“…Thus, the application of sewage sludge compost improves the structure of sandy soil. The improved physical properties by organic matter addition are affected by increased microbial activity (Aggelides and Londra, 2000;Tejada and Gonzalez, 2006). Soil bacteria and fungal hyphae play a significant role by binding soil particles into aggregates (Miller and Jastrow, 2000;Ortas, 2002).…”

Studying the long-term effect of composted sewage sludge application on chemical, physical and biological properties of soil, an experiment was established in 2003 at the Research Institute of Nyíregyháza in Hungary. The applied compost was prepared from sewage sludge (40%), straw (25%), bentonite (5%) and rhyolite (30%). The compost was ploughed into the 0-25 cm soil layer every 3rd year in the following amounts: 0, 9, 18 and 27 Mg ha−1 of dry matter. As expected, the compost application improved the structure of sandy soil, which is related with an increase in the organic matter content of soil. The infiltration into soil was improved significantly, reducing the water erosion under simulated high intensity rainfall. The soil compaction level was reduced in the first year after compost re-treatment. In accordance with the decrease in bulk density, the air permeability of soil increased tendentially. However, in the second year the positive effects of compost application were observed only in the plots treated with the highest compost dose because of quick degradation of the organic matter. According to the results, the sewage sludge compost seems to be an effective soil improving material for acidic sandy soils, but the beneficial effect of application lasts only for two years.

“…Reports also suggest that production of organic acids and other anaerobic degradation products lead to the generation of foul odour and a decrease in pH (Tejada and Gonzalez 2007). The pH of the test compost was 6.7, an ideal property of the compost to be used to increase soil fertility.…”

“…HS are used as soil conditioners of natural origin that contribute to increasing the ionic exchange capacity of the soil, are a fundamental part of the regulatory absorbing complex of plant nutrition to the conversion of non-absorbable forms [23] and play an essential role in the availability of nutrients in soils for plants [24], favoring the transfer of micronutrients and increasing the water retention and the percentage of seed germination. HS also contribute significantly to the weathering of rocks and chemical agents [2], acting as adjuvants for the phytoremediation of contaminated soils and stimulating the development of microbial populations in soils [25,26].…”

Background:The objective of this research was to evaluate, in saline-sodic soils, the effect of the application of a low rank coal (LRC), lignite type, along with an inoculation of bacteria that release humified organic matter (HOM) from this type of coal. The soil microbial activity and related coal biosolubilization enzymes mediated by microorganisms were determined along with the chemical variables associated with saline-sodic soils with testing under controlled conditions in a greenhouse.Results: Adding 1 % LRC and the solubilizing coal bacteria: Bacillus mycoides, Acinetobacter baumannii and Microbacterium sp., to a saline-sodic soil led to an increase in the soil respiration, microbiological activity, cation exchange capacity, and activity of the enzymes LiP and Lac. A decrease in the electrical conductivity, sodium adsorption ratio and percent saturation of sodium, except pH, was found. Conclusions:The present findings suggest the possibility of using LRC as a possible organic amendment in salinesodic soil, where the microbial activity can take place to accelerate the biotransformation processes of LRC to contribute to the rehabilitation of these disturbed soils.
