Satellite-based estimation of soil organic carbon in Portuguese grasslands
Morais, Tiago G.; Jongen, M.; Tufik, C.; Rodrigues, N.R.; Gama, I.; Serrano, João; Gonçalves, M.C.; Mano, R.; Domingos, T.; Teixeira, R.F.M.Introduction: Soil organic carbon (SOC) sequestration is one of the main ecosystem services provided by well-managed grasslands. In the Mediterranean region, sown biodiverse pastures (SBP) rich in legumes are a nature-based, innovative, and economically competitive livestock production system. As a co-benefit of increased yield, they also contribute to carbon sequestration through SOC accumulation. However, SOC...

Characterization of portuguese sown rainfed grasslands using remote sensing and...
Morais, Tiago G.; Jongen, Marjan; Tufik, Camila; Rodrigues, Nuno R.; Gama, Ivo; Fangueiro, David; Serrano, João; Vieira, Susana; Domingos, TiagoGrasslands are crucial ecosystems that support and provide a diverse number of ecosystem services. Sown biodiverse pastures rich in legumes (SBP) were developed with the main goal of increasing grassland production while minimizing fertilizers inputs. In this paper, the main properties of SBP in Portugal were estimated using remote sensing and machine learning in six different farms and two production years (sp...

Morais, Tiago G.; Tufik, Camila; Rato, Ana E.; Rodrigues, Nuno R.; Gama, Ivo; Jongen, Marjan; Serrano, João; Fangueiro, David; Domingos, TiagoGrasslands in Portugal are key managed ecosystems, supporting and providing a diverse number of ecosystem services. Here, we developed a procedure for rapid estimation of soil organic carbon (SOC) in soil samples of sown biodiverse permanent pastures rich in legumes (SBP) in Portugal. We combined laboratory NIR spectral data analysis with artificial neural networks (ANN) to estimate the SOC content of SBP soil ...
