Contract awarded for Purchase 24 sets of soil moisture sensor per layer of lysimeter
depth was 700 mm but collection pipes were inserted at 300 mm.
The sowing was performed on 01 December 2015, whose soil material was initially placed in field capacity, placing five seeds per lysimeter
at a depth of 2 cm, and equidistantly distributed.
Samples were also collected from each lysimeter
location and at each depth, and were pooled.
Likewise, different micrometeorological methods have been used for the estimation of ET, such as Bowen Ratio (BR), Eddy Covariance (EC), Optical Scintillation (OS), and weighing lysimeter

It measures the crop evapotranspiration rate (ETc) directly." Fletcher notes that previously the only way to measure the ETc directly had been by using a lysimeter
, which was expensive and cumbersome.
The weighing lysimeter
is fabricated by a box with impermeable walls that is filled with soil and placed in a field with either a bare surface or Vegetation cover.
compacted select foundry byproduct liner (a mixture of casting sand and dust), each overlain with 2-feet of foundry sand byproduct waste material and underlain with a lysimeter
, a device that collects liquids released at the base of the test pad.
Huo et al  studied the effect of the groundwater level and irrigation amounts on the water use of wheat in a lysimeter
experiment at the Hongmen experimental station located in the Henan Province, China.
Here, [C.sub.n] is the N concentration (TN, N[H.sub.4] +, and [N[O.sub.3].sup.-]]) from leaching water collected from lysimeter
in the different rice growing stage, kg N [m.sup.-3]; [Q.sub.w] is the quantity of leaching water in the corresponding stage collected from lysimeter
, [m.sup.3]-[ha.sup.-1]; and [Q.sub.n] is the quantity of N leaching loss, kg [ha.sup.-1].
Seeds of three sunflower genotypes (SF -187, S-287 and HYSUN-33) were sown in lysimeter
and three salinity levels (control, 9 and 12 dS m-1) were developed by using NaCl salt.
