In this paper we introduce green synthesis of Silver Nanoparticle.The biological method of nanoparticle synthesis is a relatively simple, cheap, and environmentally friendly method than the conventional chemical method of synthesis. Silver nanoparticles (AgNPs) are one of the most vital and fascinating nanomaterials among several metallic nanoparticles that are involved in biomedical applications. Here silver nanoparticles were synthesized using Thujaoccidentalisplant leaf extract. The leaf extract acts as both reducing and capping agent. The synthesized silver nanoparticles were confirmed by the change of colour after addition of leaf extract into the Silver Nitrate solution. Morphological studies were performed using scanning electron microscopy (SEM) and the elemental composition was determined using energy dispersive X-ray analysis. The biosynthesized Silver NPs were characterized by using UV-Vis analysis, Fourier Transform Infrared analysis (FTIR), X-ray diffraction analysis (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray analysis (EDX). The synthesized Silver NPs were in cubical structure with the average particle size in the range between 50-60nm.In soil activity tests it was found that the sample (soil) show 6.757 which indicates the soil is slightly acid.The Electrical conductivity of sample (ms/cm) 0.567 Which indicates the soil have strongly saline, only tolerant crops yield satisfactorily..
