Present exploration aspired to produce biochar from rice husk basic nano particles using slow pyrolysis technique. The physio-chemical characteristics, phases and surface morphology of biochar were studied by different visual techniques. The obtained result confirmed that rice husk derive biochar is considered as a novel carrier of nano nutrients and advanta-geous microorganisms. The recorded values of mean radius, nearest distance between particles, perimeter of particles, the surface area of biochar basic nano particles, cation and anion exchange capacity were examined. The image of surface topography showed that biochar enrich by nano-particles with “sponge” shaped structures and nano-particles were imbedded into macro, meso, and micro pores of biochar. The spacemen atoms of pure elements composition of biochar followed the descending order of oxygen > silicon > sodium > potassium > carbon > magnesium > calcium > alumina. The stability and fertility of biochar basic nano particles might be used as safety soil amendment, climate changes mitigation, source of fertilizer and eco-friendly. The determined conductivity of the prepared biochar is found in the range of semiconductors which make it suitable and prom-ising material to be used as filler in polymer composites and nano composites for many electric and electronic applications. © 2020, Agricultural Academy, Bulgaria.
