“…Other authors have demonstrated improvement of pine growth following application of organic amendments: P. sylvestris (Selivanovskaya and Latypova 2006), P. radiata Wang et al 2004) and P. halepensis (Bastida et al 2007). In the present study, the growth of P. caribaea was low in the control plots, indicating that this low-nutrient soil was not suitable for the natural development of this species at this site.…”

“…Although the control plot presented higher pine densities, mortality was higher but decreased when the soil was amended. Selivanovskaya and Latypova (2006) showed that sludge application decreased the mortality of Pinus sylvestris. However, increased mortality has been observed for P. echinata and P. taeda (Berry 1977) and adult P. caribaea (Watanabe et al 2009).…”

“…Previous studies have demonstrated that sewage sludge enhances plant re-colonisation of former mine sites (Rate et al 2004), post-fire sites (Larchevêque et al 2008) and industrial sites (Cox and Whelan 2000). Moreover, sewage sludge application in forestry sites led to a significant increase in the production of trees such as Pinus radiata Wang et al 2004), P. halepensis (Fuentes et al 2007), Quercus ilex, P. pinea (Larchevêque et al 2006) and P. sylvestris (Bramryd 2002;Selivanovskaya and Latypova 2006). This use of sludge, rather than for landfill or incineration, presents all the advantages of recycling nutrients.…”

Abstract. Soils from New Caledonia typically present poor nutrient content and large quantities of heavy metals such as nickel, chromium and cobalt, resulting in slow plant development. We evaluated the impact of sewage sludge application (0-30 t dry weight (DW) ha -1 ) on the passive revegetation of a former pine plantation. The spontaneously regenerated plant cover was mainly represented by the dominant Pinus caribaea, a shrub (Sannantha leratii), and a grass (Costularia comosa). The density of pine seedlings was significantly higher in the moderately amended zone (1.2 and 0.2 pines m -2 for 0.5 and 30 t DW ha -1 respectively). The same tendency was observed for S. leratii, but for C. comosa, no net change was observed. With no amendment, after 5 years many species were present, although aboveground biomass (0.3 kg m -2 ) was low, whereas, with sludge amendment, aboveground biomass was high (5 kg m -2 ) but diversity low. Amendment increased pine tree heights from 0.15 to 3.92 m with increased amendment from 0 to 30 t DW ha -1 . The uptake of nitrogen (N) by pine trees was also improved with sludge supply, as was the uptake of phosphorus (P). Regarding S. leratii, N and P levels were highest at the sludge dosage of 2 t DW ha -1 . Carbon storage in P. caribaea biomass increased from 0.40 to 180 kg m -2 with increased amendment applied. Five years after spreading at the highest amendment levels, available soil P remained enhanced. For heavy metal uptake by pine trees, no significant effect of sewage sludge was observed. The optimal dosage to stimulate biodiversity was 0.5-2 t DW ha -1 but maximal biomass was reached at 8-30 t DW ha -1 .

IntroductionA variety of wastes generated through different agricultural and other activities in our day to day life including crop residues in the form of straw, stover, husk, biomass of uncultivated plant species and weeds, forest biomass; animal wastes and by products like dung, urine, bones, fish processing wastes and human habitation wastes like garbage, sewage and sludge etc. (Table 1). Crop residues are abundantly generated in large quantities during crop cultivation. After harvesting the economic part(s) the plants are considered as wastes and are dumped on field side in mound. These accumulated wastes left on the field side causes major unpleasant odours and create disposal problems. They also create environmental problems like occupying vast area, spreading foul odours and forming breeding home for most of the pathogenic microorganism and mosquito vector. Furthermore they are often source of contamination of ground water. However, most of these potentially nutritious wastes are recyclable organic and good source of organic carbon. These huge inexpensive nutrient source or otherwise unused organic waste can be utilized for recycling as valuable resources. Considering growing deficiency of plant nutrients in crop field, higher cost of synthetic fertilizers and poor efficiency of chemical fertilizer, the organic wastes recycling for plant nutrient supply is becoming more essential for replenishment of plant nutrients, sustaining soil health, reducing the pollution problem and creating employment opportunities, which is now being increasingly recognized as a strategy for sustainable crop production. The organic wastes generally showed no adverse effects on crop yield, soil fertility or biological activity, but rather a stimulation of some properties, by reducing dependence on off-farm inputs and creating more balanced nutrient and energy flows, ecosystem resilience is strengthened, food security is increased and additional income are generated [1]. Tandon [2] stated that a sizeable proportion of nutrient needs of agriculture, horticulture, forest and aquaculture can be met through appropriate recycling of a number of wastes and by-product. With the changing scenario recent years have witnessed a renewed interest for sustainable crop production by revitalizing and restoring the soil fertility and reviving the microbial activity to make the soil lively and healthy (Table 1). AbstractEnormous amount of organic wastes are generated from plant, animals and industrial activities in day to day life. A considerable part of which remains unutilized and are either burnt or dumped nearby sites that create pollution, harbours pathogen for diseases and causes severe problem of disposal. Instead of disposing, it can be used as source of organic wastes and effectively recycled for the production of compost to meet the nutritional requirement of crops. Considering growing deficiency of plant nutrients in crop field, higher cost of synthetic fertilizers and poor efficiency of chemical fertilizers, the organic wastes recyc...

“…Soil properties such as active/free iron oxide ratio, isoelectric point (IEP), cation exchange capacity (CEC), and potassium-calcium cation exchange equilibrium have been related to OM content in Chilean volcanic soils (Escudey et al, 2004). On the other hand, the application of biosolids on land has been reported to have positive effects on fertility, crop yields (Andrés and Jorba 2000), and changes in chemical, physical, biological, and microbial properties (Selivanovskaya and Latypova 2006;Vaca-Paulín et al, 2006). In this context, the literature indicates that the addition of sludge provokes changes of the soil chemical characteristics, due to soil-sludge interaction, including pH, electrical conductivity, OM (%), P-Olsen and cation exchange capacity (CEC) (Singh et al, 2008, Adewole and Ilesanmi 2011, Yu et al, 2013.…”

The aim of this study was to evaluate the changes produced in the chemical, acid-base and structural properties of soil amended (biosolids) and humic acids HAs incubated at different times.In the current work the amendments were conducted with biosolids at different doses (30, 90 and 180 t ha -1 ) on Colina (CLN) soil for 1, 2, 4 and 6 months.The acid-base characterization of extracted humic acids (HAs) showed a slight impact on Atotal (total acidity, mEq g -1 ), at 30 and 90 t ha -1 while at 180 t ha -1 the greatest increase was observed from 10.5±1.61 (control) to 17.9±0.30 (6 months of incubation). without evolution over the incubation time. The Aphenolic (phenolic acidity, mEq g -1 ) acidity behaves similarly while Acarboxylic (carboxylic acidity mEq g -1 )) remains constant over time and applied doses. The application of 13 C solid state NMR technique revealed higher abundance of aromatic C (CLN 43.5%) over alkyl C (21.4%) compounds. Aromatic C presents a decrease at high biosolid doses, which occurs simultaneously with alkyl C increase when using the same surveyed doses. Therefore, it might be considered that through the addition of biosolids, components such as fatty acids, amino acids or paraffinic structures are incorporated. As a result of biosolids addition, carboxylic C content remains steady, which agrees with the Accarboxylic behavior previously determined.
