The Soil Quality App (SQAPP) is the flagship deliverable of the EU-Horizon 2020 iSQAPER project. The SQAPP was designed with the idea that it should provide the user with the opportunity to access fragmented data on soil quality and soil threats in an easy-to-use way. Moreover, the user should not only receive indicator values, but be guided in interpreting these values by providing more contextual information: is a certain indicator value high or low in a given context? The system is set up to use soil quality and soil threat indicators for which spatial data exist as a first estimation for soil quality parameters in a given location, but these values can be replaced with more accurate own data by the app user. Ultimately, the user receives, based on an assessment of the most critical issues, management recommendations on how soil quality can be improved and soil threats be overcome.

Following the release of the beta version of SQAPP, some 90 European stakeholders (researchers, farmers, students, advisory services and policy makers from Slovenia, Poland, Portugal, Greece, Spain, France, Estonia, Romania and Netherlands) evaluated, for their own locations, the information provided by SQAPP about soil quality properties, soil threats and recommendations for agricultural management practices. In this report we review the results of the evaluation. The stakeholders' responses were used to refine the subsequent versions of SQAPP.

A preliminary study on the agreement of measured soil properties from 37 georeferenced locations in Europe and China and the values estimated by SQAPP for the same locations.

We discuss the accuracy of soil properties and soil threats classification based on soil properties estimates of the Soil Quality App (SQAPP) and the correlation and agreement with the soil properties and soil threats classification using measured physical, chemical and biological soil properties, for the same location. The final goal is to assess if SQAPP can be used to monitor soil quality improvement, and the adequacy of the recommendation system.

Because the SQAPP algorithm is spatially explicit, we assess whether it could be used to support the development of need-based and targeted agricultural policies.

In 2018, as part of their MSc programme, students of Wageningen University and Research undertook a field evaluation of the performance of SQAPP (beta version) in terms of its accuracy, relevance and functionality. Their feedback was used in the continued development of SQAPP.
