Dec 16th 2020, economist.com: Wheat absorbs phosphorus from desert dust. After 12 millennia, a common crop still springs surprises, backup Citat: "...It helped itself to a dose of much-needed phosphorus when its leaves received a coating of desert dust...Then they scattered desert dust on the leaves of half of the specimens of each species, while taking steps to stop any of it reaching the soil. After this, though the dust-dosed maize continued to suffer from phosphorus deficiency, the wheat and chickpea plants perked up and grew to more than double the size of their undusted lab-mates. What is more, these species were clearly ready for the dust’s arrival. As soon as a lack of phosphorus announced itself, two things happened. Their leaves became hairier, and therefore better at capturing dust. And those leaves also started secreting acid fluids that could dissolve any incoming apatite, assisting phosphorus’s absorption..."

Free access: 15 March 2021, wiley.com: Direct foliar uptake of phosphorus from desert dust, backup Citat: "...Foliar dust doubled the growth of P-deficient chickpea and wheat, crops originating near the Syrian Desert. P deficiency stimulated several leaf modifications that enabled acquisition of up to 30% of the sparingly soluble dust-P that is conventionally perceived as unavailable. These modifications increased foliar dust capture, acidified the leaf surface and, in chickpea, enhanced exudation of P-solubilizing organic acids. Maize (originating far from deserts) displayed only a marginal response to dust..."
