Purpose Crop wastes are underused organic resources due to low heating value and slow decomposition rates. However, conversion to biochar through pyrolysis could offer agronomic and environmental benefits. The study compared the pyrolysis of biochar from crop wastes, assessed their physicochemical properties for the purposeful use to improve soil fertility, crop productivity and their carbon […]
Purpose The purpose of this study was to assess the efficacy of inorganic additives during the humification of poultry waste and rice husk. Methods Poultry waste mixture was treated with aluminum sulfate 3% and rock phosphate 2% during co-composting of mixture in mechanical composter and evaluated the potential of humification and compost nitrogen mineralization in […]
Purpose The present research was conducted with the objective of exploring the vermicomposting process, which involves different stages such as building of a vermicompost station; import of a compost earthworm (Eisenia foetida</em>); and production of vermicompost using dry grass clippings, rice straw and cow manure. The vermicompost produced can be of significant value to the end […]
Purpose Nigeria produces large quantities of wastes per year, which are underutilised and constitute environmental nuisance. The effect of dietary mycomeat produced from ogi production wastes based on yellow maize using wild and mutant strains of Pleurotus sajor-caju was assessed based on chickens’ growth, haematology and histology. Methods The wastes were air-dried for 72 h. […]
Purpose A lots of poultry litter (PL) is being generated every day from poultry industries and improper management leads to different environmental problems. Production of biochar from PL is a new management strategy of PL which is a nutrient-rich organic amendment for improving soil nutritional status. The experiment was aimed for the production of poultry […]
Purpose Four different types of composts were assessed in two methods of application for their potential to support organic tomato yield. Methods A 2-year experiment was conducted using four different soil conditioners: cow manure (CM), household compost (HC), spent mushroom compost (SMC), and vermicompost (VC). Three different application rates (10, 20, and 30 t ha−1 for all […]
Purpose Riparian zones are identified as mitigation areas of agricultural pollutants to river ecosystems. However, the mitigation mechanisms of these pollutants remain unclear mainly on the effects of different types of riparian vegetation and its organic matter content in the pollutants removal process. This study aims to assess the content of organic matter in soils […]
Purpose Intensive agriculture activities in small holder farming systems are declining over all soil nutrient status. The present study is conducted to compare the soil health and plant growth attributes under rice cultivation among different organic amendments. Recycled waste of rice–wheat agrosystem is utilized to determine optimal sustainable solution for hilly areas. Methods Randomly blocked […]
Purpose This study assessed changes in bio-quality indices and plant available P released during aerobic–thermophilic cocomposting of different mix ratios of non-reactive ground phosphate rock (GPR) with poultry and cattle manures. Methods Aerobic–thermophilic co-composting of different mix ratios (5:5, 8:2, 7:3 and 9:1) of non-reactive GPR with poultry and cattle manures was carried out. Compost […]
Purposes The purpose of this research was to evaluate the kinetics of anaerobic microbial culture during adaptation to pure and complex lignocellulosic substrates at low temperature. Methods Six pairs of 1.0 L batch reactors maintained at 20 °C were fed pure (xylan and cellulose) and complex (cow manure and wheat straw) lignocellulosic substrate in three successive […]
