This research deals with the effects of soil amendment with sewage sludge compost (SSC) on the accumulation of microelements (Cu, Zn, Mn, Ni, Fe) in plants—white mustard (Sinapis alba), triticale (Triticale) and white lupine (Lupinus albus)—cultivated on two contrasting soils (light vs. medium agronomic class). Additionally, the influence of experimental factors on variability of the harvest index (HI) was determined for individual plants and micronutrients. A 3-year pot experiment was conducted and SSC at the rate of 6 t·ha−1 was applied into the soils. These changes were determined by ANOVA and subject to regression analysis and subsequently visualized. The study clearly demonstrated that SSC as an organic fertilizer had a significant, but weak effect on the microelements level variability in the shoots and grains of plants cultivated in crop rotation. Regardless of the experimental factors, on average, the plants accumulated higher amounts of Cu, Zn and Mn in the grains, and Fe and Ni in the shoots. Harvest index values confirmed the significance and variable translocation of microelements within plant organs. The influence of SSC on micronutrient contents in plant organs was more significant in the case of medium soil.

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.

The floricultural industry is always searching for new and low-cost materials to use as substrate for crop growth and development. Sewage sludge is an organic solid waste from sewage treatment and it has a good potential to be used as an organic fertilizer and/or substrate conditioner. The research aimed to evaluate the rooting and growth of Codiaeum variegatum ‘Andreanum’ (red variety) and Codiaeum variegatum ‘Punctatum’ (yellow variety) cuttings cultivated in the potting media: PM1 - 100% commercial potting media used as control (CS), PM2 - 100% organic compost of sewage sludge + sugarcane bagasse (SSSB), PM3 - 50% CS + 50% SSSB, PM4 - 100% organic compost of sewage sludge + eucalyptus bark (SSEB) and PM5 - 50% CS + 50% SSEB. After 90 days of experimentation the chemical analysis of the substrate solution (pH, electric conductivity, P, K, Ca, Mg, S, Na, B, Cu, Mn and Zn) and number of shoots, shoot fresh and dry mass, plant cutting fresh and dry masses, root fresh and dry masses, total fresh and dry masses and, length of the largest root were analyzed. Our results showed that sewage sludge compost can be used as a substrate for rooting and growth of croton cuttings when mixed with commercial substrate. The use of the pure sewage sludge compound with sugarcane bagasse or eucalyptus bark prejudiced croton cuttings to root.

Sewage Sludge Compost

The aim of this study was to assess the effects of the addition of sewage sludge compost (SSC) on the properties of aeolian sandy soil by measuring electric conductivity (EC),pH value,bulk density,field capacity,total N(TN),total P(TP),organic matter (OM),available N,available P and available K.Seven treatments were included in this experiment,the SSC was applied at rates of 0,2,5,10,15,20,25 kg·m-1.The results showed that the physichemical properties changed greatly with the addition of SSC to the soil. As for physical properties of the soil, bulk density decreased gradually, the field capacity increased significantly compared with CK,As for chemical properties, pH changed inapparently, the concentration of OM and other nutrients were positive correlated with SSC dosages. It was concluded that the addition of SSC could enhance the soil’s fertility and improve the soil’s physical structure,it was an effective disposition way for sewage sludge to be used as the organic fertilizer in soil.

Composted sewage sludge can be applied to land to improve soil physical properties and supply nutrients. In this study we use the case of sewage sludge compost applied to the abandon mine located in the Taoyuan Village of Mentougou District of Beijing to supply and illustrate that a new way to improve the mine restoration soil which also could have serviceability to deal with the city sludge. Experimental results showed sewage sludge compost application produced positive effects on the nutrient contents of soil and increased with increasing fertilizing amount.Considering the heavy metals accumulation in mine soil and there availability for crops, the Zn and Hg should be played more attention on the sewage sludge compost application in abandoned mine.
