Abstract
A soil resource inventory was conducted at village level in the Melur block of Madurai district, Tamil Nadu to assess the micronutrients status in the soils and to prepare fertility maps depicting the extent of soil micronutrient deficiency/sufficiency using GIS and GPS techniques. Soil samples were collected at revenue village wise along with geo coordinates and analysed for available micronutrients such as Zn, Fe, Cu and Mn by adopting standard procedures. Based on the nutrient status, the soils were grouped as deficient or sufficient using the critical limits. Per cent deficiency of micronutrients in Melur block was worked out and the thematic maps showing status of different available micronutrients were generated. The results indicated that, Fe and Zn deficiency is most prevalent in the soils of Melur block in Madurai district to an extent of more than 35 per cent, followed by Cu (1.1%) and Mn (10%).
