Microbiome: Now that is a complicated word for a country boy that is very dependent of and thankful for Word and Spell Check. With all its complexity and lack of understanding, I am going to predict that the study, and understanding of microbes (bacteria, fungi, viruses and other one celled organisms) and the role they play in virtually every living thing, will ultimately be one of the most important discussions and understanding of the world we live in that modern science has ever taken on. Simply put microbes are everywhere, some are considered to be bad, but most are beneficial and are being found to be key combaters of the bad ones. Overall scientists are finding microbes are important to our health along with the health of livestock and the rangeland resource. (Early on many believed that virtually all microbes were bad and needed to die, thus the rampant use of antibiotics, that paradigm is changing quickly.)
As we begin to recognize how important soil health is to our rangeland resource and how positive change can quickly occur. It is also being seen that microbe activity within that soil profile are not only the result of good grazing management practices but given the opportunity those microbes move the soil health forward, thus making the rangeland that much more productive. Microbes along with ‘critters’ like earth worms and dung beetles are what breaks down manure, old grass, leaves and wood into humus and are also responsible for the wonderful aroma that fresh tilled soil produces. (Try sticking your finger into a heavily grassed area and smelling the dirt, then scratch that finger into bare soil. The difference in smell is very noticeable.) The trick is to provide an environment for those ‘little fellers’ to flourish. Bare ground and poor soil moisture are not the environment they need. Through a good grazing management program, the soil profile is improved so moisture is retained and a food source (decaying plant material) is available to those microbes. Once that process is established the soil profile begins to improve at an exponential rate- if the grazing program remains active- revert to a poor grazing management regimen and the process will cease, taking the condition of the rangeland back to its original depleted state.
Neat thing is we don’t have to buy any microbes from a dealer, all that is required is apply the proper management and the little critters do it on their own. Trash farming or no till as it known to some, can result in amazing transition. One farmer I know, after initiating his ‘trash farming’, took his tilled soil from 0.3% humus to 3.0% in just three years. Rangeland soil health improvement is very notable within a few years of instigating an effective grazing management program.
Improving cattle health has numerous opportunities with the use of microbial research not only for the digestive system but even the respiratory system. The understanding of these relationships of environment-plant-animal and human health and their relation to the microbes around us has great potential.
A good article suggesting these relationships can be found in Drovers Journal.
Another source of information is:
Engelmann or Cut Leaf Daisy in full bloom. The pasture pictured will not have livestock in it until May 15, plenty of time for the highly preferred grazing plant to secure its perennial root and reproduction systems, so that it can be available next year for increased grazing capacity. Yes, it will be grazed during a slightly different season the next grazing cycle.
