Can fried peanut beans be buried directly in the flower bed?

I don't know what the landlord wants to do. If it is fertilization, it is suggested that peanut beans be crushed and buried on one side of the flowerpot, which is conducive to the slow absorption of flowers, reducing the damage to the root system of flowers, and also conducive to fertilization in a different direction in the future. But generally speaking, if peanut beans are only fried, they will not burn their roots.
