01What is being requested

The research concerns the restoration of the nutrient balance in dry heathland by means of P-addition and possible restoration of basic cations. The contract has a duration of 36 months with a maximum value of € 400,000 excl. VAT.

The research focuses on the restoration of the nutrient balance in dry heathland that has been ploughed in the past. Although previous plough management has led to a reduction in nitrogen, it has also led to increased phosphorus limitation and reduced availability of basic cations, with negative consequences for flora and fauna. As a result, many ploughed heathland vegetations have remained species-poor. P-addition, whether or not combined with the restoration of basic cations, is seen as a possible follow-up measure. However, the applicability, effectiveness, and sustainability of this have n

12Frequently asked questions

What is the specific objective of the research into the N:P balance?
The research focuses on the restoration of the nutrient balance in dry heathland that has been ploughed in the past. In this, it is investigated how P-addition, potentially combined with the restoration of basic cations, affects the effectiveness, applicability, and sustainability of the restoration measures on soil, vegetation, and fauna.
Which suitability criteria must bidders meet?
Bidders must have demonstrable experience with soil nutrient research in Natura 2000 areas or similar natural areas. In addition, competencies in the field of soil chemical analyses, GIS, and ecological monitoring are required, as well as the ability to realize a conclusive research plan within the stated duration.
Which specific research questions must be answered?
The research must provide insight into the current status of nitrogen, phosphorus, and buffering in ploughed and chopped dry heathland, the long-term effects of P-addition and buffer restoration on soil, vegetation, and fauna, and the conditions under which P-addition can be applied effectively, safely, and sustainably.
What are the required qualifications for the execution of the research?
Bidders must possess adequate research capacity. The execution of the research is carried out by an executor who performs the work on the basis of the Research Plan submitted by the contractor.
