2.2.3 Nanoscale Films and Host Materials
This category contains fertilizers and supplements that are encapsulated by nano-
scale films or held in nanoscale pores or spaces within a host material. Clays finding
applications in fertilizer products include those such as kaolinites, smectites,
halloysites, and palygorskites. These vary in terms of their chemical composition,
as well as their properties, such as surface area and surface charge. Nanoclays
generally are used in other applications as supportive filling agents to form
