Purpose The decreasing number of peatlands has driven the search for new cultivation substrates. The aim of this study was to evaluate the use of different composts as growing media in the production of vegetable seedlings (pepper and tomato). Method Composts were produced from: discarded carrots (ZC), fats (FC), and biosolids (BC) from the dairy […]
Purpose Nematode diseases are major constraints in tomato production. Screenhouse and field experiments were conducted to assess the efficacy of Effective Microorganisms-Fermented Plant Extract (EM-FPE) and compost manure singly and in combination on Meloidogyne incognita infecting tomatoes. Method Screenhouse and field experiments were designed respectively as 2×5 and 2×4 factorial fitted into a completely randomized […]
Purpose Fertigation plays an important role in the so-called circular economy since it relies on the reuse of water and nutrients; therefore, this method is fundamental for production in areas with scarce resources. This study aimed to evaluate the effects of fertigation of soil plots with sewage on soil attributes, germination of seeds, and growth […]
Purpose Chicken eggshell (ES) is a global biowaste product of poultry industry and an enriched source of calcium required for plant growth. Therefore, the present study has been carried out to assess the potentiality of the combination of ES with vermicompost (VC) and chicken feather protein hydrolysate (CFPH) on growth and yield improvement of Capsicum […]
Purpose Chicken eggshell as a byproduct of the egg product industry makes serious problems to the environment. The aim of this study was to evaluate the effect of eggshell as a potential option in supplementing of the organic matter and improvement of soil conditions in the pot culture and the area. Method Two pot experiments […]
Purpose This study aimed to produce a value-added product by co-composting sawdust with food waste using a small-scale composter. Method The composting experiment was carried out using 60L composting bins with a hole of 3 mm and 10 cm apart drilled on its side. Three experimental trials 1, 2 and 3 were adopted in this […]
Purpose Due to the urgent need for sustainable agro-industrial waste management, a field experiment was conducted to evaluate the application of biosolids as organic fertilizer in a corn cultivation crop. In addition, to achieve food security, the study aimed to assess metals concentrations in soil and maize plants and enrichment factors (EF) for soils and […]
Purpose The study assessed the quality of compost produced by the Black Soldier Fly Larvae (BSFL) in terms of the compost nutrient level, microbial activities, and the bioaccumulation of possible heavy metals in the organic solid waste. Method The study used the pre-experimental study design, one-group pretest-posttest to obtain the data. Five experimental units were […]
Purpose This field study evaluated the interactive effects of biochar (BC) and sewage sludge (SS) on P bioavailability and spinach yields for two seasons. Method Treatments were combinations of biochar (0, 2.5 and 5 Mg ha-1) and sewage sludge (0, 6 and 12 Mg ha-1), or mineral fertilizer (200, 28, and 18.9 kg ha-1), amended […]
Purpose The aim of this work was to study the effect of adding sugar beet molasses on the biochemical properties, microbial flora, fermentation quality, and aerobic stability of prickly pear cactus (Opuntia ficus-indica) waste silage. Method Molasses (0%, 2%, 4%, 6%, 8% and 10%, w/w) was mixed with the cactus fruit scraps, straw and wheat […]
Purpose Agricultural crop residues (ACR) and agro-industrial waste (AIW) are abundant in Indonesia and primarily used as substitutes for cattle feed or to be naturally decomposed in the nearby environment. This review attempts to examine the potential valorisation of ACR and AIW into biosorbent. This paper also provides the challenges and opportunities in applying wastewater […]
