Water extracts of barnyard manure, when added to nutrient solutions, greatly decreased the absorption of zinc and iron during a 72‐hour absorption period. It was concluded that chelating agents held the zinc and iron in a form that was less available to plants than ionic forms and that the complexing agent did not increase the mobility of the metal within the plant. Additions of manure and a water extract of manure to a Brookston soil decreased the availability of zinc and copper in the soil, but increased the availability of manganese to the plants. It could not be determined from the data obtained whether or not the increased manganese availability could be attributed to the presence of the chelating agents in the extract.
