MARTINEZ-CORRAL, L. et al. Software for the compute of nutritious solutions. Rev. Chapingo Ser.Hortic [online]. 2009, vol.15, n.2, pp.149-153. ISSN 2007-4034.

A Software was developed for the formulation of nutrient solutions based on the universal method proposed by Steiner. The system contains a calculation module that allows to configure the formula according to the anion:cation ratio, total ionic concentration and the required pH. The interface includes automatic adjustment of the contributions of the chemical composition of the water for crop irrigation, as well as the management of a database that allows different combinations of fertilizers. User can access to a configuration menu to choose nutrient sources increasing by this way the portability of the system and facilitating the computation of solutions. By taking into account the results, the system presents more flexibility when eliminating the problems associated to the manual calculations and the restrictions to those that at the moment are subject the algorithms and the traditional spreadsheet focused to this end.
