Absotively on the dot!
However, the surface area of the Sahara desert is 9.2 Million square kilometers and a minute fraction of it, only, is necessary to engender a phenomenal response to the world's food needs.
On the other hand, if the process is actually used to combat desertification on a much larger scale, I don't think it will find enough enthusiasts to undertake projects at a scale likely to influence the dust supply to the amazon forest.
I believe, that this development would be useful, for agricultural purposes, to some Saharan and sub-Saharan countries suffering from desertification if it is applied in regions where a reasonable water supply for the production of these liquid nanoclays and for subsequent irrigation is available which is not the case for most sub-Saharan countries regardless of the economies of water generated by this process.
Furthermore, the current costs of production of these liquid nanoclays, in part, related to the consumption of fresh water during the production process are prohibitive. Economies of scale may reduce such costs if further mechanization is applied; which will shift the costs from losses of water by evaporation (desert) to more substantial investments upfront.
Also, one has to keep in mind that the Sahara desert is a planetary phenomenon related to the recession of the earth axis, which, all conditions put together, will see to it that it remains a desert for a couple thousand years more. In the long term, ongoing "climate change" may prove me wrong "may".
Finally, in addition to the availability of water one must note that the Sahara desert is a dynamic phenomenon. So, keeping the sand out of the agricultural patches is more of a concern than the availability of arable land, water and the economics thereof.
So, one need not worry, at no time, about the dust supply to the Amazon forest but rather about the frenetic deforestation underway for the industrial production of cooking oils, sugar, bio-fuels and red meat.
