SOIL SAVER. Cover crops and no-till have proven critical to protecting very shallow topsoils from eroding especially when growing cotton. The goal is for each drop of the 50-plus inches of annual rainfall to be slowed by a leaf or stem before it impacts the soil. Bob Walker

Think, Believe, Know: Informed Decisions are Backbone of Walker Farms

Data gathering & long-term testing help Bob & Bill Walker narrow in on efficient no-till crop production

We continually refine our farming system. While my brother, Bill, and I know we’ll never get to specific end goals with many practices like efficient fertilizer use, we’re always chasing and narrowing the gap. 

Our chase is very deliberate. Data from field trials, rigorous soil sampling, imagery and more guide decisions we spend years making. We operate on the premise of think, believe and then know. 

This can apply to most any practice. We might think a certain row cleaner would work exceptionally well in our conditions. We’ll try it side-by-side with another setup. If we still believe it’s a good fit, we’ll try it on a whole planter for a few years. Once the data piles up, and we know for sure, we’ll apply the tool across all our acres.

Our commitment to conservation, and reputation for how we care for the land, helped us build our acreage throughout the years. Here in the hills of west Tennessee, roughly 90% of the farm ground is considered highly erodible…
