The Potassium Test helped us see if the potassium level in the soil was correct. Potassium helps plants in dry weather. True
True or False: The PH test told us water is safe to consume, when the results are between 6.5 and 8.5 on the PH scale. True
True or False: When water tests about 10 mg/l on the nitrate chart, the water could be a health risk to consume. True
True or False: Phosphorus level is not a risk to health, but the level tells us how hard it will be to clean the water (by nature or the waste treatment plan) True
True or False: Leaching is when water takes metals from pipes (iron, lead, zinc, etc) and this is harmful to the consumer. Leaching occurs when the reading is lower than 6.5 on the PH scale. True
