It is common to see homeowners purchase one bag of lime when they purchase one bag of fertilizer. Based on an average lawn size of 5000 square feet, one bag of fertilizer may be sufficient. Applying one bag of lime over 5000 square feet, however, will have little significant effect on soil pH. By sampling, growers can potentially save money that might otherwise be spent on unneeded lime and fertilizer. For example, growers of flue-cured tobacco often routinely apply phosphorus. Growers who do not sample may penalize themselves by having to replant or replace their crop later due to either inadequate or excessive nutrients.
Soil sampling analysis is a free service for any grower in North Carolina.
Most other states in the southeast charge for this type of information and analysis. Sampling supplies and information are available from your local agricultural advisors or the Agronomic Division in Raleigh.
