Abstract
The multi-layered sand assembly comprising neat sand, super-hydrophilic and super-hydrophobic sands for feasible and sustainable desert agriculture is described. The ingredients such as PAM used in the super-hydrophilic sand layer and the PS-PMMA/DVB polymer for the super-hydrophobic layer are relatively less expensive and thus the overall development of the coated sand is economical and cost effective for the mass production of modified sand layers. The tandem action of high water absorption and retention over time by super-hydrophilic sand layer and high water repulsion to avoid water loss by super-hydrophobic sand of the proposed assembly would make the achievable agriculture in desert lands.
