Phosphorus Vertical Migration in Aquic Brown Soil and Light Chernozem Under Different Phosphorous Application Rate: A Soil Column Leaching Experiment

Phosphorus Vertical Migration in Aquic Brown Soil and Light Chernozem Under Different Phosphorous... A soil column leaching experiment was conducted to study the vertical migration of phosphorus in aquic brown soil and light chernozem under different phosphorus fertilization rates. The results showed that total dissolved phosphorus concentration in the leachates from the two soils was nearly the same, but dissolved inorganic phosphorus concentration was obviously different. In all fertilization treatments, aquic brown soil had a higher content of phosphorus in calcium chloride extracts compared with light chernozem. But Olsen phosphorus content was higher at the soil depth beneath 0–20 cm, and increased with increasing phosphorus application rate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of Environmental Contamination and Toxicology Springer Journals

Abstract

A soil column leaching experiment was conducted to study the vertical migration of phosphorus in aquic brown soil and light chernozem under different phosphorus fertilization rates. The results showed that total dissolved phosphorus concentration in the leachates from the two soils was nearly the same, but dissolved inorganic phosphorus concentration was obviously different. In all fertilization treatments, aquic brown soil had a higher content of phosphorus in calcium chloride extracts compared with light chernozem. But Olsen phosphorus content was higher at the soil depth beneath 0–20 cm, and increased with increasing phosphorus application rate.
