One step closer to optimal fertilization of clover grass
Clover-grass mixtures are popular because they do not need to be fertilized as much as pure grass crops. Indeed, legumes such as white and red clover are self-sufficient in nitrogen. They can simply fix nitrogen from the atmosphere and fix part of the nitrogen in the soil. In this way, they can actually also provide nutrients for the grasses that also form part of the field's plant community.

What is the Purpose of Hiccuping?
We’re all familiar with (hic) the mildly uncomfortable sensation (hic) that is hiccups (hic). Perhaps you swallowed a bit too much air at once, downed your lunch with incredible speed or took a swig of something overly carbonated or alcoholic. Maybe you laughed at a phenomenal joke for way too long — or maybe you simply became over-excited for no reason at all. The fact is, any one of these things
