“…This hypothesis is consistent with the findings reported by Lopez-Millan et al (2009) 64, 84, 47, 388, 100, 970, 321, and 662% in the highest rate of MWC application (Tables 7,8). The observed change in soil chemical characteristics is consistent with results reported by others (Bevacqua and Mellano 1994;Khoshgoftarmanesh and Kalbasi 2002;Maftoun et al 2004). The influence of N fertilization was only significant for soil salinity and the concentration of NO À 3 and Cl in the soil (Tables 6, 8).…”

“…Applied MWC had a suitable C:N ratio (15:1) ( Table 2) which could lead to the net mineralization of N in soil. Maftoun et al (2004) reported that consumption of MWC and poultry manure with low C:N ratios (12.8 and 7.6, respectively) significantly increased the concentration of N in spinach plants. Similar results were also reported by Lehrsch and Kincaid (2007) in field-grown corn.…”

Purpose Since simultaneous use of organic and mineral fertilizers on the basis of their chemical compositions can lead to better plant growth and soil fertility, the roles of municipal waste compost (MWC) and nitrogen (N) fertilizer on growth and mineral composition of tomato and some soil properties were evaluated under greenhouse condition. Methods Treatments involved four MWC rates (0, 1, 2, and 4% on the basis of soil dry weight) and four N levels (0, 50, 100, and 200 mg kg -1 soil). Red cloud variety of tomato was sown in treated soils and 9 weeks later dried plant shoots and soil sub-samples were subjected to analysis. Results Combined use of MWC and N led to better growth of tomato than sole application of either MWC or N fertilizer. Plant concentration and/or uptake of nitrogen, phosphorus, zinc, copper, iron, and manganese were increased by both MWC and N. The beneficial effect of MWC on nutrients uptake was more pronounced with N addition. Plant and soil concentrations of cadmium and lead were under the detection limit of atomic absorption spectrophotometer. Soluble salts, organic matter, sodium, chloride and DTPA-extractable zinc, copper, iron, and manganese in the soil were effectively increased with addition of MWC.Conclusions Due to high soil pH and calcium carbonate equivalent (CCE) values of the calcareous soil, MWC heavy metals had no hazardous effect on tomato and even played a nutritional role. The most important problem raised from MWC application was the accumulation of soluble salts in the soil which must be monitored when making repeated application of MWC over an extended period of time.

“…Improvement in biomass and yield of carrot and spinach in MSW compost amended soil in comparison to control soil was observed. Similar trend in these parameters have already been observed in rice (Bhattacharyya et al, 2003), spinach (Maftoun et al, 2005), strawberries (Hargreaves et al, 2008a), timothy and red clover, (Zheljazkov et al, 2006), wheat (Bar-Tal et al, 2004), and maize (Carbonell et al, 2011). Among the compost materials, yield and N uptake was the highest from ANC material (Table 3).…”

This study aimed to examine the effect of composting techniques of municipal organic solid waste (MSW) for (i) total carbon (C), nitrogen (N) losses, and changes in its chemical characteristics during composting phase and (ii) value of the composted materials as fertilizer when applied to vegetables. Treatments included: aerobic composting (AC), anaerobic composting (ANC), co-composting (CC) and open dumping (OD) for 4 months.During the composting phase, about 61, 50, 35, and 13% of the initial N was lost from CC, AC, OD, and ANC, respectively. The respective values in case of total C loss were 17, 13, 14 and 11%. After field application, about 41% of the applied organic N was mineralized from ANC material, whereas the respective values for OD, CC and AC were 25-26, 15-16, and 12-19%. Consequently, dry matter (DM) yield and vegetable N uptake from the resultant compost were in the order ANC>OD>CC>AC. Moreover, vegetable apparent N recovery (ANRf) was the highest from ANC (spinach: 36 and carrot: 45%) followed by OD (26 and 34%), CC (18 and 26%) and AC (18 and 24%) material. When composting N losses were taken into account during calculations, about 31-39, 17-22, 9-10, and 7-12% of the N collected from filth depots ended up in plants from ANC, OD, CC and AC, respectively. We concluded that ANC results in least C and N losses during the composting phase and greatest N mineralization in the soil, which enhances vegetable yield, N recovery and thereby the N cycling through waste-soil-plant continuum.

“…In particular, the effect of different kinds of municipal solid waste (MSW) composts has been studied for their capacity of increasing metal availability in soil and their uptake by plants (Maftoun et al, 2004;Murphy and Warman, 2001;Pinamonti et al, 1999;Sebastiao et al, 2000;Warman and Rodd, 1998;Zheljazkov and Warman, 2004a,b).…”
