Abstract

Crop production systems take place in the soil critical (vadose) zone which represents one of the most complex terrestrial systems due to a wide range of processes occurring within its boundaries. As the human population is exponentially rising, large pressure is projected on soil and water resources, as well as on food production in agroecosystems. Numerical modelling can be used as a predictive tool for assessing various crop management systems (e.g. water management, tillage) leading towards more environmentally sustainable production. Simulations can be exploited in designing irrigation or drainage systems, estimating the benefits of various compost addition or implementing (biodegradable) mulch and assessing its effects on the fate of agrochemicals, nutrients, trace elements, pesticides, pharmaceuticals etc.

The approach of combining numerical simulations with laboratory analytics and state of the art field observations has been proven to be very efficient and effective. In homogeneous soil, vadose zone modeling works quite well in describing physical processes and has been proven very efficient for water flow and for estimating/predicting solute transport. However, there is still difficulty in estimation and modelling of preferential flow and non- uniform solute transport in structured soils, which are found in agroecosystems. The issue of non-linearity in vadose zone is mainly connected to heterogeneity in soil properties (chemical, physical and biological) which is difficult to incorporate into numerical models. Challenges including upscaling, model complexity, soil biotic processes and quantification of non-linearity still remains, and improvements in modeling tools are a step towards the solutions.

In this seminar Dr Filipović will provide a short overview of environmental modeling of soil vadose zone processes and a discussion on possible implementation of such approaches within Queensland/Australian ecosystems.

Biography

Vilim Filipović is Assistant Professor of Soil Hydrology at the University of Zagreb, Faculty of Agriculture, Croatia. Dr Filipović received his PhD from the University of Zagreb, after which he worked as a Postdoc at INRA, in France. In his research, he made progress in understanding transport processes in soil by applying novel modelling approaches and examining the possibilities of decreasing environmental pressure originating from agriculture on soil and water resources. His research is focusing on preferential flow and non-equilibrium transport processes in heterogeneous soils, fate of soil contaminants (e.g., nutrients, pesticides, trace metals, pharmaceuticals) and numerical modeling within the vadose zone.

Dr Filipović has led international projects with CEH, INRA, ZALF, BOKU and CSIRO. He is raising awareness of environmental soil physics through teaching and extension activities in the southeastern Europe. Vilim is involved in various committees and boards and serves as an Associate Editor for the Soil Science Society of America Journal (SSSAJ).
