Due to the increasing number of sewage cleaning plants, the amount of sewagesludge also increases. We have to solve the environmentally sound disposal of thesludge. Results of many experiments show that sewage sludge and sewage sludgecompost can be recycled as nutrient suppling material in agriculture. Municipalsewage sludge compost could cause the occurrence and accumulation of toxicelements in the soil. A small-plot experiment with sewage sludge compost wasestablished in the spring of 2003. The applied compost contains 40% sewagesludge, 25% straw, 30% rhyolite, 5% betonite. The small-plot experiment was retreatedin the autumn of 2006, 2009, 2012and 2015. There are 4 treatments in fiveblocks, where the sewage sludge compost was applied at a rate of 0, 9, 18 and 27tha-1 and then ploughed into the soil. Triticale as autumn cereal, maize and greenpea as spring crops were sown in crop rotation every year. Plant samples werecollected before harvesting. In this paper the results of crop yield between 2010-2012 are presented. Crops of triticale and maize were higher in the treated plotsthan in control one in 2010 and 2011. Treatment effect was not observed on greenpea yield.The results show that the effect of applied compost doses depends onplant species and time. Our aim is to maintain this unique long-term experiment forstudying the composted sewage sludge as a nutrient and organic matter source,applying it similarly to the farmyard manure.

Compost Extract

Nitrogen plays significant role in the life of plants, it could be the main limiting factor of plant growth. Sustainable plant nutrition pays attention to satisfy the plants’ nutrient demand without chemical fertilizers, e.g. by bounding the atmospheric nitrogen. The nitrogen fixing organizations play important role in supplying plants with nitrogenbecause the N2-fixingbacteria can fix high amounts of nitrogen.Many effects of the sewage sludge compost extracts is known in the literature. We studied the effect of sewage sludge compost water extract in laboratory conditions on the growth of Rhizobium spp. isolated from green pea, while in a small plot experiment thepea-Rhizobium symbiosis were studied on sandy soil in the Nyírség region. The extract was produced under aerobic conditions. The compost extract was applied before and/or after sowing. In the laboratory experiments we used the sterile version of extract, in different doses.In our work we present the effect of compost water extract on the number of green pea roots nodules, dry weight of the plant and reproduction of the Rhizobium bacteria.

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.
