What is the Role of Fertilisers in Increasing Agricultural Productivity?

Explore how fertilizers are pivotal in boosting agricultural productivity and crop health for higher yields.

Fertilizers play a vital role in increasing agricultural productivity nowadays. There is a deficiency of nutrients like phosphorus, nitrogen, and potassium in the soil. Fertilizers contain these elements, which overcome agricultural issues to some extent. On the contrary, agricultural issues can create devastating impacts on society. These impacts include food insecurity, hunger, unemployment and poverty. However, fertilizers are made through various processes, and we get high and fast agricultural growth as a result.

Furthermore, fertility also increases the productivity of land. What is Fertility? Fertility is the production of crops per unit area. There are some factors on which fertility depends a lot. These factors include seeds, environment, and soil. In this article, we will discuss the working, significance, impacts, different processes, and types of fertilizers.

What are fertilizers?

When the soil has a deficiency of nutrients, we need to have fertilizers. You can prepare these fertilizers in the industry or find them naturally. Fertilizers are nutrient-rich compounds that increase the fertility of soil. Fertilizers contain essential nutrients such as primary, secondary, and tertiary. However, primary nutrients are nitrogen, phosphorus, and potassium (N, P, K), while secondary nutrients are calcium, magnesium, and sulfur. In addition to these, tertiary nutrients are boron, molybdenum, manganese, iron, zinc, and copper.

Classification of fertilizers

Fertilizers are classified on the basis of their properties. These include nitrogenous fertilizers, phosphoric fertilizers, double nutrients, and potash fertilizers.

Nitrogenous Fertilizers	Urea, Ammonium Nitrate and Ammonium Sulphate
Phosphoric Fertilizers	Super Phosphate, TSP, and SSP
Potash Fertilizers	Potassium Nitrate
Double Nutrients	Di-Ammonium Phosphate DAP

How do Fertilizers Play a role in increasing Crop Yield?

Fertilizers are important in the growth of plants. Because nutrients like chlorophyll are essential for plants’ photosynthesis. Moreover, these fertilizers also ensure the smooth supply of nutrients in the soil. Primary nutrients are mandatory for the high yield of growth within a short period of time. Similarly, when fertilizers are applied to the crop, they gradually release the essential nutrients and manage the PH of the soil. In this way, chemical processes in plants are being controlled.

Additionally, the nutrients like nitrogen, phosphorus, and potassium increase the photosynthesis in plants. It increases plant health and overall productivity. In this manner, a fertilizer is significant to increase the crop yield and, eventually, agricultural growth.

Nutrient Requirement in Agriculture

Nutrients play a vital role in agricultural productivity by increasing the fertility of the soil. Here, we will discuss the role of all essential nutrients for plants.

How do Primary Nutrients increase the Fertility of Soil?

The fertility of soil can be increased by the primary nutrients. Each crop needs to have nutrient content. For example, nitrogen promotes protein synthesis, chlorophyll formation, and rapid growth. Similarly, phosphate promotes seed formation, stimulates blooming and early root growth, and hastens maturity. Potassium has the ability to resist disease and drought. Moreover, it increases the quality of grain, quality of seed and promotes stalk and straw strength.

Nitrogen (N)
Potassium (P)
Phosphorus (K)

How do Secondary Nutrients Increase the Fertility of Soil?

Secondary nutrients have similar significance as primary nutrients. These nutrients are supplied in moderate amounts. Calcium has the ability to resist seedling disease. It promotes root formation, stiffness of vigor, and straw. Similarly, magnesium promotes phosphorus metabolism and chlorophyll formation. Sulphur contains amino acids and vitamins that promote seedling production and imparts dark green color. On top of that, they can limit the production of crops.

Calcium (Ca)
Magnesium (Mg)
Sulphur (S)

How do Micronutrients Increase the Fertility of Soil?

These nutrients are helpful in the growth of plants and roots. For example, iron is important in the formation of chlorophyll in plants. Similarly, zinc acts as a plant regulator, which increases the growth of roots. Keep one thing in mind: access to micronutrients can be toxic to the fertility of soil. Boron is helpful in carbohydrate transportation and cell division. Copper acts as an enzyme and aids light reactions. Moreover, manganese aids oxidation-reduction reactions and hastens germination and maturation.

Boron (B)
Manganese (Mn)
Nickel (Ni)
Chlorine (Cl)
Iron (Fe)
Zinc (Zn)
Copper (Cu)
Molybdenum (Mb)

Role of Natural/Organic Fertilizers in Plant Growth

These fertilizers are organic products that you can extract from the earth and living organisms. Natural fertilizers have the potential to increase the productivity of land. These include Vermicompost, Bone Meal, Chicken Litter, Rock Phosphate, Compost, and Manure.

Organic fertilizers have the potential to enhance the microbial activity of soil. Indeed, these fertilizers increase nutrient mineralization rates, which are beneficial for the crops. Organic fertilizers gradually provide suitable nutrients to the soil. These include Blood Meal, Mushroom Manure, Bone Meal, Horse Manure, and Bone Meal.

Role of Synthetic/Inorganic Fertilizers in Plant Growth

These are nutrient-rich fertilizers that play a vital role in the healthy growth of plants. This factor leads you to get a high yield. These include ammonium nitrate, ammonium Sulphate, and ammonium Phosphate.

Inorganic fertilizers are prepared in the industrial sector and release nutrients in the soil. These nutrients include potassium, phosphorus, and nitrogen. This is how you can increase agricultural productivity with the help of inorganic fertilizers. However, over-supply of inorganic fertilizers increases the PH level of soil and makes it more acidic. Therefore, it is necessary for you to release these fertilizers in the soil in a limited amount.

Urea ( 46,0,0)
Ammonium Nitrate ( 34 0 0)
Potassium Nitrate (13 0 44)
Urea-Ammonium Nitrate Solution
Triple Superphosphate (0 46 0)
Monoammonium Phosphate (11 48 0)
Diammonium phosphate (18 46 0)

What are the Advantages of Using Fertilizers in Agricultural Growth?

Agricultural productivity is essential to sustain the economy of any country. The agricultural sector is considered to be the backbone of one’s country. Fertilizers are the key elements, as we disclosed above. Here are some of the effective pros of agricultural growth.

Nutrient Balance: Nutrient balance is very important for plants. Overdose or deficiency of nutrients leads to poor yield of any crop. Hence, fertilizers fulfill the nutrient demand of soil to directly impact plant growth and yield.
Save land Use: Fertile land is very rare and important for any country. Fertilizers can save excessive land use with high output. For example, you can increase any crop productivity by 2x just by the use of fertilizers in small land areas rather than larger ones.
Prevents Underground Water Reserves: Fertilizers not only increase the fertility of land but also prevent underground water reserves. This can lead to saving unwanted drought and disease.
Environmental-Friendly Practice: Proper and managed use of fertilizers decreases environmental impacts like water pollution and promotes best agricultural practices.
