers might now be interested in applying manure as wheat and corn crops are growing - especially since the nutrients are in their manure storage facilities waiting to be used.

"A relatively small percentage of farmers apply manure to growing crops at this time, but we think that will increase once more people see the benefit and cost savings," he said. "Farmers are creative business people, and when they see how well manure works they'll come up with innovative ways to make it work for their operations."

Arnold, whose field research includes use of livestock manure on growing crops, said he has found that farmers can benefit financially by using manure. He also has found that more of the nutrients - nitrogen and phosphorus in particular - are better used when applied to the crop while it's growing instead of when fields are bare.

" Incorporating manure intro growing crops is a great way to keep phosphorus from escaping into surface waters," he said.

Arnold will hold a workshop March 1 about manure as a fertilizer on growing crops, 7-9 p.m. at the Putnam County office of OSU Extension, 124 Putnam Parkway, Ottawa. Registration is $10 in advance or $15 at the door. Participants can register for the workshop by calling 419-422-3851.

He also will present on March 7 at the Conservation Tillage and Technology Conference. The talk, which begins at 8:30 a.m., will offer strategies and tips for growers to consider applying manure as a field nutrient in April, May and June - an application window Arnold said many farmers haven't fully explored.

The Conservation Tillage and Technology Conference is sponsored by OSU Extension, the Ohio Agricultural Research and Development Center, Northwest Ohio Soil and Water Conservation Districts, the U.S. Department of Agriculture's Natural Resources Conservation Service, and the Ohio No-Till Council.

The full schedule and registration information can be found at http://ctc.osu.edu

Participants can register online or by mail. Registration for the full conference is $80 (or $60 for one day) if received by Feb. 24. More information also is available in county offices of OSU Extension.

It is very interesting imformation. Suraly animal manure is useful fertilizer for plants grwoing in Japan. Long time ago our ancesters were making fertilizer by rice straw animal waste even human. This winter the US is warmer than previous years. So that people can spread the manure to the crop field. It is help to save the cost of chemical fertilizer. But I concern the quality of the manure. If the manure turn into the compsost that may not expect the chemical fertilizer. And the manure has urine that may have much pottacium.
