MustGrow Biologics Corp. (TSX-V:MGRO, OTCQB:MGROF) said on Wednesday that its organic TerraSante biofertility product delivered substantial improvements in potato yields, size and quality in commercial farming trials in Washington State and Idaho, adding to evidence that the mustard-derived input could boost returns for growers.
A Washington State farmer using TerraSante at 11 pounds per acre on a large commercial field reported an estimated increase of about US$5,000 in value per acre, compared with a cost of roughly US$180 per acre for the biofertilizer, the company said.
Trials in Idaho also showed improvements in soil health and potato crop condition when used within existing production programs.
MustGrow said the results align with earlier small-plot US trials, which showed yield increases ranging from about 26% to nearly 40%, depending on the TerraSante application rate.
At 50 pounds per acre, TerraSante produced a 39.2% yield increase over untreated plots, according to company data.
TerraSante, derived from mustard plants, is a soluble organic biofertilizer designed to feed soil and soil microbes through plant proteins and carbohydrates. The product is registered for sale in California, Florida, Arizona, Idaho, Oregon and Washington, and carries Organic OMRI Listed certification and approval under California’s Organic Input Material program.
MustGrow said TerraSante is intended to support soil microbiome health, improve nutrient and water-use efficiency, and enhance crop performance without synthetic additives. The company highlighted the potential for healthier microbial communities to increase nutrient availability, reduce plant stress and improve yields.
The US harvested 927,000 acres of potatoes in 2024, generating US$4.6 billion in crop value, according to the Department of Agriculture.
