Dynamics of Soil Carbon Average Content Insights from a Global Approach to Clim...
Rodrigues, Cristina I. Dias; Brito, Luís Miguel; Nunes, Leonel J. R.This study provides an in-depth examination of the average values of gravi- metric carbon content, measured in grams per kilogram (g/kg), and the organic Carbon (OC) content, quantified in kilograms per square meter (kg/ m2), within various soil classifications and depths. Highlighting the relevance of such research, it delves into the intricacies of soil OC dynamics across diverse depth strata and offers a com...
Dynamics of Soil Carbon Average Content at Different Depths: Insights from a Gl...
Rodrigues, Cristina I. Dias; Brito, Luís Miguel; Nunes, Leonel J.R.This study provides an in-depth examination of the average values of gravimetric carbon content, measured in grams per kilogram (g/kg), and the organic Carbon (OC) content, quantified in kilograms per square meter (kg/m2), within various soil classifications and depths.

The composition and structure of bacterial and fungal communities in kiwifruit ...
Fernandes, Paulo; Cano-Díaz, Concha; Pinto, Rui; Mourão, Isabel; Brito, Luís Miguel; Moura, LuísaPhotoselective nets in agriculture are typically designed to modify the light spectrum, intensity, and microclimate around crops, influencing plant growth, productivity, and quality. However, knowledge regarding their impact on the microbiota of plants and fruits remains limited. This study assessed the impact of pearl, grey, and yellow photoselective nets on the microbial communities present on kiwifruit surfa...
Soil Vertical Distribution of Organic Carbon and Sequestration Potential in Pon...
Rodrigues, Cristina I. Dias; Brito, Luís Miguel; Nunes, Leonel J.R.Understanding the vertical distributions of organic carbon (OC) is crucial for predicting and simulating the influences of soil units on the terrestrial carbon cycle. The OC in the fine earth fraction was calculated for the soil units Anthrosols, Cambisols, Fluvisols, Leptosols, and Regosols in the municipality of Ponte de Lima, Portugal, at depths of 0–30 cm, 0–100 cm, 0–200 cm, and 0–2590 cm. In the study are...
Impact of Kiwifruit Waste Compost on Soil Bacteriome and Lettuce Growth
Fernandes, Paulo; Pinto, Rui; Correia, Cláudia; Mourão, Isabel; Moura, Luísa; Brito, Luís MiguelComposts produced with kiwifruit waste from the calibration process (KW), mixed with 5%, 10%, and 20% wheat straw (WS), were evaluated as crop fertilizers through a pot experiment with lettuce, arranged as a randomized block design. Highest lettuce yields were achieved with 20 and 40 t·ha−1 5%WS compost and 40 t·ha−1 10%WS compost, suggesting that the physical characteristics of the composts increased soil wate...
Valorization of kiwi waste through composting
Fernandes, Paulo; Pinto, Rui; Correia, Cláudia; Mourão, Isabel; Moura, Luísa; Brito, Luís MiguelKiwi waste from the calibration process is a major environmental problem of kiwi production due to landfill deposition. This work aims to contribute to the agronomic use of recycled kiwi waste through composting. With this objective, a composting experiment was carried out with kiwi fruit waste mixed with 5%, 10% and 20% (fresh weight) of wheat straw from bundles used to protect kiwifruit trunks from frost, as ...
Efeito do revolvimento no processo de compostagem de bagaço de uva com engaço
Brito, Luís Miguel; Pinto, Rui; Correia, Cláudia; Mourão, Isabel; Moura, LuísaA indústria vitivinícola gera uma grande quantidade de resíduos, e a compostagem é uma alternativa para a reciclagem destes resíduos com vantagens agronómicas e ambientais. Com este objetivo, o bagaço e o engaço de uva da casta Alvarinho, recolhidos antes da fermentação, foram compostados em pilhas estáticas e em pilhas revolvidas com três e seis revolvimentos, para investigar os efeitos das condições das pilha...
Composting waste from the white wine industry
Pinto, Rui; Correia, Cláudia; Mourão, Isabel; Moura, Luísa; Brito, Luís MiguelThe wine industry generates a large amount of waste, and composting is an alternative for recycling these residues with agronomic and environmental advantages. With this aim, grape marc and grape stalks were composted in static and turned piles, with three and six turns, to investigate the effects of pile conditions during composting in order to improve final compost quality. Thermophilic temperatures were atta...
Soil carbon sequestration in the context of climate change mitigation: a review
Rodrigues, Cristina I. Dias; Brito, Luís Miguel; Nunes, Leonel J.R.This review article aims to acknowledge the multifaceted functions of soil, and given its status as the largest terrestrial carbon store, to reaffirm its previously established importance in carbon sequestration. The article outlines the key variables that affect soil's ability to trap carbon and highlights the significance of soil in halting climate change. A bibliometric study of seven sets of keywords relati...
Effect of photo-selective nets on yield, fruit quality and Psa disease progress...
Moura, Luísa; Pinto, Rui; Rodrigues, Raúl; Brito, Luís Miguel; Rego, Rute; Valin, Maria Isabel; Mariz-Ponte, Nuno; Santos, Conceição; Mourão, IsabelThe influence of the colour of photo-selective nets on Actinidia deliciosa yield, fruit quality and progression of the bacterial kiwifruit canker (Pseudomonas syringae pv. actinidiae, Psa) need to be characterised due to increasing use of these nets, mainly to protect from hail and storms. From May 2019 onwards, pearl (Pn), yellow (Yn) and grey (Gn) nets were installed permanently in a ‘Hayward’ kiwifruit orcha...
