Variety specific relationships between effects of rhizobacteria on root exudation,growth and nutrient uptake of soybean

Aims

It has been increasingly recognized that only distal lower order roots turn over actively within the <2 mm fine root system of trees. This study aimed to estimate fine root production and turnover rate based on lower order fine roots and their relations to soil variables in mangroves.

Methods

We conducted sequential coring in five natural mangrove forests at Dongzhai Bay, China. Annual fine root production and turnover rate were calculated based on the seasonal variations of the biomass and necromass of lower order roots or the whole fine root system.

Results

Annual fine root production and turnover rate ranged between 571 and 2838 g m^?2 and 1.46–5.96 yr^?1, respectively, estimated with lower order roots, and they were increased by 0–30 % and reduced by 13–48 %, respectively, estimated with the whole fine root system. Annual fine root production was 1–3.5 times higher than aboveground litter production and was positively related to soil carbon, nitrogen and phosphorus concentrations. Fine root turnover rate was negatively related to soil salinity.

Conclusions

Mangrove fine root turnover plays a more important role than aboveground litter production in soil C accumulation. Sites with higher soil nutrients and lower salinity favor fine root production and turnover, and thus favor soil C accumulation.

Soil CO2 efflux in a bioenergy plantation with fast-growing Populus trees – influence of former land use, inter-row spacing and genotype

Aims

In this study we quantified the annual soil CO₂ efflux (annual SCE) of a short rotation coppice plantation in its establishment phase. We aimed to examine the effect of former (agricultural) land use type, inter-row spacing and genotype.

Methods

Annual SCE was quantified during the second growth year of the establishment rotation in a large scale poplar plantation in Flanders. Automated chambers were distributed over the two former land use types, the two different inter-row spacings and under two poplar genotypes. Additional measurements of C, N, P, K, Mg, Ca and Na concentrations of the soil, pH, bulk density, fine root biomass, microbial biomass C, soil mineralization rate, distance to trees and tree diameters were performed at the end of the second growth year.

Results

Total carbon loss from soil CO₂ efflux was valued at 589 g m^?2 yr^?1. Annual SCE was higher in former pasture as compared to cropland, higher in the narrow than in the wider inter-row spacings, but no effect of genotype was found.

Conclusions

Spatial differences in site characteristics are of great importance for understanding the effect of ecosystem management and land use change on soil respiration processes and need to be taken into account in modeling efforts of the carbon balance.

Announcing the call for the Special Issue on the 20th International Congress of the International Union of Pure and Applied Biophysics (IUPAB)—virtual meeting,October 2021

This Commentary describes a call for submissions for the upcoming Special Issue focused on the science presented at the 20^th IUPAB Congress to be held in conjunction with the 45^th Annual Meeting of the Brazilian Biophysical Society and the 49^th Annual Meeting of the Brazilian Society for Biochemistry and Molecular Biology.

Due to the COVID-19 pandemic, the 20^th International IUPAB Congress will take place as a virtual meeting this year from October 4 to 8, 2021. This triennial IUPAB Congress will be held in loose conjunction with the 45^th Annual Meeting of the Brazilian Biophysical Society and the 49^th Annual Meeting of the Brazilian Society for Biochemistry and Molecular Biology. To act as a complement to this virtual meeting, the Biophysical Reviews journal will base a Special Issue on the scientific topics of the meeting contributors selected from the range of invited speakers and poster presenters. This Special Issue will also work to highlight the host country’s (Brazil) National Biophysical Society. Finally, this Special Issue will also serve to publish the meeting abstracts in supplemental form.Review articles from IUPAB Congress speakers and poster presenters to the IUPAB Congress and associated conferences (the 45^th Annual Meeting of the Brazilian Biophysical Society and the 49^th Annual Meeting of the Brazilian Society for Biochemistry and Molecular Biology) are solicited. Similar to the SI based on the 19^th IUPAB Congress held in Edinburgh summarizing Commentaries from session chairs are also requested (Hall and dos Remedios 2017). The Special Issue for the 20^th IUPAB International Congress will be prepared and edited by the current authors (Rosangela Itri, Mauricio Baptista, Richard Garratt, and Antonio Jose Costa-Filho).
