Research

Newly purchased measuring devices for soil physics laboratory analyses are being systematically tested and the procedure further developed. As part of the project, standardized measurement protocols (Standard Operating Procedure, SOP) are being created and internal workflows and data management (including QA/QC, metadata, and interfaces) are being optimized to increase the accuracy, reproducibility, and efficiency of the analyses.

Sustainable use of irrigation water is crucial to securing agricultural production and conserving water resources. Modern technologies and innovative strategies offer promising approaches to increasing irrigation efficiency while reducing water consumption. Since 2018, various irrigation systems and methods have been tested at the Obersiebenbrunn Agricultural College, with weather data, soil and plant water status, and yield data being recorded. As part of this research project, data from the 2025 and 2026 growing seasons will be analyzed to investigate how different irrigation strategies affect water distribution in the soil, plant water stress, and yields. In addition, the practical suitability of the sensors used for precise irrigation control will be evaluated. The aim is to develop innovative solutions for resource-saving and efficient irrigation that meet the challenges of climate change.

Agricultural production in Austria is heavily influenced by water availability and climate change, which pose significant challenges, particularly during periods of drought. In some regions of Austria, irrigation of agricultural crops is a crucial factor in compensating for insufficient rainfall and ensuring agricultural productivity. Projections suggest that irrigation demand could nearly double by 2050 compared to current levels. To safeguard agricultural productivity while sustainably managing natural resources, adaptation measures are essential. In particular, efficient and water-saving solutions must be developed in the field of irrigation. The Austrian Strategy for Adaptation to Climate Change recommends the use of modern technologies to optimize irrigation systems in terms of timing and quantity. Support measures under the CAP Strategic Plan promote investments in innovative irrigation systems, but their efficiency and impact must be evaluated. As part of an evaluation study, key research questions need to be addressed: How can the efficiency of irrigation measures be assessed? What data are required to demonstrate the water-saving potential of irrigation systems? And how can a state-of-the-art standard for new irrigation systems be defined?
