The function of phosphorus in plants is very important. It helps a plant convert other nutrients into usable building blocks with which to grow. Phosphorus is one of the main three nutrients most commonly found in fertilizers and is the âPâ in the NPK balance that is listed on fertilizers.here is no understating the importance of phosphorus in plant growth. Without it, a plant simply cannot be healthy. The basic function of phosphorus makes it possible to have beautiful and abundant plants in our gardens.
A lot of the phosphorus in soils is also unavailable to plants. Soil phosphorus becomes unavailable to plants through several routes: 1  Bacteria: Bacteria convert plant-available phosphate into organic forms that are then not available to plants.2  Although other bacteria make phosphate available by mineralisation, the contribution of this is small.hosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Here are the key steps of the phosphorus cycle 1  : Over time, rain and weathering cause rocks to release phosphate ions and other minerals. 2  This inorganic phosphate is then distributed in soils and water.
