Cover Crops Enhance Aboveground Biomass, Soil Biological Activity and Soil Organic Carbon in Tropical Agroecosystems

Victória Santos Souza, Bruna Emanuele Schiebelbein, Carlos Roberto Pinheiro, Francisco Ruíz et autres

ABSTRACT In tropical agroecosystems, soil organic carbon (SOC) accrual is constrained by rapid organic matter turnover and seasonal water limitation. Cover crops are widely used to improve soil C inputs, but their effects on SOC fractions and soil biological activity can vary …

Soil physical potential of constructed Technosols from Iron mining tailings and construction and demolition waste

Beatriz Marchese Silva, Moacir Tuzzin de Moraes, Luiz Henrique Quecine Grande, Francisco Ruíz et autres

The unsustainable disposal of solid waste, such as mine tailings, construction and demolition waste, poses significant environmental challenges. In this context, the development of Technosols (engineered soils made from waste materials) emerges as a solution to support sustainable land management, by recovering …

Partitioning autochthonous and allochthonous carbon in mangroves of the Brazilian Amazon coast

Gabriel Coppo, Francisco Ruíz, Rodolfo Fagundes Costa, J. Boone Kauffman et autres

• Strong spatial differences in mangrove organic sources due to the Amazon River. • Autochthonous carbon predominates (>54%) in estuarine mangroves. • Allochthonous carbon makes up 34–38% of surface soil organic carbon. • Mangroves in deltaic settings have a 30% lower restoration …

Changes in soil organic matter content and quality in Amazonian mangrove forests converted to shrimp farms

Francisco Ruíz, T. L. D. Ferreira, Matheus Sampaio Carneiro Barreto, Cornelia RUMPEL et autres

Mangroves are highly efficient carbon sinks, yet they are increasingly threatened by aquaculture expansion. Moreover, the long-term impacts of shrimp farming on soil organic matter (SOM) quality and carbon sequestration in Amazonian mangroves remain poorly understood, particularly regarding changes in SOM composition …

Tracking mangrove restoration using a biogeochemical soil health index and ecosystem service indicators

Laís Coutinho Zayas Jimenez, Hermano Melo Queiroz, Maurício Roberto Cherubin, Francisco Ruíz et autres

Mangrove forests provide critical soil-related ecosystem services (ES), including carbon sequestration, contaminant retention, and nutrient cycling-all closely linked to soil health. However, land-use change and pollution increasingly threaten mangrove soils, compromising their functionality and ES provision. To reverse these impacts, effective strategies …

B-175 Comparative analysis of two methods for the determination of tacrolimus in whole blood

Tomás de Haro, María de los Ángeles Armijo Perterguer, Francisco Ruíz, José María Romero Noguera

Abstract Background Introduction Tacrolimus is an immunosuppressive drug from the calcineurin inhibitors group. It works by inhibiting the activation of T lymphocytes responsible for transplant rejection. Therefore, it is essential to establish an appropriate therapeutic regimen, maintain therapeutic levels, and detect toxic …
