“…They found slightly higher microbial activity in soil after SS application. Based on the results of Sastre et al (1996), SS had a positive influence on microbial activity in soil and due to this process on the organic matter decomposition as well. According to Tabatabai and Chae (1991) SS has also more optimal C:S ratio for organic compounds mineralization compared to FYM.…”

The aim of this work was to evaluate the changes of different soil sulfur forms during long-term field experiments supplied with sewage sludge (SS), farmyard manure (FYM) or mineral fertilizers. The experiment was established at three different sites with the crop rotation of potatoes, wheat and barley. Fertilizing system was based on the same nitrogen dose per the whole crop rotation. Soil samples from the beginning of the experiment (1996) and at the end of each crop rotation were analysed after all three crops harvest. Similar tendencies of changes in water extractable (S w ), adsorbed (S ads ), 1 mol/L HCl estimated (S HCL ) sulfur and their sum of (∑S) related to the fertilizing systems were observed among all studied sites. A decreasing tendency of ∑S in soil was observed during the experiment (except for the year 2005). The biggest decrease was always visible compared to control treatment. Mineral fertilizers (S added with superphosphate) appeared to be the best source of S HCL . Application of SS increased the S w content in soil samples after potatoes harvest, whereas a decreasing tendency among the following crops was visible. Contents of other S forms (S w at control, FYM and mineral fertilizers included) were usually balanced during the crop rotation.

“…The following morning, samples were thoroughly crushed with pestle and mortar and passed through a \ 2 mm sieve. Each sample was analysed in triplicate (control, sub-samples 1 and 2) (Sastre et al 1996) and for each sample, three types of enzymes were investigated, namely b-glucosidase, alkaline phosphatase and urease. Briefly, the estimation of b-glucosidase was based on the determination of the released p-nitrophenol, after the incubation of soil with p-nitrophenyl glucoside solution for 1 h at 37°C (Dick et al 1996).…”

Past mining activities in Swaziland have left a legacy of abandoned mine sites (iron ore, asbestos, diamond and coal mine dumps), all of which have not been reclaimed. These sites were recently (2013) considered by the country's wastewater treatment authorities as suitable places where biosolids can be applied, firstly as a biosolids disposal alternative and, secondly, as a strategy to accelerate mine soil remediation through phytostabilization. In order to understand the effects that this might have on mine soil conditions and microbiota, two (2) plant growth trials were conducted in biosolid-treated iron mine soils and one (1) trial on undisturbed soil, under greenhouse conditions, for twelve (12) weeks. According to the results obtained, the combination of biosolids and plants led to significant improvements (p \ 0.05) in parameters related to soil fertility. Significant increases (p \ 0.05) in alkaline phosphatase, b-glucosidase and urease soil enzyme activities were also observed. Copper and zinc were significantly (p \ 0.05) increased (Cu from 17.00-50.13 mg kg ); however, these sludge-derived metals did not affect enzyme activities. Improvements in soil physicochemical conditions, organic matter-metal complexes, effects of plants on metals and the essentiality of Cu and Zn to soil enzymes were thought to have masked the effects of metals. Increases in soil enzyme activities were considered to be indicative of improvements in the quality, fertility health and self-purification capacity of iron mine soils due to synergistic effects of biosolids and plants.

“…L'ajout de matière organique dans les sols agricoles représente une source d'énergie, de carbone, de nutriments divers pour les microorganismes du sol, d'autant plus favorable que les sols sont pauvres en éléments et limitants pour la croissance des microorganismes. Une augmentation de la biomasse microbienne et du nombre de bactéries hétérotrophes cultivables en réponse à un ajout de matière organique a déjà été rapportée (Sastre et al, 1996;Albiach et al, 2000;Garcia-Gil et al, 2000). Cette augmentation est généralement proportionnelle à la quantité de matière organique apportée (Albiach et al, 2000;Garcia-Gil et al, 2000 ;Saison et al, 2006).…”
