The study was carried out to analyse plant nutrient elements present in soil samples from different part of Pokhara metropolitan city and to compare them with standard recommended values. The plant nutrient elements of soil samples nitrogen, phosphorus, potash, zinc, iron, copper, and boron were analyzed by using specific techniques. The PH was analysed by PH meter, organic matter by gravimetric method, nitrogen by Kjeldal method and phosphorus by Olsen’s method (1954) of analysis. Similarly, the amount of zinc, iron and copper were determined by chemical method, potassium by flame photometer method, and boron by using a spectrophotometer. The essential macronutrients nitrogen, phosphorus and potash remained within the permissible limit for most of the samples. The essential micronutrients zinc, copper and boron in four samples were within the acceptable range. The content of iron was higher than that required as an essential crop nutrient. The observed values of plant nutrient elements expressed that the sampling area could be used for agricultural cultivation and production.

Nutrient elements, one of the major factors shaping plant development, are the major components of plants, and, after being taken from the soil, they are present in different organs of plant at different concentrations. The speciation of nutrient elements within plant body is vital importance for determining the contribution to plant development, knowing the transfer between organs within the body of organs, clearly understanding the factors influencing plant development, and shaping the plant development. In the present study, the change of the concentrations of K and Mg (macronutrient elements) and Cu (micronutrient elements) by species and organ in woody species Prunus cerasifera, Platanus orientalis, Acer negundo, Fraxinus excelsior, Catalpa bignonioides, Aesculus hippocastanum, and Tilia platypyllos. As a result, it was found that the changes of elements by species were statistically significant in all the organs, and, in general, the highest concentrations were observed in leaves. The study results revealed that the concentrations of these elements might significantly vary between the organs in the same species, which varies significantly by the species.
