Nutrient distribution in three contrasting soils after anaerobic baffled reactor effluent application: A soil column study

Urban Farm DB summary

This soil column study investigated the effects of anaerobic baffled reactor (ABR) effluent on chemical properties of three contrasting soils, relevant to peri-urban agriculture. Soil columns were leached with ABR effluent or distilled water using 16 pore volumes, then sectioned and analyzed for inorganic-N, P, and K. For all soils, nutrient content, particularly phosphorus, in the 0-2 cm layer was significantly higher than in the middle and bottom sections of the columns. Significant differences in phosphorus accumulation were observed between effluent-leached and water-leached soils.
