Plants require phosphorus for their growth and development. However, there is not enough phosphorus available in the soil. For this purpose, phosphorus fertilizers are added to the soil to meet the plant requirements. They promote stem, root, and seed formation. They provide energy to plants through the photosynthesis process and protect against the pests. The deficiency of phosphorus may lead to different issues in the plant growth.

In this article, I am going to share information about phosphorus fertilizers, their importance in plants, and the working of phosphorus fertilizers. Moreover, it includes the benefits, roles, and types of phosphorus fertilizers with respect to crop yield. 

Role of phosphorus fertilizer in plants and crop yield

phosphorus fertilizer in plants and crop yield

Phosphorus is the main element that is required in the plants. The phosphide performs many roles in plant life. Some of these are:

  • Phosphorus is the main element of the RNA and DNA. These are helpful for building the proteins and essential for making the plant structure. The structures of the DNA and RNA are linked because of the phosphorus bonds.
  • These are essential from the formation time to the maturity of the plants.
  • They play an important role in the seed formation and growth. These are helpful in flower production.
  • It stimulates the root growth and development and provides strength to the stem.
  • Phosphorus enhances the nitrogen uptake ability of the plants.
  • It provides resistance to the plants against various diseases.
  • The overall crop yield is improved through the phosphorus fertilizer.

Total phosphorus content in the soil

The phosphorus content in the soil varies with the soil type. The climatic conditions, weather, and fertilization period all affect the overall content of phosphorus. In comparison to nitrogen and potassium the overall content of the phosphorus is lower in the soil. For most of the surface soils, there’s around 0.6% of the phosphorus present within the soil. In order to manage the requirements of the plant die Phosphorus fertilizers are used. 

How does phosphorus improve crop yield? 

The phosphorus clearly affects the improvement of the crop yield. They are proven for high crop yield. The presence of Phosphorus facilitates the overall growth of the stems and the roots directly improves the crop yield. Moreover, these are promotive towards crop uniformity. However, if the supply of the phosphorus is not enough for the plants it will reduce the growth of the plants.

  • The crop yield overall improved with time due to the presence of phosphorus. It actually promotes the root and shoot growth that actively increases the flowering and fruiting of the crops. 
  • These are necessary for plant growth because they promote cell division of the plants. 
  • With the passage of time, it increases the growth of the tips of the plants.
  • In the wheat plants, the wheat crops also increase the growth of the seed in the crops.
  • They directly improve the growth of most of the plants and directly affect their development.
  • They provide energy reactions and are important for developing the plant’s reproductive structure.

Phosphorus fertilizer types

Superphosphate (OSP) 

Concentrated Superphosphate (CSP)

Monoammonium Phosphate (MAP) 

Diammonium Phosphate (DAP)

Ammonium Polyphosphate (APP)

Rock phosphate 

  • Organic phosphorus fertilizers 

Organic Phosphorus fertilizers can also be used for the plants. Sewage, sludge, and compost are also good sources of phosphorus. These are easily decomposable in the soil. Basically, the manure contains 45 to 75% phosphorus in the fertilizers.

  • Synthetic phosphorus fertilizer

Synthetic phosphorus fertilizer

Synthetically there is no substitute for preparing or destroying the phosphorus. Moreover, there’s not any available synthetic version of phosphorus available. For commercial or synthetic fertilizers the rock phosphate is utilized for making and combining the phosphorus for synthetic fertilizers.

On a synthetic level, these are treated with the sulphuric acid. That forms the phosphoric acid as a resultant product. Afterward, it is mixed with the Ammonia to form the phosphate fertilizers

Organic fertilizers with high phosphorus content and best for crop yield

Although you can purchase synthetic fertilizers to fulfill the need for phosphorus. However, organic fertilizers process the right blend of nutrients that promote crop yields. They are environment-friendly and directly promote crop yield in a healthy way.

1. Blood and bone meal

These are the easiest and most important phosphorus sources for the plants. You can easily use these animal bones and blood to increase plant growth. These are inexpensive and good sources.

2. Chicken manure

Chicken manure is a high-energy source for the plants. The regular addition of the manure from time to time directly affects the plant growth in a positive way. 

Plants that require more phosphorus for growth

Mainly the plants in the early life stages require more phosphorus. Besides this, some of the other plants also require a high amount of phosphorus for growth. That is:

  • Annual plants
  • Cold weather plants
  • Legumes
  • Lettuce
  • Spinach

Methods to use phosphorus fertilizer that directly enhance crop yield

For high crop yield fertilizers can be applied by the following methods;

1. Root spray

The phosphorus fertilizers can be directly sprayed on the crop roots. Through this method, the phosphorus will penetrate within the plants quickly. This is mostly used when you don’t supply the phosphorus in the early growth period of the crops.

2. Combined application with nitrogen

For high crop yield, the phosphorus is also used along with the nitrogen. This positively affects the plant and crop yield. Their application balances the overall nutrient concentration within the soil and promotes plant growth and yields.

3. Used in combination with the Organic fertilizers 

The organic fertilizers are overall a good addition for the environment and plants. They are helpful for improving the nutrient uptake of the crops. With the combinations, the insoluble phosphorus can be made soluble. Mostly, it is used in combination with magnesium, calcium, manure, compost, and other organic fertilizers. 

4. Concentrated phosphorus application

The concentrated phosphorus is applied within the nearby holes and spaces with the roots. This form of phosphorus is mainly fixed by some of the available elements around it. Through this, it can easily fix the phosphorus inside the roots. This improves the soil quality, facilitates soil absorption, and directly participates in improving the soil structure and plant life.

5. Application in form of fine phosphate fertilizer

Some of the phosphate fertilizers are easy to apply in the fine powder form. Superphosphate is used as a fine fertilizer. Afterward, it is directly absorbed by the crops and affects their growth in a positive way.

Phosphorus deficiency effects on plants and crop yield

Phosphorus deficiency

Like other nutrients, it doesn’t show any symptoms in early life. However, they show symptoms when there’s no going back. In case of the phosphorus deficiency, some of the plants show abnormal discoloration. The abnormal discoloration is forming a dark blue or purplish color for the stem and leaves. The maturity of the plants and seed formation is effective for the plant life. The leaves start to curl in the limited phosphorus. Besides this, its deficiency results in stunted plant growth.

Excessive application of Phosphorus fertilizers on crop yield

When the Phosphorus is applied in an excessive amount the overall utilization rate for the fertilizers reduces over time. This will not increase crop yields. They actually reduce the crop yields due to the excessive application of the phosphorus. The plants can also die due to the high concentrations. 

Conclusions

Phosphorus is one of the major macronutrients that affects plant growth. Naturally, the phosphorus content in the soil is low. Due to this, there’s a need to use the phosphorus fertilizer. For this purpose, organic and inorganic fertilizers can be used to fulfill the phosphorus requirements. However, the way of application greatly affects crop growth. For a high crop yield, you must check and test the soil nutrient level and provide an adequate amount of phosphorus to the plants.
