3:15 WATCH: In our previous video, Research Microbiologist Dr. Mike Lehman described soil microbes in healthy soils as a “division of labor.” This “division of labor” is extensive and, when cultivated through regenerative practices, works alongside the farmer. In our third and final video, Dr. Lehman takes it a step further and shows us that these…
15 Trillion Laborers w/ Dr. Mike Lehman – Community (3/3)
15 Trillion Laborers w/ Dr. Lehman – Division of Labor (2/3)
3:30 WATCH: If the soil health movement has taught us one thing it’s that healthy soils produce healthy crops. But when we say “healthy soils” what does that actually mean? Well… in short, it means THEY’RE ALIVE! In the second video of our three-part series with Dr. Mike Lehman, we dive head first into the…
Merit or Myth: Season 2
In our first Merit or Myth season, we discussed the issue of no-till in the context of residue management, soil water (mainly infiltration), soil temperature, weeds and economics. In reality, a companion between no-till an conventional till system is very difficult to compare is one only looks at one factor (e.g., residue). When we spoke…
Soil Resilience and Water Holding Capacity
In a lot of ways, farming success comes down to efficiency How efficiently can a farmer make use of his time? How efficiently can he make use of his inputs? How efficiently can he make use of his available resources? When it comes specifically to those available resources, there is one that stands above the…
Economics & Soils: Jorgensen Case Study (Part 5)
One may take the view that soils are a static, medium to grow plants and place nutrients. If one holds this static view of soils, what the Jorgensens have been able to achieve would simply not make sense; at best it would appear anomalous. If one holds the view that soils are living, dynamic ecosystems…
Soil Temperature Part 2: How do No-Till Temperatures Catch Up to Conventional Till?
In our previous video we saw that by the end of the season, there is no difference in the number of heat units and temperature as seen by a conventional versus a no-till soil. In fact any differences in cumulative heat units between the two systems disappears by the first week of July. In this…
Soil Health = Record Yields?
It’s been said that what comes easy doesn’t last, and what lasts doesn’t come easy. This adage is especially true when it comes to change. Any change worth making isn’t going to be done overnight and it isn’t going to be realized without difficulty. One Iowa farm is showing the Midwest though that, when it…
Soil Temperature Part 1: Comparing Conventionally Tilled vs. No Tilled Temperatures
In this video, the USDA-NRCS’s (Brookings, SD) Eric Barsness and SDSU’s Anthony Bly discusses and experiment the NRCS conducted in Vermillion SD on a conventionally tilled and a long-term no-tilled field. Eric buried two temperature probes at 2” and the probes were able to record temperatures every 15 minutes over the entire growing season of…
