In order to know the dynamics of calcium absorption in sunflower seedlings, an experiment was established under laboratory conditions, at the Universidad Tecnologica de Tehuacan, to evaluate five levels of Ca(CO3)2 in the solution. The variables were: absorbed calcium, pH, electrical conductivity, root length and volume, which were evaluated under a completely randomized design and four replicates (5x4) = 20 experimental units. The results indicate that sunflower can absorb Ca++, in solutions up to 160 mg L-1 and support, pH levels of 10.5 and 6.5 dSm-1.The length as well as the root volume decreased as the calcium concentration increased. From this research it can be concluded, that sunflower can grow and absorb calcium, at concentrations of 160 mg L-1 Ca++ in the solution.
