Urban Farm DB summary
This study analyzed runoff water quality from four different nutrient management treatments (conventional fertilizer, organic fertilizer, low-compost + organic fertilizer, and high compost) in raised beds and small plastic pool container plots in the United States. Water samples, collected monthly, were analyzed for pH, conductivity, color, turbidity, nitrate-nitrogen, ammonia-nitrogen, total phosphorus, and potassium. While significant differences existed between raised beds and container plots, these did not translate to meaningful water quality differences for most variables, except for nitrate-nitrogen. The conventional fertilizer treatment showed greater or more variable nutrient leaching than other treatments.
