Modification of Anaerobic Composting Process Using Natural Clinoptilolite Zeolite on the Quality of Physical and Chemical Properties
The research investigates the impact of clinoptilolite zeolite on the physical and chemical properties of biofertilizer produced through anaerobic composting. The study, conducted in Sabzevar, Iran, aimed to enhance the quality of compost derived from cow manure by incorporating varying percentages of natural clinoptilolite zeolite. The research involved preparing 90 samples with different zeolite concentrations (0%, 5%, 10%, 15%, and 20%) and analyzing them over a 60-day period.
Key parameters measured included pH, electrical conductivity, temperature, carbon-to-nitrogen ratio, and nitrate levels. The findings revealed that the addition of zeolite led to significant changes in the composting process. Specifically, the pH levels increased from 9.7 to 57.8, and the temperature remained stable in treatments with higher zeolite percentages. Notably, nitrate levels increased by 15%, indicating improved nutrient availability.
The study concluded that incorporating zeolite not only accelerated the composting process but also enhanced the physicochemical properties of the resulting fertilizer. This modification resulted in a more efficient composting process, reducing the time required for fertilizer production and improving its overall quality.
This research is significant in the field of environmental health and sustainable agriculture as it addresses the pressing need for effective waste management solutions. By exploring the use of clinoptilolite zeolite in composting, the research contributes to ongoing discussions about organic waste recycling and the enhancement of biofertilizer quality. The findings offer practical insights for agricultural practices, particularly in improving soil health and nutrient management.
The study's implications extend to environmental sustainability, as it highlights a method to reduce greenhouse gas emissions and improve soil conditions through organic waste recycling. Readers, including researchers, agricultural professionals, and policymakers, can benefit from the insights provided, which may inform future practices and innovations in organic farming and waste management.
