In comparison with other legumes and grasses, white clover provides forage with high nutritional value and quality. A field experiment was conducted by growing three indigenous and three exotic ecotypes of white clover in the mountain region of Himalayan i.e. the State of Azad Jammu and Kashmir, Pakistan. Plant nutrient content of N, P, K, Ca, Mg, Fe, Mn, Cu and Zn were determined in the forage of white clover while soil nutrient content of N, C, P, K, Ca and Mg were determined in the soil under white clover. Pure grass and soil without white clover were used as control/check. Mineral nutrient contents in white clover were substantially higher than those found in the grass. Among macronutrients, the content of P and K were 0.32 and 1.96%, while the contents of N, Ca and Mg were 2.61, 1.10 and 0.29%, 2-3 fold to the content found in the grass. Micronutrients also showed similar trend and the concentration of Fe, Mn, Cu and Zn were 192, 86, 31 and 49 mg per kg, almost double t
