Manure enrichment means enriching manure with magnesium chloride. Manure enrichment is a relatively new application with enormous potential, as adding magnesium chloride to manure produces all kinds of positive properties.
The reaction that takes place during manure enrichment proceeds as follows:
Magnesium + ammonia + phosphorus > magnesium ammonium phosphorus (struvite).
Struvite is a natural fertiliser that adheres to soil particles. This gives crops longer to absorb the important minerals, resulting in higher crop yields and a reduction in the use of artificial fertiliser.
Another positive effect of the reaction is the binding of ammonia. Ammonia is a strong-smelling gas that is present in barns and is released when spreading fertiliser. It causes odour nuisance and is harmful to the environment due to acidification. Adding magnesium to manure binds the ammonia, improving barn climate and reducing emissions.
Livestock health is of the utmost importance. An improved climate in the barn makes an important contribution to the welfare of the animals. In addition, magnesium has an impact on the farm's agricultural cycle. Healthier and better crop growth leads to healthier and more productive cattle.
"Reduced emissions, less foaming, richer manure"
Together with Wageningen University & Research, Nedmag is conducting controlled research into this relatively new application.
