February Agriculture in Compostela, Mexico

Crop Layout

Located in a sub-tropical area, Compostela, Mexico would have the sustainability for agriculture to produce crops at all times of the year. In order to do so, Chinampas or irrigation ditches were constructed before the Spaniards arrival to supply water to those crops during the drier seasons. First, Lagunas, used as reservoirs, were formed to provide water. Then irrigation channels were arguably constructed to provide a system of soil replenishment, and year around sources for water. Higher in elevation there would be a temporary water source from runoff that would feed the main crops during the wet season flooding the fields, and adding nutrients to the soil.

It is not documented that the Aztecs constructed the San Pedro Lagunillas to provide resources for agriculture in the Compostela valley. However, Elisee Reclus, provides the account of Mendoza renaming the lake after the area provided oak trees for a church. Providing proof that this man made resource was developed by the indigenous populations. Regulating water systems is evidence for a sedentary society. While it cannot be attributed to the Aztecs, some indigenous populations used the technology of the Aztecs to provide an irrigation system to the valley below.
