“…The pig manure has the largest salt content (EC value of the pig manure, straw and sludge was 3.04, 0.52, 0.47 dS m -1 respectively), so when applied to soil the EC increased the most. Similarly, Perez-Murcia et al (2006) reported that EC increased about four times when the sludge compost added to peat land. When mushroom compost was applied to farmland, soil EC also increased significantly because of the high concentration of Na in the compost (Courtney and Mullen, 2008).…”

To cite this paper: He, S., A. Li and L. Wang, 2016. Effect of sewage sludge and its biomass composting product on the soil characteristics and N2O emission from the tomato planting soil. AbstractIn this study, tomato plants were cultivated in the greenhouse in five consecutive experiments: fertilized with 800 kg N ha -1 fresh sludge (S-H), 400 kg N ha -1 fresh sludge (S-L), 800 kg N ha -1 straw composting product (VM-S), 800 kg N ha -1 swine manure composting product (VM-M) and no fertilization (CK), and the soil properties, inorganic nitrogen forms and N2O emission characteristics were investigated. The results showed that, treatments with composting product significantly increased the soil electrical conductivity (EC) (p<0.05), and the VM-M treatment exhibited the largest soil EC. With the addition of sludge and composting products, pH of soil increased significantly (p<0.05) and ultimately tend to be neutral, and the inhibitory effect of VM-M on soil acidification was better than VM-S. Soil NO3 -concentration increased significantly with application of sludge and composting, and the NO3 -concentration of each treatment decreased gradually with time. Most of the NO3 -was absorbed by tomato plants, partially leached from the upper soil layer to the lower. Most of the NH4 + was oxidized to NO3 -and partially absorbed by plants. With the equal application of inorganic nitrogen, the promoting effect on the tomato growth was VM-M>VM-S>S-H. In addition, the excess application of nitrogen fertilizer from S-H than S-L did not promote the growth of tomato markedly (p<0.05). Compared with the control, N2O emission from soil was significantly improved by sludge or biomass composting (p<0.05). The N2O emission from all treatments were focused on the first 20 days after fertilization, and the emission of soil N2O was S-L (0.76 kg N2O-N ha -1 y -1 ))

“…Uma das fontes de alteração está no aumento das concentrações de Níquel (Ni) no solo devido à utilização de biossólidos na agricultura, cujo uso também pode promover melhorias nas características químicas no solo (Corrêa et al, 2010;Rodrigues et al, 2011) proporcionando aumentos da produtividade de diversas culturas (Perez-Murcia et al, 2006).…”

A utilização de biossólidos industriais na agricultura pode proporcionar aumento de níquel no solo, porém sua biodisponibilidade é influenciada por diversos fatores e, muitas vezes, resíduos com elevados teores de níquel não estão associados à sua alta absorção pela planta. O objetivo foi avaliar a solubilidade do níquel no solo, sua biodisponibilidade e acumulação em plantas. O experimento foi conduzido em vasos em delineamento inteiramente casualizado com seis doses de níquel: 0, 9, 18, 36, 72 e 144 mg de níquel kg -1 de solo, via fonte orgânica (biossólido compostado) e mineral (cloreto de níquel) com 4 repetições. Utilizou-se um Cambissolo Háplico como substrato e o morangueiro como planta indicadora. Avaliaram-se os teores no solo pelos extratores: ácido nítrico + clorídrico concentrado (3:1), nitrato de cálcio a 0,5 mol L além, ainda, dos teores de níquel na raiz, coroa, parte aérea e fruto. As maiores e menores extrações de níquel no solo foram observadas pela aplicação da fonte orgânica e extração com o ácido nítrico e clorídrico concentrado e pelo nitrato de cálcio, respectivamente. Ambas as fontes aumentaram os teores de níquel nos tecidos avaliados, com menores aumentos para fonte orgânica. Os maiores teores foram observados em raiz e os menores em coroa.Organic compound with high levels of nickel and its bioavailability in soil-plant system A B S T R A C TThe use of industrial biosolids in the agriculture may increase nickel levels in the soil. However, bioavailability of nickel may be influenced by several factors and nickel-rich residuals are not often directly related to high absorption of this metal by the plants. This study aimed to evaluate the nickel solubility in the soil, its bioavailability and accumulation by the plants. An experiment was conducted using strawberries as experimental model. Those were planted in earthen pots filled with Inceptisol with four replications. A fully randomized design was developed and six doses of nickel were employed: 0, 9, 18, 36, 72 and 144 mg per kg -1 of soil. Two nickel sources were employed: composted biosolid (organic source) and nickel chloride (mineral source). Both soil and plant nickel levels (the latter including roots, crow, aerial parts and fruits) were evaluated by using the following extractors: nitric acid + hydrochloric acid solution (3:1), calcium nitrate solution (0.5 mol L ). The highest and lowest nickel levels were yielded by the use of organic source by the nitric acid + hydrochloric acid solution and calcium nitrate solution, respectively. Both organic and mineral sources increased nickel levels in the strawberries tissues, with small increases verified for the organic source. The highest levels were found in the roots whereas the lowest were obtained in the crow.Composto orgânico com altos teores de níquel e sua biodisponibilidade no sistema solo planta

“…For example, 30% of sludge is applied to agricultural land in Japan (Ito et al, 2000). In addition to N, sludges often contain micronutrients that could benefit crop growth (Abdou and El-Nennah, 1980;Perez-Murcia et al, 2006;Vazquez et al, 2003). However, metal loadings to soil from repeated sludge applications can cause reduced numbers of nitrogen fixing bacteria in soil (McGrath et al, 1988;McGrath et al, 1995) and result in a shortage of arbuscular mycorrhizal fungi (del Val et al, 1999).…”

Soil extracts are used to provide a measure of plant nutrient bioavailability, but their predictive capacity is variable. In a greenhouse experiment, soil was amended with sewage sludge from textile manufacturing wastewater. We investigated the correspondence between maize (Zea mays L.) shoot uptake and concentrations in soil extractions for plant essential micronutrients concentrated in the sludge: B, Cu, Mn, and Zn. Hot water extract was used for B, whereas diethylene triamine pentaacetic acid (DTPA) extract was used for Cu, Mn, and Zn. Separate pots with NH 4 NO 3 amendment, but no sludge, allowed comparison of soil micronutrient extraction and plant uptake under conditions of elevated mineral N fertility similar to those with sludge amendment, but in the absence of sludge. Addition of sludge did not change soil extractable concentrations nor shoot concentrations of B and Zn. B was ISSN 2157-6092 2014 www.macrothink.org/jee 34 abundant in the sludge but likely remained strongly bound as organic complexes, whereas the quantity of Zn was not high enough to register difference. Shoot Mn was increased by both sludge amendment and an NH 4 NO 3 effect, likely from pH decrease associated with nitrification of the ammonium in the sludge and in the fertilizer. DTPA-extractable Mn increased in sludge-amended plots. DTPA-extractable Cu increased strongly following sludge amendment, but, in contrast to Mn, shoot Cu concentration was not changed. Thus, selectivity of roots to avoid Cu is not revealed by DTPA. The correspondence between extraction-based estimation of availability and the actual plant uptake varies among micronutrients due to effects of soil conditions and selectivity of roots.
