Section overview
Description
Research activities can be subdivided into five main areas:
(1) Basic research on crop nutrient acquisition. This includes the understanding and manipulation of processes in the rhizosphere and in the rooting zone such as nutrient availability and acquisition, nutrient turnover processes, rhizodeposition, and interactions between roots, mycorrhiza and plant growth promoting rhizobacteria (PGPRs).
(2) Environmentally sound, demand oriented and sustainable fertilization strategies. Aiming on high yields and top quality of agricultural products, this area covers the impact of fertilization on soil and environment (e.g. trace gases, leaching, humus balances) as well as the development and adaptation of innovative fertilization strategies in agricultural systems of different intensities (e.g. optimised basic fertilization (P & K), Cultan, nitrification inhibitors, fertilization scheduling, fertilization of renewable primary product crops and return of their residues into the soil)
(3) Soil fertility management and fertilization in organic farming. Beside the maintenance so soil fertility in the long term (e.g. humus balances), specific questions focus on organic fertilization in organic vegetable production, on P-availability in soils and P/K-fertilization under organic cultivation and on the utilisation of bio-effectors.
(4) Renewable raw materials and energy plants. First focus is the optimization of the fertilization of renewable raw materials and energy plans, including the return of processing residues. Second focus is the impact on nutrient and humus balances of the soils.
(5) Global change. The reduction of negative impacts of agricultural production is one of the key issues (e.g. trace gases relevant for the climate). Further issues are dealing with the adaptation of the agriculture to changing environmental conditions (e.g. impact on humus dynamics, adapted fertilization strategies).
