Abstract

The results of field experiments over use of the composted sewage sludge compared with mineral fertilizer in corn crops are presented. Also, the nitrate leaching through the unsaturated zone and its arrival to groundwater is studied. The amount of nitrate adds from the composted sewage sludge is lesser than the traditionally fertilizers. This can substitute the traditionally fertilizers, because reduced the possibility of contamination and equaled the yield.
