Abstract
Globally, the poultry industry generates approximately 3.29 million metric tons of poultry waste annually, of which 2.36 million metric tons are produced by laying hens. This poultry waste has the potential to be utilized as an organic fertilizer in the field. This study aimed to investigate the possibility of using poultry manure to improve soil quality and its effects on plant growth. Both aerobic and anaerobic composts were prepared for 40 days using the windrow and bin methods, respectively. The effects of organic compost application in three treatments (25%, 50%, and 75%) on three different species of plants (marigold, spinach, and parsley) were determined over a period of 90 days. The physicochemical and microbial characteristics of the compost were determined prior to its application to the plants. The periodic monitoring of plant growth showed significant impacts of aerobic and anaerobic poultry compost compared to the control plants. The micronutrient concentrations in the plants were also enhanced compared to the control. Moreover, the translocation factor of heavy metals in plants followed the order Nickel (Ni)> Copper (Cu)> Zinc (Zn). The present study concludes that poultry compost with high micronutrient contents can be utilized effectively as an organic fertilizer, which can not only lower the quantity of poultry waste but also provide economic benefits
