Enjoy The Fall Weather –Take A Walk And Collect Some Soil Samples, Gregory L. Tylka

Integrated Crop Management News

Once harvest is completed, a very productive way to enjoy the fall weather is to collect soil samples for soybean cyst nematode (SCN). In the 1990s and much of the past decade, fall soil sampling for SCN was strongly recommended as a way to scout fields for the presence of this pest. If fields have not yet been tested for SCN, soil samples should be collected for this purpose. But many fields infested with SCN in Iowa likely have already been discovered.

In the last 10 years, conservation tillage has been a popular farming practice to reduce soil erosion and production costs. There are reports of increases in some soybean diseases following the use of conservation tillage, and there is a view that use of no-till would be associated with the increase in disease risks. However, this view should be readdressed in light of site-specific production. Plant pathologists have long understood that tillage effects on diseases may be site specific. We also know that soil texture interacts with tillage practice to affect plant diseases.
