Abstract: Clay is a naturally occurring material composed primarily of fine grained minerals, which shows plasticity through a variable range of water content and which can be hardened when dried. Clay deposits are mostly composed of clay mineral (phyllosilicate mineral) and variable amount of water trapped in the minerals There are four main groups of clays i.e. Kaolinite, Montmorillonite (nano clay raw materials), illite and chlorite (Faheem uddin, 2008). Nano clay are minerals which have a high aspect ratio and with at least one dimension of the particle in the nanometer range.Impurities act as stress concentrators, resulting in poor impact and tensile properties (M. S. Nazir et al., 2016). Nano-clay polymer composite are potential agro-biotechnological applications for increase in input use efficiency especially fertilizer and water under abiotic stress condition. Improves water holding capacities and Nutrient release behaviour of nutrients (Raj Mukhopadhyay et al., 2014). Nano-clay finds various applications like treatment of improving soil health, drug delivery system etc. Application of nano fertilizers will drastically bring down the use of chemical fertilizer with improvement in the crop yield. Nano fertilizers will also improve the soil aggregation; moisture retention and carbon build up of the soil. The use of nanomaterials for delivery of pesticides and fertilizers is expected to reduce the dosage and ensure controlled slow delivery. Modification of clay particles with nanomaterials reduces the toxicity of soil by removing pollutants and heavy metals and thus its effects entering the food chain can be reduced.
