TL;DR: In this paper, the authors synthesized 20 years of research to explain the interrelated processes that determine soil and plant responses to biochar and found that biochar can catalyze biotic and abiotic reactions, particularly in the rhizosphere, that increase nutrient supply and uptake by plants.

TL;DR: The results of this investigation provide evidence for a complex series of reactions during composting, where dissolved nutrients are first taken up into biochar pores along a concentration gradient and through capillary action, followed by surface sorption and retention processes which blockBiochar pores and result in deposition of a nutrient-rich organomineral (plaque) layer.

TL;DR: The successful demonstration of biochar materials highlights the potential for further development of P filters for wastewater treatment systems from anaerobic digestate produced and pyrolysed on-site with energy recovery.

TL;DR: Thermal conversion of plants from less severely contaminated soils, demolition wood and food waste anaerobic digestate (AD) into biochar proved to be promising for land application, and in particular, food waste AD biochar contained very high nutrient concentrations, making it interesting for use as fertiliser.

TL;DR: It showed that the percentage of available PTEs was highest for biochars produced at the highest treatment temperature (HTT) of 750°C and available K contributed most to the osmotic pressure and high pH which negatively affected the seedlings.
