Abstract
Abstract Using conventional soil and foliar spray applications to correct micronutrient deficiency in citrus has not been completely satisfactory. Therefore, this study was developed to test the effectiveness of micronutrient application through microirrigation (fertigation) at rates similar to those recommended for foliar spray application. Three field experiments were conducted on ‘Valencia’ orange [Citrus sinensis (L.) Osb.] trees to study the absorption of Fe, Mn, Zn, and Cu by periodically analyzing leaf samples. The effectiveness of fertigation with micronutriems was found to depend on the fertilizer source. Application of chelated Fe, Mn, and Zn through irrigation systems increased the concentrations of these micronutrients in the leaves. The nitrate forms of Fe, Mn, and Zn were ineffective, as was the sulfate form of Zn. The sulfate form of Mn was occasionally effective, but the sulfate form of Cu was very effective. The application of chelated micronutrients through fertigation shows promise in central Florida.
