This plot has been implemented in Octave and R.

Modern computers' superior graphic capabilities have meant these techniques are less often used. The popularity during those years is attributable to their use of monospaced (typewriter) typestyles that allowed computer technology of the time to easily produce the graphics. Stemplots became more commonly used in the 1980s after the publication of John Tukey's book on exploratory data analysis in 1977. They evolved from Arthur Bowley's work in the early 1900s, and are useful tools in exploratory data analysis. Interested in the Total Grazing online course?

But an adapted cow and under good management. This is why, I say: As the cow needs the grass, the grass needs the cow. The process of Total grazing, that includes non-selective grazing will give a higher leaf production per square yard per year and a plant with much more energy for your livestock and to improve your soil. Selective grazing will lead to less leaf and more stems That was the reason of the low productivity in that pasture.Д®verything hinges on our grazing management.

What I found was 97% stems and brown leaves and only 3% of green leaves. I have measured this on common Bermuda where selective grazing had been done for a long time as we know, selective grazing results in less leaf production, less energy in the plant, and a higher proportion of stems and brown leaves that inhibit the formation of new leaves. Once you do this, you will get experience to judge the leaf to stem ratio in your fields.Д¬ool season grasses normally have better leaf to stem ratio than warm season perennial grasses. It is important you do this exercise at least once it will come as a big surprise. This way we can know for certain what percentage of our grass is green leaves and what percentage is stems and brown leaves which do not do photosynthesis. Also divide the weight of the stems and brown leaves by the initial total weight. We need to remember that stems weight much more than leaves.ДЎ.- Cut one square yard of grass flush with the soilДЈ.- Separate the green leaves from the stems and brown leavesД¤.- Weight them each in their own separate bagДҐ.- Divide the weight of the green leaves by the initial total weight and you obtain the percentage made by green leaves. Now, how can we quantify how much leaf, by weight we have in relation to stems? This means your cattle will have better nutrition when they consume more leaf. We also know that leaf has higher digestibility, 60-70 percent while stems only have around 30-40 percent. This is so due to the leaves producing energy through photosynthesis and the stems consuming energy by respiring. It is a virtuous cycle that depends on the leaf to stem ratio.

These soil microorganisms, in return, make nutrients in the soil available to the plants. As we know, the leaf to stem ratio determines the level of available energy for growth in the plant and how much energy can be used to feed soil microorganisms by root exudates.
