In this week's #FeedyardFriday, ISU Extension Livestock Specialist, Russ Euken discusses a few factors to consider when utilizing manure as fertilizer in order to optimize the value of the available nutrients. Check out the publication he mentions here https://store.extension.iastate.edu/product/12874
"Without a course correction mid-flight, you're already hurtling toward the earth in a pH nosedive, albeit at a snail's pace. Problem is, you don't realize the trajectory of your impending demise until it's too late. And it prompts a series of cascading in-field failures. If only you had kept up with liming, all this discomfort could have been prevented."
"If we could better synchronize the timing of the manure application to when the corn is growing and taking up nitrogen, we could reduce nitrous oxide missions. That also would help the crop and the farmer better capture the nitrogen that's available in that manure."
"Liming the soil to keep the pH in the optimal range for plants is a basic step to achieve adequate yields. As agricultural lime normally is a slow-reaction product, it is recommended to apply lime at least three months before planting. However, better late than never. If for any reason the soil was not limed three months before planting, there is no problem applying lime right before planting" (Dr. Luke Gatiboni, https://agfuse.com/rickfoster/posts/c0x2UklIOHlPb0hLY2t3MEdSeDN2dz09).

"After years of field and laboratory studies using radioactive nitrogen, a team of scientists led by Alan Bennett of the University of California, Davis, proved that the microbiota in the aerial roots were supplying 30 percent to 80 percent of the nitrogen requirements of the host plant. The landrace is not suitable for U.S fields, as it requires eight months to mature. But it is only a matter of time until this trait is incorporated into U.S. hybrids."
