On behalf of Vultus AB (publ), Lyckeby, together with Hushallningssallskapet, has conducted field trials aimed at developing an algorithm for the analysis of satellite images that provides potato growers with a clear picture of their fertilization needs throughout the growing season. The collection of data over three years of field trials has resulted in a unique service for precision fertilization, specifically developed for potato growers. Comparative studies using petiole analysis as a reference value, performed by students from SLU's Master's program, show that Vultus analyses achieve greater accuracy compared to industry-accepted methods.
