Light respiration by subtropical seaweeds

open access: yesJournal of Phycology, 2017
Here, we report the first‐ever measurements of light CO2 respiration rate (CRR) by seaweeds. We measured the influence of temperature (15–25°C) and light (irradiance from 60 to 670 μmol · m−2 · s−1) on the light CCR of two subtropical seaweed species, and measured the CRR of seven different seaweed species under the same light (150 μmol · m−2 · s−1 ...

Tropopause pressure change in January during 1979-1992

open access: yesMeteorologische Zeitschrift, 2000
The global tropopause pressure change for the Januaries 1979 - 1992 is shown. In the extratropics over the North Atlantic-European region there is a marked large scale wave pattern with a pressure decrease of 2 hPa/yr over central Europe.

Green manuring for tropical organic cropping – A comparative analysis [PDF]

open access: yes, 2008
Green manuring is an essential component of tropical organic farming. Field studies evaluated the use of three legumes as in situ or ex situ green manures, along with a nonlegume green manure and a control to ascertain their impacts on soil properties ...

Biochar‐based fertilizers increase crop yields in acidic tropical soils

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Depletion of soil organic carbon and nutrients creates mounting challenges for agricultural production in tropical regions, putting livelihoods and food security at risk. Biochar‐based fertilizer (BBF) has been suggested as a tool to maintain yields while concurrently improving soil organic carbon content and related soil functions. This study

Production of a nutrient enriched biochar: a techno‐economic feasibility analysis

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract A techno‐economic feasibility analysis was conducted for a biomass pyrolysis plant that utilized Eucalyptus to produce fertilizer‐enriched biochar. Key parameters – biomass throughput, fertilizer loading, and selling price – were optimized for financial viability using net present value (NPV), internal rate of return (IRR), return on ...
