a) Total solids, and b) pH in soil with and without biosolids amendment irrigated with treated wastewater effluent or DI water over 77-day growth period of carrots from seed in a greenhouse setting. Total solids were measured weekly and pH was measured biweekly. On day 0, total solids and pH were measured before irrigation and after biosolids amendment. On all other sampling days, total solids and pH were measured prior to irrigation. Error bars represent standard error of three replicates.
