The Different Types of Fertilizer Chemicals and Their Uses in Agriculture

You need about 3 min. to read this post

Fertilizers help ensure that your plants, flowers and trees get all the nutrients they need to thrive. But there are many different types of fertilizer chemicals, each with a specific purpose, that you’ll need to know about if you want to keep your garden growing strong. Here’s what you need to know about the three main fertilizer chemical groups and their uses in agriculture: the major fertilizer groups – nitrogen (N), phosphorus (P) and potassium (K); micronutrients – minor nutrients like iron and zinc; and specialty fertilizers – products used in small quantities or specific situations.

Nitrogenous Fertilizers

Nitrogen is an essential nutrient for plants as it is used to produce chlorophyll, amino acids, proteins, enzymes, and other compounds necessary for plant growth. Nitrogen can be found naturally in the atmosphere or applied as a chemical fertilizer which serves as a nitrogen source for plants. Three main types of nitrogenous fertilizers are ammonium nitrate, urea (NH2CONH2), and ammonia (NH3). Ammonium nitrate contains 21% nitrogen while urea contains 46% nitrogen. Ammonium nitrate has a slower release cycle than both urea and ammonia so it should be applied every 5 to 6 weeks while urea should be applied every 3 weeks and ammonia should be applied every week.

Phosphatic Fertilizers

Phosphate-rich fertilizers are often used on plants that require a lot of nutrients to grow, such as corn or soybeans, because the plants will quickly absorb these fertilizers. 

Phosphate fertilizers also help soil retain water better than soil without phosphates, so they’re sometimes mixed with other fertilizer types like nitrogen to improve their effectiveness. Phosphorus is an important nutrient for both people and animals alike, but excessive use can have negative effects. Excess phosphorus builds up in the ground over time, causing it to turn into a salty substance known as ‘hardpan.’ The saltiness then affects nearby freshwater resources by seeping into nearby groundwater supplies. Too much phosphorus can also harm human health by interfering with our body’s ability to break down food correctly, resulting in more acidic blood pH levels. That being said, high doses of phosphate fertilizers only pose risks when applied excessively or improperly–but there are still risks involved!

Importance of agriculture fertilizer products

Fertilizers are used to feed the earth. They provide plants with the nutrients they need to grow healthy, strong and beautiful. There are many different types of fertilizers, but there are two main categories: organic and mineral. Agriculture fertilizer products include compost, manure, cottonseed meal, blood meal or feather meal. Mineral fertilizers include nitrogen-based products like ammonium sulphate or urea, phosphorous-based products like mono ammonium phosphate (MAP) and potassium-based products like potash. Nitrogen is an essential nutrient for all green vegetation. Phosphorous provides a crop with energy to form leaves and flowers while Potassium is important for cell growth. Some fertilizers contain more than one type of nutrient because the right balance is essential for growing a healthy plant; this includes various combinations of nitrogen, phosphorous and potassium.
