PAQ has developed a fertilizer product sales database to support the IPNI NuGIS project. This database compiles 23 years worth of fertilizer sales data from the American Association of Plant Food Control Officials (AAPFCO) and each record details the product sale by County, Year, Season, Product, Container, intended use, percent N, P, & K, and volume sold. The raw data consists of over 8 Million records and is stored on a dedicated database server.
PAQ also developed customized scripts and algorithms to perform estimates using the AAPFCO data that allow us to estimate volume of Farm fertilizer nutrients at the county level for all years, in all states.
