“…Greater values of 1070-1300, 983-2117 and1189 mg/L were previously recorded by other studies (Ghafari et al, 2010;Palaniandy et al, 2010;Aziz et al, 2009). The high content of ammonia nitrogen is the main factor that enhances algal growth, promotes eutrophication, disrupts biological treatment operations, and reduces dissolved oxygen .…”

“…Landfill leachate mainly consists of large amounts of organic matter including dissolved organic matter, phenol, ammonical-nitrogen, phosphate, heavy metals, sulphide, hardness, acidity, alkalinity, salinity, solids, inorganic salts, and other toxicant (Foul et al, 2009;Aziz et al, 2009;Renou et al, 2008;Kang et al, 2002;Wang et al, 2002). The complexity of these characteristics makes the leachate more difficult to manage.…”

The general characteristics of Kuala Sepetang Landfill Site (KSLS) and Kulim Landfill Site (KLS) in the northern part of Malaysia were investigated. The average values of the parameters for leachate at KSLS and KLS, such as pH (8.05 and 7.59), EC (11.9 and 2.92 mS/cm), ORP (-33.02 and +17.8 On the other hand, parameters such as pH, copper, iron, manganese, nickel, and zinc remained within the allowable limits. The measured leachate would need an appropriate treatment strategy to reduce the pollutants to a satisfactory level prior to discharge into receiving system.

“…The high suspended solid level in the leachate may be attributed to the presence of organic and inorganic compounds. 17 After leachate treatment with 4 g/L FeCl 3 at pH 7, the contents of Cd, Al, Fe, Pb, Cu and Zn decreased by 100%, 64.4%, 51.9%, 82%, 56.8% and 96.6%, respectively. The optimal removal capacity for suspended solids (SS) was 80%.…”

“…Landfill leachate mainly consists of large amounts of organic matter, including dissolved organic matter, phenols, ammoniacal nitrogen, phosphates, heavy metals, sulfides, solids, inorganic salts, and other toxicants, and is characterised by hardness, acidity, alkalinity, and salinity. 16,17 The complex pollution and toxicity impacts of leachates have imposed the need to standardise pre-treatments prior to discharge for quality improvement. 18 Treated leachates contain nutrients and minerals that can possibly be transformed for fertigation.…”

HOW TO CITE:Alaribe FO, Agamuthu P. Fertigation of Brassica rapa L. using treated landfill leachate as a nutrient recycling option. S Afr J Sci. 2016;112(3/4), Art. #2015-0051, 8 pages. http://dx.doi.org/10.17159/ sajs.2016/20150051 Optimising nutrient availability and minimising plant metal contamination are vital in sustainable agriculture. This paper reports experiments in which treated leachate was used at different concentrations with predetermined N content for fertigation of Brassica rapa L. (leafy vegetable). An inorganic fertiliser, with N content equivalent to the leachate amount, was also prepared, as well as a control. Growth (leaf length, leaf width and stem height), harvest parameters (total number of leaves, root length and root dry weight) and specific growth rates (mm/day) were determined for three consecutive seasons. The dry weights of leaves, roots and stems in the leachate treatments were within the ranges of 1.95-3.60 g, 1.18-3.60 g and 0.33-1.37 g, with biomasses of 1.75 g, 1.14 g and 0.2 g, respectively, which were higher than those of the control. B. rapa L. fertigated with 25% diluted treated leachate recorded high specific growth rate and a leaf length of 0.53 mm/day and 0.23.17±0.58 cm, respectively (%N=0.023; p<0.05). The maximum permissible mineral concentration set by the Food and Agricultural Organization of the United Nations/World Health Organization (FAO/WHO) was compared with that of the grown plants. Treated leachate can increase plant nutrient content.
