“…These findings were corroborated by Egbuna et al (2016). Electrical conductivity of the final compost was below the salinity limit value of 3 ms/cm for compost to be used as organic fertilizer (Soumare et al 2003). Available and total phosphorous, nitrogen, sulfur, as well as carbon make the compost good for use as a mineral fertilizer (Soumare et al 2003).…”

“…Electrical conductivity of the final compost was below the salinity limit value of 3 ms/cm for compost to be used as organic fertilizer (Soumare et al 2003). Available and total phosphorous, nitrogen, sulfur, as well as carbon make the compost good for use as a mineral fertilizer (Soumare et al 2003). Compost application will, therefore, lead to an increase in the levels of stable organic nitrogen and humic carbon and this will invariably improve mineral elements necessary for plant growth.…”

Purpose Sewage sludge samples from a water treatment plant in Nigeria were subjected to an in-vessel composting (using sawdust as a bulking agent) and thermal sludge processing to improve its quality for agricultural applications. Methods Treated samples were analyzed for physicochemical and microbiological properties using standard analytical and aerobic culture protocols. Results Microbiological analysis of the initial fresh mixture (sewage sludge/sawdust) showed that the total heterotrophic bacteria was 1.17 9 10 6 CFU/g of fresh compost, coliforms 4.7 9 10 4 CFU/g, Salmonella sp., and Shigella sp. 7.3 9 10 4 CFU/g, yeasts and moulds 9.0 9 10 4 CFU/g. These values were significantly (p = 0.05) reduced after 40 days of in-vessel composting to 4.3 9 10 4 CFU/g for total heterotrophic bacteria, 7.4 9 10 2 CFU/g for coliforms, while yeasts and moulds, Salmonella and Shigella sp. were not detected in the final compost. The results of the physicochemistry revealed variation in pH, temperature, and nutrients status of treated sludge. Conclusion Salmonella sp., Staphylococcus aureus, and Shigella sp. were eliminated, while a 2-log reduction in coliform counts occurred after 40 days of composting. Composting had a better processing impact by increasing the ash as well as reducing the carbon/nitrogen ratio of treated sludge, while thermal processing improved the sulfate and phosphate components of treated sludge. The treated sludge (biosolids) met the permissible limits of microbiological and nutritional standards recommended by US EPA for land application of sludge and could, therefore, be used as a biofertilizer, soil conditioner and also for land reclamation.

“…Onion is a heavy feeder, requiring ample supplies of nutrients. The use of organic manure and compost has been shown to improve the soil organic matter content and crop yield (Soumare et al, 2003). The mineral composition of crops depends on the amount and type of nutrients taken from the growth medium, and it is necessary that adequate amount of nutrients should be available for the production and nutrient content of crops (Barker et al, 2006).…”

Plant spacing determines to a greater extent crop performance in terms of growth and yield. The production of crop with organic fertilizer also plays a vital role in organic agriculture. Field studies were conducted to evaluate the effects of spacing and poultry manure on the growth, yield and quality of onion. Three spacing regimes were carried out consisting of 15 cm × 15 cm, 20 cm × 20 cm and 25 cm × 25 cm and four levels of poultry manure at 0, 5, 10 and 15 t /ha. The effects of spacing and poultry manure were evaluated for two years based on plant growth, yield, nutrient concentration, uptake and proximate composition of onion plant. Leaf thickness, bulb and shoot fresh weights were significantly increased by the wider spacing of 20 cm × 20 cm and 25 cm × 25 cm, compared with the narrower spacing of 15 cm × 15 cm in both seasons. However, the highest total dry yield (1.82 and 1.58) t/ha, shoot yield (2.31 and 1.32) t/ha and total fresh yield (13.69 and 12.55) t/ha were obtained with the spacing of 20 cm × 20 cm in both years. Similarly, application of poultry manure increased leaf thickness, bulb and shoot fresh weights and yields compared with the control. Generally, using 10 t/ha poultry manure has a superior effect on proximate composition and most of growth parameters and yield components achieved the highest nutrient concentrations and uptake on most of the macro and micronutrients in leaves and bulbs as compared with the control in both years.

-The application of the organic fertilizers in soils is essential to maintain soil fertility and increase crop productivity. Organic fertilizers improve the physical, chemical and biological characteristics of soils. Different compost derived from the composting of the waste fermentable, are used in this experiment. The composts have different particle sizes (10 mm and 40 mm). The latter has basic pH values (8-9), C/N ratios varying between 17, 7 and 19, 7. The organic matter rate, answer to norm NFU 44 051 (varying between 34% and 48%). The analyses of the elements trace metallic show that the rates are in conformity with the international standards of organic amendments. The results of phytotoxicity show that the composts are mature. The different compost (fine and coarse) added to mineral fertilizers gives of the rates high of potatoes (50 %, 50, 8 %) and turnips (59, 5%, 62 %), whose the caliber is over 55 mm. This shows that compost is a necessary additive to minerals fertilizers since it acts as an organic amendment for the fertility of arable soils, and it acts as a mineral amendment for a better productivity of the different cultures.
