WebRivier et al. (2024) confirmed that compost addition to sandy and loam soils affected pore-size distribution, increased water holding capacity and reduced bulk density in their pot-plant experiments. They also observed a significant increase in the stability of 1–2 mm aggregates when they applied organic fertiliser to sandy soil.
