Wisconsin's landscape is a mix of livestock and grain farms. Nutrient management is important to both types of farm and trading feed for manure may benefit both.

Multi-crop annual forage production for improved manure management in Wisconsin

The objectives of this study was to develop annual forage crop systems that 1) create summer windows for manure spreading, 2) effectively utilizes the manure, 3) is economically as well as environmentally sound, 4) is competitive with corn silage yields, and 5) produces forage of high feeding value.

Orchardgrass Ley for Improved Manure Management in Wisconsin: II. Nutritive Value and Voluntary Intake by Dairy Heifers

ABSTRACT: Confinement dairy feeding operations in the Upper Midwest could benefit from utilizing a wider range of forages than alfalfa (Medicago sativa L.) and corn silage (Zea mays L.). A short term ley of orchardgrass (Dactylis glomerata L.) (OG) frequently treated with manured, was compared with corn silage (CS) in a [...] More »

Linking Dairy and Cash-Grain Farms in Wisconsin via Manure Transfer for Use in Grain Production: Corn (Zea Mays L.) Yield, Environmental Effects, and Implementation Constraints

ABSTRACT: One relatively under-utilized manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of a larger effort to [...] More »

Orchardgrass (Dactylis Glomerata L.) Ley for Improved Manure Management in Wisconsin: I. Forage Yield, Environmental Impact and Production Costs

ABSTRACT Spreading dairy manure in climatic zones with a short growing season that are dominated by full season crops such as corn (Zea mays L.) and alfalfa (Medicago sativa L.) is a challenge. However, replacing these with a grass ley does open several windows for manure spreading. The effects of such a strategy were [...] More »

Economics of Hauling Dairy Slurry and its Value in Wisconsin Corn (Zea Mays L.) Grain Systems

Abstract: To evaluate the potential of using dairy slurry for corn (Zea mays L.) production in Wisconsin grain systems, custom manure hauler bids were combined with corn production expenses to develop enterprise budgets in which slurry provided corn nutrient needs. A scenario was developed in which a recipient grain farmer shares manure hauling costs with [...] More »

Effects of Land Applying Dairy Slurry on the Subsequent Voluntary Intake of Orchardgrass Hays by Growing Dairy Heifers

Many dairy operations have a critical need for available sites to land apply dairy slurry after spring planting, and throughout the summer months. This is especially problematic when dairy producers have large proportions of their acreage planted to corn and alfalfa. One possible way to alleviate this problem is to use perennial grass sods as [...] More »

Alternative Cropping Systems for Improved Manure Management: The Grass Ley

Most dairy farms in the North central and Northeastern U.S.A. continue to grow most of their feed and recycle the manure nutrients on the farm. However, to remain economically viable, many dairy farms are increasing herd size and importing more feed nutrients onto the farm. The trend in Wisconsin and throughout the upper [...] More »

Effect of Dairy Slurry Application on Soil Compaction and Corn Yield in Southern Wisconsin

A B S T R A C T As stocking rates on Wisconsin dairy farms continue to increase, one possible nutrient management solution is to haul slurry to nearby grain farmer’s fields. Although the nutrient and soil building benefits of manure are well known, many grain farmers are hesitant to apply manure on their fields due to potential soil [...] More »

Effects of Dairy Manure and Weed Management on Weed Communities in Corn on Wisconsin Cash-grain Farms

A reason given by cash-grain farmers for not using manure from neighboring livestock operations is that manure may cause greater field weediness. To address this concern, trials were established in corn on 11 cash-grain farms, in which manure from six nearby dairy farms was spread for the first time in at least 10 yr. A [...] More »
