Rhizol Improves Soil Health and Crop Nutrition

Independent field research confirms Rhizol strengthens nutrient retention and uptake

Independent research has confirmed that microbial soil inoculants can play a major role in improving soil health and crop nutrition. A large field-based study using more than 1,000 soil samples showed that soils treated with Rhizol had stronger nutrient retention and better organic matter levels than untreated soils. 

"Growers want products that prove themselves in the field, not just in a lab. What this independent data shows is exactly what growers who integrate Rhizol in their operations are experiencing.  Rhizol helps keep nutrients where they belong, strengthens soil function, and supports better in-season crop performance. It's a practical tool that delivers real value across different soil types and management systems," said Zach Lancaster, Director of Field Agronomy & Grower Relations at ProGro BIO. 

The study was conducted using real field conditions before planting and after harvest. Researchers analyzed how key nutrients such as phosphorus, potassium, sulfur, and micronutrients behave in treated and untreated soils. The results showed that nutrient movement was lower in Rhizol-treated soils, meaning more nutrients remained available in the root zone for crops. 

Keeping nutrients in the soil is important because it reduces losses caused by leaching, runoff, and volatilization. When nutrients stay in the root zone, crops can use them more efficiently, and fertilizer investments become more effective. This also supports cleaner water and better environmental protection. 

The research also showed that treated soils experienced a significant increase in humic matter. Higher humic matter levels indicate improved soil structure, stronger biological activity, better moisture retention, and increased soil nitrogen. These improvements make soil more productive and resilient over time. 

Plant tissue tests were also completed at multiple locations. Crops grown in treated soils showed higher levels of essential nutrients in plant tissue. This indicates improved nutrient uptake, which supports stronger early growth, improved stress tolerance, and better yield potential. 

With fertilizer prices remaining uncertain and environmental expectations increasing, tools that help protect nutrients and improve soil performance are becoming more valuable. The research shows that improving soil function can deliver both agronomic and environmental benefits. 

"Farmers are being asked to do more with less—protect their soils, reduce nutrient loss, and still deliver strong yields. Rhizol's remarkable ability to provide a dual benefit – stronger agronomics and improved environmental stewardship – is increasingly important as growers balance productivity with compliance and sustainability objectives. These exciting, independent findings validate what growers have demonstrated time and again: when the soil performs better, the entire system performs better," said Blake Young, CEO of ProGro BIO. 

These findings confirm that strengthening soil health is one of the most effective ways to support consistent crop productivity while reducing nutrient loss and improving long-term sustainability.
