1. Does Inoculant or Sulfur Improve Nitrogen Fixation in Soybean After Long-term Corn?

This study evaluated the effects on nutritional dynamics and productivity in soybean, focusing on nitrogen and sulfur management in fields with more than twelve years of continuous corn in the state of Indiana (USA). Continuous corn systems are known to alter soil microbial activity, leading to a reduction in the nitrogen-fixing bacteria population, which affects the biological nitrogen fixation process in legumes, such as soybeans, which rely on those bacteria to meet their nitrogen requirements...
