About me.
Hi, I’m Marcel Harabin — founder of Green Revive Organics.
Green Revive Organics was created with a clear purpose: to introduce advanced, soil-focused fertilizer technology to the United States and make it accessible to growers and agricultural operations looking for more than just conventional nutrients.
As a Slovak American, I’ve always maintained close ties to Slovakia. Through those connections, I was introduced to Rokosan, a company specializing in innovative organic-based fertilizer technology developed through the hydrolysis of natural protein materials, including poultry feathers. After building a direct relationship with their team and gaining a deeper understanding of their process, I recognized the potential this technology could bring to the U.S. market.
What sets this approach apart is that it doesn’t just feed plants — it supports soil health. By converting feather byproducts into a biologically active, plant-available nutrient source, this technology helps improve microbial activity, organic matter balance, and long-term soil performance. The goal is not only stronger growth and better yields, but healthier soil over time.
There is also a broader sustainability opportunity. Poultry farms generate significant feather byproduct that is often treated as waste. This same material can be processed into valuable agricultural inputs, creating a circular and environmentally responsible solution that benefits both farming operations and soil systems.
At Green Revive Organics, my role is to connect this proven European technology with customers and partners here in the United States. My focus is on building long-term relationships, providing straightforward information, and supplying products that deliver real results without inflated marketing claims.
This is more than simply selling fertilizer. It’s about introducing smarter, more sustainable solutions that support plant performance, soil health, and the future of agriculture.
