Phosphorus is a soil nutrient that promotes root development and flower growth and therefore stimulates good crop production.

Some soils, however, are less in phosphorus content, which is why there is a need for artificial supplementation through the use of fertilizers and organic  materials. If you wish to add phosphorus to your soil, here are some tips.

Use commercial fertilizers. Phosphorus is one of the three key ingredients in fertilizers; the other two are nitrogen and potassium (The “NPK” label printed in fertilizer packaging stands for nitrogen, phosphorus, and potassium). If you prefer to use a commercial fertilizer, remember to carefully follow the instructions detailed in the label. and make sure to use only the required amount as if amount given to plant is more than the plants suffer.

Consider trying bone meal. Bone meal is rich in potassium. It can be purchased from your local garden or nursery store and comes in different forms. Bone meal can be applied as it is. But in some cases, it can be applied together with fertilizer. You can do this by mixing bone meal and fertilizer in a small pail. With your hands, mix them thoroughly until they are very well blended. Then, apply the mixture according to the instructions of the fertilizer manufacturer.Use gloves wile mixing bone meal and the fertilizer as its very important to wear gloves while handling any chemical based products.

Make a compost pile. The materials used in compost pile are high in phosphorus content. You can make a compost pile by collecting food and garden scraps. In a bin, place a layer of soil and top it with your compost ingredients such as egg shells, fruit and vegetable peels, coffee ground, tea bags, dry leaves, and plant trimmings. Then, put another layer of soil. Add a small amount of water. Close the bin. After every two weeks, remember to stir the compost. Then, when the compost has turned into a soil-like material, you can apply it to your soil.

Use rock phosphate. Adding rock phosphate to your soil is also beneficial. But unlike other phosphorus sources, rock phosphates may require a longer time to work. At any rate, it is effective in phosphorus supplementation. If you want to use rock phosphate, you only need to put around four pounds of rocks for every lot of 100 square feet. Consider adding more if your soil is severely deficient. Aside from applying rock phosphate directly to the soil, you can also add rock phosphate to your compost.

Whichever method you select for adding phosphorus but make sure that you have done the soil test first as it will determine the amount of phosphorus present in your and will help you know how much phosphorus to add. It can be performed in your local garden lab; the only thing you need to do is send soil samples. The test, of course, comes with a price, but it will provide you with information about your soil and possibly recommend ways to enrich your soil.
