This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,936.

Background and Problem Solved

The original patent for disinfecting soil using electric voltage has limitations in terms of surface area of soil contact, killing effect on different types of microorganisms, and removal of microorganisms from the soil. The present invention addresses these limitations by introducing spiral-patterned electrodes, adjustable pulse frequency, and antimicrobial coatings, resulting in a more efficient and effective soil disinfection process.

Novelty and Inventive Step

The present invention provides a novel and non-obvious solution to the limitations of the original patent by introducing spiral-patterned electrodes, adjustable pulse frequency, and antimicrobial coatings, which significantly improve the efficiency and effectiveness of the soil disinfection process.

Alternative Embodiments and Variations

Alternative embodiments of the invention include using different electrode materials, varying the spiral pattern, and incorporating additional mechanisms for enhancing soil disinfection, such as UV light or heat treatment. Variations of the invention can be applied to different types of soil, including agricultural, industrial, and residential areas.

Potential Commercial Applications and Market

The enhanced soil disinfection system and method have significant commercial potential in the agricultural, environmental remediation, and construction industries, where soil contamination is a major concern. The invention can be used to improve crop yields, reduce environmental pollution, and create safer living environments.
