Seed Coating with Biochar
1.38 billion hectares in the world is consider arable land whereby seeds of annual crops are planted every year. This is historically associated with tillage of soil releasing soil carbon and detrimental to soil structure and biology. Biological seed treatments are seen as an opportunity to repair the detrimental effects of tillage, and facilitate the transition to reduced tillage systems while maintaining productivi-ty
Challenge is that biological seed treatments must be applied as soon as possible before planting the crop to ensure the micro-biology does not deteriorate. Biochar is the home for this soil micro-biology and this has the potential to reduce the loss of this applied microbiology as well as increasing the time in which the seed can be treated. This would greatly increase the practicality of applying seed treatments on farm.
