Our Story

After selling a specific agricultural product that wasn’t working, Ray Stock reported his customers’ feedback to senior management. They advised Ray to, “Find new customers,” in order to solve the problem. Ray’s customers responded by offering to support Ray (who had 4 children and a wife to provide for) if he were to decide to develop a product for them. With that, Ray set off to develop a new product that solved his customer’s needs, and Bactifeed was born.

With 20 years of experience collaborating with agronomists in the fertilizer industry, Ray Stock set out to develop a safe soil amendment founded on 4 basic principles.

The 4 Es:

1. Easy to use

2. Easy to apply

3. Efficient 

4. Effective
