Assessing land use effects on ecohydrological partitioning in the critical zone through isotope-aided modelling
(Wiley, 2023-09-11)The study examines how different land uses impact ecohydrological processes in the critical zone, focusing on water partitioning between evaporation, transpiration, and groundwater recharge. Using stable water isotopes and ... -
Active and passive chlorophyll fluorescence measurements at canopy level on potato crops. Evidence of similitude of diurnal cycles of apparent fluorescence yields
(Springer Nature Link, 2022-12-17)We performed active and passive measurements of diurnal cycles of chlorophyll fluorescence on potato crops at canopy level in outdoors conditions for 26 days. Active measurements of the stationary fluorescence yield (Fs) ... -
Crecimiento de terneros utilizando cantidades limitadas de leche y formulaciones con niveles proteínicos diferentes
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1974-07)A total of thirty male Holstein calves that had received colostrum were fed with limited amounts of milk for a five-week period. From the third week on, part of the milk was replaced by a calf starter diluted in water, and ... -

A scenario modelling approach to assess management impacts on soil erosion in coffee systems in Central America
(Elsevier, 2023-05-05)Soil erosion is one of the major causes of soil degradation worldwide, because it causes the depletion of soil organic carbon, nutrients, and water holding capacity. In Central America, coffee production is vulnerable to ... -
A global meta-analysis of soil organic carbon in the Anthropocene
(Nature, 2023-06-05)The study is a global meta-analysis on soil organic carbon in the Anthropocene, based on more than 25,000 primary studies. It examines how land-use change, land management, and climate change affect soil organic carbon ... -
Estudio sobre el barrenador Hypsipyla grandella (Zeller) (Lepidóptera: Pyralidae). XXIII Efectos de radiación gamma en larvas, pupas y adutos.
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1974-01)In this study the effect of gamma radiation on last instar H. grandella larvae, pupae of early in advanced age, and adults was evaluated with reference to mortality, deformation, fecundity and longevity. Complete sterilization ... -
Pulpa y pergamino de café. V. Absorción y retención de nitrógeno en terneros alimentados con raciones elaboradas con pulpa de café
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1974-01)Nitrogen balance data of male, young Holstein calves, weighing 22 kg, fed diets containing 0, 12, and 24 per cent of day dehydrated coffee pulp, are presented. These diets were administered for a total of 18 days, with ... -
Influencia de la sombra sobre el crecimiento y la productividad de las hojas de Vigna sinensis L.
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1974-01)Leaf growth (surface, dry matter, number of epidemic cells) is studied through samplings effected twice a day. Various stages of leaf growth are thus determined, as well as leaf productivity during the day and the ...
