Take Half, Leave Half
Take half, leave half.
In the grazing community there has been an old saying, "take half, leave half. Here is why it's important for people with perennial clover/legume plots. Look at the chart and see what happens to plant regrowth as you clip lower to the ground. Another consideration is if you clip low and late, you are leaving a lot of plant residue on the ground which can shade or kill off subsequent regrowth.
For those of you who are not as familiar with managed intensive grazing, this is my expertise and It's the concepts i am bringing to the wildlife industry and a focus of my next book. It also is the focus of my 2017 research that I'll continually share with you, the public.
