Investigating the Effect of a Mixed Mycorrhizal Inoculum on the Productivity of Biomass Plantation Willows Grown on Marginal Farm Land

摘要: Inoculation with mycorrhizal fungi, proven mediators of soil fertility, has great potential in agricultural and silvicultural systems. This is particularly true short-rotation coppices (SRCs), where questions food displacement fertilization are causes concern for researchers policy makers. We set out to thoroughly test if current inoculation methods, coupled reduced fertilization, can demonstrate a growth benefit SRC willows on marginal lands. Roughly 21,600 Salix miyabeana Seeman (‘SX61’ ‘SX64’) were planted hierarchical design treatments randomized first, cultivars second, third. process was repeated across three fields different type (which, our experiment, given the descriptive names Sandy, Rocky, Dry). The inoculum species, Rhizoglomus irregulare Blaszk., Wubet, Renker & Buscot Sieverd., G.A. Silva Oehl Hebeloma longicaudum (Pers.) P. Kumm., chosen as they most likely be commercially available, because represent both arbuscular ectomycorrhizal types. Growth measured over 2.5 years, or growing seasons. Fertilization treatment (75 kg/ha Nitrogen), however, only applied during second season. Our results conclusively showed no from that exhibited significantly rates, well significant differentiation fertilization.
