Drip tubing was installed via subsurface injection. Suction lysimeters are incorporated throughout the LDP for shallow horizon monitoring of any nutrient leaching. ...
On of our biggest projects till now has been planning and installing a system of 24 giant lysimeters in a cocoa research farm. Due to climate changes cocoa plantations are struggling to adjust to the new conditions in the tropical areas. This lysimeter system was designed according to our clients needs, determined to find the best irrigation plan for cocoa ...
Lysimeter Carousel is a development of advanced, cost-effective irrigation technologies.The purpose of the system is to measure growth data while providing uniform growth conditions.The system is controlled and managed by an advanced "Crystal OPC" human-machine interface (HMI), which enables the collection, recording, analysis and presentation of the data obtained in a ...
This involves three Eijkelkamp Smart Lysimeter measuring stations, which in addition to evapotranspiration data also provide data about the amount of precipitation, wind and soil moisture. ...
Actual daily evapotranspiration (ETa) was measured in two weighing micro-lysimeters, from 1 July 2009 to 30 June 2011 on an alpine meadow in the Qilian Mountains, northwest China. ...
In addition to research locations in the USA, he has had research projects in Egypt, the Middle East and Uzbekistan on crop water use, irrigation scheduling and soil water measurement; and he has worked in China, Egypt, Jordan and the USA to build and use weighing lysimeters to measure crop water use. Since 2003, Dr. Evett has been the ARS research coordinator for the Middle East ...
Lysimeter studies can be used to identify and quantify soil degradates of agrochemicals (“metabolites”) which have the potential to leach to groundwater. However, the apparent metabolic profile of such lysimeter leachate samples will often be significantly more complex than would be expected in true groundwater samples. ...
Gas exchange techniques, sap flow measurements, and the crop evapotranspiration minus micro-lysimeter method were used to evaluate plant transpiration. Transpiration data were subsequently compared with the dynamical normalized leaf area-based extrapolation. ...
HYDRUS-1D was combined with lysimeter experiments to study extinction depth and steady water storage in root zone (Ws) of groundwater evaporation (ETgw) under winter wheat and silt soil. ...
The results may benefit the pomegranate juice and byproduct valourisation industries, especially in the face of global water quality deterioration.Keywords: anthocyanins, antioxidative capacity, cyanidin, delphinidin, ellagic acid, health value, lysimeters, pelargonidin, phenolics, pomegranate, Punica granatum L., punicalagin, salinity, preharvest, ...
Seasonal changes in the performance of a catch crop were investigated using lysimeters in a full-scale greenhouse experiment with 50 d cultivation of dent corn. ...
This study was conducted to determine the evapotranspiration of cucumber, tomato and peppers, using micro–lysimeter during seven months in a greenhouse located in central region of Iran. Reference evapotranspiration estimated using drainage lysimeters and the water balance of soil micro–lysimeters was determined using the gravimetric method. ...
Evaluation of the changes in physico-chemical properties of soils and crops grown with pulp and paper mill wastewater in field lysimeters were carried out for three years at the Integrated Pulp and Paper Mill, Madhya Pradesh (India). ...
Introduction of compost as filter materials could enhance COD removal efficiencies but also contribute colour in treated leachate.Keywords: composting, cover soil, leachate treatment, lysimeter, rainwater infiltration, tropical landfill, compost mixture, mixed soil, rainfall intensity, filter materials, COD ...
Where hillslopes are connected to receiving surface waters by continuous concrete frost, snowmelt runoff at the watershed scale may be enhanced.Keywords: boreal plain, concrete frost, frozen soil infiltration, snowmelt lysimeter, snowmelt ...
This research was conducted using field cover soil lysimeters placed at the surface of a solid waste dumping area and batch experiments in the laboratory. ...
Clipping yield, clipping tissue total Kjeldahl nitrogen (TKN), and N uptake were measured or calculated in four 4-wk growth periods per year. Suction lysimeters were used to collect soil water below the rootzone (leachate) to determine nitrate and ammonium concentrations once every two weeks. ...
Leachate was collected from the base of the blocks in 35-mL increments using a 64-cell grid lysimeter. Even before any rain was applied, approximately 300 mL of water from the liquid manure (30% of that applied) was transported through the no-till soil, but none through the tilled blocks. ...
The application of the model has raised issue like effect on water balance by the variation of short-term rainfall into percolation.Keywords: evapotranspiration, HELP model, hydrological evaluation, landfill performance, landfill leachate, lysimeter, water balance, water management, Nepal, rainfall, percolation, precipitation, leachate ...
Objectives were to install, calibrate, and assess soil water characteristics of paired weighing lysimeters at Saint Joseph, LA. Installed in 2005, the lysimeters have inner tanks 1.5 m long, 1.5 m deep, and 1.0 m wide that rest on load cells within outer tanks. ...
