“…Some of the plant nutrients contained in sewage sludge, mainly P did not show a tendency to move down through the soil column, an indication that sewage sludge should be incorporated into the soil to improve nutrient bioavailability. Similar results have also been reported on various plants regarding amending soils with biosolids (Gavi et al, 1997;Sonmez and Bozkurt, 2006).…”

ABSTRACT:Reuse of domestic wastewater that does not contain heavy metals or pathogenic microorganisms, as irrigation water is a significant method in terms of water conservation all around the world. In this field trial which was conducted over two years, the domestic wastewater (DW) of Muğla City after being alkaline stabilized was used to irrigate maize plant for silage and the interaction of soil and water was also controlled during the trial. Alkaline stabilized domestic wastewater (ASDW) was applied in four different doses as 150 ton ha -1 , 300 ton ha -1, 450 ton ha -1 and 600 ton ha -1 . During the vegetation stage, periodic physical observations were done and soil and plant samples were collected in order to evaluate the state of nutrition and effects of alkaline stabilized domestic wastewater. In the analysis, it was determined that pH and salt content of the soil didn't change and the contents of Ca and Mg elements increased. Chemical composition, in vitro metabolic energy values and pH of silage feedstuffs samples were investigated. In comparison with control, alkaline stabilized domestic wastewater treatment increased dry matter, crude protein, crude fat (as ether extract) and thus the metabolic energy (ME) content of feedstuffs. For silage yield, crude protein and metabolic energy, the best results were obtained with 600 ton ha -1 application. According to the results, after alkaline stabilized domestic wastewater application to soil, which is a finite natural resource, soil was not negatively affected, and the quality and physiological features of maize for silage were affected affirmatively. In conclusion, alkaline stabilized domestic wastewater can be reused as a source of irrigation water and fertilizer for agricultural purposes.

Muğla İlinde iki yıllık tarla denemesiyle kireçle stabilize edilmiş kentsel atık sular silajlık mısır bitkisinin sulanmasında kullanılmış ve deneme süresince toprak ve su etkileşimleri kontrol altında tutulmuştur. Atık su; 150 ton ha -1 , 300 ton ha -1, 450 ton ha -1 ve 600 ton ha -1 olmak üzere 4 farklı dozda uygulanmıştır. Vejetasyon süresince uygulanan atık suların toprağa ve bitkiye olan etkisini değerlendirmek amacıyla periyodik olarak toprak ve bitki örnekleri toplanmış ve fiziksel gözlemler yapılmıştır. Analizler sonucunda toprağın pH ve EC değerlerinin değişmediği ancak Ca ve Mg kapsamlarının arttığı tespit edilmiştir. Silaj örneklerinin kimyasal kompozisyonu, in vitro metabolik enerji ve pH değerleri silaj öncesi ve sonrası ayrı ayrı olmak üzere değerlendirilmiş ve kontrol uygulamaları ile atık su uygulama grupları karşılaştırıldığında; kuru madde, ham protein, ham yağ ve metabolik ener...

“…In addition, according to Sonmez and Bozkurt, (2006) liquid biosolids applications increased organic matter, electrical conductivity, total N, available P, exchangeable K, total Cu, extractable Mn, Cu and Cd concentrations of topsoil. Extractable Fe, Cr and Zn and the total Cd, Cr and Zn increased in soil with added sludge.…”

“…The risk of heavy metal uptake by plants after soil application of SS has been of some concern ( Sönmez and Bozkurt , 2006; Singh and Agrawal , 2008; Rastetter and Gerhardt , 2015), though in recent years the heavy metal loading of SS has decreased substantially in Europe ( Amlinger et al, 2004). In the current study, Pb, Cd, and Ni concentrations in plant biomass were below detection limits, moreover, the concentrations of Cr were low ranging from 0.29 to 0.58 µg g −1 (Table 2).…”

Sewage sludge (SS) can be used as an alternative fertilizer in agriculture. It is normally broadcasted and plowed into soil, but it is not clear if it has a potential as a placement fertilizer. A rhizobox experiment was conducted to investigate the placement effect of SS and mineral nitrogen (N) fertilizer on shoot and root growth as well as nutrient uptake of spring wheat (Triticum aestivum L.). The treatments included localized SS, mixed SS, localized SS and ammonium, localized ammonium, and a control without addition of SS and ammonium to examine the effect of SS placement and, further, if ammonium co-localization would enhance the placement effect. The results show that SS fertilization improved soil N and P availability, which significantly increased plant N and P uptake and enhanced shoot growth, while root length was significantly reduced compared to the control. Localized SS increased root proliferation in the placement region, resulting in enhanced uptake of P from the SS patch compared to homogenous application. However, co-localized application of ammonium with SS significantly depressed plant shoot and root growth. Localized ammonium markedly restricted root proliferation in the placement region and reduced soil pH in both bulk soil and placement region, contributing to decreased nutrient uptake and plant growth.

“…Piccolo (1988), in the study of the effect of humic substances on the usefulness of heavy metals in the soil in the study of the addition of humic matter in the soil, all metals in soluble and exchangeable form has been found to effectively immobilize the further propagation of mineral soils. According to Sönmez and Bozkurt (2006) with their work with humic acid applications of heavy metals from waste bioavailability can be limited. Naik and Das (2007) reported the highest increase in DTPA-Zn content with 0.2% humic acid.…”

This study was conducted on the YYU campus area as a field survey, according to the randomized block experimental design carried out in three replicated. The yellow and orange marigold species with humic acids (HA0;0 kg HA da-1 , HA1;10 kg HA da-1 , HA2;20 kg HA da-1 , HA3;40 kg HA da-1) were used. At the end of the experiment, the soil samples taken from the field of study were analyzed organic matter, soil reactions, total salt content, lime content, nitrogen, phosphorus, potassium, calcium, magnesium, natrium, iron, manganese, zinc, copper, cadmium, nickel and lead contents. The increased humic acid applications have influenced pH (P<0.01), lime (P<0.01), organic matter (P<0.05) with phosphorus (P<0.01), iron (P<0.05), zinc (P<0.05) and nickel (P<0.01) contents. The effect variety (V) has been determined on the available of soil iron (P<0.01), zinc (P<0.01), cadmium (P<0.01), nickel (P<0.01), and lead (P<0.01) contents. The interaction of only affected the nickel (P<0.01) and zinc (P<0.01) contents. As a result, humic acid applications have an important and positive effect on many properties of soil.
