A Kristian in Norway founded Desert Control. See site by that name. The patented clay spray allows sands to retain water and carbon helping food crops and trees to do the same. Fascinating Ted Talks and YouTubes.
Like ag-usa.net, part of the sand to soil alchemy is microbes and fungi. Ironically; desert control is a father/son Christian duo like ag-usa.net.
Desert control field tests in several countries documents crops and trees faster in actual desert climates and so astonishingly; some refuse to believe the results. This is what we mean by super science allowing nature to magnify our climate correction campaigns in any country. Imagine how desert would do with fairly good soil! Imagine their product in Ghana with ag-usa.net?? We see what can be.
