Phosphorus Deficiency in the Soil How can you tell if your garden has a phosphorus deficiency? The easiest way to tell is to look at the plants. If your plants are small, are producing little or no flowers, have weak root systems or a bright green or purplish cast, you have a phosphorus deficiency. Since most plants in the garden are grown for their flowers or fruit, replacing phosphorus in the soil if it is lacking is very important. When using chemical fertilizers, you will want to look for fertilizers that have a high “P” value.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 “P” in the NPK .
About 90% of the phosphoric acid produced is used to make fertilizers. It is mainly converted into three phosphate salts which are used as fertilizers. They are triple superphosphate (TSP), diamonium hydrogenphosphate (DAP) and monoammonium dihydrogenphosphate (MAP).
