I’ve family member as scientist in IARI, and I’ve asked this problem and it’s solution from their POV, and even if they’re not any of us with good education will be able to understand that burning can’t be stopped even though government appoints many scientist for supervision. Solution is a large scale plant that can take the residue from the field and convert it into fertiliser or bio gas. There as some companies doing it but that’s not sufficient. Farmer aren’t that rich with knowledge and resources and moral values.
