Biopores have been shown to be enriched with plant available nutrients as compared to the surrounding bulk soil and therefore are considered hot spots for the nutrient acquisition especially in the otherwise nutrient-poor subsoil. As a result of colonization of biopores by earthworms, pore walls are enriched with nutrients. In this study, a first attempt was made to assess the influence of earthworm abundance on both structural pore wall characteristics as assessed with in situ endoscopy and on pore wall C and N contents. Higher earthworm density resulted in higher N contents and significantly higher C contents in biopore walls as compared to the surrounding bulk soil, regardless whether they showed visible earthworm coatings. In the treatment with lower... |
