Abstract:

The soils of Chittoor district was found to be suffering from one or other or combination of two or more micronutrients in 324 out of analysed 576 samples and constituted 56 per cent (Zn alone in 103, Fe in 40, B in 60, Mn in 5, Cu in 5 and multi micronutrient deficiencies in 107 samples). Among individual nutrients, the soils of Chittoor were found to be deficient in available zinc to an extent of 33 per cent and boron in 21% samples. The iron deficiency in the district was found to be 19 per cent followed by copper in 4 and manganese in 2.6 per cent of samples. The sulphur deficiency in the district’s soils was found to be 18 per cent. The NI values for different micronutrients and sulphur in soils of Chittoor district was found to be 1.77 (medium) for Zn, 2.24 (medium) for B, 2.26 (medium) for Fe, 2.74 (high) for Cu, 2.82 (high) for Mn and 2.54 (high) for S. The correlation coefficients were worked out for various parameters studied in the investigation. All the thematic maps related to studied micronutrients and sulphur were prepared in GIS environment and presented.
