Probes in table grapes-The best irrigation if controlled

Table grape probes in Spain control the quality and quantity of the vineyard, one of the most widespread crops throughout the peninsula. We are going to study how irrigation controlled by Plantae sensors can be technified.

Table grapes in Spain

Spain is the main grape producer in the world. The control of its growth phases controlled with precision agriculture will ensure that the quality is the ideal and the quantity is the maximum possible.

In our country, drip irrigation is increasing. Plantae is aware of this and offers the winegrower the best technology for a complete control of the vineyard.

Table grape characteristics

Table grapes need special care throughout their production cycle.

The fundamental cares are:

  • The measurement of cold hours in the latency period.
  • The amounts of hours of sunshine at the time of production.
  • Irrigation and conductivity control because they influence:

The flavor that depends on sugars and organic acids.

Color of the berry that depends on the light and the temperature.

Shape of the bunch, conical, globose or cylindrical and depends mainly on the variety.

Size of the berries that depends on the management of the production.

Loss of berries from the bunch detaching from the stem due to the lack of flexibility of the pedicel that joins the berry with the stem.

Berry texture , one of the qualities that consumers value most.

Irrigation control with probes in table grapes

Stage 1: from the appearance of the buds to the flowering.

Irrigation depends on the uniform growth of the shoots. It is essential to control the water stress of the plant so that its development is regular.

The tendrils should be tender and long. The dryness of the tendrils is a symptom of water stress.

Root development depends on the humidity of the wet bulb and directly influences the health of the plant. The sensor measures the degree of humidity in real time, so that this phase has a stable development.

Stage 2: from flowering to veraison or fruit ripening.

An excess of humidity causes the branches to grow too much and the leaves cover the fruit excessively and impair ripening.

Irrigation control affects the size of the fruit. An excess causes the grape to grow too much and lose quality. The adequate amount of water is in this fundamental phase. Drought means that the berry does not develop properly before veraisoning or ripening.

Water stress seriously damages the harvest.

Stage 3: from veraison or maturation until the harvest is harvested.

The berries stop growing to mature. Now they need very little water. Too much will cause cracking in the grape. The amount of potassium that affects heartburn is also altered.

At the end of this stage, the watering should decrease because the plant begins with the decline in growth and prepares for the winter rest and the excess humidity damages it.

Stage 4: from harvesting to the dormancy of the vineyard

At this point, an increase in water is important, but not as great as in the first phase, so that the roots expand and the plant becomes stronger with a view to the next production.

Moisture is also desirable to protect the roots from the winter cold.

Installation of Plantae humidity sensors / probes in vineyard irrigation for table grapes

The fundamental objective of the installation of sensors / probes is to avoid the water stress of the plant and to control the humidity levels in the subsoil at 20cm, 40cm and 60cm. Information on subsoil humidity, conductivity and root temperature is obtained in real time and available on mobile or tablet, very important data to control irrigation according to the type of soil and time of year.

Plantae sensors / probes measure:

  • The humidity of the subsoil.
  • Conductivity.
  • The temperature of the subsoil.
  • The flow of water.
  • Relative humidity.
  • The amount of rainwater.
