Utilizacion de un modelo simple de transporte de agua y nitrógeno en el suelo en las practicas de Horticultura

Simulation models for the transport of water and nitrogen in the soil are useful tools for evaluating the consequences  of  different  crop  management  practices  without  waiting  until  the  end  of  the  crop  cycle.  Particularly,  simple compartmental models for the transport of water and nitrogen are based on the solution of mass balance equations for  the  water  and  a  system  of  ordinary  differential  equations  for  the  nitrogen  cycle.  In this work, these models are used to evaluate different possible scenarios of irrigation and nitrogen fertilization in a cauliflower crop, as a practical work for the students of Horticulture course. The results show that different irrigation and fertilization strategies lead to different results for the nitrate leaching, water drainage and nitrogen uptake
