The future of agricultural production involves sustainable systems with a balance between nutrients in soil–plant systems. These are based on limiting the use mineral fertilizers while introducing natural sources that increase soil fertility. best example such system is plant rotation, including legumes as forecrop for cereal plants. For this reason, goal present study was to determine possibility obtaining nitrogen from air using 15N isotopes and quantity biologically fixed taken up by winter wheat cultivated succeeding plant. In field experiments, we investigated cycle legume plants rotation under conditions, follows: soybean–winter wheat–winter wheat. After soybean seedling emergence, fertilizer (15NH4)2SO4 containing 20.1 at% (a dose 30 kg∙ha−1) applied, summer reference yield reached 2.48 t∙ha−1 seeds 8.73 crop residue (CR), providing total 11.21 t∙ha−1. biomass contained 149.1 kg∙ha−1 nitrogen, 108.1 41.0 residue, which 34.0 11.4 fixed.
