Soil Sampler, developed by Farmis, is a free Android application designed for farmers, agronomists, and farming corporations. It is the most popular tool for effective precision agriculture and getting soil samples in your fields. The app allows you to draw your field on the map or go around it using GPS measurement tools, set the sample grid size for each field, and start "accurate navigation" in your sample pick-up position.

Soil Sampler is the most advanced and effective way of taking soil samples in the shortest possible time. It is a real time-saver, navigating the user straight to the soil pick-up position, avoiding unnecessary movement around the field whilst doing so. Nowadays, farms use various precision agriculture machinery like GPS receivers, GPS navigators, parallel driving systems, tractor and harvester telematics and other tools like drones, UVA. While planning to do NDVI for plant grow index, plant seeding, and fertilization or variable rate maps for your farming equipment, a simple soil sample is mandatory.
