The nano-lime and nano-dolomite had the surface areas of 1000 and 900 m2 g -1 , respectively, which are nearly 10 times higher than their respective conventional counter parts. Nano-liming is more effective due to the extensive surface areas of these materials that had increased by ten times which correspondingly increased the exchange properties. As a result of eluviations of acidity producing cations, the Ca and Mg added through the liming materials got adsorbed that closely coincided with a set of favourable changes in soil properties. The changes in soil properties had reflected on the yield and quality of crops grown in either hilly or plain acidic soils. The data have unequivocally suggests that nano-liming may be one of the plausible strategies to improve the liming efficiencies. There are several stages of testing of the nano-materials for their biosafety prior to use in the open field conditions. It is one of the early lead indicating improved liming efficiencies through nanotechnological approaches. | Impact of nano-liming materials on biological properties of acid soils
