Detailed explanation-1: -Many farmers use NPK compound fertilizers that provide a combination of several nutrients at the same time. Organic fertilizers such as animal waste and compost have been used for centuries and are a valuable source of nutrients and organic matter, which enhances soil structure.

Detailed explanation-2: -Fertilizers are added to crops in order to produce enough food to feed the human population. Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food.

Detailed explanation-3: -Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element.

Detailed explanation-4: -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-5: -Farmers apply nutrients on their fields in the form of chemical fertilizers and animal manure, which provide crops with the nitrogen and phosphorus necessary to grow and produce the food we eat.
