Purpose The region of Souss-Massa generates huge quantities of organic horticultural wastes estimated up to 1,307,465 tonsyear-1 . Fruit and vegetable producers are asked to process the organic wastes because of the GlobalGAP certification requirements. As a result, there is a need to assess the existing composting plants at regional scale, to improve their efficiency, […]
Purpose In this study, the composting and co-composting potential of coffee husk and pulp with source-separated municipal solid waste (SSMSW) was investigated. Methods Coffee husk and pulp were mixed independently with SSMSW in different proportions (0, 33, 50 and 100%), and composted in triplicates with a total of 24 composting piles for 3 months. From each […]
Purpose The work aimed to investigate the effect of cow dung and cellulolytic bacteria on humic characteristics during municipal solid waste composting. Four Bacillus isolates (B. subtilis, B. tequilensis, B. venezuelans and B. amyloliquefaciens) sourced from dumpsite soil were formulated as consortium for the study. Methods Four treatments were considered with addition of bulking agents (ratio 1:7:6) to 15 kg […]
Purpose Manure extracts possess great potential as alternate inorganic fertilizers. However, limited information exists on how manure influences plant growth. This study’s aim was to determine the impact of aerated manure extracts on romaine lettuce (Lactuca sativa var. longifolia) and Russian kale (Brassica napus var. ‘Red Russian’) in hydroponic systems. Methods Chicken, cow, and turkey […]
Purpose A pilot composting project was initiated as part of a 200 tons/day solid waste recycling plant with active involvement of several local stakeholders. The project aimed at introducing compost production and use in the village of Al Jalameh, Palestine. This paper describes the successes and lessons from the pilot project. Methods Based on the […]
Purpose Bacterial and fungal communities represent key bioindicators of soil quality and are essential for the maintenance of nutrient availability. Our purpose was to characterize the bacterial and fungal biodiversity associated with different compost mixtures, comparing microbiological indicators regarding the soil quality. Methods Compost samples and mixtures were prepared (15:1 final ratio) with chemical fertilizer, […]
Purpose Shortage, high prices and adverse effects of fertilizers drive to hunt alternative sources (such as compost) for crop husbandry and environment sustainability. A field trial was executed to observe the effect of various composts on growth and macronutrients’ concentration in fodder maize (Zea mays L. cv. Akbar). Method The treatments with four repeats included: […]
Purpose A study was carried out on composting pistachio hull aided with chemical fertilizer. Recycling of pistachio wastes is one of the major agricultural way in pistachio producing country. Method The collected pistachio hull was allowed to decompose either naturally through composting or with the addition of chemical fertilizers. Biological and chemical properties with organic […]
Purpose Poultry litter (PL) and basalt rock powder (BRP) are raw materials highly produced in some Brazilian regions. The association of these products can generate greater added value for the agribusiness chain and be a sustainable source of fertilizer. Method The experiment consisted of an incubation trial over time for chemical characterization of the materials. […]
Purpose Phosphorus (P) is one of the key elements in the agricultural sector, allowing improved production yields. Phosphate rock is a natural source of phosphorus; however, its low reactivity limits the release of P available to plants in the short term, conditioning its application in a direct way. Research was conducted to determine the effect […]
