The present study was undertaken to assess the soil fertility status under sugar cane – sugarcane cropping system in different mandals of Visakhapatnam district of Andhra Pradesh. Seven mandals namely Munagapaka, Devarapalli, Chodavaram, Payakaraopeta, Yellamanchili, Rambilli and Ravikamatham were selected based on the area under sugarcane-sugarcane cropping system. The soil sample was taken from 0-15 cm depth with the help of augur and physical & chemical properties of the soil were analyzed. The organic carbon content in the soil of the district revealed that 25.38 per cent samples were less than 0.5, 71.07 per cent samples were ranged between 0.5 to 0.75 per cent and 3.15 per cent samples were more than 0.75 per cent. The nitrogen content in soil indicated that soils were low in nitrogen. 64.82 per cent samples were less than 280 kg /ha, 35.18 per cent samples were ranged between 280 to 560 kg/ha and no sample was found more than 560 kg/ha. In case of available phosphorus 3.1 per cent samples were less than 22 kg/ha, 66.5 per cent samples ranged between 22 to 56 kg/ ha and 30.4 per cent samples were more than 56 kg/ ha. Regarding potassium content, 72.40 per cent samples ranged between 108 to 280 kg/ ha, only 25.0 per cent samples were found more than 280 kg/ha and 2.60 per cent samples were found less than 108 kg/ha. All the four cationic micronutrients are above the critical limits except zinc, which is low in only in 5% samples in selected sugarcane growing soils of Visakhapatnam district, Andhra Pradesh.
