The viability of irrigating mandarin trees with saline reclaimed water in a semi-arid Mediterranean region: a preliminary assessment
Springer Science and Business Media LLC - Tập 31 Số 4 - Trang 759-768 - 2013
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
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...
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
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...
A proposal for reclamation by dilution of irrigation water
Springer Science and Business Media LLC - Tập 1 - Trang 161-168 - 1980
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...
Plant indicators for scheduling irrigation of young olive trees
Springer Science and Business Media LLC - Tập 21 - Trang 83-90 - 2002
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 interrupted or which were fully irrigated. During
the ...
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
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...
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
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...
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
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...
Benthonic fauna of the Itata river and irrigation canals (Chile)
Springer Science and Business Media LLC - Tập 18 Số 2 - Trang 91-99 - 1998
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 ...
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
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...
