Pasture Management

The current cost of fertilizer, corn, and land has many livestock owners wondering how to stay profitable. Unfortunately there are not quick solutions. This article on nutrient cycling in pastures should help. I have condensed it for quicker reading.  Appropriate pasture management can enhance the nutrient cycle, increase productivity, and reduce costs. Two practical indicators of soil health are the number of earthworms and the percentage of organic matter in the soil.

Soil acidity

Within any given soil, there are two states of acidity that need to be accounted for before liming recommendations can be made. First is the active acidity, which indicates the current pH status of the soil. Active acidity accounts for the H+ ions in the soil/water solution that the laboratory measures. What active acidity doesn’t account for, however, is the reserve, or potential acidity. Think of a swimming pool that has a few people in it, those people represent the active acidity. Now, imagine that there are more people outside the pool, just waiting to jump in after some of the others leave. Those folks represent the potential acidity. When we determine how much lime we need to neutralize the acidity in the soil, it is really the potential acidity that needs to be accounted for. To neutralize the active acidity is easy and requires little lime, but the potential…

How will dry soil conditions alter your soil tests?

I read a great piece in titled “Nutrient management related to dry soil conditions" and wanted to share it. A few key points I'm quoting from the piece: Unfortunately if dry soil conditions continue, soil samples taken this fall (if the ground is soft enough to get a sample) may provide misleading results for K. Soil test K has been shown to vary substantially with dry conditions.  Soil pH measurements are also affected by dry soil conditions. With a dry season and poor plant growth much of the fertilizer added this spring and last fall remains in the 8-inch sampling zone. Higher than normal salt (fertilizer) levels affect the way the pH electrode functions and will produce a pH reading about 0.5-1.0 pH units lower than the actual pH. In addition, soil moisture has been insufficient for normal amounts of limestone reaction in soils limed this spring or last fall. Therefore, soil pH…

I tested a car and found cars to be unreliable!

Last week was the lime conference in Portland Oregon, were we meet some really smart people and a lot of new friends. One of those new friends sent me a note this morning.   Craig,   I read a response that stated the following:  "Studies at Michigan State University found the Pelletized Lime to have a Slower Rate of Reaction Compared to Good Quality Ag Lime Applied at Recommended Rates."  Craig, Because of the Surface Area of Pelletized Lime Being Greater than the Surface Area of Regular Ag Lime, How can a University Make this Statement?  You and I both know that the Surface Area of the Calcium Carbonate in Pelletized Lime is Far Greater than the Surface Area of Any Ag Lime.   Thanks, Gene     My Response: Gene, Picture source: The Yugo is known as "The Worst Car in History"   The problem is two-fold:   Most…
