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
Optimization of canopy resistance models for estimating evapotranspiration on summer maize in a semi-arid condition of China
Springer Science and Business Media LLC - - Trang 1-16 - 2023
Cun Zhan, Lu Zhao, Yaling Zhang, Xinbei Lin, Gang Zhou, Zetao Zheng
Accurate estimation of evapotranspiration (ET) is crucial for improving crop water-use efficiency and facilitating precision irrigation. The Penman–Monteith (P-M) model is a widely used approach for ET calculation, with canopy resistance (rc) acting as a critical determinant of accuracy that is greatly affected by meteorological, crop, and soil factors. This study focused on the calibration of two...... hiện toàn bộ
A proposal for reclamation by dilution of irrigation water
Springer Science and Business Media LLC - Tập 1 - Trang 161-168 - 1980
W. A. Jury, G. Sinai, L. H. Stolzy
A proposal is developed for reclamation of a soil which has become salinized from irrigation with saline water. The procedure permits continued irrigation after dilution of the saline irrigation water with higher quality water, which achieves partial reclamation without taking the land out of production, and without creating a large flux of drainage. Model calculations using a salt transport-chemi...... 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
The influence of optimized allocation of agricultural water and soil resources on irrigation and drainage in the Jingdian Irrigation District, China
Springer Science and Business Media LLC - Tập 38 - Trang 37-47 - 2019
Jingsi Li, Liangjun Fei, Shan Li, Zhongxing Shi, Lihua Liu
Reasonable regulation of irrigation and drainage is an important way to decrease water resource waste and water pollution, and to ensure the sustainable utilization of water resources. In this study, appropriate irrigation and drainage methods are proposed by optimizing agricultural water and soil resources based on the current status of water resource utilization in irrigation district in Northwe...... hiện toàn bộ
Effect of irrigation regimes on persistence of Salmonella enterica serovar Newport in small experimental pots designed for plant cultivation
Springer Science and Business Media LLC - Tập 26 - Trang 1-8 - 2007
Nirit Bernstein, Shlomo Sela, Sarit Neder-Lavon
Increased outbreaks of foodborne illness throughout the world have raised concern over the potential health hazard of pre-harvest colonization of crops by human pathogens originating from contaminated irrigation water, or manure-amended soil. Contradictory reports currently exist concerning the ability of pathogenic bacteria to penetrate internal plant tissues via the root and translocate to edibl...... hiện toàn bộ
Effects of improved field practice on crop yield, water use and profitability of irrigation in Central Chile
Springer Science and Business Media LLC - Tập 1 - Trang 97-105
L. A. Gurovich
The economic impact of improved irrigation practice was studied for a number of years in a research project carried out in Central Chile on commercial fields of eleven orchard, field, vegetable and forage crops. The cost of implementing improved irrigation practice specific to a given soil-climate and crop combination, and the benefits obtained through that technology were evaluated with respect t...... 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
