Future research should focus on long-term monitoring to assess whether higher plant species richness enhances soil multifunctionality, microbial diversity and SOC persistence over time.

Quantitative insights into soil microbial communities in shelterbelt agroforestry systems (2026) · Agroforestry Systems · doi
Soil microorganisms are sensitive to environmental conditions. The choice of soil sampling depth can strongly influence results. There is a lack of quantitative insights into the effects of shelterbelts on soil microorganisms.

Further studies are needed to evaluate the impact of sampling design on soil microbial diversity estimates in different ecosystems. The development of new sampling designs and methods for characterizing soil microbial diversity is needed. The use of individual cores and physically homogenized composite samples should be compared in different soil types and ecosystems.

The impact of sampling design on soil microbial diversity estimates is not well understood. The effects of physical homogenization on diversity estimates are not well characterized. There is a need for a framework to evaluate the impact of sampling design on soil microbial diversity estimates.
