Organic compost (OC) is a product of the decomposition of solid waste that can be used to correct the active acidity of the soil and also as a source of nutrients for plants. Thus, we sought to understand the influences of OC on soil pH during the incubation period, as well as its effects on the growth and development of the Acosmium nitens seedlings. The treatments consisted of natural soil (control) and three different dosages of organic compost (10, 30 and 50%). The effect of OC on soil pH was evaluated using a mixed design of repeated measurements, consisting of four treatments, six repetitions and four measurements during the study period. At 148 days after transplantation, the growth and development of Acosmium nitens seedlings were arranged in an completely randomized design, with four treatments and six repetitions, with the variables: total dry mass, dry aerial mass, dry root matter, diameter of lap, plant height, ratio of height/ diameter of lap and Dickson quality index. The OC significantly affected the active acidity of the soil, and caused significant interactions in the treatments during the incubation period of the substrate. The growth and development of plants were significant in relation to the dosages of OC in the substrate. Therefore, the OC from urban organic solid waste improved the degree of fertility and corrected the active acidity of the soil. The nutritional sufficiency for Acosmium nitens seedlings was achieved in the combination of 30% OC and 70% soil.

“…The availability of nutrients to plants is influenced by the amount and type of C in the growing substrate, whereas the humification process is affected by the quality of the C present in the compost [13,40,41]. In this respect, FTIR spectra have been widely used to investigate the changes to structural and functional HA groups associated with composting [42][43][44][45].…”

“…Humification is a process to which plant and microbiota residues are subjected in natural soils under the actions of microorganisms and other environmental factors [52]. Data from various spectroscopic and other analytical techniques (e.g., UV-Visible, synchronous fluorescence, FTIR, and 13 C-nuclear magnetic resonance) have shown that composting of organic wastes may be seen as an artificial process of humification. Indeed, these techniques coupled with principal component analysis [52,53] were able to group together composted materials and standards humic and fulvic acids samples from the International Humic Substances Society (https://humic-substances.org; accessed on 9 December 2021).…”

“…This is particularly important for pot-grown plants, as in this case, the growing substrates must sustain plants throughout their entire life cycle [10]. Organic amendments produced from agro-industrial wastes are well known to be rich in nutrients and to play vital roles in plant development [11][12][13][14]. However, studies are needed on the assessment of the chemical and physical properties of organic amendments, especially when they are used as growth media for potted spice plant species.…”

Spectroscopic and Physicochemical Characterization of Poultry Waste-Based Composts and Charcoal–Compost Mixtures for the Prediction of Dry Matter Yield of Giant of Italy Parsley

Plant growing substrates obtained by composting agro-industrial waste can serve as organic soil amendments. However, it is crucial to determine the maturity and quality of organic amendments before their application to soil. This study aimed to evaluate the suitability of compost obtained from poultry wastes combined with five different vegetal residues (tree trimmings, sugarcane bagasse, sawdust, cotton residues, and Napier grass) as growth media for container-grown Giant of Italy parsley. Fourier-transform infrared and laser-induced fluorescence spectra were used to characterize the humification extent in composts before and after the addition of charcoal at five inclusion rates (0%, 15%, 30%, 45%, and 60%, weight basis). Spectroscopic measurements identified absorption bands between 1625 and 1448 cm−1 specific to each of the 25 organic amendments evaluated. The most suitable amendments (composts made from sawdust and sugarcane bagasse) were associated with O–H stretching of phenols and aromatic rings. Charcoal addition to composts changed some of their physical characteristics, leading to increased nutrient availability in some cases. Experimental and calculated dry matter yield were compared via multiple linear regression and simple non-linear regression as a function of the spectroscopic and physicochemical (N, P, K, pH, EC, C, HLIF, C:N, CEC, HA:HA) properties of the organic amendments. Regression models accurately assigned high yields to the sawdust- and bagasse-based composts and low yields to the Napier grass- and cotton-based composts. Electrical conductivity (EC) was the main factor limiting potted-parsley productivity, an indication that efficient management of charcoal rate and compost EC levels can aid in predicting parsley yield.

“…Many poultry farms worldwide are not using any modern approaches to improve environmental performance of poultry manufacturing. Contrarily, Fehmberger et al (2020) assess the addition to poultry manure of crude glycerine derived as a labile carbon source in biodiesel production and assess the generated organic compound's consistency.…”

Purpose Poultry production supply chains produce substantial wastes that are transformable into favorable environmental outcomes and profitable products. While overwhelming evidence supports this conclusion, scant literature is available on how such transformations are doable. Using systems dynamics, this study addresses this research gap in a national (Bangladesh) context. This study aims to contribute an integrated model for poultry supply chains that incorporate reverse flows of wastes using system dynamics (SD) engineering with empirical simulations. Design/methodology/approach This study applies SD and simulations of alternative supply chains with versus without reverse loops that transform wastes into viable products in poultry production and downstream marketing operations. This research reports on an in-depth case study of systems thinking and use of the Massachusetts Institute of Technology systems dynamics software. Data for the study are longitudinal and come from written operation records and extensive, repeated, one-on-one Interview from a large poultry plant operation in Bangladesh. Findings This study finds that several current poultry waste production problems are solvable through an integrated approach that generates viable new marketable products with substantial profitable opportunities that also contributes to reductions in industrial pollution. This study confirms that forward, backward and reverse supply chains need to be under one umbrella system to achieve economic, social and environmental benefits. Research limitations/implications This study’s SD model and outputs need additional applications in poultry supply chains in multiple countries. Applying the firm-level model that this study provides is a necessary but insufficient step toward empirical confirmation through replicating.
