“…Oliveira et al (2002) showed that Cd, Cr, Ni and Pb concentrations in sugarcane leaves, stalks and juice were also below the detection limit of the methodology used, and that Cu and Zn contents in plants were not affected by successive waste compost applications. Melo et al (2002) and Anjos & Mattiazzo (2000) corroborate those findings. Values obtained in this experiment did not exceed limits considered toxic for maize plants: 6-20 mg kg -1 for Cu, 225-1200 mg kg -1 for Mn and 15-50 mg kg -1 for Zn (Malavolta, 1994;Raij et al, 1996).…”

Biosolids comprise organic matter and plant nutrients, but are also a source of heavy metals hazardous to soils, plants and humans. The aim of this work was to evaluate accumulation, movement in the soil profile and availability to maize plants of heavy metals in two oxisols amended with biosolids for five years. The experiment was carried out in Jaboticabal, SP, Brazil, under field conditions, using a split-plot design. Biosolids were added to the soils at four different rates, 0.0 (control with mineral fertilization), 2.5; 5.0 and 10.0 t ha -1 , dry weight basis, annualy for three years. In the fourth and fifth years, the 2.5 t ha METAIS PESADOS EM LATOSSOLOS TRATADOS COM BIOSSÓLIDO E CULTIVADOS COM MILHO EM EXPERIMENTO DE LONGA DURAÇÃORESUMO: O biossólido contém em sua composição matéria orgânica e nutrientes das plantas, mas também metais pesados danosos para solos, plantas e a saúde humana. O objetivo deste trabalho foi avaliar o acúmulo de metais pesados e sua mobilidade no perfil do solo, assim como a disponibilidade para plantas de milho cultivadas em Latossolo Vermelho distrófico (LVd) e Latossolo Vermelho eutroférrico (LVef) tratados com doses crescentes de biossólido durante cinco anos. O experimento foi conduzido em Jaboticabal, SP, Brasil, em condições de campo, utilizando-se delineamento de parcelas subdivididas com cinco repetições. Foram testadas quatro doses de biossólido: 0,0; 2,5; 5,0 e 10,0 t ha -1 (base seca) nos três primeiros anos. A partir do quarto ano a dose 2,5 foi substituída por 20,0 t ha -1. No quinto ano de experimentação amostras de solo foram obtidas nas profundidades 0-20 e 20-40 cm e analisadas para totais e extraíveis (Mehlich 1) de Cu, Mn, Ni, Pb e Zn. O biossólido aumentou os teores de Ni e Zn no LVef e Ni, Pb, Zn e Cu no LVd, mas os valores não ultrapassaram os níveis críticos legais. Os elementos geralmente acumularam-se na profundidade 0-20 cm em ambos os solos. Os teores de Pb e Ni nos grãos ficaram abaixo do limite de detecção da metodologia empregada. As concentrações de metais pesados na planta geralmente não foram afetados pela adição de biossólido. O extrator Mehlich 1 não foi eficiente para avaliar a disponibilidade de Ni, Mn e Pb para planta de milho. Palavras-chave: Mehlich 1, lodo de esgoto, milho, fitodisponibilidade

“…Also in this study, applied ASDW did not change pH and salt content of the soil, and it positively influenced the quality and nutritional status of silage maize. Similar results were obtained by researchers in other studies (Jarausch-Wehrheim et al, 2001;Melo et al, 2002). Moreover, according to the study of Tamoutsidis et al (2002), sewage sludge application increased soil organic matter content and soil concentrations of N, P, K, Ca and Mg.…”

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...

“…Sludge may be dried and incorporated with some carbonaceous materials to produce a suitable composted material for the use in the agriculture to increase the production and improve the soil properties. Chemical and biological compositions of sewage sludge depend on the wastewater composition [3]. Usually, it is rich in Organic Mater (OM) and plant nutrients such as Nitrogen (N), Phosphorus (P) and Calcium (Ca) [4] and can improve soil physical, chemical and biological properties, such as porosity, aggregate stability, bulk density, soil fertility, water movement and retention [5].…”

This paper determined cations and anions concentrations, Total Kjeldahl Nitrogen (TKN), and heavy metals content in sewage sludge collected from the drying beds of wastewater treatment plant in Gaza. The aim was to test the possibility of using this sewage sludge as an alternative source of mineral fertilizers. Many instruments were used in this work: flame photometry (K, Na), EDTA titration (Ca, Mg), the turbidity method ( )
