Linking Rhizosphere Soil Aggregates with Belowground and Aboveground Plant Traits

Rhizosphere soil ecosystems are represented by the diversity of different aggregate-size classes, such as large macroaggregates, small mesoaggregates, and microaggregates. Though these classes represent distinct biological, chemical, physical properties, little is known about their dynamics relationships with belowground aboveground plant traits. In this study, we examined various organic carbon contents many soybean Our study revealed several novel interesting between structural properties Notably, macroaggregates a major portion rhizosphere ecosystem plants while decreased decreasing size aggregates. Only microaggregates showed significant relationship root architectural traits, length surface area. Among all aggregate abundance were better correlated general, positive correlations leaf trichome density (defense traits) macronutrients, P, K, S contents; there mostly negative some micronutrient (Ca, Mn, Zn, Cu, B, Mg) roots shoots. However, positively mineral Collectively, trichomes (defense) physiological traits (micro-mineral contents) suggest significance in nutrition defense. our results further research needed to discern role mediating growth, development, defense, physiology.
