What is Aruba's soil?

Aruba generally has poor soil. The northern side of the island is rocky. There's red clay soil on much of the rest of Aruba. Its ability to retain water has been responsible for the success of Aruba's oldest company, Aruba Aloe Balm N.V. The company's aloe vera flourishes in the poor soil. But Aruba's soil is now being enriched with Fluff, a byproduct of the WastAway hydrothermal process that transforms household garbage into a topsoil supplement.
