Spain 2020/21

Numerous previous projects have observed increased biomass and reduced water consumption of Secalflor panels for areas with water scarcity. See also:

In Spain, we are currently collecting data in demonstration trials to substantiate these empirical observations. The goal is to determine reproducible results and thus make our application recommendations more precise and reliable.

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

The green beans and the greenhouse tomatoes have a more compact growth with the same supply. There are cherry tomatoes, some pear-shaped varieties and a very tasty traditional variety. We have already been able to measure an enrichment of nutrients in the root zone.

In the open field, on the other hand, lettuces and cabbages are among the traditional cultivation forms with classic flood irrigation. It is precisely here that the effect of the panels becomes apparent in the long term, because they help to keep the moisture in the soil and close to the plants.

The tree species included in the tests range from apricot trees and peach to orange trees. Here, an optimal growth of the trees is existential for the producer. All trees with Secalflor panels grew and developed well in our tests.

We are currently planning studies on the growth behaviour of olive trees, pomegranate and figs under deficient water conditions on Ibiza and Formentera. In particular, the dry soils and the associated salt stress make high-yield agriculture difficult. Thus, the mortality rate for new plantations is regionally up to 25% and more.
