Abstract
Sorghum which is susceptible to Fe deficiency was grown in 2 different soils in a glasshouse with 2 different organic urban wastes (sewage sludge and dog manure) to ascertain their ability to supply Fe and other trace elements to plants. One soil was calcareous with a history of Fe deficiency. Sewage sludge and dog manure at an application rate of 15 000 mu g/g to this soil effectively supplied Fe to plants. This effect was not present when the ash rather than the OM was used. FeSO4 and Fe-EDDHA likewise were not effective. Infrared spectra revealed differences in the fulvic acid for the 2 sources of solid wastes. The results imply that some sources of organic wastes may be useful in prevention or correction of Fe deficiency in calcareous soils
