Keeping your garden fertile is the number one concern for most gardeners, and phosphorus is important to maintaining that fertility.

Ensuring they have the right amount of phosphorus not too little and not too much makes all the difference.

Which Fertilizers Are High Phosphorus? | Buy Phosphorus Fertilizers online

Synthetic fertilizers like ammonium phosphate have the highest overall phosphorus content. However, there are many organic options, including bone meal, fish emulsion, manure and compost.

Why Use A High Phosphorus Fertilizer?

Phosphorus is a key element in plant growth, and one that’s removed from the garden every time we mow, discard autumn leaves or or harvest our delicious crops. In order to keep on growing, we need to replace what we take away.

What Is Phosphorus Made Of? Buy Phosphorus Fertilizers for sale

Phosphorus is an element, and it makes up about 0.1% of the Earths crust. There’s a lot to go around! Plants aren’t the only ones who need it – it’s critical to all life on Earth . Fertilizers that contain phosphorus often take advantage of its importance in the body and source it directly from plant or animal waste. Hair, feces and even the decomposing bodies of animals are rich in phosphorus, and many commercial fertilizer draw from such sources.

Do All Fertilizers Contain Phosphorus?

Not all fertilizers contain phosphorus. Many are designed to target specific nutrient deficiencies, soil conditions or growth requirements instead. When purchasing a fertilizer consider the NPK ratio of the product. Printed on the front of the bag or bottle, the NPK tells us what percentage, by weight, of each element is present. It’s the P value to watch if you’re hunting a high phosphorus fertilizer.

High Phosphorus Fertilizers

Ammonium Phosphate | Order Phosphorus Fertilizers in bulk

Probably the easiest and most straightforward of the synthetic phosphates is ammonium phosphate. It’s a powerful source of nitrogen and phosphorus, applied as a granule or added to water to form a liquid. It’s commonly used in agriculture, and is popular among those of us yearning for a smooth, uniformly green lawn.

Rock Phosphate | Buy Phosphorus Fertilizers wholesale

Rock phosphate is the most common source of phosphates in blended commercial fertilizer. If you’ve slapped some Miracle Grow on the lawn, you’ve used a product that was once rock phosphate. It’s also sold in its pure form, a granule derived from sedimentary rock. It’s powerful stuff, clocking in at almost a full third its weight in phosphorus.

Hair | Buy Phosphorus Fertilizers for sale

Next time you brush your hair, think twice before you discard any stray strands. A quarter or so of its weight is phosphorus, and it also contains loads of nitrogen, calcium, magnesium and iron. Hair is  rich in phosphorus at a quarter phosphorus by weight. It’s also essentially free, especially if you have a big fluffy dog like a malamute, or a family with luscious, flowing locks.

Bone Meal | Buy Phosphorus Fertilizers cheap

Bone meal is exactly what you’d imagine – ground up bones. Very gothic! The bones are sourced from slaughterhouses, heat treated to kill pathogens, then milled into a fine, usable powder. I love using bone meal in the garden. It releases well, not too fast and not too slow, and it’s rich enough that only a few handfuls are needed at a time.

Bat Guano | Buy Phosphorus Fertilizers from wholesalers

Bat guano is rich in phosphorous at about 10% by weight. It’s also rich in nitrogen, potassium and other trace minerals. While useful, it’s not something most people have ready to hand, and even if you do know where the bats sleep it’s not great for your health to clamber over piles of raw bat poop.

Fish Meal

Fish meal is much like bone meal, made from ground up leftovers taken from fish processing plants. It too is heated and dried, producing a fine grainy material that’s stable and easy to use. While there’s a bit of variability between brands, fish meal usually has a NPK of around 10-6-2.Besides the phosphorus, it contains good quantities of nitrogen, and other trace minerals like calcium and magnesium.

Manure

Like worm castings, manure from farm animals is an excellent source of nutrients for the garden. Some manure from livestock is quite high in nitrogen compared to phosphorus. Others are more balanced, or contain little nitrogen at all.

Worm Castings

Sometimes referred to as vermicompost, are the droppings of worms, produced in worm farms. You may know the smaller domestic worm farms that feature several trays, one on top of the other like an apartment block. Worm castings are a great amendment. Besides being fantastic for use with indoor plants and container gardening, it’s also compact way for people in apartments, condos and the like to reuse kitchen scraps and plant waste.

Fish Emulsion

A more complex product than fish meal, fish emulsion is liquified and chemically stabilized by product of the seafood industry. Besides the excellent amount of phosphorus it provides, it contains a modest but balanced amount of nitrogen and potassium. Ratios vary from product to product, but typically hover around 2-4-1.

Compost

The overall phosphorus value of your compost will depend a lot on what you put in it. Add a lot of clean hair and manure, and encourage the worms to move in, and you’ll have a rich, sustainable plant food second to . It’s easy to get started, but a lot of fun to perfect, and I really encourage anyone with the space to give it a go.

Bloom Booster

“Bloom boosters” are commercial fertilizer blends marketed to gardeners with extravagant promises of abundant flowers, lush foliage and branches just heaving with fruit. They are almost always synthetic, made to proprietary formulas that vary wildly between brands. They’re often full of phosphates commonly used in heavy agricultural fertilizer, with as much as 56% phosphates.
