Newly-available program helps manage manureNebraska An online manure management planner that's getting new attention from University of Nebraska-Lincoln specialists, can help plan nutrient applications to croplands. A planner developed by Purdue University helps producers determine how much nutrient value they will get from manure, said Charles Wortmann, UNL nutrient management specialist. It calculates values on the basis of manure type and application rates. It helps estimate how much manure and fertilizer combined the land needs for optimal crop growth. Using the program, producers can develop an operational plan to decide which manure to apply to which field at what time and what rate with what equipment, Wortmann said. This planner is freely available online. It can be downloaded from the Internet and requires no special software, Wortmann said. To find it, search for the words manure management planner and Purdue. It's a product developed for nation-wide use. It includes information for each state, such as fertilizer or nutrient recommendations, so users should start by indicating their state. Wortmann said that many people will be able to use the program without training. Tutorials are available at http://www.agry.purdue.edu/mmp/. UNL helps Purdue with updates of Nebraska information, Wortmann said. Currently, UNL personnel are working with Purdue to provide information to feedlots. The planner is already strong for confined swine, dairy and poultry, but not so much for feedlots. It's harder to model conditions there, he said, because they're open to the atmosphere. "We're also working with Purdue to model changes resulting from wide-spread feeding of ethanol byproducts," Wortmann said. This program is new to UNL and Extension personnel have not yet been trained in its use, Wortmann said. He said that he's available at cwortmann2@unl.edu to help producers with problems they may have in using it. 4/21/08 Date: 4/16/08 Advertisement
