Phosphorus (P) is one of the most important elements for the plant growth and the limitation
in its availability at the beginning of the vegetative cycle can result in restrictions on the
development of the plant, thus, the plant does not recover even if that phosphorus is later
supplied at optimal levels. However, the supply of phosphorus is essential from the
beginning of plant growth (Grand et al., 2001). However, tropical soils have a low

Phosphorus (P) is one of the most important elements for the plant growth and the limitation in its availability at the beginning of the vegetative cycle can result in restrictions on the development of the plant, thus, the plant does not recover even if that phosphorus is later supplied at optimal levels. However, the supply of phosphorus is essential from the beginning of plant growth (Grand et al., 2001). However, tropical soils have a low concentration of soluble phosphorus ranging from 0.05 to 10 ppm, and more than 80% of phosphorous has no mobility, and neither is available for absorption in plants due to adsorption, precipitation or conversion in organic form (Holford, 1997). In order to alleviate this deficiency, large quantities of soluble fertilizers are commercially available. Although natural phosphates have lower agronomic efficiency due to low solubility, especially for annual crops, they can be an alternative to substitute these soluble fertilizers for the more gradual release, which reduces the phosphorus fixation process in these soils (Machadoand Souza, 2012).
