ABSTRACTThis study aimed to evaluate the chemical attributes of an Inceptisol cultivated with castor bean (Ricinus communis L.), variety ‘BRS Energia’, fertilized with sewage sludge compost and calcium (Ca) and magnesium (Mg) silicate. The experiment was conducted at the ICA/UFMG, in a randomized block design, using a 2 x 4 factorial scheme with three replicates, and the treatments consisted of two doses of Ca-Mg silicate (0 and 1 t ha-1) and four doses of sewage sludge compost (0, 23.81, 47.62 and 71.43 t ha-1, on dry basis). Soil organic matter (OM), pH, sum of bases (SB), effective cation exchange capacity (CEC(t)), total cation exchange capacity (CEC(T)), base saturation (V%) and potential acidity (H + Al) were evaluated. There were no significant interactions between doses of sewage sludge compost and doses of Ca-Mg silicate on soil attributes, and no effect of silicate fertilization on these attributes. However, fertilization with sewage sludge compost promoted reduction in pH and increase in H + Al, OM and CEC. The dose of 71.43 t ha-1 of sewage sludge compost promoted the best soil chemical conditions.

Abstract A single-factor field experiment was carried out at the Cultivar Evaluation Station in Szczecin-Dabie in 2008-2010. The soil on which this experiment was set up is formed from light loamy sand (lls). In respect of granulometric composition, it is classified to the category of light soils, of soil quality class IV b and good rye complex. In the experiment, compost produced with municipal sewage sludge by the GWDA method was used. This compost contained clearly more nitrogen and phosphorus in relation to potassium. The content of heavy metals (Cd, Cu, Mn, Ni, Pb and Zn) in composts did not exceed standards of the Regulation of the Minister of Agriculture and Rural Development (Official Journal of Laws No. 165, item 765 of 2008) referring to organic fertilisers. In the study design, the following fertilisation treatments were applied: I - carbonate lime (CaCO3) at a dose of 1.5 Mg CaO · ha-1, II - high-calcium brown coal ash at a dose of 1.5 Mg CaO · ha-1, III - municipal sewage sludge compost at a dose of 250 kg N·ha-1, IV - municipal sewage sludge compost at a dose of 250 kg N · ha-1 + high-calcium brown coal ash at a dose of 1.5 Mg CaO · ha-1 (1st year of study), V - high-calcium brown coal ash at a dose of 1.5 Mg CaO · ha-1 (1st year of study), and 0.75 Mg CaO · ha-1 in following study years each, VI - municipal sewage sludge compost at a dose of 250 kg N · ha-1 + high-calcium brown coal ash at a dose of 1.5 Mg CaO · ha-1 (1st year of study), and 0.75 Mg CaO · ha-1 in following study years each. In addition, mineral fertilisation was applied annually in the form of multi-component fertiliser Polifoska 20, complex fertiliser Polimag S and ammonium nitrate. A test plant was perennial grass - Amur silver grass (Miscanthus sachariflorus). The obtained results show that Amur silver grass biomass contained on average the most nitrogen, ie 6.87 g·kg-1 d.m., in 2008, while the most phosphorus (0.39 g P·kg-1 d.m.), potassium (7.82 g K·kg-1 d.m.), magnesium (0.98 g Mg·kg-1 d.m.) and sulphur (1.19 g S·kg-1 d.m.) in 2010, whereas the most calcium ie 4.13 g Ca kg-1 d.m., in 2009. Significantly more nitrogen, calcium and sulphur was contained by Amur silver grass biomass from the objects where municipal sewage sludge compost had been applied without and with addition of high-calcium brown coal ash when compared to calcium carbonate or high-calcium brown coal ash being applied at a dose of 1.5 Mg CaO · ha-1. Differences in average phosphorus, potassium and magnesium contents in test plant biomass from particular fertilisation objects were not significant. The biomass of Amur silver grass contained significantly more cadmium, nickel, lead and zinc as affected by organic fertilisation without and with addition of high-calcium brown coal ash when compared with the objects where solely calcium carbonate or high-calcium brown coal ash had been introduced into soil. Differences in the average content of cadmium, nickel and zinc in test plant biomass from the objects fertilised with municipal sewage sludge compost without and with addition of high-calcium brown coal ash were not significant. The uptake of heavy metals by Amur silver grass biomass, ie its mean value of three harvest during three years of its cultivation, can be arranged in the following descending order of values: Zn > Mn > Pb > Cu > Ni > Cd. The degree of cadmium, copper, manganese, nickel, lead and zinc bioaccumulation in test plant biomass differed, depending on the fertilisation applied. The average degree of cadmium, nickel, lead and zinc accumulation after three study years was intense for all fertilisation objects, whereas average for copper and manganese.

Sewage Sludge Compost

Sewage dump is the main organic waste component accumulating in water treatment companies, and therefore the utilization of dump remains a burning issue. Fertilization is the most popular and cheapest way of using sewage dump a part of which is intended for agriculture in most European countries for composting purposes. Sewage dump or its compost are suitable for fertilizing the upper layers of the soil in cases the concentration of heavy metals is not greater than sanitarian standards can tolerate. The examinations were carried out using different waste dump rates from Vilnius water treatment facility in willow (Salix viminalis) grown cultivated fields. The analysis of the soil was executed after one and two years following the fertilization process. The obtained results indicate that waste dump is a valuable organic fertilizer which contains small amounts of heavy metals. Separate heavy metals migrate from sewage sludge compost to plants differently. It was noted that the concentration of heavy metals in willows was greater (except for Pb and Cd) than that in the soil.

Combined Application

The short-term effects of processed waste materials: sewage sludge compost (up to 0.5%), biochar made of paper sludge and grain husk (BC) (up to 2%) combined with plant growth-promoting rhizobacterial (PGPR) inoculum, on the fertility of acidic sandy soil at 65% of field capacity were tested in a pot experiment in separate and combined treatments. The soil pH, organic matter content, total and plant-available nutrients, substrate-induced respiration, arbuscular mycorrhizal fungal (AMF) root colonisation parameters and maize (Zea mays L.) biomass were investigated in experiments lasting two months. The positive priming (21% organic matter loss) induced by BC alone was not observed after combined application. The combination of compost and PGPR with 1.5% BC resulted in 35% higher P and K availability due to greater microbial activity compared to BC alone. Only compost applied alone at 0.5% gave a 2.7 times increase in maize biomass. The highest microbial activity and lowest AMF colonisation were found in combined treatments. In the short term the combined application of BC, compost and PGPR did not result in higher fertility on the investigated soil. Further research is needed with a wider range of combined treatments on acidic sandy soil for better understanding of the process.
