Phosphorus will help boost your garden soil fertility. So, if you’re looking for ways on how to add phosphorus to your garden soil naturally, then this is it.

The three major macronutrients that are essential for plants growth are nitrogen, phosphorus, and potassium. Then each of these macronutrients has a very essential role to play in the development of a plant. Phosphorus is one primary nutrient that plants always tend to search for to stay healthy and flourishing.

For the purpose of this article, we will be focusing on phosphorus and how you can add this macro-nutrient to your soil naturally. So, continue reading to gain adequate knowledge on this.

The Need For Phosphorus In Plant Soil

The need or importance of phosphorous in the soil cannot be understated. For a plant to grow healthily phosphorus is one of the main ingredients to achieve this.

The role of plant reproduction is engineered by the element phosphorus. This is because phosphorus is a crucial component in the nucleic acid of a plant’s DNA. Therefore, phosphorus can help boost the yield, quality, and rate at which your crop develops.

The main essential nutrients of plant soil are NPK (nitrogen, phosphorus, and potassium). Even though the overall phosphorus content of most soil surfaces is low (about 0.6%) compared to the average soil content of other essential macronutrients of 0.14% of nitrogen and 0.83% of potassium.

The Need For Phosphorus In Plant Soil

However, the content of phosphorous in the soil can vary. It can range from less than 0.04% in the sandy soil of the Atlantic and Gulf coastal plains to more than 0.3% in the soil of the northwestern US.

Also, different factors can influence the content of phosphorus in your garden soil. Some includes:

    • The climate conditions.
    • The rate or degree of erosion and weathering.
    • Fertilization as well as the removal of crops.

Phosphorus Rich Fertilizer

Gardeners are familiar with the general NPK fertilizer. This NPK fertilizer comes in different ratios that are suitable for plants’ growth. The NPK fertilizer will supply the essential nutrient needed by the plant and these nutrients include nitrogen, phosphorous, and potassium.

There are also other natural phosphorus fertilizers that are rich in phosphorous. We will be listing them below in this article.

Natural Sources Of Phosphorus For Plants

Natural phosphorus for plants is a good way of organically or naturally supplying phosphorus to your plant for proper growth. There are many ways on how you can add phosphorus to your soil naturally.

Nature has supplied us with different sources or ways of adding phosphorus to our garden soil. The natural sources of phosphorus that we can make use of in our garden soil can be found in: bone meal, shrimp and crab waste, hair and mushroom compost, burned cucumber skins, rock phosphate, organic compost, manure, guano, and so on.

How To Add Phosphorus To Soil Naturally

So, let’s look into some of these natural sources of phosphorus.

  1. Bone Meal: the addition of bone meal to your garden soil is a great way of adding phosphorus to your soil naturally. Bone meal is derived from grinding the bones of animals and this is very rich in phosphorous.

  2. Organic Compost: another natural way of supplying phosphorus to your garden soil is by the application of organic compost.

  3. Manure: just like organic compost, manure addition can also help enhance phosphorus content in your garden soil.

  4. Rock Phosphate: rock phosphate can also help increase phosphorus in soil naturally. However, it is slow releasing and the soil will require converting the rock phosphate into phosphorous that is usable to plant.

  5. Clay Soil: when you incorporate or introduce clay particles into the soil, it can help fix and retain phosphorus deficiencies.

Importance Of Phosphorus In Soil

Here is some importance of phosphorous in plant soil:

  • Component of DNA and RNA: it is a very important component of genetic DNA and RNA. The phosphorus bond is what links the structure of both DNA and RNA.

  • Root Growth: the growth of your plant’s roots will be strengthened with the application of phosphorous. The strength of the plant stalk will also be enhanced.

  • Component of ATP: the energy unit of the plant comprises phosphorous. Formed during photosynthesis is phosphorus in the ATP.

  • General Health: phosphorus is important when it comes to the general health and vigor of all plants. Phosphorous will offer good support throughout the entire life cycle of your plant. it also early crop maturity.

  • Reproduction: phosphorus plays a vital role in the reproduction of plants because it is an essential component in the nucleic acid of a plant’s DNA. Therefore, you have an increase in crop yield, the quality of the crop is enhanced, and the rate of crop maturation is improved with phosphorous.

  • Flower and Seed Formation: with the appropriate phosphorus supply, your plant’s flower formation and seed production is enhanced.

Result Of Phosphorus Deficiency In Plant

There are some things to look out for when it comes to deficiencies of phosphorous in plant soil. However, it isn’t that easy to detect phosphorus deficiency, unlike potassium and nitrogen.

Your crop may not even show any major signs of deficiency in phosphorus. However, one general sign you may notice is stunted plant growth in early growth.

Crops such as corn can exhibit an abnormal coloration when there is a deficiency in phosphorus. The plants usually turn or show dark bluish-green coloration and the leaves and stem turn purple. Genetic makeup influences the degree of purple and some hybrids can exhibit greater discoloration than others.

What is the best natural source of phosphorus for plants?

I think that the best source of phosphorus is manure. It is well known that bat guano is the best source, and if you can get it you can really treat your plants. I would not recommend adding it to compost because phosphorus is released as a result of decomposition, and the composting process itself will release phosphorous into the air. I would also not recommend adding it directly to the soil, as it will make the soil acidic, which is probably not what you want.

How do you make natural phosphorus fertilizer?

Phosphorus comes from rocks such as rock phosphate, phosphoric acid, and phosphoric anhydride. Phosphorus is released by rocks when they are exposed to water and sunlight.

Making natural phosphorus fertilizer is a two-step process. The first step is to add organic matter to the soil, and the second step is to add phosphorus in a form that can be absorbed by the soil. Keep Learning Adding organic matter to the soil is important because it provides a substrate for microbes to grow on and break down the phosphorus in the soil. Adding phosphorus to the soil is important because plants require phosphorus to grow.

You can also mix ground-up red worms with manure or compost. The red worms absorb the phosphorus in the manure or compost, and then they excrete a phosphorus-rich liquid that can be used as a fertilizer. Red worm composting is not common in the United States, but it has been used in China for over 2,000 years.

What are common things that you can add to soil to increase phosphorus?

Phosphorus is not an issue of having too much or too little in your soil. You have the correct amount of phosphorus already. The problem is that it is tied up with calcium and aluminum, both of which are in low concentrations. You can add phosphorus to the soil by adding rock phosphate, limestone, or dolomite. These can be purchased at any farm supply store, or a fertilizer company will sell them.

The best way to apply these materials is to add them to your irrigation water before it goes to the plants. A slow-release fertilizer like Calcium Nitrate. is also a good way to add phosphorus to your garden. It is sold by most fertilizer companies in bags or as a liquid. If you are using a bag, make sure that it does not contain fertilizer that has been mixed with ammonium nitrate, which is explosive. If you would like to try adding phosphorus to your soil, you may want to do this when your garden is not growing vegetables. You can apply a small amount of phosphate rock to each bed, but it is better to spread the rock over a wider area than just the beds. When you apply phosphate rock to your soil, it will become a part of the soil and will be available to your plants. It will not be washed away by rain or leached out by irrigation water.

Conclusion On How To Add Phosphorus To Soil Naturally

Phosphorus plays a vital role in the development of plants and overall plant growth. It will also assist in boosting your soil fertility.

From the above, we have seen how we can carefully add phosphorus to our garden soil naturally. There are so many benefits phosphorus can offer our plants. Then we have discussed how important phosphorus is to the growth of plants.
