SMART HYDROPONIC GROW SYSTEM
The technical team of Projar initiated last June a study about the irrigation and fertigation management in a tomato production located in Murcia (Spain). The objective is to demonstrate that through a monitoring of parameters that affect the crop the plant’s root development can be potentiated when coir fiber slabs are incorporated into the soil. This technique is a newfangled production model known as Soil Improver System which combines both the benefits of soil growing and hydroponic production.
Thanks to the data collected by a climate station and temperature and humidity probes installed into the soil and the coir substrate, we have messure the parameters that influence the crop to adjust the irrigation and fertigation dotations. In this page, you can get more information abour our study, its evolution and the results obtained.
The tomato production where the study was arranged had decreased its production during the last 3 years. This was mainly due to waterlogging of the soil -which causes root suffocation-, excess salinity and inadequate irrigation management.
The firsts results of our study confirm a production increasing up to 40% approximately in comparison with the previous harvest. Even though the initial investment in this technique is higher than a soil growing system, in the first year the productivity revenues are significant, even in the second year of production reaching a productivity increasing up to 30%.
The success of the study has been possible thanks to the crop parameters monitoring that allowed to implement an irrigation strategy based on low volumetric dotations and multi-frequency irrigation adapted to the crop requirements as of the data collected.
