Assessment of Available Macro and Micro Nutrients under Sugarcane – Wheat Cropping Sequence in Different Location of Meerut and Bulandshahr Districts of Uttar Pradesh

The organic matter content in the soil influences almost all the component of soil which influences the crop productivity. Macro nutrient (N, P and K) and micronutrients (Cu, Fe, Mn and Zn) are important soil elements that control its fertility. The soil samples of 0–15, 15–30 and 30–45 cm depth were collected from four different locations of Meerut and Bulandshar districts under sugarcane (R)–wheat cropping sequence. The soil samples were analyzed for physico – chemical properties using standard procedure for pH and electrical conductivity, organic carbon, available nitrogen, available phosphorus, available potassium by the ammonium acetate method and available micronutrients (Fe, Mn, Zn and Cu) in soil samples with extracted by diethylene triamine penta acetic acid (DTPA) solution (0.005M) DTPA + 0.01M CaCl₂ +0.1M triethanolamine, pH 7.3. The study revealed that the soils were normal to moderately alkaline in reaction, low to medium in organic carbon, low in available nitrogen, low to medium in available phosphorus and potassium and in general sufficient in available Cu, Fe, Mn and Zn at surface soil. Correlation values revealed that soil pH has a negative correlation with Fe (r = 0.487) and Zn (r = - 0.265) and significant and negative correlation with Mn (r = - 0.679^*) whereas it was positively correlated with Cu (r = 0.327). CEC of soil was negatively correlated with sand (r = - 0.560) and silt (r = - 0.140) and positively and highly significantly with clay (r = 0.897^**). Available soil nitrogen was significantly and positively correlated with total N (r = 0.509^*) and microbial biomass carbon (r = 0.605^*).
