The olive tree is one of the oldest and most appreciated trees along the Mediterranean basin, where 80% of world production is concentrated.

The olive tree is known in Spain since the Romans brought it and its production continues to grow. Especially in the central and southern zone. 25% of oil production is of Spanish origin, mainly from Andalusia. Cooperatives and appellations of origin abound in this Community. It is currently the country with the largest area of ​​olive groves in the world.

Plantae does not sell a plant or advise on the variety or type of olive to be planted in your area or region . We are dedicated to the design, development and commercialization of wireless sensor technology for saving water and improving crop production. Plantae technology is very important in olive trees. That is why we will collect information on the Olive in Spain , its varieties and its need for irrigation control.

Irrigation of the olive tree in Spain

A good part is of dry land and another one of irrigation. The areas with the highest production and quality are the ones with the highest rainfall. The areas of dry land are increasing, for this reason it is increasingly common to resort to irrigation and even better if it is controlled.

Irrigation can be located or drip. It is necessary to avoid waterlogging and in general the excess of humidity that can favor the appearance of fungal diseases that affect the olive tree and the fruit.

Many areas of intensive and superintensive olive . In this case, controlled irrigation is especially important and plants play a very important factor with the installation of sensors that can even be buried for the convenience of farming tools.

The farmer can have real-time information on the humidity and conductivity of the cultivated area.
