Nutrient and Pest Mapping

field mapping

Point sampling grids for selected fields were constructed for site-specific data collection throughout the growing season. Factors important to a number of growers such as pH, soil nutrients, soil compaction, and presence/absence of various insects (potato leafhopper) and diseases (phytophthora) were measured. Spatial analysis technioques such as surface interpolation and statistical correlation were used to map and analyze such diverse factors as 1) the distribution and intensity of diseases, 2) insect outbreaks, and 3) the distribution of variables such as pH, soil type, soil nutrients, and organic matter. With spatial distributions known, farmers are able to move forward site-specific treatments, addressing with-in field variability. This saves time and money on pesticide and fertilizer applications and reduces nutrient run-off into watersheds.
