Partial replacement of mineral fertilisers with animal manures in an apple orch...
Esteves, Catarina; Costa, Eva; Mata, Miguel; Mota, Mariana; Ribeiro, Henrique; Fangueiro, DavidPartial replacement of mineral fertilisers (MF) with animal manures is a good alternative to reduce MF use and increase both nutrient cycling in agriculture and soil organic matter. However, the adoption of this practice must not lead to increased environmental impacts. In this two-year study conducted in an apple orchard, MF were partially replaced with various animal manures, including cattle slurry (CS), aci...
Partial replacement of chemical fertilizers with animal manures in an apple orc...
Esteves, Catarina; Fangueiro, David; Mota, Mariana; Martins, Miguel; Braga, Ricardo P.The combined use of chemical fertilisers with organic materials in crop fertilization is an essential approach to transition towards a more sustainable and resilient agriculture in Europe. In an apple orchard, chemical fertilisers (CF) were partially (25 to 57%) replaced with animal manure (cattle slurry - CS, acidified cattle slurry - ACS, cattle solid manure - CsM, and poultry manure - PM), based on the crop’...
Late Preterm Newborns: Do We Already Know Everything About Them?
Pereira, Miguel Paiva; Esteves, Catarina; Fernandes, Cláudia; Ferreira, Ana Rute; Lucas, Mafalda; Rodrigues, Ana; Matos, Cristina; Serrão Neto, AnaIntroduction: The preterm birth rate is on the rise, and late preterm deliveries account for 75% of preterm deliveries. Late preterm newborns were for many years considered full-term newborns; however, their particularities have been recognized in the last decade, particularly in terms of the higher rate of complications in the neonatal period. This study aimed to analyze the factors associated with greater mor...
Projecto Nutri2cycle: soluções para a circularidade de nutrientes e carbono na ...
Alvarenga, Paula; Prado, Joana; Esteves, Catarina; Silva, Arejacy; Fangueiro, DavidO projeto Nutri2Cycle (Horizonte 2020), tem como principal objetivo desenvolver os mecanismos que permitam uma circularidade mais eficiente de carbono e nutrientes (principalmente N e P), entre o setor agrícola e a produção animal, levando ao desenvolvimento de uma agricultura mais sustentável nos diferentes sistemas agrícolas Europeus. Neste sentido, é vital o contributo tecnológico do processamento, que permi...
Assessing the contribution of ECa and NDVI in the delineation of management zon...
Esteves, Catarina; Fangueiro, David; Braga, Ricardo; Martins, Miguel; Botelho, ManuelPrecision fertilization implies the need to identify the variability of soil fertility, which is costly and time-consuming. Remotely measured data can be a solution. Using this strategy, a study was conducted, in a vineyard, to delineate different management zones using two indicators: apparent soil electrical conductivity (ECa) and normalized difference vegetation index (NDVI). To understand the contribution o...
Remote Sensing (NDVI) and Apparent Soil Electrical Conductivity (ECap) to Delin...
Esteves, Catarina; Ribeiro, Henrique; Braga, Ricardo; Fangueiro, DavidThe intensification of agriculture has greatly enhanced crop productivity, but also its potential environmental impact. Nutrient recycling and an increase in resource use efficiency are the key points to keep production at high levels with minimum impact. The present work’s goal was to provide new insight on the spatial variability of soil chemical properties in a vineyard. For this, three different zones were ...
Development of the HIV360 international core set of outcome measures for adults...
Marques‐Gomes, João; Salt, Matthew J.; Pereira‐Neto, Rita; Barteldes, Franca S.; Gouveia‐Barros, Vera; Carvalho, AlexandreObjectives: HIV outcomes centre primarily around clinical markers with limited focus on patient-reported outcomes. With a global trend towards capturing the outcomes that matter most to patients, there is agreement that standardizing the definition of value in HIV care is key to their incorporation. This study aims to address the lack of routine, standardized data in HIV care. Methods: An international working ...
