There are three main scenarios for using productivity zones: fertilizer application, sowing, and soil sampling. Let's take a look at how we go about defining productivity zones using the OneSoil web app as an example. Defining productivity zones.
No matter what fieldwork you need to conduct, open the Fertilizers or Sowing rate tabs in the OneSoil web app
. Select your field on the map. The app will process NDVI data for the last four years and display a productivity zone map. If you need to conduct a soil analysis,
use this map to take soil samples for each productivity zone. Our team is currently working on a separate tool for that. We'll let you know in our blog as soon as the tool is ready. If you're planning on applying fertilizer or seeding,
start by examining low productivity areas. We suggest reviewing these areas to determine the factors that limit their yield. Based on our experience, it's easier to start by analyzing the relief and soil brightness, the latter of which gives insights into organic nutrient content. Eliminate the limiting factor, if possible. After that, you can move onto the fieldwork.
