A field experiment was conducted during kharif, 2019 at Anand Agricultural University, Anand, Gujarat, India. The effect of nutrient management practices on soil pH, cation exchange capacity, DTPA micronutrient and their inter relationship were studied. The result of present study showed that relationship between available micronutrients and soil pH was significantly and negatively correlated for DPTA Fe, Mn and Zn. In case of DTPA Cu and soil pH relationship was positively correlated. The highest R2 value for the relationship between DTPA micronutrients and soil pH was for the available Fe (0 79). The relationship between available micronutrients and cation exchange capacity of soil was reverse of soil pH. Available Fe, Mn and Zn were positively correlated with cation exchange capacity and reverse for DTPA Cu. The lowest R2 value for relationship between DTPA micronutrients and soil cation exchange capacity was for DTPA Cu (0.008).
