Question

The soil in a filed is highly acidic list any two materials which can be added to the soil giving specific reason

Answer 1

Nearly all North Carolina soils are naturally acidic and need lime, which neutralizes the acidity, for optimum growth of crops, forages, turf, trees, and many ornamentals. Even though most of these soils have been limed in the past, periodic additions of lime based on soil tests are still needed. Soil-test summaries and field records compiled by the North Carolina Department of Agriculture & Consumer Services (NCDA&CS) emphasize that poor management of soil pH accounts for a high percentage of the “crop problems” in North Carolina.
