Abstract
It was done the field experiment on local organic fertilizer application in the different 3 year crop potations consisting wheat and potato, the main agricultural crop of Mongolia. The estimation of nutrient balance in the rotations with organic fertilizer application show that application of organic fertilizer has positively influenced to balanced nutrition content of soil. The loss of main nutritional elements such as Nitrogen, Phosphorus and Potassium was lesser in fertilizer applied case with fallow-potato-wheat rotation.
