Fine root biomass (Bf, g DM m-2) and production (Pf, g DM m-2 d-1) were periodically measured in CC by the sequential coring and ingrowth core methods, respectively. In addition, sap flow was measured by a thermal dispersion method only in E2.

WebbRoot ingrowth cores were also used to monitor root biomass and root growth. The ingrowth core method was used according to Milchunas et al. [26]. It contains two cylinders of a geometric toroid shape when viewing the concentric cylinders from above the ground. The diameters of outer and inner cylinders were 17 cm and 11 cm, respectively. Webb29 mars 2016 · Here, we aim to determine the optimal methodology for utilizing ingrowth cores in estimating annual fine-root production (FRP) and its vertical distribution in trees, shrubs and herbs. Methods We used 3-year data obtained with modified ingrowth core method and tested two calculation methods: ‘ingrowth-dividing’ and ‘ingrowth …

After … Webb6 mars 2013 · The ingrowth cores were inserted in November so that measurements can be commenced in January. For filling the mesh bags, soil collected from the same plots was used after removing the roots through sieving. The root-free soil was filled through the plastic tube into the mesh bag.
Webb1 mars 2008 · To identify nutrient limitations within a lowland tropical rainforest we utilized an alternative method, the root ingrowth-core technique, which uses nutrient enriched substrates implanted into the forest soil. Over time root growth into the enriched substrates is greatest in those containing limiting nutrients.
