Abstract
Today it is very common to use simulation models in agriculture, in order to estimate, for a wide range of natural environments, the behavior of some variables in one way or another to predict a specific performance. These models usually include complex mathematical models in software and may come to predict the impact that could result in a system of land management on water in particular and the environment in general. Moreover, estimation of the global climate change effect on the ground is also possible through these tools. But they require input data that sometimes is not readily available as in the case of the physical properties of soils, and within these, those related to water operation. Sometimes data does exist but because of the method used in collection and the way they are expressed, their use in simulation models leads to results that are far from what actually occurs in the natural environment being studied. The study shows the most used physical properties in some of the simulation models which have been used in our country as well as their manner of being expressed and the recommended method for its determination in the field.
