Why do we add fastillizens and manures to the soil
Answers
Answer:
Manures and fertilizers help in conserving and enriching the fertility of the soil. By growing plants again and again on the same soil, the soil becomes deficient in nutrients. Thus it is necessary to replenish the soil with these nutrients. That's why farmers add manures and fertilizers to the field

Explanation:
Soils naturally contain many nutrients like nitrogen, phosphorous, calcium, and potassium. These nutrients allow plants to grow. When soil nutrients are missing or in short supply, plants suffer from nutrient deficiency and stop growing. When the nutrient level is too low, the plant cannot function properly and produce the food necessary to feed the worlds’ population.
Once crops are harvested for human consumption, the natural supply of nutrients in the soil must be “re-filled”. This is why farmers add nutrients to their soils. Nutrients can be added from a variety of sources—organic matter, chemical fertilizers, and even by some plants. This maintains the soil fertility, so the farmer can continue to grow nutritious crops and healthy crops.
Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Fertilizers are simply plant nutrients applied to agricultural fields to supplement required elements found naturally in the soil. Fertilizers have been used since the start of agriculture. Native American people used crude fertilizers, such as burying a fish in their corn plots, and organic farmers use fertilizer from natural source, such as compost. Most farmers today use fertilizers that are either mined or manufactured.
