The soil fertility data with specific reference to micronutrients was carried out by analyzing 1000 soil samples from 6 mandals of Chittoor district of Andhra Pradesh. The average percentage deficiency of the nutrients for 6 mandals (Tirupati(R)&(U), Chandragiri, Renigunta, Pakala and Pulicherla) was found to be SULPHUR- 9.76%, ZINC- 19.63%, IRON- 25.96%, MANGANESE- 8.62%, COPPER- 0% and BORON- 8.14%. The maximum Sulphur and Manganese deficiency were found in Tirupati(U) of about 16.33 & 12.24%. The maximum Zinc and Boron of about 23.45 & 14.53% were found in Chandragiri, whereas the maximum deficiency of Iron was found to be 41.30% in Tirupati(R). The Copper content in 6 different mandals of Andhra Pradesh was found to be 0%.
