The C/[C.sub.0] data for the leaching experiment under irrigation were plotted for each individual lysimeter
on a linear scale.
Six suction lysimeters
were installed at increasing distances downslope of the baits, at 2 m, 10 and 18 m (see Figure 2).
There are other micrometeorological methods available for ET estimation (i.e., BR, weighing lysimeter
, and EC).
First, concrete lysimeters
were constructed and used to measure ET for alfalfa.
Yang et al  quantified water fluxes in large weighing lysimeters
, with a fluctuating groundwater table between 1.6 and 2.4 m during the wheat growth period and 0.7 and 2.3 m during the maize growth period, and found that, in a rotation system of wheat and maize, the cumulative capillary upward flux and the deep percolation were 89.6 and 55.9 mm, respectively.
During 2010 and 2011 seasons, soil water samples used for the leaching calculations were collected from lysimeters
Plant material, growth and treatment condition: A lysimeter
(1x1 m area) study was conducted at Saline Agriculture Research Centre, University of Agriculture, Faisalabad.
comparison of the role of waste characteristics in the formation of mineral deposits in leachate drainage systems, Waste Manage Research 24: 560-572.
The study can be used for optimization of the cropping pattern and can further be improved by estimation of crop water requirement using Lysimeter
studies to be carried out in the study area.
Incharge DRIP Muhammad Khan Mari also briefed the Federal Secretary about the functioning of laboratory and lysimeter
of the Institute.
Each column was connected at 3 cm above the base to a Mariotte siphon, which maintained the water-table at a constant depth of 100 cm below the soil surface and also metered the solution that moved into the lysimeter
to replace that evaporated from the surface or transpired by the crop.
