Agriculture wastes conversion for biofertilizer production using beneficial microorganisms for sustainable agriculture applications

ABSTRACT

Aims: The emphasis of this study is to generate new valuable bioproducts from non-toxic cleaning waste for environmental healing technology. Methodology and Results: Comparisons between different types of biofertilizer formulations and the field trial effectiveness were done. Results indicated that biofertilizer C contained the highest N value (1.8%) when compared with biofertilizers B and A, which only contained 1.7% and 1.4%, respectively. Biofertilizer A showed significant difference in the total count of yeast, mould, ammonia oxidizing bacteria and nitrate oxidizing bacteria compared to biofertilizer B and C. Meanwhile, biofertilizer C was found to be significantly different from others in Lactobacillus sp. and nitrogen-fixing bacteria count. Photosynthetic total count and Actinomycetes sp. were not noticed in all formulations tested. Conclusion, significance and impact of study The findings of this study suggest that biofertilizer A is suitable to be used as a promotional biofertilizer in flower and fruit production, biofertilizer B can be used for a leafy crop, while biofertilizer C is good for the growth of roots and stem of plants.
