Soil electrical resistivity monitoring as a practical tool for evaluating irrigation systems efficiency at the orchard scale: a case study in a vineyard in Central Chile
Springer Science and Business Media LLC - Tập 39 - Trang 123-143 - 2020
J. Araya Vargas, P. M. Gil, F. J. Meza, G. Yáñez, G. Menanno, V. García-Gutiérrez, A. J. Luque, F. Poblete, R. Figueroa, J. Maringue, N. Pérez-Estay, J. Sanhueza
In many orchards, irrigation scheduling is designed based on data from meteorological networks and considering homogeneous soil properties. Such assumptions may result in inefficient irrigation, which is difficult to constrain without expensive or invasive techniques. Here we have evaluated the ability of the electrical resistivity tomography (ERT) for detecting meter-scale irrigation uniformity a...... hiện toàn bộ
Water scarcity and adoption of water-saving irrigation technologies in groundwater over-exploited areas in the North China Plain
Springer Science and Business Media LLC - Tập 39 - Trang 397-408 - 2021
Kunlin Yuan, Zhihai Yang, Shuhong Wang
Water-saving technologies (WSTs) have been publicized for many years in the North China Plain. However, WSTs are not well accepted and farmers have a preference for traditional irrigation technology rather than modern ones. This paper examines determinants of adopting traditional or modern WSTs, especially effects of water scarcity. Using cross-sectional data of 267 farm households, we first categ...... hiện toàn bộ
Plant indicators for scheduling irrigation of young olive trees
Springer Science and Business Media LLC - Tập 21 - Trang 83-90 - 2002
A. Moriana, E. Fereres
The sensitivity of several water status indicators was determined in irrigated young olive trees subjected to two drought periods at Cordoba, Spain. Trunk diameter fluctuations (TDF) were monitored continuously and stem water potential (ψ), leaf photosynthesis (P n) and conductance (g l) were measured periodically on trees where irrigation was inter...... hiện toàn bộ
Benthonic fauna of the Itata river and irrigation canals (Chile)
Springer Science and Business Media LLC - Tập 18 Số 2 - Trang 91-99 - 1998
Habit, E., Bertrán, Carlos, Arévalo, Sergio, Victoriano, Pedro
Benthonic fauna and substrate in three areas of the Itata river (rhithron riffles, rhitron pools, and potamon) and three irrigation canals at the outtake and about 500 m downstream are analyzed. Benthonic fauna included 56 taxa; of these, 12 were exclusive of the river, 11 were only found in irrigation canals, and 33 were in both environments. The widest distributions were found among the Diptera ...... hiện toàn bộ
Modelling and measuring evapotranspiration in a daily drip irrigated cotton field
Springer Science and Business Media LLC - Tập 12 Số 1 - Trang 13-20 - 1991
Mahrer, Y., Rytwo, G.
An eddy correlation system (ECS) was used to estimate evapotranspiration (E) in a daily drip irrigated cotton field. Cotton yield, water use, and their ratio (Water use efficiency; WUE) were compared in four irrigation treatments. Three treatments were irrigated at levels of 85, 100, and 115% of E, while the fourth was irrigated according to grower's usual practice. E data were used to verify a on...... hiện toàn bộ
Irrigation of seed carrots on a sandy loam soil
Springer Science and Business Media LLC - Tập 12 - Trang 193-198 - 1991
J. E. Ayars, R. B. Hutmacher, J. J. Steiner, A. B. Mantel, S. S. Vail
Little research has been reported which quantifies the response of a carrot (Daucus carrota L. var sativa DC.) seed crop to water management. While the area of seed production of this crop in the United States is less than 3000ha, the return ranges from US $2000 to $ 10 000 ha−1. Because of the need to mature and dry the seed on the plant, carrot seed is generally grown in areas with negligible su...... hiện toàn bộ
The effect of different fertigation strategies and furrow surface treatments on plant water and nitrogen use
Springer Science and Business Media LLC - Tập 34 - Trang 53-69 - 2015
Jirka Šimůnek, Keith L. Bristow, Sarah A. Helalia, Altaf A. Siyal
Furrow irrigation and fertigation systems should be designed and managed to optimize the availability of water and fertilizer to plants and minimize their losses through evaporation, deep drainage and leaching. We developed a furrow irrigation submodule for HYDRUS (2D/3D) and used it to evaluate the effects of different furrow soil surface treatments and different timings of fertigation on root wa...... hiện toàn bộ

Structured analysis of seepage losses in irrigation supply channels for cost-effective investments: case studies from the southern Murray-Darling Basin of Australia
Springer Science and Business Media LLC - Tập 31 - Trang 11-25 - 2011
Saud Akbar, Akhtar Abbas, Munir A. Hanjra, Shahbaz Khan
Much of inland Australia has been in perpetual drought since 1997 except during 2010 when above average rainfall occurred. It has been the worst drought since 1788 when European settlement began. Water scarcity poses a serious threat to the sustainability of the irrigated agriculture in major irrigation systems across the Murray-Darling Basin (MDB). There is a need for water-saving measures and a ...... hiện toàn bộ
