In Huelva, greenhouse production is expanding, known as the "sea of plastic". Greenhouse sensors are one of our goals in this region, where agriculture has become one of the main drivers.
In its crops, the strawberry and red fruits stand out: raspberry, blueberry and blackberry.
In Huelva a high percentage is of herbaceous cultivation. The climate is Mediterranean with an average annual temperature of about 18º and with more than 3000 hours of sunshine per year, which influences the cultivation of red fruits, and all intensive fruit growing and horticulture.
We also find citrus, almond, peach, persimmon and olive trees with the verdial variety of roe very resistant and productive.
It is estimated that the irrigated area in Huelva is about 4,403 ha.
Red fruit greenhouses
Red fruits are booming in Huelva, especially in greenhouses, and the temperature and controlled irrigation are essential.
Raspberry is very sensitive to frost and extreme heat, it favors soils that retain water but without puddles.The sensors in red fruit greenhouses help to increase production, avoid diseases and improve quality.
The blueberry has a very superficial distribution of the roots and needs a rigorous control of the humidity in the soil, because it suffers a lot from the puddles, especially during the flowering and ripening of the fruit.
Blackberries are usually drip irrigated and are especially sensitive to waterlogging, requiring more water during fruit growth and before pruning.
Sensors in strawberry greenhouses
The sensors in strawberry greenhouses improve production and quality.
In this product, controlled watering is essential, especially in flowering and ripening, which lasts as long as the collection is made.
Last week we installed the Fortuna strawberry variety in Palos de la Frontera, next to the banks of the Tinto river. For this, sensors have been implemented measuring at 20cm and 30cm depth with a frequency of 1 hour each reading.
The strawberry has a production method that involves different phases.
- The first is the acquisition of the plant that comes from the nursery and comes from other provinces such as Ávila and Segovia.
- These plants arrive in Huelva around the month of October where they are replanted.
- They start the collection approximately from December to May, first with collections every 5 days and reaching collections every three days in the hottest months. Hence the importance of starting to monitor with Plantae in the month of January.
- Once the strawberry harvest is finished, the plants are removed (discarded), everything is collected, disinfected and the cycle begins again.
