	MICROCOSM STUDIES FOR THE BIODEGRADATION OF CARBARYL IN SOIL TATHEER ALAM NAQVI^1, NISAR AHMED KANHAR², ABDUL HUSSAIN SHAR²,MASROOR HUSSAIN³ AND SAFIA AHMED³ Abstract:* A field-scale experiment with a complete randomized block design was performed to study the degradation of carbaryl in soil. Soil was treated with different types of treatments. Degradation was observed at two levels of soil after 7, 14 and 21 days of treatments. Soil bacteria have significant effect on the degradation of carbaryl in soil. Nutrient additions stimulate the biodegradation of carbaryl and the rate of degradation of carbaryl increase with respect to number of days of treatment. It has been found that after 21 days 85% carbaryl has been degraded from soil treated with nitrogen source. ¹Departmet of Environmental Sciences, Karakoram International University, Gilgit ²Department of Microbiology, Shah Abdul Latif University, Khairpur, Sindh, Pakistan ³Department of Microbiology, Quaid-i-Azam University, Islamabad, Pakistan ^Corresponding author E-mail: statheer_2000@hotmail.com*
