Operation condition	Results	Authors/date
Landfill leachate, leachate irrigation of woodland, full scale	Leachate concentrations of up to 1500 mg BOD5/l and 300 mg NH4 C-N/l, have been spray irrigated to woodland at appropriate loadings that show no detrimental effects on the irrigated vegetation;	Cornwall County Council [19].
Pilot-scale, land treatment system, treated wastewater from the stabilization pond system of the latex factory	The average removal efficiency of TKN, NH3-N, Org-N, BOD5 and sulfate for tropical carpet grass unit were 92, 97, 61, 88 and 52%, for water convolvulus unit were 75, 80, 43, 41 and 30%, and for control unit were 74, 80, 41, 31 and 28%, respectively.	Thongnuekhang V. and Puetpaiboon. U. [20].
Landfill leachate as irrigation water for tree and vegetable, full scale	The effects of landfill leachate on the growth of tree and vegetable crops were studied with 5, 10, 20 and 40% leachate dilutions than in the non-leachate control. Leachate-treated soil had elevated levels of electrical conductivity, total-, ammonia) and nitrate-N, exchangeable Na and P.	Wong M. H. and Leung C. K. [21].
Young synthetic acetogenic phase landfill leachate, at two hydraulic loading rates (HLR).	The results presented suggest that the HLR of leachate into soil arrays contributes to significant differences in the fate of the landfill leachate parameters (phenol, copper, and zinc) earlier	Kamenthren Govender [22].
Three-year field study, intensive leachate irrigation of two willow varieties	Two willow varieties were tested and four irrigation regimes in sixteen 400-m2 plots. The willow plants did not react negatively, despite very high annual loads of nitrogen, chloride and other elements.	Aronsson P. Dahlin T. Dimitriou I. [23].
Landfill leachate, leachate irrigation of grass and willows, full scale	leachate input (400 m3 per month per hectare in average) did not result in excessive accumulation of salts, heavy metals, or nutrients, which could negatively affect soil properties and plant growth	Justin M. Z. Zupanc M. [24].
Pilot plant scale, Landfill leachate, land treatment, slow rate irrigation, three rate 0.2, 0.6 and 1 ml/min	in order to remove COD, BOD5, TDS, TSS, TOC the best result was obtained in the region’s soil planted with Vetiver plant and at the speed of 0.2 ml per minute which resulted 99.1%, 99.7%, 52.4%, 98.8%, 94.9% removal efficiencies, respectively	This study
