Abstract

Utilizing broiler manure for composting at the same time addressing environmental issues can be a feasible alternative for broiler raisers. The study aimed to determine the effects of adding a rapid odor erasing and composting microbes (OECM) at different inclusion rates of 350 grams per 100 kg raw material (50 kg broiler manure + 50 kg fly ash), T2 400 grams per 100 kg raw material (50 kg broiler manure + 50 kg fly ash), T3 and 450 grams per 100 kg or raw material (50 kg broiler manure + 50 kg fly ash), T4 on physical properties, temperature, pH, germination rate, and percentage compost recovery. The control T1 was 100 kg raw material with no OECM. A Completely Random Design (CRD) was used consisting of 4 treatments with each treatment replicated thrice. Tukey HSD was used to further analyze significant differences. Result showed that the odor of treated compost was no longer evident on day 13 for T2, T3, and T4. The texture from coarse to fine was observed in day 13 of T2, T3, and T4, while the color from black to grayish black was demonstrated on day 13 of T2, T3, and T4.

The temperature (p. < 0.01), pH (p. < 0.01), compost recovery (p. < 0.01), and germination rate (p. < 0.01) were significantly different over the control. Therefore, the OECM at 350 grams, 400 grams, and 450 grams per 100 kg raw material is an indispensable additive for broiler-based manure as it significantly improved the varying compost quality parameters.

Introduction

According to Bolan et al. (2010), one of the biggest and quickest expanding agricultural sectors in the Philippines and in other country was the poultry industry. Due to its acceptability by most societal segments and its comparatively low cholesterol level, chicken meat was in higher demand. Globally, poultries are one of the Philippines' most significant agricultural subsectors. Among all the animals reared for commercial use, chickens accounted for most of the poultry production in the country. To date, the Philippines' Central Luzon region has the greatest number of backyard and commercial farms. However, several environmental issues are now facing the chicken sector. This was attributed to the buildup of numerous wastes, particularly manure and litter. If management techniques that are both ecologically and economically viable are not used, the accumulation of these wastes may cause environmental degradation.

Improper waste management has a detrimental effect on the ecology (Maheshwari, 2013). Near chicken farms, land degradation, and nuisances including stink, insects, and rodents are common neighborhood drawbacks. Poor manure management frequently results in the contamination of water and soil containing pathogens, heavy metals, and nutrients in areas where manure was stored. Poultry services emit unpleasant smells and draw rodents, flies, and other pests that spread disease and annoy the neighborhood. Numerous substances, such as ammonia (NH3), volatile organic compounds (VOCs), and hydrogen sulfide (H2S), can contribute to odor emissions. Consequently, the lives of those who live close to poultry houses are impacted by poultry farms. (Maheshwari, 2013).

Broiler manure was the excess of chicken from poultry industry that can be recycled as nutrient source as it contains the macro nutrients namely: nitrogen, phosphate, and potassium, which can be applied to crops and pasturelands. In Nueva Ecija chicken manure was proven to be efficient as source of organic fertilizer among farmers for their crops (Villegas, 2017). Moreover, organic fertilizer was a type of fertilizer in which all the components are organic. Because of its composition, it was also safer than synthetic fertilizers. Organic fertilizer can make your plant vibrant, larger, and more nutritious. An organic fertilizer composition includes the manure of chicken, hog, goat, and quail manure, dried leaves, mulching, and other bulking agents. Organic fertilizer was also less expensive than chemical fertilizers, which was why most farmers apply it for their crops and minimizing the use of chemical-based farming.

According to Wardynski (2015), for livestock and poultry farmers, composting has become a more popular strategy for managing animal waste in recent years. Animal dung has been applied as a soil supplement to enhance soil health for avery long time. Application of animal manure compost has several advantages namely: enhanced storage possibilities, reduction in the amount of material that must be carried and distributed on fields, and abetter match for hay and pastures throughout the growth period than raw waste.

The researcher was interested in this investigation since organic fertilizer is more chemical-free, inexpensive, and prevent the adverse effects of occupational hazards to farmers. Recently, there was now a growing awareness on the consumption of chemically tainted unhealthy food to our health. The shift to the use of organic fertilizer should be encouraged and maximized. Novel strategies then on how to process animal wastes particularly broiler manure efficiently and rapidly should be explored as it was demand would be expected soon. 1.1 Significance of the Study: Considering the increasing acidity of the soil in recent years, the need to popularize the use of organic fertilizer must be explored to address environmental degradation and mitigate the adverse effect of climate change. Moreover, biomass by-products such as fly ash, which is abundant in Nueva Ecija, should be utilized for maximum productive use, particularly as a bulking agent to produce organic fertilizer. Moreover, out of 65.22M broiler in the Philippines with an average of monthly intake of 195,660,000 million this will produced 48,915,00 kilogram of manure monthly. If this will be now converted for organic production and equal amount of bulking agent will be added there will be a total of 97,830,000 of compost that will be produced. If percentage weight loss in broiler manure-based composting 0.35%, therefore a total of 34,240,500 of organic fertilizer monthly is expected or 684,810 bags of organic fertilizers at 50kg per bag can be produced. This is a potential source of macronutrients supply (NPK) for paddy field rice in the Philippines. 1.2 Scope and Limitation of the Study: The annual based manure is limited to broiler manure only. The different Odor Erasing Microbial Compost additives were 350, 400, and 450 grams per 100 kg raw materials composed of 50 kg broiler manure and 50 kg fly ash. Moreover, different of varying parameters was done from day 1 to 14 days only. The physical parameters of the compost were limited to texture, color, and odor. While the compost quality was measure by compost recover and the germination rate of pechay seeds.

Conclusion

The study has shown that T2 was most effective in reducing the weight of the compost Likewise, it produced the highest percentage on the germination of pechay which 87.333 % among other treatments tested got the lowest rate of germination like in the t1 (control) had a total of 36.67 % only. For economic reason, composting alone may also be a good alternative treatment for vermicompost production. Moreover, the study confirmed on day 14 that all the inclusion levels of the OECM to the broiler manure did not influence increased in temperature. The study confirmed that all the inclusion levels of the OECM to the broiler manure did not influence significant change in pH. The study concluded that the inclusion level of OECM at 350 grams (p- <0.01) significantly increased the % weight loss at 39.67% over the control which is only 28.67% VII. RECOMMENDATION The study recommends a higher inclusion level to significantly increased the temperature in future studies because the ideal composting temperature requirements is around 60-65°C for thermophilic microbes. The study recommends a higher inclusion level to significantly increased the pH because is essential to the plants. The study recommends an inclusion level of 350 grams OECM to significantly increase germination index. The study recommends an inclusion level of 350 grams of OECM to significantly increase compost weight loss.

Considering the economics of the utilization of the OECM, a lower inclusion rate canthus be recommended to lower the production cost of the compost. Furthermore, the researcher recommends including the following parameters for future studies: present of heavy metals, porosity, NPK, and C:N ratio.
