The interactions between nematode and microbial communities offer significant insights into the impact of organic amendments on the productivity of Miscanthus x giganteus cultivated on marginal lands

Original language description

The interactions between nematode and microbial communities offer significant insights into the impact of organic amendments on the productivity of Miscanthus x giganteus cultivated on marginal lands. Biosystems Diversity, 33(1), e2508. doi:10.15421/012508 The investigation is devoted to the analysis of the impact of organic fertilisers, in particular biochar derived from sewage sludge, on the productivity of the energy crop Miscanthus x giganteus and soil health on marginal lands. The results of long-term observations show that among organic additives, biochar demonstrates the most pronounced stabilising effect on the structure of the nematode community, although its impact on the total number of nematodes is limited. The application of biochar increased the diversity of trophic groups and modified the soil trophic network, which was dose-dependent. The experiment also revealed a significant impact of organic additives on the ecological indicators of nematode communities. In particular, the use of biochar significantly increased the Maturity Index (MI) and the Structural Index (SI), which indicates an improvement in the stability and complexity of the soil ecosystem. Reducing the number of migratory endoparasites and other plant-parasitic nematodes, such as Pratylenchus spp. was crucial in increasing the yield of M. x giganteus. The most pronounced changes were observed when biochar was applied at 10% (BD2). The field trial also assessed the impact of organic amendments on soil microbiological characteristics. Although the total number of bacteria and fungi did not change significantly, there was an increase in the number of Pseudomonas bacteria in the biochar-treated samples. This confirms the role of biochar as a stimulator of the growth of beneficial microorganisms and improvement of soil microbial activity. At the same time, the activity of dehydrogenase, which is an indicator of microbial activity, did not change significantly under the influence of additives. The test findings indicate that the addition of biochar has a beneficial effect on the yield of M. x giganteus, contributing to an increase in green mass at harvest. The impact of organic amendments was long-lasting, demonstrating the potential to increase the productivity of energy crops on marginal lands. Reducing the number of plant-parasitic nematodes, especially migratory endoparasites, was a key factor in improving yields. The outcomes of the study confirm the significance of an integrated approach to the application of organic amendments to improve soil health and increase the productivity of energy crops. The dose-dependent effects of biochar indicate the need to adapt application strategies to specific agroecosystems. Further research should focus on analysing the long-term effects of organic fertilisers on the functioning of trophic networks and microbiological processes in the soil.
