This study evaluates the effects of dairy lagoon effluent application on selected soil chemical properties, corn yield and nutrient uptake for an active dairy farm in New Mexico. Three fields were selected for comparison. The first field had received lagoon effluent for three years whereas only manure and lagoon solids had been applied to a second field. The third field not as intensively cropped as the other two fields and was considered as a control. Total corn yield from field 1 was about 2.7 ton ha-1 higher than that of field 2. Nitrogen and Potassium removed by corn were slightly elevated by lagoon effluent application. For field 1, soil EC1:5 values below 60 cm were relatively higher than that of field 2. Lagoon effluent application on field 1 indicated a 27% increase in NO3-N in the profile below 90 cm.
