This study was conducted

to define potential sites to establish protected agriculture in

Baja California Sur, Mexico, taking into account weather and

soil variables. A soil sampling was conducted in 51 sites from

October to November 2010; besides, the available amount

of N, P and K, pH and Electrical Conductivity (EC) were

analyzed. Results showed a low concentration of N, high

content of P, and a variant concentration for K. Moreover,

observed pH was alkaline and EC varied from moderate to

low level. Based on the results, it can be stated that Baja

California Sur has different weather and soils in each of its

counties. As a consequence, there are considerable variations

in protected agriculture development. The higher surface

in Baja California Sur, suitable for protected agriculture,

measured in May 2010, was quantified in 6,811,778 ha. Most

of the year is optimal to cultivate under protected agriculture

approach, without the need for additional mechanisms for

weather control. However, during the summer conditions

are suboptimal and it is necessary to introduce means to

decrease high temperatures.
