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 ...
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. ...
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. ...
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, ...
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. ...
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 ...
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. ...
Pesticides applied to bermudagrass (Cynodon dactylon L.) can be captured by the canopy, absorbed by the roots, or bound in the thatch layer, which reduces the amount available to leach compared with a fallow soil system where pesticides may be applied directly to soil. 14C-Simazine was applied to dormant bermudagrass and fallow soil in lysimeters in a cold growth chamber (5°C) ...
Soil samples from 0 cm to 105 to 180 cm depth were obtained in fall and spring for NH4–N and NO3–N analyses. Ceramic cup tension lysimeters were installed at depths of 75 to 120 cm to monitor NO3–N in soil pore water. ...
Evapotranspiration was measured using weighing lysimeters (205 mm in diameter by 625 mm in length) inserted in turfgrass field plots (10 m2). ...
An experiment covering a 2-yr spring wheat (Triticum aestivum L.) catch crop succession was conducted in lysimeters to account for the losses of N due to leaching. We sought to relate these losses to the N uptake of the main crop and to integrate the estimated N loss and uptake into a balance. ...
The experiment at either site had five N rates on wheat (0–360 kg N ha–1 in 90-kg increments) and NO3–N in leachate were collected by wedge-shaped fiberglass wick lysimeters. At either site, the N-wheat yield quadratic response curve was fitted quite well and a significantly linear relationship between N rates and seasonal NO3–N masses in leachate was also found. ...
Fertilizer N was applied as 15N-labeled ammonium sulfate to corn (in a corn/soybean rotation) sown under zero tillage in filled-in lysimeters containing two soils of different texture representative of the Pampean region (52 and 78 kg N ha-1, added to the silt loam and sandy loam soil, respectively). Total fertilizer recovery at corn harvest averaged 84 and 64% for the silt loam ...
In addition, zero tension drainage lysimeters were buried 0.6 m below the beds in several treatments to monitor leaching of water and nitrate nitrogen. ...
The plot was treated with chlorothalonil, chlorpyrifos and profenofos according to normal agricultural practices of the Cameron Highlands. Water (runoff and lysimeter), soil and bedload sediment samples were taken according to a sampling schedule. ...
