Spring soil samples collected prior to effluent application indicated soil pH in the 0 treatment as being higher than any of the treatments. Most of the phosphorus in the effluent stayed in the 0-8 inch zone. Potassium levels continued to rise with increasing effluent rates. Organic matter content does appear to increase with effluent rates. The Soluble Salts content tended to vary with respect to depth.
Organic matter does increase slightly at the lower sampling depth with the higher rates.
Soluble salts appear to be moving away from the point of injection.
