Impact of mycorrhizal fungi and nematodes on growth of Andropogon gerardii Vit., soil microbial components and soil aggregation
… (52×32×40cm) were planted to Andropogon gerardii Vit. so that a third of the microcosms could be destructively sampled at the end of each growing season for three years. Plant biomass was separated into aboveground, rhizomes, and roots. All components were dried and weighed at harvest. Mycorrhizal …
