Toevoegen van magnesiumchloride (MgCl2) aan runderdrijfmest : Huidige stand van zaken van onderzoek naar het effect van MgCl 2 in mest op emissies, bodem en gewas
In recent years, research has been done into the working principle and effects of addition of magnesium chloride to (liquid) manure. There is great interest in emission reducing measures in livestock farming, including additives to manure. This has led to a request from the Ministry of Agriculture, Nature and Food Quality (LNV) for an overview in which the currently available knowledge about the effects of adding MgCl2 to manure is brought together and placed into perspective. It can be concluded from the available sources of information that MgCl2 can lead to a reduction of ammonia emissions from dairy barns and that an emission reduction may also take place when manure with MgCl2 is applied to the field. Securing the administration of the desired amount of MgCl2 still needs to be further developed. Positive effects are claimed in terms of fertilization, soil quality and crop production when manure with MgCl2 is applied, but no research results have been found to support or confirm these claims. However, it has become clear that when the necessary doses of MgCl2 per m3 of manure are used, the amount of magnesium and chloride can lead to overfertilization, which possibly leads to leaching or accumulation of magnesium and chloride in the soil and adverse effects on soil, crop and groundwater quality. Furthermore, use of MgCl2 leads to additional operational costs. The effects on soil and crop quality on the long-term are still unknown and require further research.
