An article is focused on fertilization management in farms with different specialization of production. Nitrogen, phosphorus, and potassium nutrients balances were analysed. An average amount of nutrients and final balance are shown in graphs in detail. Average amount is calculated as an input of nutrients on one hectare of arable soil during one calendar year. The balance shows the result value of nutrients in soil in the end of vegetation period. Crop farms dispose only with a limited number of animals and, therefore, they are focused on production crops with a limited part of forage crops. This farms usually use mineral fertilization. Milk production farms utilize mineral as well as organic fertilization. They combine production and forage crops. Farms specialized in cattle, sheep and goat production are characterized by large pasture and forage crops areas with high ratio of legumes, which impact the value of fertilization calculated per arable soil. Farms with mixed production balance crop and animal production which result in combination of mineral and organic fertilization. Production and forage crops are more balanced in this type of farms, as well as the fertilization management.
