Water passing through the soil leaches basic nutrients such as calcium and magnesium from the soil.

Work the two soil amendments into the top 8 to 12 inches of soil using a spade or tiller. Water the garden thoroughly to allow the nutrients to begin the process of being absorbed throughout the bed. Soil sampling depth – Since phosphorus is not mobile in soil, samples that are taken from the topsoil will usually indicate higher amount of phosphorus than samples that are taken from the subsoil.

There are several methods used by various soil testing labs for determining how much phosphorus soils can supply to the crops we grow in them. Many commercial blends contain micronutrients. A professionally conducted soil test will tell you not just your garden's current levels of nitrogen, phosphorus and potassium but also whether the soil is noticeably lacking in any of the micronutrients. In fact, phosphorus and potassium represent the last two numbers of those bags of 10-10-10, 5-20-20 and so forth that you see in the garden center. Choose a blend that has at least as much phosphorus and potassium (the second two numbers) as nitrogen (the first number), such as 10-10-10. In working to moderate phosphorus levels in the garden, it will be imperative that growers avoid the use of fertilizers that contain phosphorus. Cover crops and green manures can also contribute to phosphorus availability in many conditions. It will break down quickly when mixed in. Applying lime to very acidic soils is always a good idea, and one of the benefits of that is to help phosphorus become more available even without adding it as a supplement. The most effective methods of adding phosphorous to your soil include: In conclusion, you can see it’s fairly simple to ensure you have a balanced amount of phosphorous in soil. This publication covers essential scientific information about phosphorus and how it behaves in soil, current concerns about phosphorus runoff from agriculture, and how farms can manage this nutrient. Since high phosphorus content prevents soil absorption, you can use a sprayer to apply a solution of these minerals to plant leaves. This is one of the building blocks of the NPK fertilizer trio. Test your soil with a soil test kit afterwards to verify the success of this method.

P activators can increase the availability of this P to plants by accelerating its transformation into soluble P fractions. Fertiliser phosphorus does not move far from where it is applied because it reacts rapidly with soil. Thus, P-deficiency stunts vegetative growth and grain yield. In comparison to other macronutrients, the phosphorus concentration in the soil solution is much lower and ranges from 0.001 mg/L to 1 mg/L (Brady and Weil, 2002). Soils developed from basic rocks generally have higher pH values than those formed from acid rocks. Granite meal is especially high in silica for example. Coffee has some nitrogen that slowly releases into the soil. Plants need phosphorus to stimulate root growth and to set flowers and fruits. Careful with this method as you will also leech other key nutrients away as well.
