Coming events:

The 2019 annual meeting of the working group is planned for Tuscany, Italy.

Focus of working:

This working group provides a forum in which researchers working in diverse aspects of fertilisation and irrigation in vegetable crops can exchange information, experiences and feedback, and develop collaborations. With a membership from throughout the EU members' interests cover a wide range of fertilisation and irrigation issues. The general objective is to develop tools and strategies for sustainable nutriengt and irrigation management achieved through optimal management. This is being achieved through two general research lines that are apllicable to both fertilisation and irrigation which are : (1) determination of accurate recommendations, and (2) monitoring systems to ensure optimal management throughout a crop.

In the case of fertilisation, our interest is in recommendations schemes that consider nutrients supplied by the soil which includes available nutrients, and nutrients mineralised from soil organic matter, organic amendments and from previous crops. Monitoring approaches that are being examined to ensure optimal fertilisation include various proximal optical sensors, sap analysis, tissue testing, soil solution analysis and soil analysis. All nutrients are being considered; however, there is a strong focus on nitrogen and also on phosphorus. Additional fertilisation issues being addressed are: rotation effects, crop residue management, organic nutrition, and methods used for analysis of soil, plant and substrate.

For irrigation, our interest is in the accurate determination of site-specific crop water requirements, and in the use of soil moisture sensors as a monitoring approach. With soil moisture sensors, research is focused on developing relevant management strategies, automation of irrigation and assessing sensor performance. In southern regions, soil salinity management is being addressed.

Decision Support systems (DSSs) are being developed to assist with the preparation of nutrient or irrigation recommendations; in some cases both. With some DSSs, data from sensors provides a feedback to adjust irrigation or fertiliser plans.

The working group has over 100 members from 21 countries.
