Light structures phototroph, bacterial and fungal communities at the soil surface [PDF]

, 2013
The upper few millimeters of soil harbour photosynthetic microbial communities that are structurally distinct from those of underlying bulk soil due to the presence of light. Previous studies in arid zones have demonstrated functional importance of these

Soil characteristics and tillage can predict the effect of 'structure lime' on soil aggregate stability [PDF]

, 2022
Context. In Sweden, mixtures of 80-85% ground limestone and 15-20% slaked lime (hereafter, 'structure lime') are used in subsidised environmental schemes to improve aggregate stability and mitigate phosphorus losses on clay soils. Aims.
