Project Details


This research explores maximum standards of bondage to land through 2 farm specific approaches. Motivation for the research is the vision of the Ministry of Agriculture, Nature and Food Quality on a new manure policy where farms, bounded to land, must be able to put all animal manure of their farm on the utilised agricultural area of their farm.

In one approach farm specific placement spaces can fully be filled with animal manure, in the other approach the current rules concerning placement spaces are valid. All standards for placement space must be met. In both approaches it is allowed to use farm specific nitrogen and phosphate excretions.

The approaches will provide 2 types of ‘upper standards’ for bondage to land. The calculations for this are executed with data of dairy farms from the Farm Accountancy Data Network (FADN) of Wageningen Economic Research; the FADN is a representative sample of Dutch agriculture and horticulture. Data from the FADN are processed into input data for the KringLoopWijzer-software (KLW-program) and the KLW-program delivers a large number of output data of which data, needed to calculate ‘upper standards’. So no data from the central database KLW, in control of the Dutch organisation ZuivelNL, are used.

Besides the calculation of the ‘upper standards’ a qualitative assessment of the standard for extensity in WUR-report 3062 will be done to see if this standard has significant less risks on exceeding leaching and runoff standards for nitrogen and phosphate. It will also be shown what are the ammonia and greenhouse gas emissions at extensive and intensive farms.

The report to be delivered, in Powerpoint-format, will contain, among other, tables and graphs to interpret the results more in depth.
