 ttps://iastate.zoom.us/j/91411984892.\n\n\n\n\n\n\n\nIowa Learning Farms
 \, in partnership with the Iowa Nutrient Research Center\, is hosting a 
 free virtual field day on Thursday\, December 4 at 1 p.m. CT.  Join us 
 for a live discussion with Dr. Mike Castellano\, William T. Frankenberge
 r Professor of Soil Science at Iowa State University.\nThere is growing 
 evidence that the amount of both corn and soybean residue affect the opt
 imum nitrogen fertilizer rate to the following corn crop. Higher levels 
 of residue lead to higher optimum nitrogen fertilizer rates. However\, r
 ecommended nitrogen fertilizer rates do not consider the amount of resid
 ue from the previous crop. The virtual field day will highlight this inn
 ovative research project examining the ability for farmers to adjust opt
 imum nitrogen fertilizer rates based on the amount of corn and soybean r
 esidue production in the previous year’s crop and improve water qualit
 y outcomes.\n“The current solution for crop residue management is ofte
 n intensive tillage in the fall or even in the spring. We believe an alt
 ernative to tillage to deal with crop residue management can be the part
 ial residue harvest. So roughly harvesting about 60% of crop residue wou
 ld take us back to about the residue produced in around 1975\, but pairi
 ng residue harvest with no-tillage or cover crops would benefit soil hea
 lth\,” commented Dr. Castellano. “One of the particular things that 
 we're interested in testing at this field is whether partial residue har
 vest improves water quality outcomes. How could partial harvest residue 
 harvest improve water quality outcomes? That seems like it might be a li
 ttle bit of a surprise.”\nTune into the field day live to learn more a
 nd participants are encouraged to ask questions of the presenters. Peopl
 e from all backgrounds and areas of interest are encouraged to join.\nVi
