Symborg reduces the negative effects of reused and/or highly saline water

19 June 2018
  • Symborg Microorganisms enhance water potential and stomatal conductance in crops
  • CEBAS-CESIC hold iWARESA 2018 a conference on water reuse and salinity management

Symborg microorganisms have proven to be very beneficial for crops subjected to adverse environmental conditions such as highly saline soils or irrigation with reused water. Scientific trials performed in collaboration with the Department of Irrigation of the Centre for Soil Science and Applied Biology of the Segura, CEBAS-CESIC, show that plants inoculated with Symborg products are better able to tolerate conditions of high salinity, water shortage or irrigation with reused water. These microorganisms work to improve the water potential of plants and their stomatal conductance values.

The full conclusions from these scientific trials were shown to delegates of the first edition of iWARESA2018, a conference on water reuse and salinity management organised by CEBAS-CESIC and the International Water Association that was held in Murcia from 11 to 15 June. This scientific meeting discussed the problem of water shortage induced by climate change in arid and semiarid areas. The delegates discussed non-conventional water sources for agriculture and the risk of salinisation of agricultural land and subterranean water in areas where the aquifers have significantly depleted; this is the case in the region of Murcia and many Mediterranean areas where the water and salt levels are the main limiting factors for a more productive and technical agriculture.

Higher levels of calcium, potassium and chlorine

The conclusions of the study that Symborg presented to the scientists attending the Conference were that “the effective association between species of microorganisms and plants under specific environmental stress is a difficult and challenging task”. The scientific trials were performed on adult plants of Viburnum Tinus L. subjected to irrigation with normal water and with wastewater after regeneration treatment. In both forms of irrigation, the plants were inoculated with the arbuscular mycorrhizal fungus patented by Symborg, Glomus iranicum var tenuihypharum, and other microbial complexes.

Plants irrigated with wastewater were negatively affected by salinity as a consequence of the osmotic effect. However, after the application of the microorganisms, the Ca/Na ratio of the leaf increased and the Cl content reduced. Inoculation had a positive effect on the mineral content of the plants and improved the water potential of the stems and the relative chlorophyll content.
