The Best Natural Phosphorus for Plants: How to Get the Most Out of Your Soil

Did you know that phosphorus is one of the most important nutrients for plants? If you want your plants to thrive, it’s important to give them the best possible soil. One of the most important nutrients for plants is phosphorus.

Unfortunately, phosphorus is often depleted from the soil due to natural erosion and human activities. This can be a major problem for farmers and gardeners.

Luckily, there are many natural sources of phosphorus that you can use to enrich your soil. In this blog post, we will discuss how to get the most out of your soil by using natural phosphorus sources!

Phosphorus is one of the three primary nutrients needed for plant growth.

It is an essential element, meaning that plants cannot survive without it. Plants use phosphorus to make energy through photosynthesis and respiration; it’s also used in cell division, DNA production, and protein synthesis.

The best way to get phosphorus into your soil is through the use of organic matter such as manure, compost, or leaf litter. This can be added directly to the topsoil where it will slowly break down over time and release its nutrients into the soil.

This method works best because phosphorus moves very slowly in water so adding it directly onto heavy clay soils may not be absorbed correctly.

There are many organics around your household that you can use to boost up the phosphorus in your garden naturally.

Natural Homemade Fertilizer To Increase Phosphorus

Fish emulsion and hydrolyzed liquid fish are both great natural sources of phosphorus for your garden.

To make a fertilizer solution with phosphorus, mix one tablespoon of fish emulsion or hydrolyzed liquid fish into one gallon of water.

Then spray the solution onto your plants’ foliage and around their roots, or use it as a soil drench to improve your garden’s phosphorus levels.

Be sure to test your soil’s phosphorus levels before adding any kind of fertilizer, to make sure you’re not overdoing it. Too much phosphorus can actually be harmful to your plants!

Bone meal

Need a source of phosphorus for your garden? Try bone meal, an excellent natural fertilizer that is high in phosphorus and adds calcium to the soil as well! You can either use it as a topdressing or mix it in with the soil before planting. To use as a topdressing, sprinkle it around the base of your plants and water well.

For best results, apply bone meal every few weeks. If you are mixing it in with the soil, work it in with a spade or other garden tool. Do not use bone meal on acid-loving plants such as tomatoes, blueberries, or azaleas.

Bone meal can be used to fertilize trees and shrubs. Apply the fertilizer directly onto the soil around the tree, working it into the top layer of dirt without disturbing any roots.


Manure is a great source of phosphorus for plants. It can be used as a natural, homemade fertilizer to increase the amount of phosphorus in your garden. There are many different types of manure, so be sure to choose one that is high in phosphorus.

Compost is a great way to increase phosphorus levels in your garden. It is also a great way to recycle organic matter and add nutrients to the soil. You can make compost at home with just a few simple steps.

To make compost, you will need:

  • A container for your compost pile
  • Organic matter (leaves, grass clippings, food scraps)
  • Water (rain or tap water)
  • A shovel or pitchfork

Place your container on even ground and fill it with organic matter. If possible, try to keep the material moist but not wet. This will help break down the materials more quickly.

Add more water if necessary and mix everything together with your shovel or pitchfork. Turn the pile every few days to help it break down.

After a few weeks, you will start to see a black liquid form at the bottom of the container. This is called compost tea and it is full of nutrients that your plants will love! You can use this tea as a foliar spray or water it directly into the soil around your plants.

If you do not have a container to make compost, you can simply pile up leaves and grass clippings in one area of your yard. This will take longer to break down but it will still provide nutrients for your garden beds over time.
