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

Introduction

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.

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.
