“…Spodosol treated with composted and 250 o C-dried biosolids produced lower yields at each harvest compared to the other three biosolids (Figure 1), but yields were more evenly distributed along harvests. Such a figure confirms the slow mineralization pattern of composted and thermally dried biosolids in sandy soils (Mbarki et al, 2008;Corrêa et al, 2012).…”

“…These biosolids were 2.0-2.3 times more effective to yield dry biomass than NH 4 H 2 PO 4 in an eight-week trial. The better performance of biosolids to produce plant biomass compared to chemical fertilizers has also been reported for other soils and crops (Fresquez et al, 1990;Silva et al, 2000;Fernández et al, 2008;Mbarki et al, 2008;Rivero et al, 2009). …”

Biosolids have been produced by various stabilization processes of sewage sludge, but little attention has been given to the effects of such treatments on their effectiveness to supply nitrogen for plant growth. Here, we investigated these effects by cultivating Lolium perenne (ryegrass) in two Australian soils, a sandy Spodosol and a clayey Oxisol. Biosolids stabilized by either aerobic digestion, composting, 250 o C heat-drying or solar irradiation of domestic sewage sludge were applied to soils at 10 increasing rates (0.25-8.0 dry Mg ha -1), and chemically fertilized soils were used as reference. Results showed that the stabilization processes affected biosolids-N agronomic rates and effectiveness to yield plant biomass, which was a function of organic-N contents mineralized in soils. In the short term, biosolids were from 1/5 (digested biosolids in Oxisol) to over twice (solar-irradiated biosolids in Spodosol) as effective as chemical fertilizer to produce a first single harvest. As long-term N-sources, they significantly increased the effectiveness to produce plant biomass, being from 2.0 to 4.1 times more effective than chemical fertilizer in Spodosol and 1.5-2.4 times in Oxisol. Biosolids could substitute for N fertilizer with similar or higher effectiveness to yield plant biomass, depending on the sewage sludge stabilization process, soil type and cultivation term considered. Therefore, the sound management of sewage products as N sources for crop production should consider the interaction among these factors rather than solely their N content.

“…Previous studies showed that soil properties, soil organic matter, and crop yield could all be improved by the addition of different types of compost (Darby, Stone, & Dick, 2006;Mbarki et al, 2008;Arthur, Cornelis, & Razaghi, 2012). In particular, improving the organic matter in soil is known to promote many benefits, including increased soil fertility, improved soil structuration, and reduced soil bulk density (Lal, 2014).…”

<b>Soil properties and cowpea yield after six years of consecutive amendment of composted tannery sludge

et al. 2016

View full text Add to dashboard Cite

ABSTRACT. This study evaluated soil properties and cowpea yield after six years of consecutive amendment of composted tannery sludge. The compost was applied annually at 0, 2.5, 5, 10, and 20 Mg ha -1 and at the end of the sixth year, the chemical and physical properties of the soil were evaluated using a randomized block design. The Cr, P, K, Ca, Na and organic C contents and the pH and cation exchange capacity increased linearly after six years of compost amendment. The soil bulk density decreased linearly while the aggregate stability index increased after compost amendment. As a consequence of the changes in the chemical and physical properties of the soil, cowpea yield showed a quadratic response to the tannery rates, with an estimated maximum cowpea yield at 8.3 Mg ha -1 . In conclusion, the soil chemical and physical properties improved after six years of composted tannery sludge amendment. However, the soil pH and the Cr and Na contents increased with composted tannery sludge amendment, which influenced the cowpea yield and resulted in a quadratic response to the compost.Keywords: waste management, soil fertility, soil quality.Propriedades do solo e produtividade do feijão-caupi após seis anos de aplicações consecutivas de lodo de curtume compostado RESUMO. Este estudo avaliou as propriedades do solo e a produtividade do feijão-caupi após seis anos de aplicações consecutivas de lodo de curtume compostado. Anualmente, o composto foi aplicado a 0, 2,5, 5, 10 e 20 Mg ha -1 e no sexto ano as propriedades químicas e físicas do solo e a produtividade do feijão-caupi foram avaliadas em experimento de blocos casualizados. Cr, P, K, C orgânico, pH, Ca, Na, e a capacidade de troca de cátions aumentaram linearmente após seis anos de aplicação do composto. A densidade do solo diminuiu linearmente enquanto a estabilidade de agregados aumentou após a aplicação do composto. Em consequência das mudanças nas propriedades químicas e físicas do solo, a produtividade do feijão-caupi apresentou resposta quadrática às doses de lodo de curtume compostado com máxima produtividade estimada encontrada na dose de 8,3 Mg ha -1 . Em conclusão, as propriedades químicas e físicas do solo melhoraram após seis anos de aplicação do lodo de curtume compostado. Entretanto, o pH do solo, bem como os teores de Cr e Na aumentaram com aplicação do lodo de curtume compostado e estes parâmetros influenciaram a produtividade do feijão-caupi que apresentou resposta quadrática.Palavras-chave: manejo de resíduos, fertilidade do solo, qualidade do solo.

“…Alfalfa belongs to perennial leguminous herb, which is the most wildly planted forage in the world. In recent years, alfalfa has been extensively used to contrast the toxic effects of variety heavy metals, such as cadmium, lead, chromium, nickel, zinc, and cobalt, upon its growth or nutrient uptake [12][13][14][15]. Among a variety of higher plants, vanadium is relatively highest in legume [5].…”

In order to characterize uptake of vanadium in alfalfa grown in vanadium-cadmium (Cd)-contaminated soil, 104 soil samples and 94 plant samples were collected from pot experiment. The results showed alfalfa had strong metal adaptability (up to 400 mg kg(-1)) and high accumulation (up to 3,440.14 mg kg(-1)) of vanadium. Root had higher contents and better absorption to vanadium than overground part. Moreover, both root and overground part had direct correlation with vanadium in soil, especially with the sum of first three fractions and reducible fraction. With the increasing of vanadium, higher concentration of Cd may inhibit the absorption of vanadium in alfalfa.
