Combined amendment of BPC and PS significantly improved
both the physical and chemical conditions of the salt-stressed soil
and thus increasing wheat production through a decline in soil
salinity. This could be accounted for by the multiple benefits on
salt leaching, improvement of soil fertility, nutrient supply and
translocation to the grain under the amendment. This experiment
suggested a great potential to use a combined amendment of poultry
manure compost with biochar and the pyroligneous solution
from crop straw pyrolysis for alleviating salt stress in croplands.
However, the mechanism behind deserves further research.
