Many farmers burn crop residue to control chemical resistant weeds. This is a resource going up in smoke and farmers have the opportunity to capture this residue to produce bioenergy and biofuels. To achieve this outcome, it is important to understand how the by-products of the bioenergy process, like biochar will affect our cropping systems.
Farmers on soil types low in potassium import Muriate of Potash (MOP) to use in wheat crops. Since wheat straw has Potassium, we wanted to ask the question, is there potential to mine Potassium from soil types typically high in potassium, process the straw through pyrolysis to produce bioenergy and biochar and use the biochar to replace potassium in a cropping regime?
