The Adapt-N platform utilizes data from several high-quality weather data providers. Our models automatically incorporate daily inputs for temperature, precipitation, and solar radiation at a 4 km (approximately 2.5 mile) resolution or greater. These data are captured from a combination of radar estimated and ground observational sources, with trusted methods for extending observations to areas where no physical weather stations exist. The Adapt-N research team regularly evaluates the accuracy of different weather providers and identifies the most appropriate source(s) for each service region. Some customer implementations also have the option to utilize on-farm weather stations when they exist within 0.5 km of a field.
New climate data is acquired several times per day, and the associated rainfall amounts shown on the recommendation page are updated without delay (although in some cases they are error-adjusted as additional stations report ground readings, so they may change slightly in the first 24-48 hours after the event). However, since Adapt-N is simulating what's actually happening in a field in real-time, it can take up to 3-4 days for the effects of that precipitation to fully impact a recommendation in a meaningful way. In the case of leaching, for example, it can take 1-2 days for the water to move through the soil profile; for denitrification, it takes a few days for the soil to go into an anaerobic state. Adapt-N models these impacts and adjusts the recommendations accordingly, and of course these rates will differ depending on soil type, rooting depth, slope, and other factors.
A good rule of thumb is to review the recommendation 3 full days after a rainfall event ends.
