Biochar Increases Water Use Efficiency in Eucalypt Plants Under Water and Nutri...

Soil amendment with biochar is being considered as a strategy for improving available soil water and nutrient content and, thereby, plant performance. Our aim was to investigate whether physiological, biochemical and morphological responses of Eucalyptus globulus to biochar amendment were dependent on watering regime. We conducted a randomized, 6-week greenhouse experiment with 5-month old eucalypt rooted cutti...

Influência da utilização de uma cobertura orgânica no restabelecimento a médio-...

Ao longo das últimas décadas Portugal tem sido um dos países com maior incidência de fogos florestais na Europa. Um número crescente de estudos tem vindo a ser desenvolvido no sentido de encontrar estratégias de recuperação e gestão de áreas ardidas. A aplicação de coberturas orgânicas sobre a superfície do solo pós-incêndio é atualmente utilizada eficazmente como forma de proteger o solo da erosão. Porém, pouc...

Biochars in soils: towards the required level of scientific understanding

Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level of scientific understanding (LOSU) regarding the consequences of biochar application to soil were explored. Five broad thematic areas of biochar research were addressed: soil biodiversity and ecotoxicology, soil organic matter and gre...

Short-term exposure to carbaryl and UV radiation increases the reproduction out...

Purpose: Ecotoxicological risk assessment of chemical compounds is considered more accurate when mixtures of chemicals and/or interactions between chemicals and natural stressors are considered. To further simulate natural conditions, under which organisms are often exposed to combinations of natural and anthropogenic stressors, the combined exposure of a widely used insecticide, carbaryl, under UV radiation wa...

Reductions in soil surface albedo as a function of biochar application rate: im...

Biochar can be defined as pyrolysed (charred) biomass produced for application to soils with the aim of mitigating global climate change while improving soil functions. Sustainable biochar application to soils has been estimated to reduce global greenhouse gas emissions by 71–130 Pg CO2-Ce over 100 years, indicating an important potential to mitigate climate change. However, these estimates ignored changes in s...

Sustainability, certification, and regulation of biochar

Biochar has a relatively long half-life in soil and can fundamentally alter soil properties, processes, and ecosystem services. The prospect of global-scale biochar application to soils highlights the importance of a sophisticated and rigorous certification procedure. The objective of this work was to discuss the concept of integrating biochar properties with environmental and socioeconomic factors, in a sustai...
