One of the most important aspects of scientific crop productions is nutrient management. The knowledge regarding crop nutrition through nutrient management is of prime concern in modern agriculture. The findings of this paper will helpful in understanding the views of active investigators, theoreticians and practitioners on soil health. The research work was carried out in Agricultural College Farm, Bapatla using sweet corn hybrid Mahy-301 as a test crop. The experiment was laid out in completely randomized block design and were replicated thrice. The results on physical and physico - chemical properties of soil viz., WHC, pH, EC and OC revealed the non-significant influence of treatments during the crop growth. However, superior values were observed in the treatments which received organic sources of nutrients. The available N, P, K and sulphur status were significantly influenced whereas micronutrients except iron were not significantly influenced by the imposed treatments at both the stages i.e., Tasseling and Harvest of crop growth
