Flower crops require fertilization program at its considerable contribution of esential elements. However, the availability of phosphorus in the soil is limited due to many factors. Soil acidity is one of the most important factors related to the availability of phosphorus for crops.The municipality of El Colegio and overall 80% of soils in Colombia are classified as acidic soils (pH less than 5.0), which limits the productivity of crops and especially flower growing Cymbidium.T1 (100% phosphorus), T2 (150% phosphorus), T3 (50% phosphorus), T4 (mycorrhizae) and T5 (absolute witness: a research with an experimental design of randomized complete block with the following treatments were developed. Additionally organs of Cymbidium like plants roots, bulbs, leaves and flowers on two phenological stages (vegetative and reproductive) was extracted, in order to observe distribution dynamics of phosphorus inside Cymbidium plants.Differences between the content of phosphorus in organs of Cymbidium plants for the two phenological stages study was founded. In the vegetative root phenological stage was the organ that had the highest concentrations of phosphorus (0.17). Reproductive stage the inflorescence was the body with higher content of phosphorus (0.14). These are preliminary results of the investigation
