98G, pH, and Tillage Influence on Soybean and Corn Yield


A number of South Dakota soils are developing lower pH surface soils primarily due to the acidifying effect of added nitrogen. Two adjacent studies at the Aurora Farm (Brandt loams) were established to adjust soil pH by either lime or sulfur additions to determine the long term effect of soil pH on corn and soybean yield under both conventional and no-till systems.


Glen Howell, Technical Sales Agronomist

Glen started with Calcium Products in 2008 bringing with him a wealth of experience and knowledge in row-crop production. He supports customers across our sales territories. Glen farmed for more than 10 years until 2004 while also selling and servicing ag and construction GPS equipment for 3 ½ years. Concurrently, he served as an Engineer Officer in the U.S. Army Reserve and Iowa Army National Guard from 1993 until 2004. Prior to joining the Calcium Products team, Glen worked in ag retail for almost five years as a sales agronomist, location manager and agronomy manager. Glen holds two degrees in agronomy and crop science; he graduated from Iowa State University with his bachelor’s in 1993 and completed his master’s in 2013. He is also a Certified Crop Advisor (CCA).


Farming Yields Big Harvest

Large crop yield responses have been measured in some fields containing soils with low organic matter, side-slope landscape position, or coarse soil texture, especially in northeastern Iowa. The objective of this study was to determine S response of com and soybean in north-central Iowa. Materials and Methods Plots were established in 2011 on two sites, one with lower soil organic matter (3.8 to 4.7%) on a Clarion loam with 2 to 5 percent slope (lower organic matter site).


Influence of Gypsum on Crop Yields at South Dakota State University

Gypsum, calcium sulfate (CaSO4 . 2H20), is naturally occurring mineral mined for many purposes. Gypsum has calcium content of 23% and sulfur content of 19%. In agriculture it is used for treating sodium affected soils. The calcium in the applied gypsum will displace sodium on the soil cation exchanged capacity. This is a mass action process; therefore large amounts of calcium are required.
