With high energy prices and Russian embargos pushing up fertilizer costs, New Hampshire farmers are returning to a homegrown nutrient source — sludge generated from wastewater treatment plants across the state.
The state’s only sludge hauler-processor has run out of its Class A product, a biosolid that contains fewer pathogens and is less regulated than the Class B product.
With some fertilizer prices doubling compared to last year, farmers have renewed their interest in Class B sludge. Holderness-based Resource Management Inc. (RMI) provides the Class B to farmers and spreads it on fields for free.
