No, I have never encountered any information that would support beans being fertilized using animal parts or products. I’m wholly unaware of any such practice.

Some producers may use manure but it’s much more common for them to use chemically produced synthetic fertilizers containing Nitrogen, Zinc, and Potassium among others. Some bean fields will not require additional fertilizers at all.

I’ve attached a resource document on Idaho Soil Fertility and Bean Production.

Best Regards.
