Measurements of oxygen and carbon dioxide concentration, temperature, pH, and moisture content
are collected each week before turning. Concentrations of PAHs, nitrogen, phosphorus, and other
parameters are collected at the end of each month. On the basis of these results, water and/or nutrient
additions are made. Target ranges for selected parameters are listed in Table 2.
