As the world's population continues to grow, the demand for food becomes increasingly important, which results in the use of chemical fertilizers. Chemical fertilizers are used in agriculture to increase crop yields and provide essential nutrients to plants, but they contain harmful chemicals that can have negative effects on the environment, such as degrading soil, reducing fertility, increasing pest resistance, causing heavy metal precipitation in soil, etc., and also have been linked to health problems such as cancer, birth defects, etc. To address these negative effects, there has been a growing movement towards sustainable agriculture practices, such as organic farming and regenerative agriculture. These practices prioritize soil health, crop diversity, and natural pest control methods, which can reduce the need for chemical fertilizers and promote more sustainable food production. Household vegetative waste management has been a major issue in most urban communities. Cow dung causes unpleasant odours, pollutes the environment, can become vectors of disease, and produces the largest greenhouse gas emissions, such as methane gas (CH4). Biofertilizers are basically microbial inoculants that, when applied to soil, plants, or seeds, boost plant growth and development by increasing the delivery of vital nutrients or chemicals that promote plant growth, as well as increasing soil fertility. PGPR colonizes plant roots and stimulates plant development through a number of processes, such as phosphate solubilization, phytohormone synthesis, antifungal activity, and others. So, the preparation of biofertilizers from household vegetative waste and cow dung (used as a carrier) by using the co-inoculum of PGPR could be an alternative to all existing problems arising due to the use of chemical fertilizers. This review describes problems occurring due to chemical fertilizer, household vegetative waste, and cow dung, and solutions to the problem, i.e., biofertilizer, and the use of PGPR for sustainable agriculture.
