“…In the Mediterranean region, the overuse of chemical fertiliser application to increase crop productivity caused several soil problems, such as structure deterioration, organic matter reduction, fertility declination, physicochemical plus microbial changes, erosion, and groundwater pollution (Liang et al 2013;Montemurro et al 2010;Meena et al 2016). For this reason, organic fertilisers have been suggested by many researchers as an efficient alternative (Pradeepkumar et al 2017;Cervera-Mata et al 2018). Organic fertilisers are commonly applied instead of mineral fertilisers to enhancing the sustainable agricultural ecosystems without affecting the yield and quality (Hernández et al 2016;Abuarab et al 2019).…”

The 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. The effect of either mineral or organic fertiliser on soil fertility or the microbial community was also studied. Control plots were fertilised with recommended rates of mineral fertiliser (150: 45: 65 kg/ha NPK) and the other treatments were 15 t/ha compost, 10 t/ha rabbit manure, and 10 t/ha chicken manure. Our results indicated that all sources of organic fertiliser significantly increased total nitrogen, organic carbon, total fungi, and bacteria contents of soils compared with mineral fertiliser. Rabbit and chicken manure fertilisers resulted in a significant increase in yield. Compared with conventional fertiliser and other organic treatments, plots receiving rabbit manure showed a lower weight loss and microbial load on fresh lettuce head. Moreover, rabbit manure significantly reduced polyphenol oxidase and peroxidase activity. Hence, these results suggest that rabbit manure fertiliser could be an alternative to conventional production without significant reduction in yield and with low enzymatic browning and better storability.

BACKGROUND: Spent coffee grounds are the most valuable resource for agriculture and industry. However, it is almost thrown untreated into landfills or incineration. Composting is an efficient process for converting spent coffee to fertilizer. METHODS AND RESULTS: Composting was conducted in the compost pile (40 m 3) equipped with a forced aeration system. Physical and chemical properties containing temperature, pH, electrical conductivity, and moisture were measured through the composting period. Moreover, biological changes were examined for the composting phase using Illumina Miseq sequencing of the 16S rRNA gene. We found 7-14 phyla comprising 250-716 species from a variety phase of compost. During the composting period, Firmicutes were dominated, followed by Actinobacteria and Proteobacteria. CONCLUSION: The result indicated that the use of spent coffee improved the quality of organic fertilizer and changed the microbial communities, unique to the thermal composting stage, which could enhance the composting process. These findings suggest that spent coffee composted material can provide a significant amount of nutrients, thereby supporting plant growth.

“…Due to its composition and structural characteristics, SCG are used as animal feed, activated carbon, carbonaceous materials, absorbents, etc., (Murthy and Naidu, 2012). SCG have also been employed as organic amendments for soils, both in their fresh form (Cruz et al, 2012(Cruz et al, , 2014a(Cruz et al, ,b, 2015Yamane et al, 2014;Hardgrove and Livesley, 2016;Cervera-Mata et al, 2018), and when composted (Cruz et al, 2014a,b).…”

We investigated the short-term effects of spent coffee grounds on the physical properties of two Mediterranean agricultural soils (Calcisol and Luvisol). The in vitro assay was performed with two spent coffee grounds doses (60 and 240 Mg ha-1), two incubation times (30 and 60 days) and two modalities: with and without lettuce seedlings (Lactuca sativa var. longifolia). Spent coffee grounds addition increased water retention at-33 and-1500 kPa, and decreased bulk density and plant-available water content. With spent coffee grounds, the percentage of macroaggregates increased, the percentage of meso-and microaggregates decreased and the structural stability of all types of aggregates increased. The stereomicroscopy images showed that: the structural aggregates were rounded, the porosity increased by 316%, the structure was ordered into smaller aggregates, the incorporation of spent coffee grounds particles could occur in intraped cracks and spent coffee grounds particles could act as a binding agent. Scanning electron microscopy also showed that spent coffee grounds particles interacted with mineral particles and integrated into soil structure; moreover, fungal hyphae also developed on many spent coffee grounds particles. If spent coffee grounds effects are compared with those described in the literature for other organic amendments, the same trend was observed in most of the soil physical properties although with a different intensity, principally with regard to structural stability.
