What percentage of these nutrients will be available for next season's crop growth? Below is a nutrient removal chart for 200 bushel corn, tracking what is removed by the grain and what is left behind in the stalk/residue. Typically, there’s a great deal of potassium (about 80% of the applied K) left in the crop residue after harvest, along with 40% of the applied nitrogen and 25% of the applied phosphorous. At today's prices, these tied-up nutrients have a value of over $125 per acre! **Corn at 200 Bushels** [![Corn at 200 bushels](https://blog.agricen.com/hs-fs/file-675980482-jpg/blog-files/chart.jpg?width=502&height=132&name=chart.jpg "CHART")](https://blog.agricen.com/hs-fs/file-675980482-jpg/blog-files/chart.jpg) *Chart produced using The Mosaic Company’s *[*Nutrient Removal App*](http://www.agprofessional.com/news/Mosaic-introduces-new-nutrient-removal-data-app-135169923.html).* For more information and resources, please visit their “*[*Back to Basics*](http://www.back-to-basics.net/)*” soil fertility site*. What options are available to growers who want to access these nutrients? One accepted practice has been to apply 10-15 gallons of UAN after harvest in the fall to assist with microbial decomposition of crop residue and to accelerate nutrient release. The downfall of this approach is that microbial decomposition slows and eventually stops as soil temperatures drop below 40° F. Today, we also have a biochemical fertilizer catalyst, [Accomplish® LM](http://www.amsag.com/products/accomplish/), which works to release tied-up nutrients (regardless of soil temperatures) and increase crop yields—all for a lower price than a fall UAN application.
