Abstract:

Soil fertility mapping with specific reference to micronutrients and sulphur was carried out by analyzing 576 geo-referenced soils collected from 64 mandals of Chittoor district of Andhra Pradesh. The available phosphorus content was found to be in the range of 11 to 239 kg ha-1 and indicated that their fertility class was medium and high in 21 and 79 per cent soils, respectively. The Nutrient Index (NI) value for available phosphorus (2.66) indicated that it was high. Potassium availability was found to be low in 4, medium in 42 and high in 54 per cent of soils of Chittoor with a NI value of 2.49 (high). The sulphur deficiency in the district’s soils was found to be 18 per cent and boron in 21% samples. The NI values for sulphur in soils of Chittoor district was found to be 2.54 (high) and 2.24 (medium) for B. All the thematic maps related to studied micronutrients and sulphur were prepared in GIS environment and presented.
