Different kinds of lime can be used. Some change the soil pH more than others. I lists some of the materials available, and gives the value of each. Do not over- lime . Apply lime according to soil test.
Excess lime is likely to result in iron chlorosis of plants.
Soil test recommendation is based on finely crushed limestone. If soil pH is higher than 7.5, which is common in western Nebraska, it may be desirable to lower the soil pH. This generally is not practical for large areas because of cost, but it may be feasible on small garden plots or when the crop to be grown requires a low soil pH, and economic return is high. Amendments such as elemental sulfur, aluminum sulfate, or sulfuric acid can be used. Powdered elemental sulfur is available for purchase and is most commonly used. Table II shows the amount of sulfur to add depending on the texture and the pH of the soil.
