How much can cloud seeding be effective to get artificial rain? What are possible consequences on soil fertility and human health?

Silver iodide is used to spray on the clouds to obtain artificial rain. Then what about chemical compounds? These compounds may get mixed up with rain drops and while raining may get mixed up in soil and water. An experiment may give water but reduces soil fertility, as read in the paper. It is also possible that the such water may be hazardous to human health. In this case how much can cloud seeding be useful?
