In the paper the balance of nitrogen in 100 selected farms of Rozdrażew community is presented. Results concern: livestock density, production of nitrogen in animal organic fertilizers, balance of nitrogen in farms as well as for cultivated plants. Production of nitrogen in animal organic fertilizers and its balance were compared to regulation being in force in Poland. It was stated that in examined farms livestock density was high (in 72.0% of farms over 1 large livestock unit) and in four farms production of nitrogen in animal organic fertilizers was larger than allowed amount of 170 kg per 1 ha of agriculturally utilized area. In 55 farms (55.0% of total farms) the surplus balance difference of nitrogen (brought in organic and mineral fertilizers minus uptake in yields of plants) was larger than allowed 30 kg/ha of UAA. Among cultivated plants in examined farms the highest surplus balance value of nitrogen was stated in case of winter wheat, winter barley, grain and silage maize, fodder beet, winter rape and forage grasses.
