“…Referring to the set of experiments held [ [21] , [22] , [23] , [24] , [25] , 27 , 33 , 34 ], the carbon/nitrogen ratio ranged between 9 and 19 for the different produced composts, in agreement with the standard recommended value. The difference noticed is related to the raw materials variety used, and characterized by different physico-chemical parameters.…”

“…The objectives of the present study and that of Echarrafi et al [ 9 ] were to setup an optimized model where the OMW is recycled at the highest rate. Consequently, we can deduce that the use of 3 output variables (pH, OM content, and C/N ratio) instead of 2 (OM content and C/N ratio), and the data exploitation already validated by research laboratories [ [21] , [22] , [23] , [24] , [33] , [34] , [35] ], give an improved and satisfactory result. Indeed, Table 5 summurized the determined initial composting materials composition rates according to both of the studies.…”

“…Diverse studies had developed composting of organic waste, such as OMW [19,24,[27][28][29][30], sludge from wastewater treatment [31], and agro-industrial waste [32]. While other studies on the co-composting of olive mill wastewater with poultry manure [25,27,33], olive mill wastewater with solid organic waste [20,34], and date palm with activated sludge [35] have been carried out.…”

In order to decrease the environmental harm produced by the agro industries’ wastes’, an investigation of the co-composting of olive mill waste (olive mill wastewater (OMW), olive mill sludge (OMS)) and wine by-products (grape marc and winery wastewater) was done. Three aerated windrows of variable compositions were performed; these windrows differ in terms of their initial composition and the liquid used for their humidification; OMW and wastewater winery were used for humidification to replace water for windrow moistening. Moreover, the main physicochemical parameters (temperature, pH, electrical conductivity, and C/N) were monitored to evaluate the co-composting process. The latter lasted around three months. The elaborated composts were characterized by low C/N ratio, and they were rich in fertilizing and nutriment elements and of low heavy metal contents. The humidification of the windrows with OMW showed effectiveness in improving the windrows temperature, reflected by the high temperatures monitored during the composting process in comparison with the windrow humidified with winery wastewater. Furthermore, a longer thermophilic phase was held in windrows carrying OMS. The valorization of the produced composts for soil amendment significantly improved the soil fertility. Indeed, field experiments showed an increase in radish yield by 10%, the composts were harmless and did not have any phytotoxic effect on radish growth.

“…Currently, various research studies have shown that composting is one of the most effective methods for the recycling and recovery of organic waste [2,4,[16][17][18][19]. It is a biodegradation process of the organic matter, allowing the obtaining of a stable product, rich in humic substances and in fertilizing elements, serving as a soil organic amendment [2,20].…”

Farmers’ Perceptions and Willingness of Compost Production and Use to Contribute to Environmental Sustainability

et al. 2021

Composting is an ecological method of recycling organic waste. It presents an effective solution to reduce the large volume of agricultural waste and provides an organic fertilizer and soil amendment. However, its implementation remains limited, especially in Morocco. The vast majority of farmers are unaware of the effectiveness of compost, and it is often considered as an inefficient product compared with chemical fertilizers. In order to develop a local marketing strategy for compost, this study aims to identify the perceptions and willingness of farmers to produce and use compost in agriculture, and to assess the factors shaping these perceptions and willingness, including socio-economic, agricultural and individual factors. The case of Morocco is investigated, where the vast majority of farmers practice inappropriate disposal of agricultural waste and excessive use of agro-chemicals. Data are collected using a standard questionnaire and face-to-face interviews with 350 farmers during their visit to the international agricultural exhibition in Morocco. Descriptive statistics and analysis of variance (ANOVA) are used for data analysis. The results showed a high level (80%) of acceptance by farmers of the production and use of compost. Farmers are also very willing to produce and use compost in agriculture. All the socio-economic, individual and agricultural factors, except gender, length of experience and cultivated area, had a highly significant influence on farmers’ perception and willingness to produce compost (p < 0.005). The positive perceptions of farmers and the high level of willingness to produce compost imply that the composting of organic waste should be encouraged by our local authorities. The production of compost will thus contribute to environmental sustainability and to the promotion of the ecological management of agricultural waste meeting the requirements of a circular economy.
