“…TKN concentrations of all treatments decreased greatly at the start of the composting process and then increased by the end of the process (Figure 2a). As previously reported by Awasthi et al [41], the initial decrease in TKN is attributed to ammonia (NH 3 ) emissions, and the subsequent increase in TKN probably resulted from the decomposition of organic matter. Among the nine treatments, TKN increases were the earliest and greatest in treatment T9 (55% CM and 15% BM), while the TKN decreases were greatest in treatment T6 (35% CM and 15% BM).…”

In China, chestnut burrs (CB) are produced at a rate of a million tons per year as the major byproduct of chestnut orchards. It is necessary to utilize the chestnut forest green waste and convert it into a valuable seedling media for the sustainable cultivation of chestnut seedlings. In this study, we composted CB with two waste products of cattle farming, namely cow manure (CM) and bovine bone (BM). We also evaluated the potential of CB compost application in chestnut forest sustainability. Results indicated that the best combination was the addition of 15% BM and 55% CM. This combination significantly improved the composting environment by increasing pH, enhancing phosphorus concentration and mineral elements such as Ca, Na, Mg and Zn, and shortened the composting period to 38 days. This combination also resulted in the highest content of citric acid-P (109.20 times than the control treatment) and the lowest content of NH 4 + -N (0.28 times than control treatment) indicating a better N and P structure of the final compost product. This combination achieved a greater degradation rate of CB cellulose (61.45%), hemicellulose (37.87%), and a more significant degradation of outer epidermis structure. When CB compost was used as a growing media, a significant decrease in photosynthesis stress of chestnut seedlings was observed, which was mainly manifested as a decrease in photochemical quenching (qP) and an increase of the maximum efficiency of PSII photochemistry under dark-adaption (Fv/Fm). Addition of 10% CB compost (in volume basis) is suggested, which resulted in the tallest chestnut seedlings (59.83 cm) with a stem diameter of 0.91 cm after six months of growth. In summary, this research provides an environmentally friendly strategy for chestnut orchard sustainability: rapid composting of CB, then immediate application as a high-quality substrate for chestnut seedlings.Agronomy 2020, 10, 288 2 of 18 step for chestnut production. The popularization of burr removal equipment has resulted in the need for intensive management of CB. Due to CB recalcitrant biodegradability and knotty spicular structure, incineration is still the main method of dealing with CB waste [3,4]. Since CB, as FGW, is rich in organic matter and minerals, it is desirable to convert it into a high value byproduct such as compost.Composting is a popular and clean method to dispose of FGW [5]. Mature FGW compost has high porosity and high organic carbon content and can be utilized as a high-quality soil amendment [6]. Shrestha et al. [7] reported that the application of compost increased soil organic carbon content, reduced CO 2 and N 2 O emissions, and increased CH 4 uptake. Chehab et al. [8] indicated that the olive FGW compost amendment resulted in an increased performance in mature olive trees and in a maximum yield of photosystem II (Fv/Fm). Composting recycles organic matter, nitrogen, phosphorous, and mineral elements in the FGW when growing seedlings [9]. In a recent study, Shalizi et al. [10] increased the biomass of Eucalyptus bentham...

“…The correlation coefficient between temperature and pH, content of soluble P 2 O 5 and available P 2 O 5 , was r = −0.649 ( P < 0.05), r = 0.757 ( P < 0.05) and r = 0.771 ( P < 0.05), respectively. However, it would be interesting to perform the experiment in a real composting process where thermophile temperatures are reached; it is worth seeing whether B. megaterium would survive the high temperatures and would be able to colonize the solids once back to the mesophilic range, or should the inoculation be performed after the thermophilic phase instead, since a thermophilic phase is always required in composting to inactivate weed seeds and pathogens in the compost . The presented results are a preliminary stage for future experiments that will be performed at proper scale to discuss the effect of scaling up the process.…”

BACKGROUND This paper details the results of solubilization of phosphates in spent mushroom substrate (SMS). As a substrate for the process, bones as a source of phosphates and SMS as medium were used. RESULTS The process was conducted for 9 months and at the end of the process the substrate obtained was characterized as having a two times higher amount of available phosphorus (express as P2O5), which was confirmed by FTIR and SEM‐EDX analysis. A decrease in pH was observed. Strong correlation was found between temperature and the effectiveness of the process (P=0.000, r = 0.772). Solubilization combined with the degradation process lowered the C/N ratio from 13.6:1 to 11.7:1. The utilitarian properties of the substrate obtained were evaluated in germination tests. CONCLUSION The substrate obtained was characterized as having two times more available phosphorus and can serve as a biofertilizer for the cultivation of plants. © 2016 Society of Chemical Industry

“…The concentration of NH 4 + -N showed a downward trend from day 0-46 during composting, then reached stable for TM and CK (Fig. 2a), which may be due to the utilization by ammonia oxidizer or converted into NH 3 under high pH and temperature (Awasthi et al, 2016). The similar result was also found during the composting of pig manure with sawdust (Huang et al, 2004), although the common increase of NH 4 + -N content in the initial stage of composting was reported (Wang et al, 2015).…”
