The Claim
Pasture soils contain 1.4 times higher organic matter and 1.7- to 3.0-fold higher concentrations of potassium, phosphorus, and calcium compared to paired cornfields used for feedlot cattle feed.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Soils under pasture grazing have 40% more organic matter and 1.7 to 3 times more potassium, phosphorus, and calcium than soils in cornfields grown to feed cattle.
See the scientific wording
Pasture soils have 1.4 times higher organic matter and 1.7- to 3.0-fold higher levels of potassium, phosphorus, and calcium than paired cornfields used for feedlot cattle feed, indicating improved soil health under pasture-based grazing systems.
Rich soils with more organic matter and minerals like potassium, calcium, and phosphorus help plants grow better and make more natural chemicals. Cows eat these plants, and their bodies break down those chemicals into new compounds that build up in their muscles. These compounds help reduce damage from natural body processes and improve energy use in muscle cells.
What the research says
1 studyThe study found that soils where cows graze on grass have much more natural stuff (organic matter) and important minerals like potassium, phosphorus, and calcium than soils where corn is grown to feed cows — just like the claim says.
