Why is fertilizer important

Commercial and consumer fertilizers are strictly regulated by both individual states and the federal government to ensure that they are safe for the people who use them, people nearby, and the surrounding environment.

With the global population steadily growing, it is important that enough crops are produced each year to provide food, clothing and other agricultural products to people around the world. Crops such as corn, wheat and cotton receive nutrients from the soil they are grown in; various crops deplete soil nutrients in different ways and rates.

Some crop growth can deplete soil nutrients after just a few seasons of planting. Fertilizers play an important role in providing crops with the nutrients they need to grow and be harvested for nutritious food. But they can do even more. A class of fertilizers called micronutrient fertilizers is engineered to enrich crops with vital nutrients that help support human health.

For example, micronutrients such as zinc are important to human nutrition, especially children. User Menu. Interactive Search. Popular Articles. When was the first house built?

In nature, the nitrogen, phosphorous and potassium often come from the decay of plants that have died. In the case of nitrogen, the recycling of nitrogen from dead to living plants is often the only source of nitrogen in the soil. To make plants grow faster, what you need to do is supply the elements that the plants need in readily available forms.

That is the goal of fertilizer. Most fertilizers supply just nitrogen, phosphorus and potassium because the other chemicals are needed in much lower quantities and are generally available in most soils. Nitrogen, phosphorus and potassium availability is the big limit to growth. The numbers on a bag of fertilizer tell you the percentages of available nitrogen, phosphorus and potassium found in the bag.
