Leaching and volatile losses of N from some southern California soils were studied when various nitrogenous fertilizers were broadcast and unincorporated. Under sprinkler irrigation, substantial leaching losses occurred with Ca(NO3)2. Manure was an inefficient source of N. Substantial volatile losses of NH3 occurred with urea on calcareous as well as acid soils. In comparative studies of atmospheric NH3 loss, the order of magnitude was urea>(NH4)2SO4>NH4NO3> urea-formaldehyde.
