“…All composts were maintained in accordance with national biowaste recycling regulations [28,29]. For waste containing animal by-products (ABPRs), such as fish waste and horse manure, the temperature exceeded 70 • C for at least 1 h, as required by EU regulations (EU 142/2011) [10]. To compost biodegradable waste, including kitchen waste and sewage sludge, the temperature had to exceed 55 • C for 10 d or 65 • C for at least 3 d [12,13].…”

Reusing organic waste as fertilizer is one method to reduce the use of mineral fertilizers and minimize waste disposal in landfills. Regulations have been enacted for the processing of organic waste and for recycling end products, but the humic content of organic fertilizers has been neglected. We studied seven composts with different organic input materials and technologies. Humic substances (HSs) were detected in all composts. The total organic carbon in the HSs constituted 8.7 ± 0.1% (SD)–27.0 ± 0.2% of the compost dry matter. Spectral differences between the studied samples in FTIR spectroscopy could be observed at 1700–1000 cm−1, indicating differences in compost precursor material. The EEM peak, associated with humic acids (HAs), was high in composts containing animal by-products (e.g., fish waste, horse manure, and kitchen biowaste). Kitchen biowaste, also when processed by Hermetia illucens larvae and vermicompost, exhibited slower organic material transformation with low humic acid/fulvic acid ratios (<1.60). The results show the importance of source material origin and amendments, which influence the composting process and final products. Our study emphasizes the role of humic substances in the comprehensive evaluation of composts. To maximize the added value of composts, marketing strategies should consider determining the share of humic substances besides the content of organic matter and nutrients.

“…The concentration of nutrients is determined by input materials. The determination of total nutrient contents for fertilizing purposes is regulated, but results do not describe the proportion of nutrients that are readily available to plants [10,11]. The quality of mature compost is described as a combination of two criteria.…”

“…Similarly, in previous studies, it was shown that compost applications obtained from various organic wastes increase the total P content of the soil (Jakubus, 2016;Lanno et al, 2021;Santos et al, 2018). On the other hand, it was reported that humic and fulvic acid have effects on increasing the surface area in the soil, and this has an effect on capillary rooting and especially on the access of low mobility nutrients such as phosphorus to the plant roots (Noroozisharaf and Kaviani, 2018).…”

A large amount of plant pruning waste occurs after annual care in banana production areas. This waste material contains significant amounts of organic substances and nutrients. In this study, banana waste compost (BWC) was applied to the soil both alone and in mixture with leonardite (LT) and vinasse compost (VC). Treatments include: control (CL), banana waste compost alone (BWC-2: 2 t da-1; BWC-4: 4 t da-1; BWC-8: 8 t da-1), leonardite alone (LT: the recommended application rate), leonardite with banana waste compost (BWC-2+LT; BWC-4+LT; BWC-8+LT), vinasse compost alone (VC: the recommended application rate), vinasse compost with banana waste compost (BWC-2+VC; BWC-4+VC; BWC-8+VC). Afterwards, the changes in the activities of nitrogen (NH4+NO3) and phosphorus (available P) related enzymes (urease and alkaline phosphatase) were monitored through analyzes made on soil samples taken on certain days (0th, 10th, 20th, 40th, 80th). During this period, the pH and EC values of the soil were also measured. According to the results obtained; it was determined that banana waste compost combined with leonardite generally positively affects the pH, EC, exchangeable NH4-NO3 and, available P of the soil, as well as the activity of urease and alkaline phosphatase compared to other treatments. In this regard, according to the control, the urease activity of the soil increased by 875%, the alkaline phosphatase activity by 149%, the exchangeable NH4+NO3 by 188%, available P by 83%, and the EC value by 100%. However, the pH value decreased by about 5%. As a result, it can be stated that the application of banana waste compost combined with leonardite as a soil conditioner at least 4 t da-1 will be economical and 10 to 20 days after this application, nitrogen and phosphorus availability will increase in the soil.

Vermigot is an organic fertilizer produced from a combination of vermicompost and BSF compost. By applying Vermigot fertilizer to maize on Inceptisol, it’s hoped that it can help increase maize production and improve the chemical-biological characteristics of Inceptisol. This research aims to determine the effect of various doses of Vermigot fertilizer on the chemical and biological properties of Inceptisol soil and maize production This study used a Non Factorial Randomized Complete Block Design (RCBD), including: V0 = 0 gram, V1 = 100 gram, V2 = 200 gram and V3 = 300 gram with 6 replications to obtain 24 treatments. Parameters observed included maize production: shoot dry weight (g), root dry weight (g), corncob weight (g), final plant height of the vegetative phase (cm) and stem diameter at the end of the vegetative phase (mm). Inceptisol soil chemical-biological properties: pH soil, C-Organic (%), N-Total (%), Available-P (ppm) and microbial population (CFU/g). The maize variety used was Pioneer 35. The results showed that the application of various doses of Vermigot had a significant effect on the chemical of the Inceptisol, pH soil with the highest treatment at the V3 (300 g) of 6.80 (neutral) and the available-P of the soil with the best treatment V3 (300 g) of 31.90 ppm. Microbial population had no significant effect and maize production (Zea mays L.) had a significant effect, the weight of corn cobs with the best treatment V3 (300 g) of 250.56 gram.
