Limited information has been published regarding the attenuation ofmicroorganism, specifically amoeba in soil with biochar amendment. This studydetermines the attenuation of amoeba between water-saturated clay and sandysoil with biochar and to determine the effect of biochar in clayey and sandy soilwith amoeba contamination in relation to its transport. Four treatments wereformulated, TS (sandy soil, control), TSB (sandy soil + biochar), TC (clayeysoil, control) and TCB (clayey soil + biochar) and replicated three times. Theexperiment was rendered using a 17cm soil column with 2.5cm diameter;all treatments were saturated and leached. Number of amoeba leached andattenuated was counted under a compound microscope. Results revealed thatclayey soil attenuated more amoeba compared to sandy soil treatment due toits smaller pores. Moreover, biochar amendment in a sandy soil would enhance the attenuation of amoeba and lessen the transport of amoeba while biochar amendment in clayey soil lessens the attenuation and facilitate the transfer ofamoeba. It has also been observed that at four to eight centimeters depth of thesoil column, the spatial distribution of amoeba is superior. The study implies thatbiochar physical enhancement of soil would depend upon the initial texture ofthe soil.'
