Abstract: (1152 Views) |
Biochar can reduce the plants vulnerability to diseases with different mechanisms such as improving soil fertility, increasing the population and activity of beneficial microorganisms, limiting the activity of pathogens, absorbing toxins produced by pathogens, stimulating the production of antibiotics, inducing plant systemic defense and changes in root exudates. The role of biochar in reducing plant diseases depends on the biochar properties, biochar dosages, soil properties, crop, and the type of pathogen. The biochar properties are affected by the type of biomass and production temperature. In addition, the mechanisms of biochar to protect the plant against each type of pathogens may be different. Therefore, considering the importance of biomass type and carbonization temperature in the efficiency of biochar, it is suggested to pay more attention to the ability of biochars produced from different biomasses and temperatures to reduce plant diseases. |
