Sluiten fosfaatbalans Nederland (KB-24-002-023)

Project: EZproject

Project Details

Description

The livestock sector is essential for the position of Dutch agriculture . Due to a relatively high intensity of livestock farming and the import of animal feed, the amount of nitrogen (N) and phosphate (P) produced in manure is greater than can be used in a responsible way on farmland. Without increasing the N and P use efficiency  including manure treatment and P recovery, the imbalance in N and P production versus requirements is not soluble unless livestock production is reduced .

The aim of this project is to provide insight into possibilities for optimizing fertilizer use at regional scale in view of the related expected soil, water and air quality. The project explores opportunities for the Netherlands as a whole and within regions in Netherlands, focusing on improved interactions between livestock farming and arable farming and enhanced export opportunities in North West Europe in view of the quality of organic manure products. The focus is on options for limiting phosphate (P) surplus, but in addition, attention is paid to the interaction with organic matter/ carbon ( C), nitrogen (N) and potassium (K). In 2016, the focus is on the three northern provinces .

Expected results are

  • Current budgets (inputs, outputs and imbalance s) of organic matter, C, N), P and K at various scales (local, regional, provincial, country) in the Netherlands in view of production and crop requirements
  • Effects of a number of scenarios on the mineral (im) balances and corresponding effects on soil quality (trends in organic matter and N , P and K), water quality (in particular, the drain of N and P to the surface water) and air quality (particularly ammonia emissions and greenhouse gases).
