Conservation and utilization of soil fertility is among the key objectives of sustainable cropping system intensification. Cover cropping is a well-established and efficient agro-environmental measure for groundwater protection, erosion control and stabilization of soil organic matter content. Currently there is hardly any scientific information available to quantify cover crop induced mobilization of soil nutrients with low mobility and thereby estimate potential positive effects on a subsequent main crop. Based on soil and plant nutrient analyses for 13 different cover crops and a bare soil control from a field trial, a database for cover crop nutrient mobilization will be established and the effect on nutrient uptake and yield of the subsequent main crop will be determined.

The aim of the proposed study is the scientific study of innovative subdivisions in plant pots. It should be investigated whether an effective interruption of the root zone is possible by lamellas and thereby the long roots formation can be suppressed as well as the hair roots formation optimized. In an experimental study with several ceramic pot prototypes, in which the lamellas for dividing the root zone in different combinations are used (short to long, low to high, narrow to broad), can these influences be for the first time scientifically investigated. This would make it possible to demonstrate the efficacy of internals in plant pots scientifically. It would be also conceivable to demonstrate, that through the stimulation of the hair roots formation the positive effects on plant health can be achieved. Thus, the consequences of stress (partially drought, lack of irrigation and unfavorable locations) may be at least reduced and contribute to the better resistance of the plant. This could be both for indoor as well as balcony, and patio plants beneficial.
