Investigating the mineral and chemical properties of horse riding and breeding complexes in order to reduce environmental pollution

The horse breeding and keeping industry has created employment in many provinces of the country. The purpose of this research is to investigate the potential of using organic waste from riding and horse breeding complexes. The waste of equestrian and horse breeding complexes is mainly organic and includes manure and bedding. This research was done in the spring and summer of 2023. To obtain information, an online questionnaire was provided to people who were somehow related to riding and horse breeding centers. The results of the questionnaire were analyzed and analyzed by SPSS software and statistical tests. The waste of one of the equestrian clubs was performed and physical, chemical and biological tests were performed. The physical analysis of the fertilizer of the physical waste (fertilizer and substrate) shows the values of ash 23.6%, 66% moisture and 34% dry matter. The measurement of the C/N ratio showed that horse fertilizer has high values of C/N. The amount of phosphorus 192 ppm, nitrogen 5.63%, organic carbon 44.3%, C/N ratio 7.8, ammonia 125.2 ppm, organic matter 76.4%, zinc 62.50 ppm, iron 65 ppm and copper 11.80 ppm have been seen in horse litter. Ash 23.6%, moisture 66% and dry matter (solid) 34% were measured. horse fertilizer is not dangerous to humans in terms of coliforms and pathogens. The calorific value of horse manure showed that this waste can also be used as fuel.
