Zeta Amaltea conducts several services in the field of agricultural water, especially aimed to irrigation applications.
Irrigation means about 70% of all water use. Irrigation water needs will be higher in the near future, due to the combined effects of global warming and population growth. Hence, improving irrigation practices is an urgent requirement.
Irrigation can be significantly improved using the right technology. As a starting point, the most suitable irrigation system should be considered. Changing from flooding irrigation to pressure systems such as sprinklers or drip irrigation can save thousands of litres, although it might be expensive in some sites and requires a careful study before investment.
Spain has conducted an impressive modernisation of its irrigation systems. We have the technical experience required to design and build the irrigation system to suit any particular area or crop. Zeta Amaltea can provide the entire equipment for the best irrigation system. We are closely related to AERYD, the Spanish Association of Irrigation and Drainage, representing through its members one of the most advanced irrigation technology in the world
We can also help in irrigation management. Crop water requirements can be provided daily to users from meteorological stations. The automatic meteorological station will measure all the variables needed for daily calculations of Penman-Monteith evapotranspiration, as well as daily precipitation. Data will be processed and sent to users, who will know their local crop water requirements.
We are completely equipped to measure soil properties. We can provide in situ measurements of basic soil physical properties such as texture and density. Besides, we can estimate the soil hydraulic properties and irrigation-related properties such as field capacity and wilting point, using Pedotransfer functions as well as disturbed and undisturbed samples.
Modelling simulations are calibrated and validated in field conditions, using soil moisture sensors placed in selected plots and depths.
We simulate all the process in the soil-physics-atmosphere-plant continumm, using updated physically-based models, as well as the most reliable technology available.
