“…Shoots of Gudrun tend to be much more branched than shoots of Tora, making the correlation between shoot length and shoot dry weight weaker. For Tora relative leaf length seems to be a useful and simple indicator of stress, as previously suggested by Dimitriou et al (2006). However, this involves the use of control plants with low levels of stress for comparison.…”

“…This equation is valid for this site only, but gives a hint about plants being very important in managing nitrogen. Low phosphorus concentrations in landfill leachate have been identified as potentially responsible for lower growth when used for irrigation of willows (Alker, 1999;Dimitriou et al, 2006;Hasselgren, 2003), and therefore minimal phosphorus leaching can be expected after leachate irrigation. However, phosphorus retention was below 90% for all treatments and years (Table 3) and therefore not entirely satisfactory compared with results from similar studies (Hasselgren, 2003;Jonsson et al, 2006).…”

“…Similar systems have been tested in the UK, USA, Poland and elsewhere (Bialowiec et al, 2007;Godley et al, 2004;Jones et al, 2006;Zalesny and Bauer, 2007). Some scientific studies on the treatment efficiency of such systems show promising results but variable efficiency (Alker, 1999;Dimitriou et al, 2006;Watzinger et al, 2006). Studies from the UK have reported toxicity symptoms in willow plants irrigated by landfill leachate, probably due to its high ionic strength (Stephens et al, 2000).…”

“…The greatest phytoremediation levels are not necessarily connected with the highest biomass yield (Greger, Landberg 1999;Klang-Westin, Eriksson 2003;Zalesny, Bauer 2007b), and higher concentration of metals and nutrients is accumulated in the bark than in the wood tissue (Pulford, Dickinson 2005;Dimitriou et al 2006;Adler et al 2008). This should be tested in the future elemental analysis of the plant material.…”

Compost leachate is produced by conversion of municipal waste to compost. It contains significant amounts of organic materials, nutrients, soluble salts and small amounts of some heavy metals. Adding compost leachate to the soil can pollute it, and also improve soil fertility. In this study, we investigated absorption and growth performance of Populus deltoides under irrigation with leachate of the Compost Plant of Rasht. At the beginning of the growing season, in mid-March 2013, cuttings were processed from young, one-year-old seedlings of Populus trees in the greenhouse of the Safrabaste Poplar Research Station. Cuttings were planted in pots filled with loamy-sandy soil in the vicinity of the area with 40cm depth. Compost leachate was taken from a collection reservoir where leachate from the open composting of organic municipal wastes and various gardening and plant wastes had been collected. Five treatments were applied to plants: (C) tap water (control), (P) pure leachate, (3:1) three units (by volume) of leachate mixed with one unit of tap water, (1:1) and (1:3). The growth of tree diameter and height was measured bi-monthly. Aboveground (stem, branches and leaves) and root biomass was inventoried at the end of the growing season. Concentration of elements was determined every three months. Overall, growth parameters in 1:1 and 1:3 treatments were similar together and there were no significant differences between them (P < 0.05). Pure treatment had minimum growth because of a high concentration of solvable salts in leachate such as sulphur that causes salinity and high EC in soil. Treatment1:3 exhibited the greatest overall aboveground and root dry mass. Total aboveground dry mass of leachate treatments and water was 202.25 and 47.58 g, respectively.

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.
