Soybean is an important crop in sustainable agriculture practice throughsymbiotic nitrogen fixation. A leguminous soybean, biologically linked nitrogen isa great source of agriculture and an important alternative to the reduction ofnitrogen fertilizer use to eliminate the problem of environmental pollution. Itcarries out the nitrogen fixation with the nodules formed with the bacteria(Bradyrhizobium japonicum) in the roots. Soybean crop rotation has been used formany years to improve soil productivity. But in the last years global climate changewhich causes amongst other things high temperature affects crop yield und qualityand sustainability of agriculture. High temperatures (30 °C and above) have beenreported to cause significant decreases in dry weight and nitrogenase activity. Inaddition, irregularities in the precipitation regime and water in the summer periodhas a negative effect on plant growth and nitrogen fixation and thus on soil fertility.Many factors such as temperature, soil moisture, high pH level, salinity andnutrient deficiency affect on the amount of biologically bound nitrogen and fixationdecrease depending on these factors. The response of the plant to these factorsvaries according to the nutrients, water demand in critical plant developmentstages. Under stress conditions the knowledge of how these factors affectingnitrogen fixation is an important issue for food safety and production. In this work;the effects of nitrogen fixation potential and the factors affecting have beeninvestigated also it is aimed to have research cooperation with other institutes touse soybean cultivation more effectively in sustainable agriculture in Turkey.Soybean is an important crop in sustainable agriculture practice throughsymbiotic nitrogen fixation.
