“…Iron chlorosis is widespread in numerous crops grown on calcareous soils and results in significant yield losses (Anderson, 1982). The problem is usually corrected by using iron synthetic chelates; however, these can be very expensive.…”

The possibility of using converter slag as an iron (Fe) fertilizer in some calcareous soils was investigated. Slag used contained 16.83% Fe 2 O 3 and 6.87% FeO plus a relatively large amount of calcium, silicon, phosphorus, and manganese. An incubation study was conducted with 3 calcareous soils for up to 60 days and the treatments included various amounts of slag (alone and mixed with elemental sulfur and alfalfa powder). Results showed that application of slag increased ammonium bicarbonateÁdiethylenetriaminepentaacetic acid-extractable Fe and pH in soils. The pot experiment was conducted with two different calcareous soils and corn (variety 647 Single Cross) as test plant. Treatments included various mixtures of converter slag with alfalfa powder, as well as ferric ethylenediaminedi(o-hydroxyphenylacetate). Results showed that application of 0.5 and 1% converter slag (based on soil dry mass) remarkably increased shoot dry matter and Fe, Mn, K, and P uptake. In general, there is a promising potential for converter slag to be used as an inexpensive source of available Fe for correction of Fe chlorosis in different crops in calcareous soils. This, however, needs further studies in the field and with various crops to determine the correct rates and to study the residual and environmental impact of application of this material to the soil.

“…Chlorosis (yellowing) is associated with iron deficiency in plants on land (Anderson, 1982;Mengel and Geurtzen, 1986), but the chemistry of iron in soils and its availability to plants (Lindsay and Schwab, 1982) is outside the scope of this review; thus, only a brief overview is given. However, while small amounts are necessary for growth, iron can become toxic to plants.…”

“…This is in contrast to the iron biogeochemical cycle in soil and land, as almost no recent publications details the current knowledge about iron in soils and over the landscape (Anderson, 1982;Lindsay and Schwab, 1982;Mengel and Geurtzen, 1986), a task we attempt in this review.…”

Climate engineering by mimicking natural dust climate control: the iron salt aerosol method

et al. 2017

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.

“…Chopped sorghum stover was mixed with the various Fe rates and incorporated into the soil at a rate of 2500 ppm to evaluate the complexing potential. The test soil was a Weesatch fine loamy soil classified as a mixed, hyperthermic Typic Argiustoll which had consistently produced severe chlorosis in other investigations (1,2,3). One kg of this soil was placed in pots with the following treatments:…”
