We met with Research Microbiologist Dr. Mike Lehman (ARS) on the research station in Brookings, South Dakota to talk soil microbes. Dr. Lehman isn’t just a well-respected scientist, it turns out that he’s also a great communicator. In this and the next two videos, Dr. Lehman takes a shovel full of soil and talks about…
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…
Economics: Jorgensen Land and Cattle Case Study (Part 3)
In our previous video of the Jorgensen Land and Cattle Economics Case Study, Nick Jorgensen discussed some of the economic savings they were able to realize in their long-term, no-till fields where typically Organic Matter measured over three percent. What the Jorgensen land and cattle operation was able to do in this analysis was save…
Economics: Jorgensen Land and Cattle Case Study (Part 2)
In this video Nick Jorgensen provides a simple calculation related to equipment costs and economics based on what Jorgensen land and cattle may have done 30 years ago in a wheat – fallow system compared to today. By not operating tillage equipment and running a sprayer the Jorgensens are saving between $25 and $45 in…
Economics: Jorgensen Land and Cattle Case Study (Part 1)
Economics are a complex issue. At Merit or Myth, we have found that getting farmers to talk about money can be tricky, so we were particularly grateful to find that Bryan and Nick Jorgensen were willing to talk dollars and cents with us! This is the first in a 5 part series on the money…
South Dakota Soils And The Families That Call Them Home
This past week, we were blessed with another opportunity to visit the Mount Rushmore State and pick the brains of several leading farmers in East River. Unlike trips of the past, this go around we paid less attention to the isolated nuts and bolts of farming. These oft-discussed “nuts and bolts” include individual topics like…
What are SD No-Tiller saying About Soil Temperatures
In the previous three videos we have looked at and discussed some soil temperature data from the 2016 growing season in Vermillion, SD. In this video we speak to some long-term no-till farmers from Crooks in the east to Box Elder in the west of South Dakota and gauge their opinions. While all recognize that…
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…
