उत्तर
Microbes are highly useful in maintaining and restoring soil fertility. Soil fertility is determined by its chemical structure and the number and quality of beneficial bacteria. Furthermore, we add biologically derived elements to improve and maintain fertility when the soil’s composition is inadequate and fertility is low. These materials are classified into two basic categories: waste and biofertilisers. We classify wastes into three types: farmyard waste, compost, and green waste. Farmyard waste is the oldest dung known to human beings, consisting of farm animal excrement and plant remains, among other things, that are allowed to partially decompose with the help of soil micro-organisms. These microbes degrade complex organic waste into a dark, amorphous substance known as sludge, which plants can easily consume. Fertiliser dissolves in the soil, improves aeration, and makes it grow better. Biofertilizers are microorganisms that restore soil nutrient levels while maximising ecological benefits and reducing environmental risks.
