THE EFFECTS OF RHIZOBIUM ON SOYBEAN GROWTH, IN POOR, AND RICH NITROGEN SOIL. INTRODUCTION The meaning of this experiment was to test the three hypotheses, when planted in a nitrogen poor soil, soybeans will grow larger if their roots are infected with the nitrogen fixing bacteria, Rhizobium. Also if planted in a nitrogen rich soil, soybeans will resist becoming infected by Rhizobium. Lastly, if planted in a nitrogen rich soil, than soybeans that do become …showed first 75 words of 1425 total…

This was only slightly smaller than the class average of 1.756 grams per plant for the soybean plants planted in high nitrogen soil without Rhizobium (-H). I believe this was caused by extremely high levels of nitrogen, which depressed growth in the soybean plant. LITERATURE CITED Introduction paraphrased from; Wolfe, Andrea.
