Crop Sequence and nutrient acquisition from the subsoil

Title: Crop Sequence and nutrient acquisition from the subsoil
Abstract: The research unit aims to describe and quantify processes in, and the amount of nutrients released from, the agricultural subsoil. The creation of biopore systems, soil structure dynamics, microbial activities, water dynamics and nutrient transformation processes will be described and quantified.
The Institute of Crop Science develops a numerical model which describes mobilisation, transport and uptake process of nutrients from the subsoil by crops at the field scale.
