利用微生物指标评估土壤健康的兴趣日益增加,提出了精细尺度异质性如何影响微生物群落测量的问题。在这里,我们分析了17个牧场100多个土壤样本的细菌和真菌群落,并评估了不同尺度下的β多样性。我们发现,在同一农田的不同地点之间,微生物群落的差异很大,如果使用艾奇逊距离,我们发现,农田内的差异与农场之间的差异一样高。然而,如果使用Bray-Curtis或Jaccard距离,这种差异可以部分解释为土壤pH值和植被的差异,并且在真菌的暴民放牧下更高。因此,微生物群落的田间尺度变化会影响土壤健康评价。
Increasing interest in the use of microbial metrics to evaluate soil health raises the issue of how fine-scale heterogeneity can affect microbial community measurements. Here we analyse bacterial and fungal communities of over 100 soil samples across 17 pasture farms and evaluate beta diversity at different scales. We find large variation in microbial communities between different points in the same field, and if Aitchison distance is used we find that within-field variation is as high as between-farm variation. However, if Bray-Curtis or Jaccard distance are used this variation is partially explained by differences in soil pH and vegetation and is higher under mob grazing for fungi. Hence, field scale variation in microbial communities can impact the evaluation of soil health.
