Proceedings... Piracicaba: FEALQc2001  ap. 195-196.  aNitrate levels in soil profile after the first N application on coastcross pasture, grown on a dark red latosol (Hapludox), in Sao Carlos, SP, Brazil, under tropical altitude climate, were measured at 7-day intervals, to monitor possible losse in depth. Soil nitrate rates varied with high rates of N-ammonium nitrate (200kg ha per cutting) in surface layers. Danger of environmental impact was low in the studied conditions.  aammonium nitrate  aurea  acoastcross  aCynodom dactylon cv  aPasture  aSoil nitrate1 aPRIMAVESI, A. C.
