There is no aerobic fermentation pretreatment in the process of direct digestion of fresh cow manure by earthworms, which resulted in different properties of vermicompost compared with traditional treatment methods. However, there is limited knowledge on the properties of vermicompost in the direct earthworm digestion process. In the present study, a large-scale earthworm bio-bed was used to convert fresh cow manure into vermicompost, and then the physical, chemical, and microbial properties of the vermicompost were determined. To study the influence of mineral nutrient additions, vermicompost was mixed with vermiculite at a ratio of 4:1 (v/v), and was then used as the growth medium for capsicum seedlings. The results showed that nitrate nitrogen (243.39 mg/kg), ammonium nitrogen (50.38 mg/kg), total phosphorus (47.61 g/kg), available phosphorus (41.68 g/kg), catalase activity (2.17 mL/g·h), bacterial biomass (3.60 × 107 cfu/g), actinobacterial biomass (2.40 × 107 cfu/g), and fungal biomass (1.55 × 106 cfu/g) measurements were significantly higher in vermicompost than in the parent material. However, moisture (50.01%), electrical conductivity (2.07 mS/cm), total nitrogen (8.52 g/kg), organic matter (28.47%), and urease activity (0.63 mL/g·h) were significantly lower in the vermicompost compared to the parent material. The shoot and root morphological indices and the capsicum biomass accumulation measurements in the vermicompost treatments were superior to those found in the commercial peat medium (CK). Leaf expansion (14.83 cm), shoot height (24.20 cm), stem diameter (4.38 cm), leaf number (16.20 No.), root length (352.83 cm), root surface area (60.30 cm2), root diameter (0.61 mm), and root volume (0.92cm3) significantly higher in vermicompost-vermiculite mixed media with added urea (0.5 kg/m3), superphosphate (10.0 kg/m3), and potassium chloride (1.0 kg/m3) than in CK at the late seedling growth stage. The addition of mineral nutrients (NPK) had little effect on the physical properties of the vermicompost media, but it improved the available nutrients. In summary, fresh cow manure without pre-treatment can be processed into vermicompost using a large-scale earthworm bio-bed. Vermicompost could serve as an alternative for commercial peat media in the cultivation of capsicum plug seedlings, and the beneficial effects of adding NPK gradually emerged as the seedling growth time increased.","PeriodicalId":10714,"journal":{"name":"Compost Science & Utilization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/1065657X.2018.1434022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47127357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we characterized the transformation of phosphorus and other plant nutrients during aerobic composting of PL with sugarcane (SW) and cabbage waste (CW) for 120 d. Periodic samples were collected during composting and analyzed for total C, P (and its fractions), K, Ca, Mg, Cu, Fe, Zn, Mn, EC and pH. At the initial stage of composting (20 d), the P fractions varied in the order: water soluble P > NaHCO3-P (readily plant-available) > HCl-P (Ca+Mg-bound) > residual-P > NaOH-P (Fe+Al-bound). After 120 d, the order was HCl-P > residual-P > water-P > NaHCO3-P > NaOH-P. These variations suggested a transformation of labile Pi to more recalcitrant forms during composting. Water soluble P was the dominant fraction during the initial composting period. This declined progressively with time of composting, while the HCl-P increased, confirming the transformation of the more vulnerable water soluble P to the more recalcitrant HCl-extractable P. This indicated that the composting could be a useful way of managing manure for P stabilization and reducing its losses in runoff water following land application. The total C varied directly with the ratio of sugarcane and cabbage wastes in the manure but was inversely related to the duration of composting. Extractable K, Ca, Mg, and Na increased whereas trace elements concentrations decreased with time of composting. The higher availability of basic plant nutrients and reduced availability of heavy metals in the mature compost are valuable attributes for safe use in sustainable agricultural production.","PeriodicalId":10714,"journal":{"name":"Compost Science & Utilization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/1065657X.2017.1396268","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48822041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Composting is an organic waste treatment method that is cost effective and leads to resource recovery. Composting is considered an environmentally and agriculturally friendly method of sewage sludge utilisation. The objective of this study was to evaluate maturity of three composts prepared on the basis of sewage sludge mixed with structure-forming waste materials, such as pine bark, sawdust and wheat straw. The germination index (GI) was used to assess the maturity and phytotoxicity of composts at particular composting stages (initial, mesophilic, thermophilic, cooling, maturation). Cress seeds were used to determine the GI. The logistic model, which belongs to a broad class of generalized linear models, was used to analyze experimental data. Using this model the interesting probabilities (from the point of view of the experimenter) for the occurrence of a specific root length were determined. In addition, a model was constructed providing a dependence of probability on temperature. This work indicates a marked dependence between root length produced by cress seeds and the temperature of the composting process, which was closely related to the GI values. The longest plant roots, similarly as the highest GI values, were found at the lower temperature, which took place at the beginning and at the end of the composting process. Our findings suggest that the practical applicability of GI in the evaluation of compost maturity is limited. Additionally, the role of additional wastes being structure-forming agents in composted mixtures with sewage sludge was stressed as a sorption matrix for harmful substances released from sewage sludge.","PeriodicalId":10714,"journal":{"name":"Compost Science & Utilization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/1065657X.2017.1392907","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45336574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six composts and peat moss mixtures were tested, of which tomato waste compost suppressed V. dahliae, and turkey litter compost partially suppressed it. Reduced levels of symptoms and lower fungal colonization were detected in the xylem of eggplants planted in tomato waste compost, and these plants accumulated more dry matter and had higher chlorophyll content compared to other media. However, survival of conidia in tomato waste compost showed only a moderate decrease compared with a sharp decrease in other media, suggesting that conidial eradication cannot be proposed as the suppressiveness mechanism. γ irradiation of tomato waste compost and peat at 2.5 Mrad reduced microorganism density by four orders of magnitude, but irradiation of tomato waste compost did not reduce its suppressiveness of V. dahliae. Composts properties affected progress rate of VD in the xylem tissue of eggplant seedling.

All four TRT received equal plant—available N by supplementing the RM and CM with IN. Yield was measured by both machine-harvesting and hand-harvesting methods. Machine-harvested yield was similar among TRT for both years. Hand-harvested yield was lower for IN than RM in the first year, with similar yields among TRT in the second year. Due to drought, yields were considerably lower in the second year for all TRT. After 2 years, CM-H had higher soil P, K, Zn, and organic carbon concentrations than IN, with no differences among TRT for soil NO3-N, pH, or electrical conductivity.

It is concluded that EC of VC was the key factor for the positive increase of the productivity and quality of tomato and the salinity (EC at 3.52 dS/m) causing restriction of water to fruits that resulted in the increase of the total soluble solids in tomato fruit and without affecting yield reduction.","PeriodicalId":10714,"journal":{"name":"Compost Science & Utilization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/1065657X.2017.1344594","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46111780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
