Tracking the source of microplastics in soil : An exploratory case study in pea...
Veloso, Abel; Silva, Vera; Huerta Lwanga, Esperanza; Beriot, Nicolas; Monteiro, M.C.H.; Simões, M.P.; Geissen, VioletteIn the last 20 years, world plastic production has increased rapidly, reaching 4.00 × 1011 kg in 2022. However, less than 10% was recycled. Moreover, most conventional plastics are persistent and, therefore, remain in the environment long after their release. Although most studies on microplastic contamination focus on a single environmental compartment, an integrated and multicompartment approach is highly rec...
Dynamics of pesticide residues in soils during the growing season: a case study...
Veloso, Abel; Silva, Vera; Osman, Rima; Simões, M.P.; Monteiro, M.C.H.; Violette GeissenPermanent crops rely heavily on pesticides. Their short-term behaviour has already been characterised under laboratory conditions. However, their degradation in the field is still poorly understood. Furthermore, studies that relate pesticide residues in soil with their application history are still scarce, despite their relevance for inferring the historical and diffuse dimensions of pollution. This work explor...
Connecting present and future soil erosion risk in the upper Tagus river region...
Duarte, A.C.; Quinta-Nova, L. C.; Monteiro, M.C.H.Soil water erosion causes soil degradation, affecting its fertility and, consequently, leading to the loss of its productive capacity and may contribute to a process of desertification. Countries in the Mediterranean basin are under the influence of a climate pattern that is unfavorable to maintaining effective soil cover, with peak precipitation events occurring, and an increase in soil erosion rates is expect...
A systematic analysis of nutritional and mineral composition and toxicity in Ac...
Pedro, Soraia; Gonçalves, Joana; Monteiro, M.C.H.; Gonçalves, José Carlos; Gominho, Jorge; Gallardo, Eugenia; Anjos, OféliaIn the present study, the nutritive composition and mineral content of the leaves of eight species of Acacia trees were evaluated to assess their potential for different purposes, such as food resources for ruminants and mineral sources in soils. Caco-2 cells were employed to assess cytotoxicity, revealing that the extracts exhibited no cytotoxic effects after cellular incubation, suggesting their suitability a...
Biostimulants in organic vegetable nurseries: Study case in lettuce
Simões, Joana; Marmota, Carolina; Moreira, Lisa; Costa, Daniela V.T.A.; Correia, Helena E.; Pinto, António; Wessel, Dulcineia; Delgado, F.M.G.In order to create better conditions to achieve food safety and sovereignty, agroecology, as a science, looks for solutions for several steps of the technical itineraries of the crops. Crop nutrition and protection are two main crop itinerary components that have been in the center of farmers challenges and consumers concerns, and biopreparations, which have been prepared using natural substances, have been use...

Digestate not only affects nutrient availability but also soil quality indicators
García-López, Ana María; Delgado, António; Anjos, O.; Monteiro, M.C.H.Digestate contains many essential nutrients for crops, including nitrogen (N) and phosphorus (P), and it can alter the biogeochemical cycle of nutrients and soil functionality. This work aimed to assess the fertilizing effects of digestate on chemical and biological soil properties in a field experiment in eastern Portugal with two horticultural crops involving nine treatments: control without fertilization; mi...
Use of acacia pods as a source of vegetal organic matter for soil
Pedro, Soraia; Antunes, Carlos Alberto Lopes; Pitacas, F.I.; Monteiro, M.C.H.; Gominho, Jorge; Gallardo, Eugenia; Anjos, O.Incorporating vegetal organic matter into the soil releases nutrients and increases its contents in organic matter, which can provide higher soil productivity and lower susceptibility to compaction. Acacia is an invasive plant in Portugal, and the huge seed bank incorporated into the soil every year is problematic for their dissemination. Suppose the green pods can have a sustainable use contributing to soil fe...
Linking the present and future scenarios of soil erosion modeling in Tagus Inte...
Duarte, A.C.; Quinta-Nova, L.C.; Monteiro, M.C.H.A erosão hídrica do solo é considerada um dos processos que levam à degradação do solo, afetando a sua fertilidade e, consequentemente, a perda da capacidade de produção. O principal objetivo deste estudo foi avaliar a taxa de erosão no presente e a sua evolução futura na área do Parque Natural do Tejo Internacional. Os resultados obtidos fornecem insights sobre como os cenários futuros de desenvolvimento socio...
Linking the present and future scenarios of soil erosion modeling in Tejo Inter...
Duarte, A.C.; Quinta-Nova, L.C.; Monteiro, M.C.H.Soil erosion by water is considered one of the processes leading to land degradation, affecting soil fertility, and consequently the loss of production capacity. According to recent studies, the projected increase of soil loss rate in the next few decades in European Union agricultural areas is about 22.5%. In Portugal and other countries in the Mediterranean basin, under a climate pattern unfavorable to mainta...
