Outline

This study utilized Sentinel-2 satellite imagery to assess the impacts of widespread use of exogenous organic matter (EOM) in agriculture on soil and crop health. In particular, we focused on detecting the application of digestate, which contributes to soil fertility but also causes environmental hazards such as microplastic pollution and nitrogen loss. Spectroscopic characteristics of EOM were analyzed using EOMI, NDVI and EVI indices from Sentinel-2 satellite image time series analysis (SITS) for four crop types in Thessaly, Greece. Machine learning (ML) models such as Random Forest, k-NN, Gradient Boosting and Feedforward Neural Networks were used to detect the presence of digestate, achieving an F1-score up to 0.85. This study highlights the potential of combining remote sensing and ML to monitor EOM applications in a scalable and cost-effective manner to support precision agriculture and sustainability.

Takeaways, Limitations

Takeaways:
Presenting the efficiency and scalability of EOM (including liquid compost) application monitoring using Sentinel-2 satellite imagery and machine learning.
Presenting a new approach to precision agriculture and sustainable agricultural management.
Presenting the possibility of developing cost-effective environmental monitoring technology.
Limitations:
The study area was limited to Thessaly, Greece, so further research is needed to determine generalizability.
The performance of the machine learning model used may depend on the dataset.
Further research is needed on different types of EOM and soil conditions.
Lack of quantitative assessment of environmental impacts such as microplastic pollution and nitrogen loss.
