Lettuce in Spain, varieties and care-Optimized irrigation with probes

We are going to dedicate this article to lettuce, its varieties and its care. It is one of the latest crops that bets on our Plantae humidity sensor technology > applied to drip irrigation.

It is one of the most used vegetables in the daily diet. It accompanies meats, fish, eggs and is a complement to multiple salads.

Lettuce varieties

  • The Roman: one of the best known and most used. Long and crisp leaf.
  • Lollo rosso: reddish in color and more rounded. Curly shape. Widely used to color salads.

Lettuce care

Controlled irrigation with probes in lettuce. 1-Conductivity probe. 2-Pivoting and abundant root system. 3-Accumulation of salts. 4-Drip irrigation. 5-Wet bulb with humidity and temperature probe.

Lettuce roots are abundant and short compared to the development of the leaf. It is therefore sensitive to the lack of humidity and does not resist drought. But the excess of humidity causes the appearance of fungus. Therefore, controlled irrigation is very important.

The temperature should be medium or high and have many hours of light.

The lands should favorably be frank, because they get less waterlogged. Row planting is important.

Installations of sensors / probes for underground drip irrigation control

  • The first thing is to analyze the terrain.

  • Second, study where it is convenient to put the sensors / probes and the receiving Hub.

  • We place the sensors / probes in strategic areas that control humidity in real time.

It is enough with a sensor, because the root system of lettuce is short as indicated in the previous irrigation scheme. In other crops it is necessary to measure at different depths.

  • Finally, note that the sensor / probe system adapts to all varieties of lettuce.
