“…Soil moisture is a variable that integrates the water balance components of land surface hydrology (Rodriguez-Iturbe and Porporato, 2005), and over time it can be used to develop a record of antecedent hydrologic fluxes (Costa-Cabral et al, 2008). Indeed, the possibility of using changes in soil water content to estimate evaporation and other SWBCs has long been recognized (McGowan and Williams, 1980) (Koksal et al, 2017). Many studies, including Schelde et al (2011) and Guderle and Hildebrandt (2015), have shown that highly resolved soil moisture measurements contain a great deal of information that can be used to accurately determine ET and sink term, based on hydrologic balance, when the appropriate approach is used.…”

Abstract. An accurate assessment of soil water budget components (SWBCs) is necessary for improving irrigation strategies and optimizing the use of fertilizer in any water-limited environment such as the desert oases in arid northwestern China. However, quantitative information of SWBCs is usually challenging to obtain, because, since the water cycle is principally driven by irrigation (I), drainage (D), and evapotranspiration (ET) in desert oasis settings, none of the drivers can be easily measured under actual conditions. Soil moisture is a variable that integrates the water balance components of land surface hydrology, and the evolution of soil moisture is assumed to contain the memory of antecedent hydrologic fluxes, and thus can be used to determine SWBCs from a hydrologic balance. A database of soil moisture measurements from six experimental plots in the middle Heihe River Basin of China (NT1 to NT6, designed to investigate the long-term effects of cropping systems and agronomic manipulation on soil property evolution in the ecotone of desert and oasis) was used to test the potential of a soil moisture database in estimating the SWBCs. The experimental plots were treated as continuous pasture cropping, maize cropping, maize cropping with straw return, maize-maize-pasture rotation, maize-pasture rotation, and maize-pasture intercropping. We first compared the hydrophysical properties of the soils in the plots, including soil bulk density (ρb), vertical saturated hydraulic conductivity (Ks), and soil water retention features, and then determined evapotranspiration and other SWBCs through a data-driven method that combined both the soil water balance method and the inverse Richards function. Our results showed that although the tillage and planting of the past decade have significantly increased the soils' water-holding ability, the magnitude of increase in most of the parameters was independent of the treatments applied across the plots. Despite the relatively flat topography and consciously uniform irrigation, significant variances were observed among the plots in both the cumulative irrigation volumes (between 652.1 mm at NT3 and 1186.5 mm at NT1) and deep drainages (between 170.7 mm at NT3 and 651.8 mm at NT1) during the growing season of 2016. Obvious correlation existed between the volume of irrigation and that of drained water. However, the ET demands for all the plots behaved pretty much the same, with the cumulative ET values ranging between 489.1 and 561.9 mm for the different treatments in 2016, suggesting that the irrigation amounts had limited influence on the accumulated ET throughout the growing season. This work also confirmed that relatively reasonable estimations of the SWBCs in a desert oasis environment can be derived by using soil moisture measurements, and the results will provide a great potential for identifying appropriate irrigation amounts and frequencies, and thus move toward sustainable water resources management, even under traditional surface irrigation conditions.

“…Santos et al (2018) determined the total cumulative mean yield for the three harvests was 14.59 t ha -1 for the lysimeter-based system and 13.76 t ha -1 for cultivation using pinus bark. Koksal et al (2017) reported a maximum average yield of 42.4 t ha -1 for fully irrigated red peppers in the Northern part of Turkey. Albuquerque et al (2011), assessing the effects of different levels of irrigation and K doses in soil-grown bell pepper culture, found a mean yield of 18.58 t ha -1 over five harvests.…”

La investigación se realizó de abril a setiembre de 2016, en la Estación Experimental Agrícola Fabio Baudrit Moreno de la Universidad de Costa Rica, Alajuela, Costa Rica, con el híbrido costarricense de chile dulce ‘Dulcitico’, en sistema hidropónico bajo invernadero. Se evaluó el efecto de 2 densidades de siembra (1,4 y 2,4 plantas.m-2) y 3 volúmenes de sustrato (7, 14 y 21 L.planta-1) sobre el rendimiento, contenido de agua total disponible (ATD) en el sustrato, drenaje, evapotranspiración del cultivo (ETc) y eficiencia de uso de agua (EUA). Se utilizó un diseño de 3 bloques completos al azar con arreglo bifactorial de tratamientos 2 x 3. La ETc se obtuvo mediante balance de agua en el sustrato y la EUA como el cociente entre rendimiento y la ETc. Para todas las variables de respuesta, no se observaron diferencias entre ambas densidades de siembra, conforme se incrementó el volumen de sustrato desde 7 hasta 21 L (p<0,05). Ambos factores afectaron (p<0,05) de forma independiente a todas las variables; excepto el ATD y el rendimiento, que únicamente fueron afectados (p<0,05) por el volumen de sustrato y la densidad de plantas, respectivamente. En todos los casos, el efecto de mayor magnitud fue debido al factor densidad. El volumen de sustrato no afectó el rendimiento, sin embargo, contribuyó a mejorar la EUA al reducir los volúmenes de riego, de ETc y de drenaje. A mayor densidad de siembra incrementó el rendimiento (kg.m-2), pero redujo la EUA, debido a un mayor consumo de agua (ETc), y mayores volúmenes de riego, de ATD y de drenaje. La mayor EUA se obtuvo a 1,4 plantas.m-2 y 7 L de sustrato.planta-1, por una reducción de 13% en la ETc respecto al cultivo con 21 L de sustrato.planta-1 y 2,4 plantas.m-2.
