As with other wastes, always have your lagoon sludge analyzed for its nutrient value.
Lagoon sludge has a much higher phosphorus content than lagoon liquid.
- sludge should be applied to land with low phosphorus, as indicated by a soil test, and incorporated to reduce the chance of erosion
- sludge applied to fields with high soil test phosphorus should be applied only at rates equal to the crop removal of phosphorus
