Sown biodiverse pastures consist of diverse mixes of up to twenty different species or varieties of seeds, and are rich in legumes.
The mixes of sown species are often enriched with seeds from spontaneous plants such as Plantago spp., Vulpia spp.
The higher plant productivity of SBP implies increased atmospheric carbon capture through photosynthesis.
Part of the biomass produced is stored in soils due to the high density of yearly renewed roots.
SOM pools are also increased by leaves’ senescence, and by animals returning undigested fibre to the soil.
