Research shows soil test analyses are significantly more accurate when agricultural production fields are soil sampled after they have been harvested, but before any field tillage has taken place. This app streamlines communication between soil samplers and producers concerning when the field has been harvested, when the field has been sampled, and when the soil analysis has been received from the lab. This app makes the process highly efficient by enabling users to notify soil samplers which fields have been harvested, by a single touch of the screen. Likewise, there is a one-touch process for the soil sampler to notify the producer that his field has been sampled, so that field tillage can proceed.
