“…In the study by Narwal et al (2012), foliar application of Zn, Fe, and Mn increased the content of those minerals in the grain of 14 varieties of winter wheat. According to Kutman et al (2011), enriching N fertilization with Zn in the form of foliar fertilizers increased Zn and Fe content in the grain.…”

“…Since Se is assimilated in plants via S assimilation pathway, over-expression of sulphate transporters in Zn treated plants might be the reason for more efficient Se assimilation. In addition it was recently demonstrated that the N nutritional status of plants has a critical role in Zn and Fe biofortification of wheat grain, with increased N inducing protein synthesis in grain, and thus creating additional Zn and Fe sinks (Kutman et al 2011). Thus, potential interactions of elements should never be neglected when the aim is to alter the mineral composition of grain.…”

“…For example, foliar or combined soil/foliar application of Zn fertilisers under field conditions was shown to effectively increase Zn concentrations in whole wheat grain (e.g., by 3-fold; Cakmak 2008). Recently, N fertilisation was shown to positively affect Zn and Fe concentrations in wheat grain (Kutman et al 2011), which confirms that the plant mineral status as a whole can respond readily to (even single) mineral changes in the soil solution.…”

Optimisation of the concentrations of essential mineral elements in staple grain diet and reduction in non-essential and potentially toxic elements would considerably alleviate mineral malnutrition and improve the health of humans. Here, wheat (Triticum aestivum L.) plants were biofortified with Zn and/or Se to determine the changes across 36 elements in the grain. The element concentrations were determined by multielemental k 0 -instrumental neutron activation analysis (k 0 -INAA). In comparison to grain from non-biofortified plants, Zn fertilisation increased the grain Zn, Ca, and Mo concentrations, whereas the foliar application of Se only increased the grain Se concentrations. Double biofortification (combined Zn fertilisation and foliar Se) was more effective for the increased Se concentrations in the grain, in comparison to the Se-only biofortified plants, with the grain Zn, Ca and Mo concentrations remained at the same levels as those for the Zn-only biofortified plants. Except for Ba, Br and Rb, the concentrations of the elements analysed were below the detection limits. Double biofortification might be a feasible strategy to efficiently coordinate the mineral quality of wheat grain, although the considerable concentrations of other essential and non-essential elements should not be neglected.

“…For example, N application can increase Zn uptake, xylem transport and remobilization via the phloem, and hence the concentration of Zn in the grain (Erenoglu et al 2002(Erenoglu et al , 2011Kutman et al 2010Kutman et al , 2011Xue et al 2012), while excessive P fertilisation can reduce availability of Zn in the soil (Marschner 1993;Lu et al 2011). Manzeke et al (2012) reported that farmer fields in Zimbabwe receiving cattle manure or leaf litter in combination with NPK had greater concentrations of EDTA-extractable Zn in soils and greater concentrations of Zn in maize grain compared to unfertilised fields or those receiving only NPK, while rotation with legumes was also reported to increase concentration of Zn in maize grain.…”

Zinc-enriched fertilisers as a potential public health intervention in Africa

Background In this review, we examine the potential of Zn-enriched fertilisers to alleviate human dietary Zn deficiency. The focus is on ten African countries where dietary Zn supply is low and where fertiliser subsidies are routinely deployed on cereal crops. Scope Dietary Zn supply and deficiency prevalence were quantified from food supply and composition data. Typical effects of soil (granular) and foliar Zn applications on Zn concentrations in maize (Zea mays L.), rice (Oryza sativa L.) and wheat (Triticum aestivum L.) grains were based on a systematic literature review. Reductions in disease burdens attributable to Zn deficiency and cost-effectiveness were estimated using a disability-adjusted life years (DALYs) approach. Conclusions Baseline Zn supply in 2009 ranged from 7.1 (Zambia) to 11.9 (Mali) mg capita −1 day −1
