Soil Organic Carbon Assessment Using Remote-Sensing Data and Machine Learning: ...
Lima, Arthur A. J.; Lopes, Júlio Castro; Lopes, Rui Pedro; Figueiredo, Tomás d'Aquino; Vidal-Vásquez, Eva; Hernandez Hernandez, ZulimarIn the current global change scenario, valuable tools for improving soils and increasing both agricultural productivity and food security, together with effective actions to mitigate the impacts of ongoing climate change trends, are priority issues. Soil Organic Carbon (SOC) acts on these two topics, as C is a core element of soil organic matter, an essential driver of soil fertility, and becomes problematic wh...
Improving soil health through nature-based solutions: the effects of olive-poma...
Royer, Ana Caroline; Lado, Marcos; Fonseca, Felícia; Hernandez Hernandez, Zulimar; Figueiredo, Tomás d'AquinoLoss of soil organic matter (SOM) is a major issue in Mediterranean regions, especially in NE Portugal, where about 70% of soils are classified as Leptosols. On the other hand, olive groves dominate the region's farmland, and the olive oil industry generates large quantities of by-products. Two-phase olive pomace (OP) has a high organic load and is phytotoxic due to its high phenolic content. Composting OP with...
Performance of ESA-CCI-SM Satellite product for estimating soil water deficit: ...
Figueiredo, Tomás d'Aquino; Royer, Ana Caroline; Hernandez Hernandez, ZulimarThe Mediterranean climate is characterised by hot and dry summers and water deficit in soils. Monitoring soil water deficit is of crucial importance in Mediterranean cropland, allowing a more cost-effective soil and water management. Satellite-borne data sources provide high temporal resolution information but usually lack the spatial resolution to adequately account for soil variability, namely on the physical...
Impacts of soil humic acids on the presence of PPCPs in reclaimed water
Conde-González, J.E.; Hernandez Hernandez, Zulimar; Aguiar, V.; Vera, L.; Marrero, M.C.; Salvadó, V.; Peña-Méndez, E.M.A multidisciplinary approach investigates the interaction between selected PPCPs with diversified physicochemical propertiesand humic acids (HAs) extracted from Elliot and volcanic soils in reclaimed water (RW). Principal component analysis (PCA) reveals significant differences between the two HAs and how these differences affect PPCP-HA interaction which are characterized by UV spectroscopy. The sorption of PP...
Avaliação de boas práticas agrícolas para a conservação de solo e água na horta...
Gusmão, Andressa Griebler; Feniman, Eduardo; Figueiredo, Tomás de; Hernandez Hernandez, Zulimar; Gusmão, Andressa GrieblerO projeto PRR HARVEST – Valorizar a horta familiar de modo a educar para uma dieta mediterrânica, saudável e sustentável – tem por objetivo promover o consumo de alimentos provenientes da agricultura familiar para a salvaguarda da Dieta Mediterrânica que, além dum padrão alimentar saudável, contempla valores culturais baseados na sustentabilidade ambiental. Como atividade transversal foi elaborado um inquérito ...
Nutrients concentration and uptake by ryegrass after soil amendment with olive-...
Royer, Ana Caroline; Lado, Marcos; Fonseca, Felícia; Hernandez Hernandez, Zulimar; Figueiredo, Tomás deOlive groves are predominant in the agriculture of Northeast Portugal. Two-phase olive pomace was composted with sheep manure and almond shell to obtain olive pomace-based composts (OPC). This plant efficacy trial evaluates the effects of composts, application dose and irrigation regime on foliar concentration and nutrient efficiency use by ryegrass. Three OPCs containing different proportions (%) of olive poma...
Biochars Derived from Olive Mill Byproducts: Typology, Characterization, and Ec...
Lustosa Filho, José Ferreira; Silva, Ana Paula Ferreira da; Costa, Silvana Teixeira; Gomes, Helder; Figueiredo, Tomás de; Hernandez Hernandez, ZulimarIn the context of climate change and the circular economy, biochar agricultural and envi- ronmental applications have attracted a good deal of attention. Biochar has unique characteristics like surface area, porosity, water-holding capacity, pH, surface charge, and nutrients. This study reviews the biochar production from olive pomace (OP) and olive stone (OS) byproducts, its chemical and physical characterizat...
Effect of different substrates on the growth rate and water efficiency of Querc...
Gusmão, Andressa Griebler; Toloto, Matheus de Oliveira; Segatelli, Ana; Fonseca, Felícia; Cortez, José Paulo; Figueiredo, Tomás deThe cork oak (Quercus suber) is significant for its economic and environmental impact. In 2013, Picões (Trás-os-Montes, Portugal) experienced a major forest fire (14,912 ha), destroying over 256,64 ha of cork oak forests. Due to degraded soil and steep slopes in the area, forest regeneration wasn’t fully achieved. As part of Ecology Day, funded by EEA Grant, this study aims to reforest 32 ha on the slopes of th...
Estimativa da eficácia de barreiras em curva de nível na redução da erosão hídr...
Okada, Vinicius; Hernandez Hernandez, Zulimar; Henriques, Renato; Figueiredo, Tomás deO Nordeste de Portugal enfrenta um desafio significativo de degradação do solo devido à erosão hídrica, um fenómeno intensificado pelas condições climáticas e de uso do solo da região. Esse problema é especialmente evidente na área dos Lagos do Sabor, onde as encostas estão particularmente vulneráveis a erosão (mediana do declive é de 25 graus), intensificada devido ao incêndio de Picões de 2014, que afetou cer...
Evaluation of compost application on soil organic carbon sequestration and phys...
Toloto, Matheus de Oliveira; Lima, Arthur A.J.; Segatelli, Ana; Royer, Ana Caroline; Gusmão, Andressa Griebler; Hernandez Hernandez, ZulimarGlobal carbon (C) cycle and atmosphere pollution remediation depended directly on C terrestrial sequestration and storage. In this context, soil organic carbon (SOC) plays an extremely important role by creating and enlarging C pools, such as organic amendments input over croplands. The present research aims to evaluate the outcomes from three types of compost (A, B and C) to a Leptosol, in an olive grove (NE P...
