Northwest and Allee Research and Demonstration Farm
Agricultural limestone is commonly applied to maintain optimum soil pH for crops. There is insufficient information, however, about short-term effects of different lime sources and application rates on soil pH changes over time and crop yield. This information is needed to improve soil pH and lime management. The objective of this experiment was to study the soil pH and crop yield response to application of pure calcium carbonate, calcitic limestone, and dolomitic limestone.
