“…Iron deficiency chlorosis is commonly controlled by using soil fertilisation with Fe(III)‐chelates ( Abadía et al., ; El‐Jendoubi et al., ). However, foliar fertilisation is also being used, since when applied adequately it can correct the deficiencies of Fe and other micronutrients ( Fernández et al., ; El‐Jendoubi et al., ; Rios et al., ).…”

It has been proposed that glutathione can relieve the effects of Fe deficiency. This study tested the effects of glutathione foliar treatments to prevent Fe chlorosis, using as positive controls soil and foliar Fe fertilisation. Medicago scutellata plants were grown in soil (5.7% CaCO3) supplemented or not with 4 and 8% CaCO3. Two Fe(III)‐EDDHA soil treatments (5 and 10 mg Fe kg−1), and three foliar treatments (three applications each of 2.14 mM Fe(III)‐EDDHA, 1 mM glutathione, and the previous two combined) were applied. Measurements include leaf chlorophyll and Fe concentrations, biomass, leaf enzymatic and non‐enzymatic antioxidant systems and carboxylates. The addition of CaCO3 caused typical Fe deficiency symptoms, including changes in chlorophyll, Fe, antioxidant systems and carboxylates, which were prevented by soil and foliar Fe fertilisation. The foliar treatment with glutathione also led to higher chlorophyll, leaf extractable Fe and root Fe, as well as decreases in some antioxidant systems, whereas leaf Fe concentrations decreased. The combined foliar application of glutathione and Fe was even more efficient in preventing chlorosis. Including glutathione in foliar fertilisation programs should be considered as an option for Fe chlorosis prevention, especially when relatively large leaf total Fe concentrations occur in the so called chlorosis paradox.

“…A number of studies have shown that one of the most serious problems of crops cultivated in alkaline/calcareous soils is iron (Fe) deficiency. The presence of high concentrations of bicarbonate along with basic pH favours the precipitation of Fe hydroxides and oxides, thus causing a very significant reduction in Fe bioavailability 1, 2. This deficiency in Fe availability is frequently associated with leaf chlorosis and an important decline in crop yield and quality 1, 3…”

“…Although the ability of the vegetal extract to solubilize Fe in the soil was relatively low, it should be considered that fruit trees have low Fe requirements. For instance, Abadía et al (2004) reported that Fe requirements in mature peach trees range between 1 and 2 g of Fe per tree per year. For kiwifruit, total removal of Fe in fruits was estimated around 160 g ha À1 for a fruit load of 30 t ha…”

The aim of this study was to evaluate the effectiveness of soil-applied aqueous extract of Amaranthus retroflexus L. in preventing lime-induced iron (Fe) chlorosis of pear trees (Pyrus communis L.). Tree growth, nutritional status, yield and fruit quality were also assessed. The aqueous extract was obtained by soaking dried and ground canopy (epigeal part) of spontaneous A. retroflexus plants in tap water. A. retroflexus extract was chosen because of its ability to solubilize Fe from calcareous soil, which was found to be 100-fold higher than deionized water alone. Two experiments were carried out (controlled environment and commercial field conditions) where soil-applied aqueous extract of A. retroflexus alone or mixed with iron sulfate (FeSO 4 ) was compared with synthetic Fe-chelate and an untreated control. Soil-applied aqueous extract of A. retroflexus increased shoot length, leaf SPAD and total plant biomass in controlled environment. In the commercial orchard control trees showed severe leaf Fe-chlorosis symptoms effectively prevented by Fe-chelate. The supply of A. retroflexus aqueous extract improved Fe nutrition of trees, particularly when enriched with FeSO 4 . Fe-chelate increased tree yield but decreased fruit weight, leaf potassium (K) and manganese (Mn) concentration. At harvest, all strategies raised fruit soluble solid concentration compared to the untreated control. Results showed that soil-applied A. retroflexus aqueous extract improved Fe nutritional status of pear trees, probably because of the natural Fe chelating capacity of the compounds released by its tissues.
