Organic wastes treated, used on agricultural land, can replace inorganic fertilizers, due to physical and chemical properties that improve soil and crop quality on long-term. In this study, was used biochar produced from sewage sludge, compost obtained from cattle manure, and mixtures made from biochar-compost in different concentration, at 5 t/ha and 30 t/ha, application rates. The aim of the study is to determine the influence of this organic wastes on the heavy metals bioavailability in greenhouse conditions and on Folsomia candida and Eisenia Andrei, used as test organisms under laboratory conditions. Compared to control variants, the use of biochar mixed with compost in different concentration at 5 t/ha and 30 t/ha, application rates, in a greenhouse experiment did not significantly affect the concentrations of heavy metals (Cu, Cd, Zn and Pb). Reproduction of collembolans has not been influenced by increasing application rate of the mixtures, and by concentrations of biochar or compost. The earthworms recorded weight losses, only in the experimental treatments with sewage sludge biochar used in different concentrations, at both application rates.

“…High rates of carbon loss from the breakdown of organic materials led to an increase in the concentration of phosphorus. Compost with a high TN content may have an elevated TP content due to increased microbial activity to break down P elements [14].…”

Compost has a critical role in preserving and conserving soil health and increasing soil fertility, both of which are essential for sustainable agricultural systems. The purpose of this research was to evaluate the efficacy of effective microorganisms (EM) in composting vegetable waste (VW), fruit waste (FW), and mixed food waste (MFW) using the Takakura Composting Method. During the 30-day composting period, nutrient content, including total nitrogen (TN), total phosphorus (TP), potassium (K), carbon to nitrogen (C/N) ratio, pH, and phytotoxicity as measured by germination index (GI), were evaluated. The compost quality index (CQI) was also used to evaluate the quality of the compost. The results showed that all VW, FW and MFW had pH values, TN, TP, K and C/N ratios that were within the acceptable range for mature and high-quality compost. The GI of VW and MFW were both above 80%, while FW’s GI was slightly phytotoxic at 79.3%. Based on the CQI score, MFW was found to be a very good compost variant, trailed by VW and FW. The results show that EM can accelerate the production of high-quality compost, which benefits conservation efforts.

“…The sewage sludge biochar was obtained by the slow pyrolysis process at 500ºC and the cattle manure compost was obtained by the passive composting method in static pile [19], for 2 years. The description of the method of obtaining these treated organic wastes is mentioned in the previous articles [20,21].…”

Organic wastes have been used in agriculture many years ago, due to its capacity to improve soil quality. The manure was used before the occurrence of chemical fertilizers and treated / untreated sewage sludge, started to be used as a fertilizer a few years ago. The aim of the study is to evaluate the organic matter, organic carbon, organic content and soil composition, after application in greenhouse conditions, of mixtures made from sewage sludge biochar and cattle manure compost. The biochar and compost used in different concentrations, at 5 t/ha and 30 t/ha, application rates, in greenhouse conditions, for a period of 90 days, improved organic matter, organic carbon and organic content from the soil used in experiment. The sewage sludge biochar and the cattle manure compost had similar effects on the parameters determined in the study. Organic and inorganic soil components, identified by the ATR-FTIR method, have not been modified by application of sewage sludge biochar and cattle manure compost.
