“…production on a clay-loam soil in China. However, Janniche et al [14] reported measured H across treatments in agriculturally affected groundwater (2.97 to 3.04) which was within the range measured in this study. Averaged across yield area, H and E H were greater (p < 0.05; Figure 2) in Region 7 than in all other regions.…”

Microbial Carbon Substrate Utilization Differences among High- and Average-Yield Soybean Areas

Abstract:Since soybean (Glycine max L. (Merr.)) yields greater than 6719 kg ha −1 have only recently and infrequently been achieved, little is known about the soil microbiological environment related to high-yield soybean production. Soil microbiological properties are often overlooked when assessing agronomic practices for optimal production. Therefore, a greater understanding is needed regarding how soil biological properties may differ between high-and average-yielding areas within fields. The objectives of this study were to (i) evaluate the effects of region on soil microbial carbon substrate utilization differences between high-(HY) and average-yield (AY) areas and (ii) assess the effect of yield area on selected microbiological property differences. Replicate soil samples were collected from the 0-10 cm depth from yield-contest-entered fields in close proximity that had both a HY and an AY area. Samples were collected immediately prior to or just after soybean harvest in 2014 and 2015 from each of seven geographic regions within Arkansas. Averaged across yield area, community-level carbon substrate utilization and Shannon's and Simpson's functional diversity and evenness were greater (p < 0.05) in Region 7 than all other regions. Averaged across regions, Shannon's functional diversity and evenness were greater (p < 0.05) in HY than in AY areas. Principal component analysis demonstrated that a greater variety of carbon substrates were used in HY than AY areas. These results may help producers understand the soil microbiological environment in their own fields that contribute to or hinder achieving high-yielding soybeans; however, additional parameters may need to be assessed for a more comprehensive understanding of the soil environment that is associated with high-yielding soybean.

“…Shannon's diversity index mathematically weights rare species (i.e., substrate utilization) more than common ones, while Simpson's diversity index mathematically weights common species more and rarer species relatively less [14]. Therefore, the two diversity indices are not meant to be equivalent in magnitude.…”

“…CLPP has numerous advantages over other molecular and non-molecular techniques since it is relatively rapid, without specialized expertise requirements, and allows functional community characterization (Weber and Legge, 2009). Microbial functional diversity has been studied recently in soils amended with dairy sewage sludge (Frac et al, 2012), native and post-mining rehabilitation forest (Banning et al, 2012), ground water polluted agricultural soils (Janniche et al, 2012), sandy loam soil affected by long term application of organic amendments and mineral fertilizers (Hu et al, 2010).…”

“…Changes can improve or worsen the soil's quality and health, being the first, the capacity of the soil to function productively, under management or natural conditions, supporting human wellbeing (USDA 2002;Janniche et al 2012), while health is the capacity to sustain its functions over time as a vital living ecosystem (USDA 2015). Thus, assessment of the quality and health of a soil involves the analysis of several physicochemical and biological processes and their interactions through space and time (Rahmanipour et al 2014).…”
