DESCRIPTION: \n\nPhD Oral Defense of Leonardo Xavier León Castro\, Natural 
 Resource Sciences.\n\nGreen manure crop mixtures contain legumes that capt
 ure N2 from the atmosphere. When green manure is plowed down\, the decompo
 sing residues are a source of N fertilizer for the following crop. The cha
 llenge is to determine how quickly the green manure releases N and what pr
 oportion of the N requirements of the next crop can be met by green manure
 . Ion exchange membranes (IEMs) hold promise in evaluating the N supplied 
 by green manure\, and they act as a sink for plant-available N. The object
 ives of my thesis were to 1) determine the pattern of N release from field
  pea-oat green manure under field conditions with IEMs\, and relate this t
 o the N demands of arugula (Eruca sativa L.)\; 2) to determine if IEMs cou
 ld detect small changes in N dynamics in different soil types that were am
 ended with green manure residues having a low C/N ratio\; and 3) to determ
 ine how tillage practices that reduce the size of green manure residues ma
 y accelerate N release from green manure\, as determined by IEMs\, and  me
 et crop N requirements.  \n\nEveryone in the 91ºÚÁÏÍø community is welcome t
 o attend a PhD oral defense. Please join us in celebrating the accomplishm
 ents of our PhD candidates.\n\n \n\n \n
