Hypomagnesaemia and Grass Fertilization in the Netherlands

The nitrogenous fertilization of grass has made great headway in Britain since the war. It is of interest, therefore, to record experience from the Netherlands, where grass is even more heavily fertilized, concerning the practical control of grass tetany in milking cows, a topic that was touched on in Outlook, III, No. 4. The primary requirement is to maintain an adequate magnesium level in grass by avoiding luxury absorption of potassium.
