Evolution of organic matter in full-scale composting plant for the treatment of sewage sludge and biowaste by respiration techniques and pirolisis-GC/MS Biores Technol. The Science of composting. The HA-CRM electropherogram shown similar profile to other soils HA, in similar experimental condition (He et al., 2010; de Moraes and Rezende 2008), suggesting that at this phase of the process the structural transformation in HA-like fraction were significant to perform the evolution toward similar soil HA characteristics. The results showed that the foliar application of the biofertilizer at the tillering stage produced the highest increase in grain yield (59.7 %, p < 0.10). BNGCq"E,x@%jP1ZBC9V;7 z:OrWR:VrpW`z[gp:"L20
Rgz?_FZ_qQGtXA#?fZe8 AbstractThe current study was conducted to assess whether organic fertilisation could replace mineral fertilisation in lettuce production without adverse effects on yield, quality, and postharvest behaviour. Effect of Composted Animal Manure as Fertilizer on Productivity of Azolla Pinnata Grown in Earthen Ponds. culated as percentage of the TOC, therefore, the % CHA correspond to the Humification index (HI) (Roletto et al, 1985). The success in compost and/or vermicompost application is based on the use of reliable criteria for testing compost stability and maturity. Geochem. Biores. 69, 350-357. TOC, TN (g kg-1) Different letters (a-c), for organic amendments, in the same column indicate significant differences (P< 0.05) according to Tukey test (For the statistical estimation the soil was not take into consideration). 2019 Aug 5;65(6):22-27. x^:;}Ske.~v\_W F~3X
<>/Border[0 0 0]/P 5 0 R>> Waste Manage. 9 0 obj FOIA 4 0 obj In this research,chicken, horse, sheep and rabbit manure from one of the farms inthe Belgorod region of Russia were analyzed, and the parameters of a biogas station for the processing of this raw material were calculated.The biogas yield of the substrates was determined using the Hohenheim Biogas Yield Test. The ratio (CHA/CFA) slightly decreases during the vermicomposting time, reaching a value of 1.5, suggesting a roughly reduction in the contents of molecules with a high degree of condensation and hu-mification, which could indicate that the earthworm activities led to a homogeny degradation of all types of C compounds without selectivity, however, maturity level reached do not decrease. Among the compost treatments, the crude protein content of K1 and K2 were higher than K0 and K3 (25.34 and 26.25 vs. 13.11 and 22.96%, respectively; p<0.01). As a result of this activity, 83% of the community has been able to make organic fertilizer based on rabbit dung and produce solid and liquid organic fertilizer products with different chemical compositions. <>/Border[0 0 0]/P 5 0 R>> *Corresponding author: *"Silvia Ceppi: sceppi@agro.unc.edu.ar.
