In Canada, the agricultural significance of potatoes is particularly prominent in provinces like New Brunswick. According to the 2022 Canadian Potato Acreage Report, produced by the United Potato Growers of Canada, there have been significant changes in how and where potatoes are grown in Canada recently.

In the eastern provinces, the report found there’s been a reduction in seeded acreage. It attributes this phenomenon primarily to higher fuel and fertilizer costs; as a result, potato growers have been looking for nutrient-management practices that optimize crop quality and yields.

In the field of technology, advances in optical sensors and their wavelength ranges have led to wide-ranging applications of spectroscopy to evaluate the nutritional composition of plants using machine learning techniques. Spectroscopy instruments have been widely researched to assess nutrients in plants based on leaf chemical content such as in fingered citron. Another use is to assess nutrients in degraded vegetation using near infrared spectra.
