Influencia de los residuos vegetales en el nitrógeno de algunos suelos de cacao en Costa Rica
(IICA, Turrialba (Costa Rica), 1972)Los suelos bajo cultivo de cacao utilizados en el estudio, aluviales con influencia volcánica, fueron localizados en los predios del IICA-CTEI, Turrialba, Costa Rica. Esta área situada entre 580 y 990 msnm pertenece al ... -
Altitude and community traits explain rain forest stand dynamics over a 2370-m altitudinal gradient in Costa Rica
(2021-12)Stand dynamic rates in Earth’s vitally important tropical mountain rain forests are a central component of the response of these forests to global change, but their relationships to environmental gradients are poorly ... -
Functional recovery of secondary tropical forests
(Editorial Board, 2021-11)One-third of all Neotropical forests are secondary forests that regrow naturally after agricultural use through secondary succession. We need to understand better how and why succession varies across environmental gradients ... -
Multidimensional tropical forest recovery
(AAAS, Washington, DC (USA), 2021-12)Tropical forests disappear rapidly because of deforestation, yet they have the potential to regrow naturally on abandoned lands. We analyze how 12 forest attributes recover during secondary succession and how their ... -
Positive Effects of Scattered Trees on Soil Water Dynamics in a Pasture Landscape in the Tropics
(2021)As a result of canopy interception and transpiration, trees are often assumed to have negative effects on the local hydrological budget resulting in reduced soil and groundwater resources. However, it has also been shown ... -
Influence of different densities of cocoa and oil palm on yield performances of cocoa
(IICA, San José (Costa Rica), 1986)La presente investigación enfocó tres sistemas especiales de cultivo mixtos o intercalados de cacao y palma de aceite, bloques segregados de los dos cultivos (X), filas alternativas las de los dos (Y) y el arreglo del ... -

Claves para la identificación de algunas maderas en Costa Rica
(1987-10)Se presentan dos claves para identificar maderas de árboles que crecen en Costa Rica. La primera es una clave diagramática basada en características visibles con una lupa de 10X o bien a simple vista. La segunda es una ... -
Efeito da trifluralina na cinética de absorcao de fósforo pela soja
(1987-10)The effects of Trifluralin upon soybean (Glycine max (L.) Merrill, c.v. Paraná) phosphorus uptake and translocation were studied in nutrient solution, utilizing 32 p. Concentrations of 0 to 4 ppm of trifluralin (a.i.) were ...
