FARMING FRUIT AND VEGETABLES -
FIELD TRIALS IN SPAIN

Spain 2020/21

In numerous past projects, Secalflor panels have demonstrated increased biomass production and reduced water consumption in areas affected by water scarcity. See also:

We are currently collecting data in demonstration trials in Spain to support these empirical observations. The aim is to determine reproducible results and thereby make our application recommendations more precise and reliable.

But even in modern production facilities, water and nutrient savings are crucial for producers’ economic survival. Together with growers, associations, and cooperatives from the Murcia region, we are testing the application of the panels at different depths and in combination with different irrigation intensities.

Green beans and greenhouse tomatoes grow more compactly with the same nutrients. These include cherry tomatoes, some pear-shaped varieties, and a very tasty traditional variety. We have already measured an enrichment of nutrients in the root zone.

Outdoors, however, lettuce and cabbage are grown using traditional methods of cultivation with classic flood irrigation. This is where the long-term effect of the panels becomes apparent, as they help retain moisture in the soil and near the plants.

The tree species included in the tests ranged from apricot trees and peaches to orange trees. Optimal tree growth is vital for the producer. All trees with Secalflor panels grew well and developed well in our tests.

We are currently planning studies on the growth behaviour of olive trees, pomegranates, and figs under deficient water conditions on Ibiza and Formentera. In particular, the dry soils and the associated salt stress make productive agriculture difficult. For example, the mortality rate of new plantations can reach 25% or more in some regions.
