Soil enzymes as indicators of long-term sewage sludge compost application

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.

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.

Plot Experiment

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.
