In a growing medium with very few nutrients or organic matter, the addition of biochar had no apparent effect on plant growth. However, in combination with added organic matter and inorganic fertiliser, the addition of biochar resulted in a noticeable increase in growth....
On the other hand, more fully carbonized biochars with lower VM content containing a smaller labile C component have a smaller effect on soil microbial activity and N immobilization. While our research provides one explanation for why some biochars have a negative effect on plant growth, it still...
Whilst its effect on C and nitrogen (N) cycling in soils has been investigated previously, this has usually either focussed on the bulk soil organic matter, or a single compound such as glucose. Five low molecular weight dissolved organic C (LMWDOC) substrates (three sugars, one amino acid...
Early blight incidence, percent disease index (PDI) and tomato plant response to disease was assessed thirty 4r days after transplanting on the basis of symptoms development and severity. The incorporation of biochar in plant growth medium has a suppressive effect onA. solanidevelopment on tomatoes ...
Wood gasification biochar had either no or slightly negative effect on plant growth. Abstract Gasification biochar (GB) contains recalcitrant carbon that can contribute to soil carbon sequestration and soil quality improvement. However, the impact of GB on plant-available water capacity (AWC) and plan...
However, a thorough functional assessment of biochar effect on plant growth and resource allocations is so far missing. Moreover, earthworms and biochar increase mineral nutrient availability through an increase in mineralization and nutrient retention respectively and are likely to interact through various...
We term this the “Shifted Rmax-Effect”. As there is no simple rule-of-thumb for crop/soil/biochar/dose/pathogen combinations, the possible effects of biochar on plant pathogens should not be overlooked. 展开 关键词: Biotic stress Hormesis effect Plant disease Plant productivity Soil amendment ...
A positive influence of biochar and AM fungi has been reported on soil and plant growth. Plant and soil nutrient status as well as water availability may benefit plant production when biochar is incorporated into soil, regardless of its effect on AM fungi in some cases. Biochar incorporation ...
(produced from greenhouse plant wastes) was found to mediate systemic resistance against Fusarium crown rot and to simultaneously improve tomato plant growth and physiological parameters by up to 63%. Transcriptomic analysis (RNA-seq) of tomato demonstrated that biochar had a priming effect on gene ...
Effect of indigenous AM fungi and BCAs on health of apple seedlings grown in replant disease soil The apple replant problem i.e. poor growth and short life of apple trees planted at sites where apple trees grew before, is wide spread and due to various abiotic and biotic stresses. These ...
