Applying fertilizer based on satellite imagery

A well made prescription map (also called an application map or VRA – variable rate application) can save you a lot of money when fertilizing your field while ensuring your crops receive the nutrients they need. Current satellite imagery serves as a particularly useful basis for such maps, especially in the case of nitrogen fertilization. To create a satellite image based prescription map, follow these 6 steps: 1. Choose an image The map will be based on the satellite image you choose in the SatAgro “Explorer” (A). We recommend using data acquired by Sentinel2 satellites or commercial data available in the Premium…

Soil sampling – planning

What are the benefits of using SatAgro to plan soil sampling? The state of your crop is at the same time a result and an indicator of the underlying soil’s chemistry. With SatAgro’s help you can easily plan soil sampling based on biomass variability. The results will be more accurate and can be transformed into a prescription map within SatAgro. For example, in a particularly wet year parts of the field experience inundation that stops the crop from developing. These wet zones are visible on satellite imagery. The field can thus be divided into two areas, where: The current crop…

Soil sampling – uploading lab results

Once you have received the test results, find the field zoning generated earlier in the “Diary” section. In the table above the zoning preview, there are now only zeroes. To fill out the table with results, click on the “Edit” button. You can now enter the values for the properties tested in each individual zone. If you have received the results in the form of electronic files (preferably spatial, e.g. .shp) you can send us the results by clicking “Import”. Remember that we must be able to unambiguously assign the results to specific parts of the field – it is…

Soil sampling – applying fertilizer based on results

To create a variable variable rate map based on the results of a soil survey, just follow these few steps – if you have already made a fertilisation map based on a satellite image, most of the process will be familiar to you. 1. Display the sampling results in the “Explorer” Select “Soil sampling” from the “Show on map” list. The map will show the division of the field into zones, and on the left side of the map you will see a selection of characteristics/components. Select the soil property based on which you want to plan a precision treatment,…

Precision treatment files

When you decide to download precision treatment files for use in the field or in different software, the system will ask you to choose a file format: shp – also called a Shapefile, ESRI shapefile, .shp. You can edit this file yourself in GIS software – for experienced users. ISOXML – file format used in ISOBUS compatible machinery. anl – file format compatible with AGROCOM MAP software csv – basic file format for tabular data, accessible in e.g. Excel kml – this can be used in Google Earth terminal’s format – CHOOSE THIS OPTION if you plan to use the…
