“…Biomass tended to increase with higher amended doses, especially in the roots. Applying sewage stimulated O. compressus L. growth in degraded Alfisol soil, and this agrees with results of other crops in different environments (Hernández et al, 1991;Marambio and Ortega, 2003). Figure 1 shows phosphatase acid enzymatic activity.…”

“…Subsequently, a representative sample was obtained from each one for chemical characterization (Table 1), which was performed with compound samples using the Sadzawka et al (2006) soil methodology and methods recommended by Sadzawka et al (2005) for (Table 2) were performed in the Environmental Chemical Laboratory of the Universidad de Concepción (accredited ISO 17025). Heavy metals can affect the soil's microbial biomass and enzymatic activities (Hernández et al, 1991) although the analyses indicated that these sludges complied with national and international standards. mo with soil moisture at 60 to 70% field capacity, and environmental temperature between 7 and 10 ºC.…”

“…Soil microorganisms are important in a degraded soil recovery process because they stimulate plant growth through substances, such as hormones and vitamins, which improve structure, reduce erosion, and improve nutrient availability (Waldrop et al, 2003). According to the reported information, using sewage sludge as fertilizers and/or organic regenerators is an interesting option that adds valuable organic components and nutrients (Hernández et al, 1991).…”

There are few studies about the impact of sewage sludge on the biological properties in Alfisols of the Chilean Coastal Range drylands. Hence, the objective of this study was to evaluate its effect on the microbial respiration and enzymatic activities of a degraded Alfisol located in the Bío Bío Region (Chile) that was cropped with yellow serradela (Ornithopus compressus L.). Sludge was added to the soil at rates of 15, 30, and 60 t ha -1 ; he following treatments were defined: L15-P = 15 t ha -1 sludge + O. compressus; L30-P = 30 t ha -1 sludge + O. compressus; L60-P = 60 t ha -1 sludge + O. compressus; L15 = 15 t ha -1 sludge; L30 = 30 t ha -1 sludge; L60 = 60 t ha -1 sludge; CP = non-amended soil, cropped; and C = non-amended soil, no crop. Soil microorganism activity was evaluated by respirometry. Hydrolytic enzyme activity representative of soil C, N, and P cycles was determined. Crop phytomass development was also evaluated. The amount of C-CO2 produced by soil microorganisms was directly proportional to the dose of amended sludge (p ≤ 0.05). Similarly, greater β-glucosidase, urease, and acid phosphatase were more active at 60 t sludge ha -1 . However, both respiratory and enzymatic activities were greater (p ≤ 0.05) in treatments with sludge-amended soil cropped with O. compressus. This greater activity was notorious when the legumes achieved greater phytomass development, thus highlighting the root's stimulating effect on soil biological activity.

“…Biosolid application has been shown to increase plant biomass in sunflower (Morera et al 2002), maize, barley (Hernandez et al 1991), and cotton (Tsakou et al 2001) and decrease in plant biomass in spinach (Singh and Agrawal 2007) and lettuce (Moreno et al 1997). Logan et al (Logan et al 1997) observed a plateau-type response in the accumulation of Cd, Cu, and Zn concentrations in corn and a linear response in lettuce plants.…”

The accumulation of metals and nutrients in biosolid-amended soils and the risk of their excess uptake by plants is a topic of great concern. This study examines the elemental uptake and accumulation in five vegetable plants grown on biosolid-applied soils and the use of spectral reflectance to monitor the resulting plant stress. Soil, shoot, root, and fruit samples were collected and analyzed for several elemental concentrations. The chemical concentrations in soils and all the plant parts increased with increase in applied biosolid concentrations. The Cu and Zn concentrations in the plant shoots increased in the order of collard

“…A dinâmica dos metais pesados no sistema solo-planta é influenciada pelas características e propriedades dos solos, e pelo comportamento das diferentes espécies vegetais (Cabrera et al, 1988;Hagemeyer & Waisel, 1989;Hernandez et al, 1991). Entretanto, como as doses de micronutrientes utilizadas são sempre pequenas, a adição de metais pesados, via resíduo, pode não ser expressiva, dependendo da composição química desses materiais.…”

O objetivo deste trabalho foi avaliar o pó de forno elétrico (PFE), resíduo da indústria siderúrgica, como fonte de micronutrientes e contaminantes para o milho, em condições de casa-de-vegetação. Utilizou-se como substrato um Cambissolo álico, onde foram aplicados três níveis de calcário (0, 2 e 4 t ha-1) e cinco tratamentos: sem fornecimento de micronutrientes (testemunha), com fornecimento de micronutrientes via fontes de reagentes p.a., e com 250, 500 e 1.000 kg ha-1 do pó de forno elétrico. A produção de matéria seca só variou significativamente na presença de calagem. Os tratamentos com PFE proporcionaram aumentos na produção de biomassa em relação à testemunha, porém apresentaram resultados inferiores aos proporcionados pela aplicação de micronutrientes via fontes p.a. Não ocorreram diferenças entre os tratamentos na produção de matéria seca do milho com a adição de doses crescentes de PFE. O PFE atuou como fonte de micronutrientes, principalmente de Zn e de Fe. A solubilidade do PFE é sensivelmente maior em condições de maior acidez do solo. A presença de Cd e Pb foi detectada na matéria seca da parte aérea. O risco de contaminação do solo e dos alimentos por metais pesados presentes no PFE pode limitar seu uso agrícola como fonte de micronutrientes.
