Our humidity sensors become international, they conquered the south of Portugal and now the north of Algeria .

Sensors in Algeria

The entrance to this country has been given thanks to the involvement and collaboration of the agronomist Axel Torrejón , of Chilean origin but based in Cáceres, and a great expert in woody crops, especially cherry trees. Together with Plantae engineers, the installation plan was drawn up on a 600-hectare estate of vineyards, plums, cherry trees and apple trees.

The farm is located near the city of Benchicao in the province of Médéa .

  • 40 sensors have been placed measuring at two depths, at 20 cm and 50 cm in vineyards and fruit trees.
  • Estas fincas están asesoradas por técnicos profesionales de diferentes países: Francia, Argelia y España, aunque la instalación efectuada, referencias y estudio técnico vino de la mano de Axel Torrejón.

The weather in northern Algeria makes the installation of sensors necessary

The northern part of Algeria where we work has a typical Mediterranean climate, with hot and dry summers and mild and rainy winters.

The need for irrigation controlled in the summer is essential for quality control, product quantity, water saving and energy saving.

The salinity problem is also important because it is a coastal area.

Control by sensors indicates in real time the humidity of the crop and this means that we can control the irrigation and this has a positive impact on three fundamental factors:

  • Water stress is avoided.
  • It considerably reduces the accumulation of salts.
  • It saves water and energy.

Algerian agriculture needs a technological boost to expand its commercialization. Plantae technology applied to the control of humidity, temperature, conductivity and salinity is simple and easy to Apply for the farmer. We want to contribute a little technology to the vineyards with the denomination of origin of Médéa and the fruit trees in the area.

Influence of sensors on water stress

As irrigation is more controlled and continued, it makes the plant receive the water it needs at all times.

In this way we avoid water stress, that is, the imbalance between the water needed by the plant and the one provided. In intensive fruit plantations such as this one, the control is basic to regulate the growth process of the plant and the time of fruit formation.

Sensor control favors root development, plant growth and quality of fruit .

In warm areas it is especially important to control the humidity so that the plant does not suffer water stress because with the heat it accelerates the evaporation and perspiration that is the water that the leaf loses within its normal biological process.

Influence of salinity sensors

The accumulation of salts is due to the evaporation of water during hot weather. The salts do not evaporate and accumulate around the wet bulb.

The concentration increases if the irrigation is not controlled and the irrigation interval is very distant and due to the heat there is excessive evaporation.

This forces intense washes that cause salts to accumulate in deeper areas and depending on the type of terrain can generate an accumulation problem that harms the crop.

Ideally, a control that allows the plant to have the necessary humidity and less evaporation.

The type of terrain must also be taken into account. In the stone fruit the free lands are the ideal.

In the Médéa area the grounds are clayey-silty-sandy that easily accumulate salts if it is not irrigated properly. This causes them to seep less with the washes. As the salinity increases the absorption of water by the plant is lower.

If the irrigation is adequate in quantity and periodicity, the salts are absorbed by the plant. Washing is less necessary and the land has a much higher fertility for much longer, because no excess salinity is produced.

Fruit trees and vineyards are sensitive to saline stress. Your control is very important.

We will soon dedicate an article to salinity, its effects and how to avoid it. We have already commented on the correct irrigation of the vineyards .
