The subsoil temperature sensor is demanded by the horticultural sector to know the temperature at different depths in addition to other crops such as grass within the garden.

This new data will allow controlling the temperature in the subsoil and comparing the data with the ambient temperature and others

Subsoil Temperature Sensor Applications

  • Temperature control on land at different depths.
  • Know the temperature of the roots which indicates the beginning of the root activity of the crop.
  • Compare the data with the ambient temperature and other parameters to make growth models.
  • Identify the best time to start with the nutritional and water contributions.Sensor de temperatura de subsuelo Plantae

Technical data of the subsoil temperature sensor

The temperature of the agricultural soil conditions the microbial processes that take place in the soil. Temperature also influences the absorption of nutrients, especially phosphorus, which is lower in cold soils.

Soil temperature is important because it influences:

  • In biotic processes.
  • In chemicals.
  • For germination that is normally above 5ºC and that is measured in real time with the subsoil temperature sensor.

Each plant has its specific requirements.

The surface layer of agricultural soil suffers the greatest temperature fluctuations. The temperature of the surface layer is transmitted upwards to the air, and downwards to lower layers of the soil and subsoil, rapidly damping mainly downwards.

Water, an essential resource in plants, can be a scarce commodity on many occasions, making many crops dependent on irrigation. A new study shows that the temperature of the soil influences the way in which the plant acquires this resource. According to the scientists, if the soil temperature decreases, even with enough water to meet the plant's demands, trees such as olive and almond trees have more difficulty in acquiring water resources.

Edaphic study

Since the synthesis of hormones and other substances occurs in the roots, in addition to the intake of water and nutrients, the temperature of the root zone has marked effects on the growth and development of the plant.

In general, the growth and development of the plant increases with increasing edaphic temperature to a maximum level between 25 and 35 ° C, depending on the species; in the same way, there are minimum edaphic temperatures (between 8 and 15 ° C) for development.

Each species has its own edaphic temperature requirements at different stages of its development.

Given the greater sensitivity, the plant in its initial growth (germination and seedling state) requires higher edaphic temperatures than in the maturation processes of its organs.

The underground organs of plants do not have the ability to regulate their temperature, so cardinal temperatures (minimum, optimal and maximum) for root functions and tuber development are more marked than for aerial organs.

The cardinal edaphic temperatures depend on the origin of the species; tropical plants generally develop best between 20 and 25 ° C.
