Having a lot of fragmented information about satellite crop monitoring systems (SCM) we decided to make more detailed review and compare different solutions where it is possible.
We took the most popular services available worldwide and compared them based on functionality.

One disadvantage of all systems is their high dependency on cloud coverage; therefore, we do not assign the maximum rating of 10 points to any of the systems. It is necessary to mention several of the systems are using a number of satellites – including microwave capable satellites. Such satellites “combined” decrease limitations resulting from cloud coverage and this significantly improves the frequency and quality of received data.
|Relief and Drainage Maps||+||–||–||+|
All services include a very efficient zoning tool based on different zoning criteria.
On field measures
** potato and beet
We assigned Cropio the highest score (not maximum) due to: a. the variety of on field measures; b. quality and depth of data; like: weather forecasting for individual field, soil moisture at the different depths, dew point, N-deficit of amount of required fertilizer, etc. Cropio has more on field capabilities and they are measured in real life units (kg, m3, cm).

Agronomist tools greatly differ when comparing to other systems making it somewhat difficult compare. Theoretically, each system has enough or almost enough data to use the agronomist tools we list in our review but only one system incorporates user friendly instruments for reviewing tasks.

*** available in additional product
We separate Management tools from Agronomist tools since not all of these are necessary for the small famers with only 20 or 50 hectares. Although these very valuable features for mid and large sized companies that from now, for example, can have a better understanding of the harvest value at any point in time.
|Field Zoning for Optimized Soil Tests||+||****||–||+|
|Integrated Private Weather Stations||+||–||–||–|
**** available at additional cost
Additional tools are tools that are not directly related to crop monitoring but could be very applicable in other areas, like lowering the cost of soil testing and integration of other systems.
