The Art & Science of Grass, Soil & Cattle
Rediscovering Natural Philosophy
Long ago, what we now call science was known as “Natural Philosophy.” Natural Philosophy sought to understand both the causes and effects of nature and the full physical universe. Back then they had to measure what they could and guess the rest. Over time, more was measured and less had to be guessed. But as we dug deeper into the mysteries of the natural world, scientists became more narrowly specialized. Unintentionally, science often lost or just forgot context for the wholeness of natural systems.
In our view, further progress in science requires that we relearn how the pieces of nature actually fit together. The library of information in our field of nature involving cows, grass and soil is still growing. Below you will find just a few of the key bits and pieces that will give you a sense for the new Natural Philosophy basis of our direction:
For those that like deep details, here’s a set of select scientific papers that are a good place to start:
Stanton, R. L., C. A. Morrissey, and R. G. Clark. "Analysis of trends and agricultural drivers of farmland bird declines in North America: a review." Agriculture, ecosystems & environment 254 (2018): 244-254.
Industrial agriculture's use of pesticides and its effects on habitat loss have been devastating to birds. Grazing is NOT the problem (but may be a solution?).
Teague, W. R., et al. "Grazing management impacts on vegetation, soil biota and soil chemical, physical and hydrological properties in tall grass prairie." Agriculture, ecosystems & environment 141.3-4 (2011): 310-322.
THE foundational paper documenting changes in vegetation, soil carbon, water infiltration and microbiology as a function of grazing systems.
Demonstrates that a change to “multi-paddock” grazing leads to a net greenhouse gas equivalent sink in most scenarios and a breakeven in the worst.
Using data from Teague (2011), models how better grazing can have large positive impact on water infiltration and runoff.
Does the math to show that at scale, changes to grazing (and no-till cropping) can turn agriculture into a very large net carbon sink.
Millions of years ago, in the age since dinosaurs, co-evolution of grazers and grasslands appears to have cooled the planet a few times already.
A deep dive into the magical relationship between roots, fungi and bacteria within soil that leads to net accumulation of carbon-rich organic matter.
Fascinating technology to measure the carbon going in and out of a pasture everyday to more deeply understand greenhouse gas dynamics. Documents case of active pasture sink.
McAfee, Alison J., et al. "Red meat from animals offered a grass diet increases plasma and platelet n-3 PUFA in healthy consumers." British Journal of Nutrition 105.1 (2011): 80-89.
An experimental study of how just 3 servings per week of grassfed beef and lamb actually caused measurable differences in blood lipid markers.
A forward-looking synthesis of what we do and don’t know about healthy meat (and dairy) and how the magic of real, whole food likely lies in many dimensions that we still don’t fully understand.
