Compositional and phytochemical characterization of four improved varieties of Puerto Rico sweet chili pepper (Capsicum chinense)
(2017)The pepper Capsicum chinense, is a key ingredient in Puerto Rican cuisine due to its flavor, aroma and in the case of local varieties, little to no pungency. Little is known about the nutritional value of this specialty ... -
Composta de estiércol bovino y su efecto en plantas de cobertura y propiedades químicas del suelo
(2017)Experiments were conducted to determine the effect of dairy manure compost (DMC) in nutrient concentrations in soil and cover crops (CC). In the first study, 60 Mg ha-1 of DCM on the CC: forage radish [Raphanus sativus ... -
Composting as an alternative method to dispose of slaughterhouse wastes in Puerto Rico
(2006)The elaboration, and chemical, physical and biological properties of compost made of organic wastes from a slaughterhouse (SHW) plant were evaluated. Freshly cut (FYT) and semi-decomposed (SCYT) yard trimmings were evaluated ... -
A comprehensive stormwater management plan: opportunities to incorporate stormwater wetlands into the University of Puerto Rico stormwater management program
(2022-08-29)The environment is continuously deteriorating due to the presence of human activity and the permanent landscape alterations that compromise the ecosystem. One of these practices is the discharge of large volumes of ... -
A comprehensive study of beachrock in Puerto Rico: morphology, texture, cementation and its implications in coastal processes, including coastal erosion.
(2023-06-01)Beachrocks in Puerto Rico are millennial-scale geologic features formed in coastlines by cementation of heterogeneous coastal sediments (sand and/or gravel). The factors and mechanisms of beachrock formation and its ... -
