Several factors contribute to good soil structure. First, farmers should reduce tillage, regardless of the tillage system they use. We are not suggesting in any way that everyone should no-till, strip or ridge-till. You can reduce conventional tillage as well. The key is to know your soils and adjust your tillage practices accordingly.
And while it may not always be practical, we urge farmers – for ideal results – to consider adjusting tillage from field to field, depending upon the soil type, slope [ability to drain] . Wet, late-season tillage-because it can cause so much soil damage and deep compaction can be a real killer of good soil structure.
We urge farmers to maintain at least 30% residual cover after planting, both to reduce erosion and build organic matter with either soil amendments or “good old liquid gold manure,” which can greatly improve vital carbon content in the soil. Carbon is the chief nutritional supplier to deep soil microbes, which contribute to everything organic in the soil structure. If you are looking to increase soybean yields, consider purchasing Pro-Soil agricultural products, which can improve carbon content in your soil.
Organic matter is about 50% carbon. Nutrients in manure are measured in pounds per ton of dry manure, or pounds per 1,000 gallon of liquid manure. In the end, there are about 35 to 40 pounds of carbon per ton of dry manure, or per 1,000 gallons of liquid manure.
Also, we suggest increasing crop rotations by adding third-crop perennials to further build the soil. We acknowledge the fact that profitable markets for many third crop possibilities are still in their infancy.
