Saturated hydraulic conductivity and steady infiltration rate are essential parameters in irrigation, and drainage projects, as well as in hydrological and climatological modelling. These data are hardly found in widely used soil databases in Brazil, and they are still reported in dispersed publications. This study aims to rescue SIR and Ks data for the state of Rio de Janeiro and make them available to users. In total 934 measurements of Ks and 24 of SIR were compiled. The soil types most frequent measured were Gleissolos and Neossolos, as well agriculture and pastures for the land-use system. The most popular methods to evaluate the Ks were constant head in the lab and the Guelph permeameter in field evaluations, and for the SIR, the double ring method. The data ranged from 0.40 to 1073 mm h-1. The lack of information in some regions of the Rio de Janeiro States indicates priority areas for increasing Ks and SIR determination. |

The in-situ quantification of turbulent flux and evapotranspiration (ET) is necessary to monitor crop performance in stressful environments. Although cacti can withstand stressful conditions, plant responses and plant?environment interactions remain unclear. Hence, the objective of our study was to investigate the interannual and seasonal behaviour of components of the surface energy balance, environmental conditions, morphophysiological parameters, biomass yield and water relations in a crop of Nopalea cochenillifera in the semi-arid region of Brazil. The data were collected from a micrometeorological tower between 2015 and 2017. The results demonstrate that net radiation was significantly higher during the wet season. Latent heat flux was not significant between the wet season and dry season. During the dry-wet transition season in particular, sensible heat flux was higher than during the other seasons. We observed a large decline in soil heat flux during the wet season. There was no difference in ET during the wet or dry seasons; however, there was a 40% reduction during the dry-wet transition. The wet seasons and wet-dry transition showed the lowest Evaporative Stress Index. The plants showed high cladode water content and biomass during the evaluation period. In conclusion, these findings indicate high rates of growth, high biomass and a high cladode water content and explain the response of the cactus regarding energy partitioning and ET. |
