Biomass data of early and mid successioinal plant species in monoculture and mixture as influenced by plant-soil feedback

Data were collected in the greenhouse two-stage (conditioining & feedback) biodiversity experiment in Wageningen, the Netherlands. Abbreviated headlines are as follows: "stage"=succession stage;"species"=plant species (including ten early succesional plant species and ten mid successional plant species);"soil"including conditioned soil and unconditioned soil;"monoculture"=biomass production in monoculture(g pot-1);"mixture1""=biomass production in plant community assemblage1(g pot-1);"mixture2""=biomass production in plant community assemblage2(g pot-1);"mixture3""=biomass production in plant community assemblage3(g pot-1);"mixture4""=biomass production in plant community assemblage4(g pot-1);"mixture5""=biomass production in plant community assemblage5(g pot-1).
