Soil plays a critical role in determining the food nutrition at base of chain, which makes it essential for safety. This study demonstrates how micronutrient deficiencies and pollution from hazardous elements may affect crop productivity as well human animal health. In Kashmir valley's Bandipora-Ganderbal region, 200 top soils were examined to ascertain toxicity risks trace element deficiencies. With mean values 44,759 ± 6072, 120 23, 114 18, 89 22, 44 8, 33 7, 23 4, 19 11 5 respectively, concentrations (mg kg−1) vary Fe: 31,326 77,420, Cr: 59 228, V: 79 235, Zn: 30 174, Ni: 18 79, Cu: 10 59, Pb: 15 55, Co: 38 As: 1 36. A portion area has levels As, Cr, Ni, V is deficient Cu, Zn agricultural production. Micronutrient are associated carbonate rock topography, while symptoms linked areas with footprints. Weak correlations Pb, significant Fe, Co, indicate anthropogenic geogenic origins, respectively. For V, enrichment factor minimum; Zn, moderate. The soil indices low, those integrated toxic risk index was evaluated order gain better understanding research region. ranged 3.80 10.64, 5% samples having no risk, 63.5% low 31.5% moderate risk. Compared forest, grazing areas, waste land sites, used agriculture, habitation, hydroelectric projects more contaminated. main causes pesticides, fertilizers, construction, vehicle emissions. study's conclusions about help policymakers improve health higher yields healthier lifestyle.
