“…Research has shown that the short-term effect of applying such manures with a high carbon to nitrogen (C:N) ratio was reduced crop production, particularly where existing soil mineral N levels were low and/or the C:N ratio of the manure was high (Thomsen & Kjellerup 1997;Qian & Schoenau 2002). There are conflicting data in the literature regarding N mineralisation rates from manure-amended soil; one incubation study observed a poor correlation between C:N ratio and the rate of N mineralisation (Griffin & Hutchinson 2007), while other studies showed higher rates of N mineralisation from materials that have lower C:N ratios (Chadwick et al 2000;Qian & Schoenau 2002;Moore et al 2010). None of these studies evaluated manures with a C:N ratio above 20.…”

“…Fertilizing efficiency of compost products depends on many factors including feedstock materials and the specifics of the process used (Griffin and Hutchinson, 2007). Aerated composting encourages breakdown of organic material by aerobic micro-and macro-organisms often under thermophilic conditions (BioCycle, 2008).…”

Solid residues produced by processing food waste via Microaerobic Fermentation (MF) and by Black Soldier Fly larvae (BSFL) have been proposed as soil fertilizers. Yet, little is known about their effects on plant growth. This study compares the growth of corn plants (Zea mays) in soil amended with MF or BSFL residue, with effects of aerated compost on corn growth over ten weeks. Corn plants grown in soil amended with MF residues were 109% taller and had 14% more leaves than those grown in traditional aerated compost (Cedar Grove). But plants grown in BSFL residues were stunted, growing 39% shorter and having 19% fewer leaves on average. Only height data was statistically significant. Results indicate that MF produced from food scraps is a suitable soil amendment product, but BSFL solid residue from a similar source is phytotoxic when amended, untreated, into soil in a ratio of one part residue to two parts soil. More research on additional post-processing methods for BSFL solid residue is needed.

“…In order to ensure the compost of the best quality, some researchers suggested using a suite of physical and chemical parameters to evaluate compost maturity [3][4][5][6]. At the same time, to detect potential harmful effects on plants, several studies have used germination and plant tests as indicators of compost maturity [1,4,7]. Spent mushroom is a by-product of the mushroom industry.…”

Maturity of compost is an important practical factor in agricultural and horticulture production. This study was conducted to perform maturity assessment for spent mushroom compost (SMC). Compost maturity were evaluated using standard chemical analyses (pH, EC, CEC, total C and N content, C/N ratio, NH 4 + -N, NO 3 --N). Subsequently, potential phytotoxicity from SMC was assessed by germination bioassay using Lepidium sativum L. (cress). SMC samples were collected periodically during a 28-d rapid composting period from a single windrow. Following composting time, the pH and EC values had a tendency to increase, and in the end, the two values maintained constant. The increasing continuously CEC did not appear to be a more sensitive indicator. Although total C content (TC) and total N content (TN) were of limited value in assessing compost maturity, C/N ratio decreased significantly. NH 4 + -N declined within the first 14 days of composting, while NO 3 --N did not increase until 14+ days. According to seed germination index (GI), when composting time was prolonged, the toxicity of SMC had a tendency to decrease. Results from the experiments indicate that 21 days after rapid composting, SMC is considered to be mature. It is therefore concluded that pH, EC and GI have potential as useful indicators for SMC maturity evaluation.
