Detailed explanation-1: -They are known as “bio fertilizers”. Thus bio-fertilizers are living or biologically active products or microbial inoculants of bacteria, algae and fungi (separately or in combination) which are able to enrich the soil with nitrogen, phosphorus, organic matter etc.
Detailed explanation-2: -Without nitrogen, most of the world’s crops wouldn’t exist. Nitrogen is to corn, wheat and rice, what water is to fish. Yearly, more than 100 million tonnes of nitrogen are applied to crops in the form of fertilizer, helping them grow stronger and better.
Detailed explanation-3: -To retain soil fertility it is necessary to replenish nutrients by returning to the soil at least the same amount. So we use fertilizers which contains the essential nutrients. Fertilisers provide plants with the essential chemical elements needed for growth particularly nitrogen, phosphorus and potassium.
Detailed explanation-4: -Nutrients can be replenished in the following ways: Fertilisers and manures contain plant nutrients such as nitrogen, phosphorous and potassium, etc. So, when fertilisers and manures are added to the soil in the fields, then the soil gets enriched with nutrients like nitrogen, phosphorous and potassium, etc.
