Satellite-based estimation of soil organic carbon in Portuguese grasslands

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 monitoring in...

Characterization of portuguese sown rainfed grasslands using remote sensing and...

Grasslands 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...

Alternativas económicas na suplementação de ovinos de leite em pastagem : resul...

O presente trabalho foi desenvolvido no âmbito do Projecto Sheep 4.0, com o objetivo de potenciar a sustentabilidade dos sistemas de produção de ovinos de leite, integrando uma avaliação de efeitos alimentares, económicos, sociais e ambientais que permitirá imprimir um selo de sustentabilidade à produção extensiva.

Grasslands 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 ...

Retropupilar positioning of foldable iris-claw intraocular lens for correction ...

Summary: Iris-claw intraocular lens (ICIOL) for aphakia needs a large 5.4 mm corneal incision for its implantation. The technique needs corneal suture, associated with some postoperative astigmatism. Foldable ICIOL is used in phakic patients undergoing refractive surgery and has the advantage of a sutureless small corneal incision. We report a case of a high myopic patient with dislocated intraocular lens (IOL)...
