“…Iron deficiency is a worldwide problem as calcareous soils cover over 30 % of the earth's land surface (Basar et al, 2014), especially in arid and semiarid regions, and it has a large economical impact because crop quality and yield can be severely compromised (El-Jendoubi et al, 2014;Rombolà and Tagliavini, 2006); thus, several methods of correction have been developed. Iron canopy fertilization (foliar fertilization) can be a cheaper, more environmentallyfriendly alternative to soil treatments with synthetic Fe(III) chelates for the control of Fe chlorosis in fruit trees (Fernández et al, 2013).…”

Abstract. Power stations, ships and air traffic are among the most potent greenhouse gas emitters and are primarily responsible for global warming. Iron salt aerosols (ISAs), composed partly of iron and chloride, exert a cooling effect on climate in several ways. This article aims firstly to examine all direct and indirect natural climate cooling mechanisms driven by ISA tropospheric aerosol particles, showing their cooperation and interaction within the different environmental compartments. Secondly, it looks at a proposal to enhance the cooling effects of ISA in order to reach the optimistic target of the Paris climate agreement to limit the global temperature increase between 1.5 and 2 • C.Mineral dust played an important role during the glacial periods; by using mineral dust as a natural analogue tool and by mimicking the same method used in nature, the proposed ISA method might be able to reduce and stop climate warming. The first estimations made in this article show that by doubling the current natural iron emissions by ISA into the troposphere, i.e., by about 0.3 Tg Fe yr −1 , artificial ISA would enable the prevention or even reversal of global warming. The ISA method proposed integrates technical and economically feasible tools.

“…The most visible and recognizable symptom of Fe-deficiency in most of the susceptible crops is interveinal yellowing starting from apical leaves (Rombolà and Tagliavini 2006), while in pear leaf Fe chlorosis appearance is atypical, since it often occurs in the whole leaf lamina, including veins (Abadía et al 1999). In our experiments, potted untreated trees showed growth depression prior to the typical chlorosis of the leaves.…”

“…Lime-induced iron (Fe) chlorosis represents the most important nutritional disorder of susceptible fruit crops especially when cultivated on alkaline-calcareous soils (Rombolà and Tagliavini 2006) which represent approximately 39% of world soils (Ç elik and Katkat 2010). Fe chlorosis in crops occurs mainly as a consequence of a scarce solubility of mineral Fe sources in the soil and of a reduced Fe uptake by the symplast, induced by the soil active lime fraction (Tagliavini and Rombolà 2001).…”

“…is adopted as rootstock, pear is one of the species most susceptible to Fe chlorosis (Rombolà and Tagliavini 2006). Although synthetic Fe-containing compounds such as Fe-chelate (e.g., Fe-EDDHA) are usually effective in overcoming Fe-deficiency disorder (Lucena 2003(Lucena , 2006, they induce a short-lasting re-greening effect, are expensive (Tagliavini and Rombolà 2001) and represent a risk of water table contamination.…”

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.

“…There are many reports describing yield reductions caused by Fe deficiency in field crops (Hansen et al, 2006) and in fruits (Rombola and Tagliavini, 2006) and the detrimental effects of Fe-chlorosis on both fruit yield and quality (Álvarez-Fernández et al, 2006). The differences in sensitivity to Fe deficiency among plant species have been reported by several researchers (Vose, 1982;Awad et al, 1994;Tagliavini and Rombola, 2001;Erdal et al, 2004;Álvarez-Fernández et al, 2011;Pestana et al, 2012;Zuo and Zhang, 2011), and the strawberry is one of the most sensitive species to Fe deficiency (Vose, 1982;Zaiter et al, 1993;Álvarez-Fernández et al, 2006;Kafkas et al, 2007;Pestana et al, 2011Pestana et al, , 2012.…”
