A California-based startup named High-Degree is currently testing a steam-powered device intended to replace chemical soil fumigation. The prototype is undergoing field trials in Watsonville to target weeds and pathogens with extreme heat.
Combatting Verticillium wilt in Watsonville strawberry beds
The prototype developed by High-Degree was first rolled out in early October following several years of research and small-scale trials. According to the report, the machine operates on strawberry beds by scanning the ground with a series of probes. These probes activate steam vents in a specific pattern designed to cover the plant's root zone.
Early observations from these Watsonville field tests suggest a marked reduction in weed seed viability. Furthermore,the technology aims to decrease the prevalence of soilborne diseases, specifically Verticillium wilt, without relying on toxic chemicals. This approach seeks to address the historical issues of soil degradation and resistance development in weeds and nematodes caused by conventional chemical fumigants.
The energy-intensive challenge of high-temperature steam production
The energy required to produce high-temperature steam presents a significant operational challenge for High-Degree. Because the machine relies on vaporized heat,the energy consumption could be substantial,potentially impacting the cost-effectiveness for growers. As High-Degree continues its testing,the company must determine if the system can be scaled efficiently across larger operations.
The report mentions that the team is exploring the integration of solar power or heat-capture systems to help mitigate these high operating costs. Additionally, High-Degree is testing various soil types and crop rotations to ensure the technology's versatlity across the diverse agricultural landscapes of California's Central Valley.
Expanding trials to Central Valley corn and lettuce cultivars
High-Degree plans to expand its testing beyond strawberry beds by including lettuce and corn cultivars later this year. This expansion is a critical step in proving the machine's utility across different crop types and soil conditions. by diversifying the testing, the company hopes to compile a comprehensive performance report for the industry.
Successful trials with these new crops will allow High-Degree to share data with organic certification bodies. Proving that steam-based heat can provide comparable or superior control to chemicals is essential for the technology to be embraced by the organic farming community.
Seeking organic certification and agribusiness partnerships
High-Degree intends to partner with large agribusiness firms once the prototype proves both reliable and economical. This move could potentially reshape supply chains by offering a more sustainable alternative to traditional soil management methods.
Environmental advocates have already expressed interest in the initiative, noting that reducing chemical inputs is a major step toward reconciling food production with ecological stewardship. If the technology scales successfully, it could set a precedent for similar innovations across the United States.
