This is an interesting topic. I am not certain it is doable. What I would be concern with is that whatever is done has to be both financially viable and operationally feasible. Too often these are overlooks as we tend to make labor intensive innovations with the underlying assumption readily available and diets are enough to undertake the additional labor. Unfortunately, this is rarely the case for smallholder farmers. My prime example is that I would expect that composting crop residues would require more caloric energy then would be derived from the extra yield obtained. Calorie deficit is a major problem in most smallholder communities leading to major labor shortages. Please review the following webpages:
