由于 2008 年生长季节美国中西部的湿度增加和洪水泛滥，一些大豆 [Glycine max (L.) Merr.] 种植者对 2009 年土壤根瘤菌 (Bradyrhizobium sp.) 的生存能力感到担忧。在之前被洪水淹没较长时间的土地上建立了三个田间试验，以测试根瘤菌接种剂的性能以及种子产量和质量对初始土壤的反应。根瘤菌种群。种子产量和含油量对不同地点的根瘤菌接种剂没有反应（分别为 P = 0.39 和 0.70），而种子蛋白质含量的反应因接种剂而异（P = 0.006）。产量（P = 0.01，R 2 = 0.10）和蛋白质（<0.001，R 2 = 0.36）含量与初始根瘤菌种群呈负相关。种子含油量与初始根瘤菌种群呈正相关（P = 0.009，R 2 = 0.10）。结果表明，初始土壤根瘤菌种群足以实现作物的最佳生长，并且在这些环境中不需要添加根瘤菌接种剂。
Due to increased moisture and flooding in the midwestern United States during the 2008 growing season, some soybean [Glycine max (L.) Merr.] growers were concerned about the viability of soil rhizobia (Bradyrhizobium sp.) in 2009. Three field experiments were established on land, which had previously been flooded for an extended period of time, to test the performance of rhizobia inoculants and the seed yield and quality response to the initial soil rhizobia population. Seed yield and oil content did not respond to rhizobia inoculants across locations (P = 0.39 and 0.70, respectively), whereas seed protein content response differed among inoculants (P = 0.006). Yield (P = 0.01, R 2 = 0.10) and protein (<0.001, R 2 = 0.36) content were negatively correlated with the initial rhizobia population. Seed oil content was positively correlated with the initial rhizobia population (P = 0.009, R 2 = 0.10). Results suggest that initial soil rhizobia populations were adequate for optimum crop growth and the addition of a rhizobia inoculant was not required in these environments.
