Fertilizers are an important part of plant nutrition by supplying the needed nutrients for growth and development. Some of the most important nutrients such as nitrogen, phosphorus, and potassium enhance important functions such as root development, flower and fruit development, and overall plant health. Fertilizers are used in gardening and agricultural purposes to help correct nutrient deficiencies in the soil and supply the nutrients that plants require to produce the best possible results. Plants must have an adequate supply of nutrients in order to produce healthy leaves, strong roots, and plenty of flowers and fruit. Fertilizers ensure an adequate supply of nutrients and will allow plants to grow most efficiently when used appropriately. Without adequate fertilization, plants may exhibit poor growth (e.g., reduced amount of roots), yellowing leaves and produce fewer yields. This situation is especially critical for farmers, who generally depend on fertilizer to increase crop production since soil will become deficient in nutrients over years of agricultural use. 

Using fertilizers may not only support the development of healthy plants but can also reduce the impact of plant agriculture on the land, by allowing existing farmlands to maintain their productivity. Fertilizers represent a tool for increasing and maintaining the productivity of our food supply while allowing farmers to manage their soil to support growing plants at the same time. Thus fertilizers represent a vital tool in promoting healthy plants, food crop yield and our ability to provide for food production.

Why Fertilizer Is Important for Plants

Fertilizer is an important component of growing or developing plants. Fertilizer is made to replace nutrients that may be lacking in soil in order to improve growth, increase yields, and help overall health of the plant. 

Providing Essential Nutrients for Plant Growth

Plants need nutrients to grow. These include macronutrients (N, P, K - nitrogen, phosphorus, potassium – the "NPK") and micronutrients (iron, zinc, copper). Most nutrients are important to processes like cell division, development of roots, producing flowers/fruits, etc. Fertilizers help replace nutrients that the plant takes from the soil, especially when soil quality is poor or when nutrients in the soil have become depleted due to the constant use of the plots for cropping. 

Boosting Photosynthesis and Plant Functions

Of the processes that plants participate in, photosynthesis is an important one. Photosynthesis is how plants convert light into energy for many of their functions. Nitrogen is one of the nutrients found in most fertilizers - nitrogen is necessary for chlorophyll which functions to help the plant photosynthesize. Fertilizers help increase what happens in photosynthesis and nutrients are used more efficiently. This leads to overall healthy and quicker growth and ultimately green plants, healthy plants.

Supporting Root Development and Disease Resistance

Fertilizers are responsible for supporting above ground growth in plants but they are also crucial for producing strong and healthy root systems. Phosphorus is an essential ingredient in most fertilizers and directly helps stimulate root development and in energy storage. Fertilizers also can influence the plant's health, and in this sense can improve a plant's ability to resist pests and diseases. Plants receive adequate nutrition that can better resist being affected by pathogens. 

Why Is Fertilizer Important for Agriculture?

Fertilizer is significant in agriculture because fertilizers provide nutrients that are necessary for growing plants. Through the process of planting crops year after year, soil can become depleted of essential nutrients. Fertilizers also help re-stimulate the biological processes within the soil, which leads to healthy production of crops and improved agriculture production.

Maximizing Crop Yields and Food Security 

The utilization of fertilizers has an impact on crop productivity. And here is how to optimize yields and food security: 

• Improved Plant Growth: Fertilizers provide the essential nutrients plants need to build root systems, leaves, and fruit or seeds all of which are essential to achieve crop yields. 
• Increased Resistance to Stress: Fertilizers provide plants with the extra ability to improve its natural resistance against pests, diseases and environmental stress. Healthy plants are generally better able to survive growth conditions that are not ideal, and supports food security. 
• Improved Land Use: Fertilizers also allow greater production of food from the same land, which when using fertilizers does not require land clearing or conversion, both of which are important in maintaining ecosystems and carbon absorption to combat climate change and reducing greenhouse gas emissions.

Enhancing Soil Fertility for Long-Term Growth

Soil fertility is important for long-term agriculture productivity. Fertilizers are a way in which soil fertility increases over time: 

• Replacing nutrient demands: When a crop is grown, it will take nutrients out of the soil when it grows. If a crop continues to be grown on the same ground, it is obvious that some of the nutrients in the soil will need to be regularly replaced. Fertilizers replace the nutrients that the plant needs to grow. If the soil in which crops are grown has not nutrients, then the land is a poor place to grow crops, and you will not have a continuous supply of healthy crops. 
• Reducing soil pH: Fertilizers help add to the balance of soil pH. Soil pH needs to be balanced for a contingent to maximize plant growth. Soil pH is important for soil nutrients to be available to plants.
• Erosion on the soil microbial activity: Fertilizers support favourable microorganisms, which impact the rates of organic matter decomposition in soils. Healthy soil microorganisms provide the structure and function of soil, which can greatly enhance the long-term fertility.

Supporting Sustainable Farming Practices

Fertilizers are essential for the sustainability of farming practices. Here’s how they help make farming practices sustainable:

• Efficient Nutrient Management: Fertilizers help people efficiently manage nutrient availability. Additionally, proper timing and method of potato fertilizers will ensure that they can mitigate the risks of over-fertilizing while managing nutrient runoff. It also helps reduce the risk of nitrogen being leached away by nature so the soil contains nutrients that can be used to grow healthy plants.
• Water Conservation: Fertilizers also help the plant use water efficiently, which is critical where water is a limited resource. Crops that are well nourished are more resistant to drought and can utilize available water resources better.
• Bottom-Up Environmental Sustainability: Nitrogen fertilizers - especially if applied in a sensible way - will help reduce the demand for new agricultural land, which will help mitigate deforestation, which will help preserve the environmental ecosystems leading to sustainability.
