Calcium and pH Get the Spotlight in Farm Journal

Earlier this month, Farm Journal posted a good article online.  There are a couple of things we need to help them out on. “The liming process revolves around calcium, as Farm Journal Field Agronomist Ken Ferrie has explained at several sessions of Farm Journal Corn College.” Actually it is the carbonate that changes pH. Calcium merely takes hydrogen’s place on the soil colloid. "Calcium deficiency in plants is rare," Ferrie says. "It’s calcium’s role in the soil, in regulating acidity, or pH, that farmers need to be concerned with." Yes calcium deficiency is rare; however, pH is the measurement of hydrogen (this is where pH comes from, Potential Hydrogen). Calcium has little to do with pH regulation. This is one of the best most concise explanations of what calcium does for the soil; “In the soil, calcium holds the key to healthy structure, Ferrie continues. That’s because a calcium ion has…

"Why is lime important in agriculture?

 There is a good, and short article on Ag Phd's newsletter on page 5, "Why is lime important in agriculture?". We think you will enjoy it too.   Yield Starts Here is a blog for farmers, focusing on increasing yield and profitability by focusing on the soil. It is managed by Craig Dick, a Blogronomist and Sales and Marketing Manager at Calcium Products. Find other articles by Craig and guest writers at .

Poor Wheat Tillering Due to Aluminum Toxicity

  We thought you should be aware of a good article released by the Plant Management Network, originally written by K-State, entitled Poor Wheat Tillering, Root Development May be Due to Aluminum Toxicity. From the Artilce: “…the producer should make a note of this condition (low pH/Aluminum Toxicity) and take action before planting another crop on that field. Lime application on low-pH soil should be considered a high priority. Even half-rates of lime will do some good,”  Dr. Diaz said. “Aluminum toxicity begins to occur where soil pH levels are less than 5.0 and potassium chloride-extractable free aluminum levels are greater than 25 parts per million, Ruiz Diaz said. Some varieties of wheat, such as Everest and Overley, have better tolerance to low-pH soils and high aluminum levels than other varieties, such as Fuller. The symptoms of aluminum toxicity include poor tillering and sometimes, but not always, a purplish color,…

You Can't Afford to Apply Fertilizer Without A Soil Test

Midwest Labs has a great post about why you should soil test. The main reason, the high cost of nitorgen and phosporus. We have been talking about the cost of low pH since 2008, Let's look again at what not knowing your soil pH can cost you. Soil pH testing is the best place to start when planning a fertility program. Having low pH causes plant nutrients to be tied up. According to research done by Midwest Laboratories, a pH of 6.5 ties up 24% of available phosphorus. If your pH is 6.0, then P tie-up increases to 48%, and 24% of N is not available to your crops.   The cost of not liming soil at a 6.0 pH, 200-bushel corn goal:   Nitrogen  @ $0.54/#   24% unavailable    150#'s = $81  $20 /a in wasted inputs   Phosphates @ $0.60/#    48% unavailable    70#’s  = $42/a  $20/a in wasted inputs…

Low Boron and Excess Iron, is there an interaction?

    One of our customers emailed in with some questions. They wanted to know about lower pH levels and higher iron levels & potential correlations and were seeing seeing sub Boron and excess irons in tissue samples. After some research, near as I can tell boron and iron have no interactions. Both are however affected by calcium (See chart 1). More calcium will reduce iron uptake. Boron and silicon help to increase calcium uptake. In low pH excess phosphorus can reduce boron uptake High potassium can reduce boron uptake Boron deficiency Reduces growth of soil bacteria. Poor movement of sugar and carbohydrates in the plant. Affects timing of maturity, pollination, and reproduction. Some old articles on boron and silicon:   What about Iron? Injury due to high soil iron concentrations is not common under neutral or high pH soil conditions. Toxic situations occur primarily on acid soils (<…
